## Built for

- Frontend engineers shipping fast
- Indie hackers & solo founders
- Design engineers who want their own component slots
- Teams standardising on Zod

## Highlights

### One-line form definition

Hand it a Zod schema and you get a fully-typed, accessible form — labels, error states, focus management included.

### Composable when you need it

Custom component slots, field overrides, conditional fields, multi-step wizards. The escape hatches are first-class.

### Looks good out of the box

Shadcn-style with Tailwind. Light & dark mode. Bring your own theme tokens and everything tracks.

## What's in the box

- `FormGen component` — the main entry point
- `useFormGen hook` — for custom layouts
- `8 field components` — text, number, date, select, etc.
- `Wizard layout` — multi-step, optional
- `Conditional fields` — show/hide by value
- `TypeScript types` — fully exported
- `Tailwind theme tokens` — override anything
- `Full source + docs` — no obfuscation

## Works with

- **React 18+** (peer dep)
- **Zod 3+** (schema source)
- **react-hook-form** (peer dep)
- **Vite / Next.js / Remix** (tested)
- **Shadcn/ui themes** (drop-in)
- **Tailwind CSS** (styling)

## Features

- Zod schema → type-safe form in one line
- Built-in validation with error states
- Multi-step wizard mode
- Conditional fields (show/hide based on values)
- Custom component slots
- Shadcn/ui & Tailwind styled — easy to customize
- Dark mode support
- Full TypeScript types exported

## FAQ

### Is this compatible with react-hook-form?

Yes — it's built on top of react-hook-form and @hookform/resolvers. You get all the perf benefits and can drop into native RHF APIs when you need to.

### Can I use my own field components?

Yes. The `fieldComponents` prop maps field types (text, select, etc.) to your components, and `fieldOverrides` maps by field name for per-field swaps.

### What about CSS — does it bring its own?

It ships with Tailwind classes that match shadcn/ui. Override the classes via the `className` prop, or pass your own field components to fully take over.

### Can I use it in a commercial product?

Yes. The commercial license lets you use it in unlimited commercial and personal projects. You can't redistribute the source.

# React Data Grid

> [View this product on lib-pro](https://lib-pro-3f8437.gitlab.io/libs/react-data-grid) · The data table your framework should have shipped with.

**Outcome:** Cut your admin UI from 3 weeks to 3 days.

A polished, performant data table component. Sorting, filtering, pagination, inline editing, row selection, drag-to-reorder, export to CSV/Excel. Built on TanStack Table but saves you weeks of UI work.

**Price:** £15 — lifetime · **Category:** React Library · **Tech:** React 18+, TypeScript, TanStack Table, Tailwind CSS

| Metric | Value |
|--------|-------|
| Rows at 60fps | 100k+ |
| Time to first grid | 10 min |
| Export formats | 3 |

## Quick start

```bash
npm install react-data-grid @tanstack/react-table
```

- # Drop into your routes
- npm run dev
- # Try sort, filter, edit, export

## Code preview

```tsx
import { DataGrid, type Column } from 'react-data-grid'

interface User {
  id: string
  name: string
  email: string
  role: 'admin' | 'member'
  createdAt: string
}

const columns: Column<User>[] = [
  { id: 'name', header: 'Name', sortable: true, editable: true },
  { id: 'email', header: 'Email', sortable: true, editable: true },
  { id: 'role', header: 'Role', filter: true },
  { id: 'createdAt', header: 'Joined', type: 'date' },
]

export default function UsersTable({ rows }: { rows: User[] }) {
  return (
    <DataGrid
      columns={columns}
      rows={rows}
      onRowEdit={saveToServer}
      selectable
      exportable
    />
  )
}
```

## Use cases

### 1. Admin user management

List, search, filter, edit, bulk-delete, export — every admin action, in one grid, no glue code.

**Outcome:** The 'users' page takes an afternoon.

### 2. Customer-facing dashboards

Show the user their own data — transactions, projects, tickets — with inline edits and instant save.

**Outcome:** Dashboards that don't feel like spreadsheets.

### 3. Internal ops & finance

100k+ row datasets with server-side pagination, sort, and filter. Export to Excel for the CFO.

**Outcome:** The reports your CFO keeps asking for.

### 4. Data explorers

Type-safe column definitions, custom cell renderers, column groups. Build a Notion-grade data UI.

**Outcome:** Stop writing the same table component twice.

## Built for

- Frontend engineers building admin UI
- Full-stack devs who hate writing tables
- Teams standardising on TanStack Table
- Anyone shipping a CRUD app

## Highlights

### 100k rows, no jank

Row virtualization is on by default. Scroll a 100k-row table on a mid-range laptop and watch the frame rate hold.

### Click to edit anything

Cells are editable out of the box. Hook `onRowEdit` to your server and you've got a CRUD UI in five minutes.

### Export built in

CSV, Excel, PDF — all one click, all respecting the current sort & filter. The reports your PM keeps asking for are already there.

## What's in the box

- `DataGrid component` — the main grid
- `useDataGrid hook` — for custom UIs
- `Type-safe Column API` — full TypeScript inference
- `CSV / Excel / PDF export` — respects sort + filter
- `Inline edit handlers` — cell + row level
- `Server-side data adapter` — TanStack Query, SWR, or fetch
- `Column groups & pinning` — left/right, resizable
- `Full source + docs` — no obfuscation

## Works with

- **React 18+** (peer dep)
- **TanStack Table 8+** (peer dep)
- **TanStack Query** (server data)
- **SWR / fetch** (server data)
- **Vite / Next.js / Remix** (tested)
- **Tailwind CSS** (styling)

## Features

- Virtualized rows for 100k+ datasets
- Inline cell editing (click to edit)
- Column sorting, filtering, resizing, reordering
- Row selection (single & multi)
- Pagination & infinite scroll
- Export to CSV, Excel, PDF
- Dark mode & responsive
- Type-safe column definitions

## FAQ

### Does it work without TanStack Table?

No — TanStack Table is a peer dep. It's the best headless table library for React and it's tiny. We do the UI heavy-lifting on top of it.

### Can I bring my own server-side data fetching?

Yes. Pass a `fetcher` prop and the grid handles pagination, sort, and filter params for you. Bring TanStack Query, SWR, or fetch — your call.

### Does it support column groups and pinned columns?

Yes — `columnGroups`, `pinned: 'left' | 'right'`, and resizable handles are all first-class. The API matches the conventions of spreadsheet tools.

### What about Excel-style formulas?

No. This is a data grid, not a spreadsheet. If you need formula evaluation, use a dedicated library alongside.

# React AI Chat

> [View this product on lib-pro](https://lib-pro-3f8437.gitlab.io/libs/react-ai-chat) · Drop-in AI chat that looks like a product, not a demo.

**Outcome:** Ship a real AI chat feature in a single afternoon.

Streaming responses, tool calling visualization, file uploads, markdown rendering, conversation history — all as simple React components and hooks. Works with any LLM API.

**Price:** £25 — lifetime · **Category:** React Library · **Tech:** React 18+, TypeScript, Tailwind CSS, Vercel AI SDK compatible

| Metric | Value |
|--------|-------|
| Time to first message | 1 hour |
| Models supported | Any LLM |
| Built-in features | 8 |

## Quick start

```bash
npm install react-ai-chat ai
```

- # Wrap your app in <ChatProvider>
- # Point useChat at your /api/chat route
- # Done — works with OpenAI, Anthropic, local

## Code preview

```tsx
import { Chat, useChat } from 'react-ai-chat'

export default function ChatPanel() {
  const { messages, input, setInput, append, isLoading } = useChat({
    api: '/api/chat',          // your endpoint
    tools: [searchTool, dbTool], // function calling
  })

  return (
    <Chat
      messages={messages}
      input={input}
      onInput={setInput}
      onSend={(msg) => append({ role: 'user', content: msg })}
      isLoading={isLoading}
      enableFileUpload
    />
  )
}
```

## Use cases

### 1. In-app AI assistants

Help your users do things in your product by chat. Streaming, tool calls, file uploads — all the pieces.

**Outcome:** Ship a 'ChatGPT for your app' feature.

### 2. Customer support bots

Conversational UI over your docs, with tool calls to your API. Markdown and code blocks render correctly.

**Outcome:** Cut support load with a real product, not a bot.

### 3. Document Q&A

Drop in a PDF or a doc set, get back citations and answers. Custom tools for retrieval, formatting, follow-ups.

**Outcome:** Build a Perplexity clone over your data.

### 4. AI-powered tools

Build AI features that aren't pure chat. The hook is just state — wire it into your own UI however you want.

**Outcome:** AI as a feature, not as the whole product.

## Built for

- AI engineers shipping chat features
- Full-stack devs adding AI to existing apps
- Teams standardising on the Vercel AI SDK
- Indie hackers building AI tools

## Highlights

### Streaming you can feel

Token-by-token streaming with a typing indicator that doesn't lie. Markdown, code blocks, and tool calls render inline as they arrive.

### Tool calls, not magic

First-class support for function calling. Tools render as collapsible cards with their inputs and outputs visible — no hidden LLM behavior.

### Bring your own model

Works with the Vercel AI SDK. OpenAI, Anthropic, Mistral, OpenRouter, Ollama, your own fine-tune. Same hook, swap the endpoint.

## What's in the box

- `Chat component` — drop-in UI
- `useChat hook` — model-agnostic state
- `Streaming renderer` — token-by-token
- `Tool call cards` — input + output visible
- `File upload` — drag-and-drop
- `Markdown + code` — renders inline
- `Theme tokens` — light/dark/custom
- `Full source + docs` — no obfuscation

## Works with

- **React 18+** (peer dep)
- **Vercel AI SDK** (streaming + tools)
- **OpenAI / Anthropic** (any provider)
- **Mistral / Cohere / Ollama** (any provider)
- **OpenRouter** (multi-model)
- **Tailwind CSS** (styling)

## Features

- useChat hook — connect to any LLM API
- Streaming response rendering with typing indicators
- Tool call visualization & inline results
- Markdown & code block rendering
- File upload with drag-and-drop
- Conversation history management
- Customizable theme (light/dark)
- Built-in error handling & retry

## FAQ

### Do I need a backend?

Yes — you need an endpoint that calls your LLM. The library is the UI; the proxy is your call. We recommend the Vercel AI SDK's `streamText`.

### Does it work with non-OpenAI models?

Yes. Anything the Vercel AI SDK supports works: OpenAI, Anthropic, Mistral, Cohere, Ollama, OpenRouter. The chat UI doesn't care.

### Can I customize the theme completely?

Yes. Pass `theme` with token overrides, or replace individual components (message bubble, input, tool card) via the `slots` prop.

### How are conversations persisted?

It's your call. The hook takes a `messages` array you control. Save to localStorage, IndexedDB, your server, or a managed service — same code.

# AI Coding Playbook

> [View this product on lib-pro](https://lib-pro-3f8437.gitlab.io/libs/ai-coding-playbook) · The playbook we use to ship with AI agents.

**Outcome:** Turn a capable LLM into an orchestrator that ships.

5 battle-tested AI-agent skills — planner, sdd, worker, team, create — packaged as a methodology bundle. Includes drop-in adapters for Claude Code, Cursor, Cline, and Aider. Used to ship every library in this store.

**Price:** £10 — lifetime · **Category:** AI Skills Bundle · **Tech:** pi-agent, Claude Code, Cursor, Cline, Markdown

| Metric | Value |
|--------|-------|
| Skills | 5 |
| Adapters | 4 |
| Cost to author | £10 once |

## Quick start

```bash
tar -xzf ai-coding-playbook-0.1.0.tgz -C ./.pi
```

- # Skills live under .pi/skills/<name>/SKILL.md
- # Adapters under adapters/<tool>/
- # Pick your agent, drop in, restart session

## Code preview

```
# sdd — Spec-Driven Development

Four phases. Use them as vocabulary, not gates.

## explore
Read enough to know what you don't know.
Stop when you can name the unknowns.

## design
Name the shape before you write the code.
A short paragraph beats a long debate.

## apply
Make the change. Test it. Move on.
Don't revisit design mid-apply.

## verify
Did it actually do what you said?
If not, the design was wrong — go back.

A task can skip phases. A task can revisit a
phase. The phases are vocabulary, not gates —
but the order is the default.
```

## Use cases

### 1. Non-trivial feature work

Build a settings page, a billing flow, an admin tool. The planner writes the brief, the worker executes the easy parts, the team debates the hard parts.

**Outcome:** Stop getting half-thoughts back from the model.

### 2. Refactors & migrations

Move from Pages Router to App Router. Swap an auth lib. Rename a core type. Plan, phase, apply, verify.

**Outcome:** Big refactors that don't blow up the codebase.

### 3. Multi-repo orchestration

Update a shared package, regenerate consumers, run tests across repos. The team skill runs the cross-checks.

**Outcome:** One prompt, five repos updated in lockstep.

### 4. Building your own skills

The create skill teaches you when to capture a pattern as a reusable skill vs. a one-off command.

**Outcome:** A library of patterns that compounds over time.

## Built for

- Engineers using Claude Code or Cursor daily
- AI-heavy teams who want a shared vocabulary
- Solo founders shipping with AI agents
- Anyone tired of rewriting the same prompt

## Highlights

### Vocabulary, not a workflow

These skills name the moves: explore, design, apply, verify. Once you have the words, you stop arguing about steps and start shipping.

### Delegation as a first-class move

worker / team / planner — the playbook knows when to stop and dispatch. The model that's good at the wrong task isn't a model you use.

### Used to ship this store

Every product on this page — including the page you're reading — was built with these skills. Receipts not included; the site is.

## What's in the box

- `planner` — plan-then-execute discipline
- `sdd` — phase vocabulary + delegation
- `worker` — delegate to cheaper models
- `team` — multi-agent debate
- `create` — when to author a skill
- `Claude Code adapter` — drop-in
- `Cursor / Cline / Aider adapters` — drop-in
- `Worked example` — real usage

## Adapters included

These skills were authored for pi-agent, but we include drop-in adapters for the major AI coding tools.

| Tool | Adapter location | What you get |
|------|------------------|--------------|
| Claude Code | `adapters/claude-code/` | .claude/commands/*.md + CLAUDE.md fragments |
| Cursor | `adapters/cursor/` | .cursorrules rule sets |
| Cline / Continue | `adapters/cline/` | System-prompt rules |
| Aider / generic | `adapters/generic/` | INSTRUCTIONS.md snippets |

**Same playbook, different packaging.** The adapters translate the methodology into the format each tool expects. Install once, swap agents without re-learning the method.

## Features

- planner skill — plan-then-execute discipline with brief/context/next-action handoffs
- sdd skill — explore/design/apply/verify phase vocabulary + delegation contract
- worker skill — delegate to cheaper models with a live feedback loop
- team skill — multi-agent debate for hard decisions
- create skill — when to author a skill, agent, or command
- Drop-in adapters for Claude Code, Cursor, Cline, Aider
- Tested in production on this very storefront
- Personal-use commercial license

## FAQ

### What agents does this work with?

Claude Code, Cursor, Cline, and Aider ship with first-class adapters. The skills are plain Markdown so any agent that reads a system-prompt file can use them.

### Is this just prompts?

No. Each skill is a SKILL.md with a trigger pattern, a methodology, and a delegation contract. They're designed to be loaded by the agent at the right moment, not pasted in.

### Do I need a specific model?

No. The skills are model-agnostic. Pair the planner/team skills with a strong model and the worker skill with a cheap one — that's the whole point.

### What's the difference vs an agent template?

Templates tell the agent what to do. Skills teach the agent a discipline it can apply to new problems. You don't outgrow a skill.

# Job Search System

> [View this product on lib-pro](https://lib-pro-3f8437.gitlab.io/libs/job-search-system) · The methodology behind 70+ tailored applications.

**Outcome:** A job search that runs on a system, not a feeling.

AI-assisted job search system. The persona pattern, Fit Check Method, Cover Letter Rules, Pipeline framework, and templates that take you from discovery to signed offer. Extracted from a real search.

**Price:** £15 — lifetime · **Category:** Methodology Bundle · **Tech:** pi-agent, Claude Code, Cursor, Cline, Markdown

| Metric | Value |
|--------|-------|
| Applications sent | 70+ |
| Real search used in | 1 |
| Offers | Multiple |

## Quick start

```bash
tar -xzf job-search-system-0.1.0.tgz -C ./.pi
```

- # Fill in profile.md and comp-notice.md
- # Use the cover-letter command on your next JD
- # Use fit-check before every application

## Code preview

```
# fit-check — The Fit Check Method

Don't apply to a job. Run a Fit Check.

## Inputs
- The JD (pasted, or URL + scraped)
- Your profile (profile.md)
- Your comp & notice constraints

## Output
A 0–100 fit score with required reading.

## Rule
If the score is < 70, write down the
reason you're applying anyway.
If the reason is "I need a job," don't apply.

## The four questions
1. Does the role match what I said I want?
2. Does the comp beat what I'd accept?
3. Does the company pass the 1-year test?
4. Would I take this if I had two offers?
```

## Use cases

### 1. Senior engineering job search

Staff, principal, or EM roles. Use the persona pattern to roleplay the hiring manager, fit-check every JD.

**Outcome:** Cut the noise, focus on roles that match.

### 2. AI / ML roles

AI engineer, ML engineer, applied research. Templates tuned for AI domain — paper writing, evals, infra.

**Outcome:** AI roles need tailored positioning. This is it.

### 3. Design engineering / DX

The intersection of design and code. Profile template includes the 'designs what they build' positioning.

**Outcome:** Stop getting filtered by both recruiters.

### 4. Career pivots

Use the persona pattern to reframe your experience for a new domain. fit-check catches the gaps.

**Outcome:** Pivots that get callbacks, not crickets.

## Built for

- Senior engineers in active search
- AI/ML specialists targeting specific roles
- Design engineers carving out a niche
- Career switchers who need a system, not motivation

## Highlights

### The AI Hiring Manager persona

Stop asking the model to be supportive. Make it the hiring manager who'd reject you. The output gets useful in a hurry.

### Fit Check, not spray-and-pray

Every JD gets a 0–100 score with the reason you'd apply anyway. If the answer is 'I need a job,' you don't apply.

### Tailored at scale

Cover letters that sound like you, not like a template. The methodology takes 70+ tailored applications off the 'impossible' list.

## What's in the box

- `career-strategy` — persona + pipeline
- `fit-check` — 0-100 scoring
- `job-search` — source discovery
- `job-apply` — tailored submissions
- `interview-prep` — operational answers
- `4 templates` — profile, comp, AI targets, cover
- `4 adapters` — Claude Code, Cursor, Cline, Aider
- `Worked example` — real AI Eng Leader search

## Adapters included

These skills were authored for pi-agent, but we include drop-in adapters for the major AI coding tools.

| Tool | Adapter location | What you get |
|------|------------------|--------------|
| Claude Code | `adapters/claude-code/` | .claude/commands/*.md + CLAUDE.md fragments |
| Cursor | `adapters/cursor/` | .cursorrules rule sets |
| Cline / Continue | `adapters/cline/` | System-prompt rules |
| Aider / generic | `adapters/generic/` | INSTRUCTIONS.md snippets |

**Same playbook, different packaging.** The adapters translate the methodology into the format each tool expects. Install once, swap agents without re-learning the method.

## Features

- Templates for profile, comp/notice, AI target lists, cover letter
- Adapters for Claude Code, Cursor, Cline, Aider
- Worked example fit check + 5 reusable command files

## FAQ

### Is this resume advice?

No. It's a system for running a job search where the AI is an operating partner, not a copywriter. The cover letters are one output among many.

### Does it work for senior roles?

Yes. It was extracted from a real mid-senior search. The Fit Check, persona pattern, and pipeline framework matter more as the stakes rise.

### What if I'm not in tech?

Most of it transfers. The persona pattern and Fit Check work anywhere. The JD-sourcing skills lean on tech boards but are pluggable.

### Is it really from a real search?

Yes. The fit-check example in the package is from a real AI Engineering Leader search. 70+ applications, multiple offers, one signed.

# bb-methodology — Workflow + Mindset

The master orchestrator. Loads first, routes to everything else.

## Daily Discipline: Define, Select, Execute

Before touching any tool:

1. **Define**: "Today I target [feature/domain] to achieve [CIA impact]"
2. **Select**: Choose 1-2 vuln classes (IDOR, Race Condition, etc.)
3. **Execute**: Focus ONLY on selected techniques. No wandering.

## 5 Ultimate Goals (Pick One Per Session)

1. **Confidentiality** — steal data the attacker shouldn't see
2. **Integrity** — modify data the attacker shouldn't change
3. **Availability** — disrupt service (app-level DoS only)
4. **Account Takeover** — control another user's account
5. **RCE** — execute commands on the server

## The 5-Phase Non-Linear Flow

Every hunter has the same five phases. Top 1% run them fast and bounce between them as the data flows.

```

## Use cases

### 1. Your first bug bounty submission

Signed up for HackerOne, stared at the target, didn't know where to start. The bb-methodology skill gives you the discipline.

**Outcome:** First report submitted within 2 weeks.

### 2. Scaling from 1 to 5 programs

Currently hunting one program at a time. The pipeline + ops skill lets you run parallel recon across multiple targets.

**Outcome:** 5x more reconnaissance, same time investment.

### 3. Client security audits

Selling pentest services. The methodology + reporting framework gives you repeatable, defensible audit results.

**Outcome:** Reusable audit playbooks you can run junior consultants through.

### 4. Web3-specific hunting

Solidity + smart contract vulnerabilities are a different game. The web3-audit skill covers reentrancy, access control, MEV.

**Outcome:** A new revenue stream in a less-saturated market.

## Built for

- New hunters who signed up but don't know where to start
- Part-time hunters who want to ship more reports without burning out
- Security consultants who want reusable methodology
- AI coders who want the methodology baked into their workflow
- Solo founders looking for a high-leverage side income

## Highlights

### Methodology, not a workflow

These skills name the moves: explore, design, apply, verify. Once you have the words, you stop arguing about steps and start shipping.

### Top 1% thinking patterns

The persona pattern and anomaly-detection rubric are what separates a scanner from a hunter. The skills teach both.

### Real submissions, real payouts

Worked example: a P1 account-takeover via CORS misconfiguration, triaged in 4 hours, paid $5,000 in 5 days. Redacted, but the methodology is real.

## What's in the box

- `21 skills` — 281 KB of methodology
- `Recon pipeline` — subfinder → httpx → nuclei → triage
- `SQLite schema` — subdomains, responses, findings, triage, reports
- `LLM provider config` — OpenAI, Anthropic, local — $0–$50/mo
- `Docker stack` — swarm-deployable
- `Real worked example` — P1 account takeover, redacted
- `Claude Code adapter` — .claude/commands + CLAUDE.md
- `Cursor / Cline / Aider adapters` — drop-in rules

## Adapters included

These skills were authored for pi-agent, but we include drop-in adapters for the major AI coding tools.

| Tool | Adapter location | What you get |
|------|------------------|--------------|
| pi-agent | `adapters/pi-agent/` | SKILL.md files for the host's ~/.pi/agent/skills/ |
| Claude Code | `adapters/claude-code/` | CLAUDE.md + slash commands |
| Cursor | `adapters/cursor/` | .cursorrules rule sets |
| Cline / Continue | `adapters/cline/` | System-prompt rules |
| Aider / generic | `adapters/generic/` | INSTRUCTIONS.md snippets |

**Same playbook, different packaging.** The adapters translate the methodology into the format each tool expects. Install once, swap agents without re-learning the method.

## Features

- bb-methodology skill — master orchestrator + 5-phase non-linear workflow
- bug-bounty skill — program navigation, scope rules, payment tiers
- web2-recon + web2-vuln-classes — 24 KB of hunt-tested recon methodology
- triage-validation skill — eliminate false positives before reporting
- report-writing skill — templates that get accepted on first submission
- threat-model + credential-attack + coverage — advanced playbooks
- 3 platform-specific skills — HackerOne, Intigriti, YesWeHack rules
- Working recon pipeline (subfinder → httpx → nuclei → LLM triage → report)
- Sample target walkthrough with a redacted P1 report
- Adapters for Claude Code, Cursor, Cline, Aider
- Web3 + meme-coin audit methodologies (lucrative niches)
- $0–$50/mo operating budget — small LLM for triage, free static recon

## FAQ

### Is this for beginner bug bounty hunters?

It's for anyone who has signed up for a program and doesn't know where to start. The methodology assumes you understand HTTP, basic dev tools, and reading code. It does NOT assume you've ever submitted a report.

### Will the methodology work for HackerOne / Intigriti / YesWeHack?

Yes. Three platform-specific skills ship (HackerOne, Intigriti, YesWeHack) covering scope rules, submission patterns, and response-time expectations. The core methodology is platform-agnostic.

### What's the operating cost?

$0–$50/month depending on how many targets you run. Static recon (subfinder, httpx, nuclei) is free. The LLM triage step uses a small model on tight budget caps. Most hunters run at $0–$10/mo by using a local 4B model.

### Does this work for Web3 / smart contract audits?

Yes. The web3-audit skill covers reentrancy, access control, MEV, and the unique tooling of smart contract hunting. The meme-coin-audit skill digs into the very specific (and lucrative) world of token launches.

### Do I need to run the pipeline to use the skills?

No. The skills are the methodology. The pipeline is a tool that uses the methodology. You can read the skills yourself, run recon by hand, or load them into an AI coder for guidance.

### What does the worked example show?

A redacted walkthrough of a real engagement — the recon run, the triage findings, the actual report that was submitted. The program name is anonymised but the methodology, evidence, and impact are genuine.

# Evals Studio

> [View this product on lib-pro](https://lib-pro-3f8437.gitlab.io/libs/evals-studio) · The eval pipeline senior AI engineering leaders are expected to run.

**Outcome:** A production-grade eval pipeline that turns 'I haven't built an eval pipeline' into 'yes — here it is.'

A production-grade evaluation pipeline for agentic AI systems. M1 code-complete: real agent runtime with tool calls + structured outputs + access controls, deterministic scorers (schema, citations, access), a runner with regression detection, Fastify service, SQLite state store, and 3 starter golden-set cases. The architecture is shaped to support M2–M6 (golden set expansion, LLM-as-judge, regression tracking, feedback loop) without rewrites.

**Price:** £40 — lifetime · **Category:** Reference Implementation · **Tech:** TypeScript, Node 20, Fastify, OpenAI SDK, better-sqlite3, Zod, Markdown

| Metric | Value |
|--------|-------|
| Milestone | M1 |
| Starter cases | 3 |
| Deterministic scorers | 5+ |
| Roadmap | M2–M6 |

## Quick start

```bash
tar -xzf evals-studio-0.2.0.tgz && cd evals-studio-0.2.0 && npm install
```

- # Install
- npm install
- # Smoke test (no LLM needed)
- npm test
- # Run the M1 golden set
- npm run eval
- # Or start the Fastify service
- npm start

## Code preview

```tsx
/**
 * Deterministic scorers. Pure functions — given a case + output,
 * the score is fully traceable. The rationale string explains exactly
 * why a case failed, which makes a "failed" debuggable in 30 seconds.
 *
 * The pattern: deterministic checks for shape, citations, and access.
 * LLM-as-judge for quality (in M3). This pack ships the deterministic
 * half, which is the part most teams skip — and that's why their
 * pipelines are untrustworthy.
 */

import type { Scorer, ScoreRecord, ScorerContext } from "./types.js";
import type { ResearchOutput } from "../agent/types.js";

const passed = (
  scorer: string,
  score: number,
  reason: string
): ScoreRecord => ({ scorer, passed: score === 1, score, reason });

/**
 * Structural validity: the output matches the ResearchOutput schema and
 * (in answer mode) has at least one citation; (in refuse mode) has
 * refused=true with a non-empty reason.
 */
export const schemaScorer: Scorer = ({ case: c, output }): ScoreRecord => {
  if (typeof output.answer !== "string") {
    return passed("schema", 0, "answer must be a string");
  }
  if (output.refused) {
    if (typeof output.refusal_reason !== "string" || output.refusal_reason.length === 0) {
      return passed("schema", 0, "refusal_reason required when refused=true");
    }
    return passed("schema", 1, "refusal shape ok");
  }
  // ... (continues with citation checks, access checks, etc.)
};

```

## Use cases

### 1. Closing the AI eval gap

On a senior AI engineering interview track. Hiring managers ask 'have you built an eval pipeline?' This is the answer.

**Outcome:** From 'I'm learning' to 'yes — here it is.'

### 2. Production eval for your own AI team

Building an AI agent product. Need to know if a model upgrade actually improves things or just shuffles failures. Drop your agent in, run the golden set.

**Outcome:** Catch regressions before users do.

### 3. Differentiator for client LLM work

Selling AI consulting. Most consultants ship prompts; you ship a pipeline that proves the outputs are good. The architecture is the same shape Big Tech uses.

**Outcome:** Premium pricing because you can defend the work.

### 4. Calibrate an LLM-as-judge

Need a cheap, fast way to grade 1000s of outputs. Build it on this framework — the deterministic scorers are your ground truth, the LLM judge is calibrated against them.

**Outcome:** Automated grading that doesn't lie.

## Built for

- Senior AI engineering leaders preparing for system-design interviews
- AI engineering managers building eval pipelines for their team
- Consultants selling LLM work who need defensible quality measurement
- AI product teams who want to catch quality regressions before users
- Researchers building reproducible eval harnesses for papers

## Highlights

### Architecture, not vendor lock-in

The eval harness is generic. The agent (`src/agent/agent.ts`) is a swap-in module. Replace your agent — same pipeline, same scorers, same UI.

### Deterministic, not vibe-based

Every scorer is a pure function with a rationale string. Failed cases are debuggable in 30 seconds — 'this failed because citation src-003 was missing.'

### Regression-aware, not one-shot

Every run is persisted to SQLite. The runner compares to the previous baseline. Drift between model upgrades is loud, not silent.

## What's in the box

- `Agent runtime` — replace with your own
- `Deterministic scorers` — schema, citations, access
- `Runner + regression detection` — vs prior baseline
- `Fastify service` — POST /runs, GET /runs/:id
- `SQLite state store` — single file, no infra
- `3 starter golden cases` — happy path + 2 violations
- `Pre-built dist/` — runs without a build step
- `Architecture docs` — M2–M6 roadmap built in

## Adapters included

These skills were authored for pi-agent, but we include drop-in adapters for the major AI coding tools.

| Tool | Adapter location | What you get |
|------|------------------|--------------|
| pi-agent | `adapters/pi-agent/` | SKILL.md drop-in |
| Claude Code | `adapters/claude-code/` | CLAUDE.md fragments |
| Cline / Continue | `adapters/cline/` | System-prompt rules |
| Aider / generic | `adapters/generic/` | INSTRUCTIONS.md snippets |

**Same playbook, different packaging.** The adapters translate the methodology into the format each tool expects. Install once, swap agents without re-learning the method.

## Features

- Agent runtime with real tool calls + structured outputs + access controls
- Deterministic scorers (schema, citations, access controls) — pure functions, traceable
- Runner with run history + regression detection against prior baseline
- SQLite persistence (single file, no infra) — better-sqlite3
- Fastify API service — POST /runs, GET /runs/:id, GET /regressions
- CLI for running the golden set from your terminal
- 3 starter golden-set cases (happy path, access violation, required citation)
- Pre-built dist/ — runs without a build step
- Architecture docs — shaped to support M2–M6 without rewrites
- Adapters for Claude Code, Cursor, Cline, Aider
- TypeScript on Node 20, Fastify 4, OpenAI SDK
- Open-source upgrade path (M1 is MIT upstream, this is a curated package)

## FAQ

### Is this a complete eval pipeline or just a foundation?

It's M1 code-complete — a working pipeline, scorer framework, runner, Fastify API, and 3 starter cases. The full 6-milestone vision includes golden-set expansion (M2), LLM-as-judge with calibration (M3), regression tracking (M4), feedback loop (M5), and an interview artefact (M6). The architecture is shaped to support all of them without rewrites.

### How do I use this with my own agent?

Edit `src/agent/agent.ts` to wire your LLM tool calling + structured output. The `AgentRuntimeDeps` interface is the contract — implement `dispatchToolCall` and pass your tool schemas. The runner drives the loop; the scorers evaluate the output.

### What LLM does it use?

The agent runtime uses the OpenAI SDK, which works with any OpenAI-compatible endpoint. Default: local `http://ai_gpu:88/v1` (Qwen3.6-35B-A3B). Configure via `OPENAI_BASE_URL` and `OPENAI_API_KEY` env vars.

### Why SQLite? Postgres seems more 'production'.

SQLite is a single file. No infra. No auth. No replicas. No migrations. For an eval pipeline that runs a few hundred times a day, it's the right tool. The schema is portable — when you outgrow SQLite, `pg_dump` in Postgres and update the connection layer. The architecture is the value.

### What's the operating cost?

Static cost: $0. The LLM call is the only per-run cost. With a local Qwen 3 8B model, that's free. With GPT-4o-mini, roughly $0.01 per case. With GPT-4o, roughly $0.10 per case. The pipeline itself is zero.

### How is this different from Langfuse / LangSmith / Helicone?

Those are observability + production tracing tools. This is an eval pipeline. Different concern. You can run this pack alongside Langfuse — the eval pipeline uses this pack's golden set + scorers; Langfuse watches production traffic. They complement each other.

### Why is the upstream MIT but this pack is commercial?

The upstream `evals-studio` repo is a public artefact — the whole point is showing what's possible. This pack is a curated, packaged version with adapters, examples, and a clear path from M1 to M6. The upstream code is the architecture; the pack is the deliverable.

# Agent Reliability Playbook

> [View this product on lib-pro](https://lib-pro-3f8437.gitlab.io/libs/agent-reliability-playbook) · Ship agents that work in production. The 7-layer reliability stack.

**Outcome:** Ship AI agents that work in production, not just on demos.

The 7-layer reliability stack for shipping AI agents that work in production. 7 skills covering orchestration, tool design, state management, error recovery, observability, stopping conditions, and the catalog of 15 anti-patterns. Adapters for pi-agent, Claude Code, Cursor, Cline, and any tool that reads a system-prompt file. The same discipline that prevents the $400 OpenAI bill from a runaway loop, the email-to-the-wrong-recipient, and the agent that 'works on demos but fails with users'.

**Price:** £45 — lifetime · **Category:** Production AI Skills · **Tech:** pi-agent, Claude Code, Cursor, Cline, Markdown

| Metric | Value |
|--------|-------|
| Skills | 7 |
| Anti-patterns | 15 |
| Tool adapters | 5 |
| Pre-launch items | 12 |

## Quick start

```bash
tar -xzf agent-reliability-playbook-0.1.0.tgz && cd agent-reliability-playbook-0.1.0
```

# agent-reliability — Master Orchestrator

You have an LLM agent that demos beautifully. Three prompts in, it nails the task. Six prompts in, it hallucinates a tool call. Ten prompts in, it loops until your OpenAI bill explodes.

This is the master playbook. It teaches the 7-layer reliability stack every production agent needs. It routes to six specialist skills based on which layer you're working on.

## The 7-Layer Reliability Stack

Every production agent needs all seven layers. Skip one and the agent breaks in production.

┌─────────────────────────────────────────────────┐
│ 7. Anti-Patterns Catalog   → what NOT to do    │
├─────────────────────────────────────────────────┤
│ 6. Stopping Conditions     → when to stop       │
├─────────────────────────────────────────────────┤
│ 5. Observability           → what's happening   │
├─────────────────────────────────────────────────┤
│ 4. Error Recovery          → what fails         │
├─────────────────────────────────────────────────┤
│ 3. Agent State             → what to remember   │
├─────────────────────────────────────────────────┤
│ 2. Tool Design             → what the agent     │
│                              can call           │
├─────────────────────────────────────────────────┤
│ 1. Orchestration           → how it decides     │
└─────────────────────────────────────────────────┘

The patterns: walk top-down during debug (most bugs are familiar). Walk bottom-up during build (orchestration → tool design → state → error recovery → observability → stopping → anti-patterns review).

## Routing Table

| You see this in prod | Load this skill |
|---|---|
| Agent calls the wrong tool | tool-design |
| Agent loops forever burning tokens | stopping-conditions |
| Agent fails to recover from a tool error | error-recovery |
| Agent loses context after 20 turns | agent-state |
| Agent produces output but you can't debug | agent-observability |
| Familiar failure mode | anti-patterns |

## Pre-Launch Checklist (Bold = non-negotiable)

- Orchestration chosen deliberately
- Tool definitions have descriptions the model can read
- Tool calls validated before execution
- State management strategy defined
- Error recovery policy for every tool call
- Observability is logging
- Stopping conditions in code
- Eval set covers happy path + 3 adversarial cases
- Cost estimate per session
- Latency budget per turn
- Rollback plan
- 5 prod transcripts reviewed end-to-end
```

## Use cases

### 1. Your first production AI agent

You've built an agent prototype. It works on 3 test cases. Now you need to ship it to real users without breaking everything. The 7 layers are the discipline.

**Outcome:** Ship with confidence, not crossed fingers.

### 2. Debugging a familiar failure

Agent booked 38 hotel rooms. Or sent an email to the wrong person. Or forgot the original goal after 20 turns. The anti-patterns skill is the catalog.

**Outcome:** Identify the failure in 5 minutes, not 5 days.

### 3. Training your team on agent design

New engineers joining your AI team. They need to learn the discipline before they ship. The playbook is the onboarding curriculum.

**Outcome:** Faster onboarding, fewer production incidents.

### 4. Pre-launch review for AI features

Every AI feature ships through a review checklist. The pack is the review checklist — 12 items for the orchestrator, 15 for the anti-patterns.

**Outcome:** Catch the obvious mistakes before users do.

## Built for

- AI engineers shipping their first production agent
- Senior engineers who have shipped agents and learned the hard way
- AI engineering managers who need a team-wide discipline
- Indie hackers building AI products who can't afford a production incident
- Consultants selling AI agent work who need defensible quality

## Highlights

### 7 layers, one pack

Orchestration, tool design, state, error recovery, observability, stopping, anti-patterns. Skip one and the agent breaks. The pack teaches all 7.

### Prevents the $400 bill

The runaway loop anti-pattern (AP-01) caught every AI builder. The pack teaches the cost caps, loop detection, and confirmation gates that stop it before users get charged.

### Discipline in code, not prompts

Every 'be efficient' / 'stop when done' / 'be safe' instruction in a prompt is a bug. The pack teaches the code-level patterns that actually enforce the discipline.

## What's in the box

- `7 skills` — one per reliability layer
- `5 tool adapters` — pi-agent, Claude Code, Cursor, Cline, generic
- `2 worked examples` — tool rewrite + runaway loop fix
- `Pre-launch checklist` — 12 items
- `Anti-patterns catalog` — 15 failure modes
- `Cost math per model tier` — know your bounds
- `Routing table` — which skill to load when
- `Decision trees` — workflow vs. agent vs. hybrid

## Adapters included

These skills were authored for pi-agent, but we include drop-in adapters for the major AI coding tools.

| Tool | Adapter location | What you get |
|------|------------------|--------------|
| pi-agent | `adapters/pi-agent/` | SKILL.md drop-in |
| Claude Code | `adapters/claude-code/` | .claude/commands/*.md + CLAUDE.md fragments |
| Cursor | `adapters/cursor/` | .cursorrules rule sets |
| Cline / Continue | `adapters/cline/` | System-prompt rules |
| Aider / generic | `adapters/generic/` | INSTRUCTIONS.md snippets |

**Same playbook, different packaging.** The adapters translate the methodology into the format each tool expects. Install once, swap agents without re-learning the method.

## Features

- agent-reliability skill — master orchestrator + 7-layer reliability stack + pre-launch checklist
- tool-design skill — 8 rules for the agent-computer interface (Anthropic's ACI discipline)
- agent-state skill — context budget, message trim, checkpoint/restore
- error-recovery skill — retry strategies, structured errors, idempotency keys
- agent-observability skill — structured logging, traces, replay, vendor comparison
- stopping-conditions skill — 8 hard caps + loop detection + confirmation gates
- anti-patterns skill — catalog of 15 failure modes with symptoms, cause, fix, detection
- 5 tool adapters — pi-agent, Claude Code, Cursor, Cline, generic
- 2 worked examples — tool rewrite (40%→4% wrong calls), runaway loop fix ($44→$0.35)
- Pre-launch checklist — 12 items, all checked
- Cost math per model tier — know your bounds before shipping
- Routing table — agent loads the right specialist skill for the right problem

## FAQ

### Is this just prompt engineering with extra steps?

No. The pack teaches the discipline of putting it in code, not the prompt. MAX_ITERATIONS in code, not 'be efficient'. Confirmation gates in code, not 'ask before sending'. Idempotency keys in code, not 'be careful with retries'. The patterns are about what your agent code does, not what your agent prompt says.

### Does it work with my framework? (LangChain / LangGraph / CrewAI / raw OpenAI SDK)

Yes. The pack is methodology, not framework code. It works with LangChain, LangGraph, CrewAI, Vellum, raw OpenAI SDK, or anything else. The skills are pure markdown — they teach patterns you apply to whatever you're building on.

### What's the difference vs. LangSmith / Langfuse / Helicone?

Those are observability tools — they help you see what's happening. This pack is the methodology — what to log, what to do when errors happen, when to stop. You can use the pack + an observability vendor together. The pack tells you what to instrument; the vendor helps you view it.

### Will this prevent all my agent bugs?

No. The 7 layers address the most common, expensive, familiar failure modes. They don't address novel bugs, model-specific quirks, or genuinely new patterns. The pack is discipline, not magic. But it catches 80%+ of the bugs that hit production agents.

### I'm building a single-prompt LLM feature, not an agent. Do I need this?

Probably not. The 7 layers are for agents (multi-step, tool-using, stateful). Single-prompt features have their own discipline (prompt engineering, eval, cost control), which is a different skill set. The pack is honest about this — if you don't have tools or state, you don't need the 7 layers.

# LLM Evaluation Engineering

> [View this product on lib-pro](https://lib-pro-3f8437.gitlab.io/libs/llm-evaluation) · The methodology that catches regressions before users do.

**Outcome:** Ship LLM features with quantitative feedback, not vibes.

5 skills for shipping LLM features with quantitative feedback loops: the eval funnel (deterministic → LLM-as-judge → human), golden set construction, scorer patterns, calibration, and eval-driven development. The same methodology Hamel Husain teaches in his $4,200 Maven course — packaged as a SKILL.md bundle you can apply to any eval system (Braintrust, LangSmith, Arize, Helicone, or your own).

**Price:** £40 — lifetime · **Category:** Production AI Skills · **Tech:** pi-agent, Claude Code, Cursor, Cline, Markdown, Eval vendors (vendor-agnostic)

| Metric | Value |
|--------|-------|
| Skills | 5 |
| Adapters | 5 |
| Worked examples | 2 |

## Quick start

```bash
tar -xzf llm-evaluation-0.1.0.tgz && cd llm-evaluation-0.1.0
```

- # Pick your agent host

# llm-evaluation — The Eval Funnel

All you get from using prefab evals is you don't know what they actually do.
— Hamel Husain

The eval funnel:

1. **Deterministic** (cheap, fast, reliable) — schema, regex, exact-match, citation-presence. The workhorses.
2. **LLM-as-judge** (expensive, slower, needs calibration) — quality, nuance, open-ended answers. Calibrate against human ground truth.
3. **Human review** (slowest, most expensive, ground truth) — spot-check, edge cases, new failure modes.

Every eval system should walk the funnel. Most ship the wrong way (LLM-as-judge first, no calibration, no ground truth).

## The 5 Skills

| Skill | What it teaches |
|---|---|
| llm-evaluation | The funnel, when to use what, the eval mindset |
| eval-design | What to measure, how to write criteria, golden sets |
| deterministic-scorers | Schema checks, regex, exact-match, citation-presence |
| llm-as-judge | When LLM judges work, calibration, prompt design, pitfalls |
| eval-driven-dev | Eval-first PRs, baseline tracking, regression detection |

## The Core Idea

> Build evals from real failures, not imagined ones. Run evals on every change. Compare to the prior baseline.
```

## Use cases

### 1. You're shipping an LLM feature

You added a new prompt. You want to know if quality went up or down. No eval system, just vibes and a few manual checks.

**Outcome:** Build a 20-case golden set, run it on every PR, never ship a regression again.

### 2. You're evaluating a new model

GPT-5 just dropped. You want to know if it's better than Sonnet for your use case. The vendor says yes. Your gut says maybe.

**Outcome:** Run your golden set on both models. See the numbers. Decide with data, not vibes.

### 3. You're scaling AI features

Three teams, six features, dozens of prompts. You can't manually review every change. Quality is drifting.

**Outcome:** Standardize on the eval funnel. Every team runs the same workflow. Quality becomes measurable.

## Built for

- AI engineers shipping their first LLM feature
- AI engineering managers who need a team-wide eval standard
- Senior engineers who want to defend AI work with data
- Indie hackers shipping AI products who can't afford a quality incident

## Highlights

### The eval funnel

Deterministic first (cheap, fast, reliable). LLM-as-judge second (expensive, needs calibration). Human review last (ground truth). Every eval system should walk the funnel.

### Golden sets from real failures

The best golden sets are built from real prod failures, not imagined test cases. The pack teaches how to harvest failures into your eval set.

### Eval-first PRs

Run evals before merging. Compare to the prior baseline. Catch regressions before they reach users. The workflow, not the tool.

## What's in the box

- `5 skills` — eval funnel, design, scorers, judge, workflow
- `5 tool adapters` — pi-agent, Claude Code, Cursor, Cline, generic
- `2 worked examples` — eval design + regression detection
- `Methodology` — vendor-agnostic
- `Calibration patterns` — for LLM-as-judge
- `Golden set construction` — from real failures

## Adapters included

These skills were authored for pi-agent, but we include drop-in adapters for the major AI coding tools.

| Tool | Adapter location | What you get |
|------|------------------|--------------|
| pi-agent | `adapters/pi-agent/` | SKILL.md drop-in |
| Claude Code | `adapters/claude-code/` | .claude/commands/*.md + CLAUDE.md |
| Cursor | `adapters/cursor/` | .cursorrules rule sets |
| Cline / Continue | `adapters/cline/` | System-prompt rules |
| Aider / generic | `adapters/generic/` | INSTRUCTIONS.md snippets |

**Same playbook, different packaging.** The adapters translate the methodology into the format each tool expects. Install once, swap agents without re-learning the method.

## Features

- llm-evaluation skill — master orchestrator + the eval funnel
- eval-design skill — what to measure, criteria writing, golden sets from real failures
- deterministic-scorers skill — schema checks, regex, exact-match, citation-presence
- llm-as-judge skill — when LLM judges work, calibration, prompt design, bias mitigation
- eval-driven-dev skill — eval-first PRs, baseline tracking, regression detection
- 5 tool adapters — pi-agent, Claude Code, Cursor, Cline, generic
- 2 worked examples — eval design + regression detection
- Methodology, not vendor lock-in — works with Braintrust, LangSmith, Arize, Helicone, or your own

## FAQ

### Is this a Braintrust / LangSmith / Helicone replacement?

No. The pack is methodology — what to measure, how to design evals, how to detect regressions. The vendors are infrastructure — they run the evals. Use both: this pack for the playbook, your vendor for execution.

### How is this different from Hamel Husain's Maven course?

Hamel's course is the gold standard. This pack distills the same methodology into a SKILL.md bundle you can drop into your agent. The course is 6 weeks of video; the pack is the same playbook, condensed, agent-loadable.

### I don't have any evals yet. Where do I start?

Start with eval-design. It teaches you to write criteria, build a golden set from real failures, and pick the right granularity. From there, deterministic-scorers first (cheap), LLM-as-judge second (calibrate against human).

# RAG Engineering Playbook

> [View this product on lib-pro](https://lib-pro-3f8437.gitlab.io/libs/rag-engineering) · Stop building naive RAG. Start building RAG that doesn't hallucinate.

**Outcome:** Ship a RAG pipeline that doesn't hallucinate.

5 skills for shipping RAG pipelines that work in production: the 5-stage RAG pipeline (parse → chunk → embed → retrieve → generate), chunking strategies, retrieval patterns (vector + hybrid + rerankers), evaluation metrics, and advanced patterns (agentic, graph, multimodal). Methodology, not framework — works with LangChain, LlamaIndex, Haystack, or custom code.

**Price:** £35 — lifetime · **Category:** Production AI Skills · **Tech:** pi-agent, Claude Code, Cursor, Cline, Markdown, Vector DBs (Pinecone, Weaviate, Qdrant, pgvector — vendor-agnostic)

| Metric | Value |
|--------|-------|
| Skills | 5 |
| Stages covered | 5 |
| Patterns documented | 15+ |

## Quick start

```bash
tar -xzf rag-engineering-0.1.0.tgz && cd rag-engineering-0.1.0

# rag-engineering — The RAG Decision Tree

Naive RAG fails in production. The fix is not "better embeddings" — it's a deliberate architecture.

## When to use RAG

- Your data is too large for the context window → RAG
- Your data changes frequently → RAG (vs fine-tuning)
- You need citations in answers → RAG
- Your data is highly structured → maybe graph RAG

When NOT to use RAG:
- The answer fits in the prompt → just put it in the prompt
- You can fit the data in context → just use long-context
- You need the model to *learn* patterns → fine-tuning

## The 5-Stage Pipeline

1. **Parse** — extract text from PDFs, docs, code, tables
2. **Chunk** — split into retrieval units (multiple strategies)
3. **Embed** — turn chunks into vectors
4. **Retrieve** — find relevant chunks (vector + hybrid + rerankers)
5. **Generate** — prompt the LLM with retrieved context

Each stage has 2-3 patterns. The architecture is your choice of patterns. The pack teaches the tradeoffs.
```

## Use cases

### 1. Your first RAG pipeline

You want to ground an LLM in your company's docs. You picked a vector DB, embedded naively, and the answers are 'okay-ish' but full of hallucinations.

**Outcome:** Walk the 5-stage pipeline, pick the right patterns for your data, ship a RAG that doesn't hallucinate.

### 2. Your RAG is good, not great

Your RAG works for some queries. Others miss. You don't know which patterns to change. Tuning is hit-or-miss.

**Outcome:** Add a golden set. Measure retrieval quality. Find the weak stage. Apply the right pattern. Iteratively improve.

### 3. Naive RAG isn't enough

Single-step retrieval misses multi-hop questions. Your users need answers that combine 3+ documents. Time for advanced patterns.

**Outcome:** Move to agentic RAG (multi-step retrieval) or graph RAG (knowledge graph). The advanced-rag skill teaches when each is worth the complexity.

## Built for

- AI engineers building their first RAG pipeline
- AI builders with naive RAG that hallucinates
- Senior engineers evaluating vector DBs and chunking strategies
- AI product teams who need to defend retrieval quality with data

## Highlights

### 5-stage pipeline, 2-3 patterns per stage

Parse → chunk → embed → retrieve → generate. Each stage has patterns with explicit tradeoffs. The architecture is your choice. The pack teaches the choices.

### Retrieval that actually retrieves

Vector alone misses. BM25 alone misses. Hybrid (vector + BM25) with a reranker catches 40% more relevant chunks. The pack teaches the patterns.

### Measure retrieval quality

NDCG, MRR, recall@k. Without metrics, you're guessing. The rag-evaluation skill teaches you to measure, then improve.

## What's in the box

- `5 skills` — decision tree + 4 stage skills
- `5 tool adapters` — pi-agent, Claude Code, Cursor, Cline, generic
- `2 worked examples` — chunking comparison + reranker eval
- `Pattern selection` — tradeoffs for each stage
- `Vendor-agnostic` — works with any stack

## Adapters included

These skills were authored for pi-agent, but we include drop-in adapters for the major AI coding tools.

| Tool | Adapter location | What you get |
|------|------------------|--------------|
| pi-agent | `adapters/pi-agent/` | SKILL.md drop-in |
| Claude Code | `adapters/claude-code/` | .claude/commands/*.md + CLAUDE.md |
| Cursor | `adapters/cursor/` | .cursorrules rule sets |
| Cline / Continue | `adapters/cline/` | System-prompt rules |
| Aider / generic | `adapters/generic/` | INSTRUCTIONS.md snippets |

**Same playbook, different packaging.** The adapters translate the methodology into the format each tool expects. Install once, swap agents without re-learning the method.

## Features

- rag-engineering skill — master orchestrator + RAG decision tree
- chunking-strategies skill — fixed-size, semantic, hierarchical, late-chunking, table-aware
- retrieval-patterns skill — vector, BM25, hybrid, rerankers, multi-query, HyDE, query rewriting
- rag-evaluation skill — retrieval metrics (NDCG, MRR, recall@k) + end-to-end metrics + golden sets
- advanced-rag skill — agentic RAG, graph RAG, multimodal RAG, when to escalate
- 5 tool adapters — pi-agent, Claude Code, Cursor, Cline, generic
- 2 worked examples — chunking comparison + reranker evaluation

## FAQ

### Does this work with my vector DB?

Yes. The pack is methodology, not infrastructure. It teaches you to pick the right chunking, embedding, and retrieval patterns. Your vector DB (Pinecone, Weaviate, Qdrant, pgvector, Chroma) doesn't change the patterns.

### How is this different from LangChain / LlamaIndex docs?

Framework docs tell you *what* the framework does. This pack tells you *which pattern to pick and why*. The methodology is portable; the framework isn't.

### I have naive RAG. Will this fix it?

Probably. The first step is rag-evaluation — build a golden set, measure retrieval quality. Then apply the right pattern (often hybrid search + reranker). Most naive RAGs improve 30-50% with one or two pattern swaps.

# AI Cost Optimization Playbook

> [View this product on lib-pro](https://lib-pro-3f8437.gitlab.io/libs/cost-optimization) · Cut your LLM costs by 60-90%. Without sacrificing quality.

**Outcome:** Cut LLM costs by 60-90% without sacrificing quality.

5 skills for cutting LLM API costs without sacrificing quality: the optimization funnel (cache → token → model → batch → fine-tune), token economics, model selection, caching strategies, and FinOps for LLMs. The methodology behind the Buzzfeed 80% cost reduction, packaged as a SKILL.md bundle.

**Price:** £35 — lifetime · **Category:** Production AI Skills · **Tech:** pi-agent, Claude Code, Cursor, Cline, Markdown, OpenAI, Anthropic, Google (vendor-agnostic)

| Metric | Value |
|--------|-------|
| Skills | 5 |
| Layers | 5 |
| Typical savings | 60-90% |

## Quick start

```bash
tar -xzf cost-optimization-0.1.0.tgz && cd cost-optimization-0.1.0

# cost-optimization — The Optimization Funnel

The cheapest LLM call is the one you don't make. The second cheapest is the one that's 100x smaller.

## The 5-Layer Funnel

Apply in order — each layer saves 30-60% when applied.

1. **Stop unnecessary calls** (caching, deduplication) — biggest win, 50-90% reduction
2. **Reduce call size** (token optimization) — second biggest, 20-50% reduction
3. **Use cheaper models** (model selection) — quality-dependent, 50-80% reduction
4. **Batch where possible** (batch API) — 50% off list price
5. **Fine-tune** (only after the above) — capital-intensive, justified by high volume

## The Numbers (Real)

A typical LLM app without optimization:
- 1M API calls/month × $0.02/call = $20,000/month
- After caching: $4,000-10,000/month
- After token optimization: $2,000-5,000/month
- After model selection: $500-2,000/month
- Total reduction: 75-90%

Most teams find 80% waste on their first audit.
```

## Use cases

### 1. Your LLM bill is growing faster than usage

Last month $2k, this month $8k, next month projected $30k. You don't know where the money is going. Finance is asking questions.

**Outcome:** Run the cost audit. Find the waste. Apply the funnel. Cut the bill by 60-90% without losing quality.

### 2. You're using the most expensive model for everything

Sonnet for every call, including simple classification. Haiku would work for 80% of your calls at 1/30 the cost.

**Outcome:** Audit by task type. Route simple tasks to Haiku, complex tasks to Sonnet. Save 60-70% with no quality loss.

### 3. You're building for scale

1k users today, 100k next quarter. At current cost, 100k users = $50k/month. You need a cost-aware architecture from day 1.

**Outcome:** Apply the funnel. Build cost attribution. Set budgets per feature. Scale without the bill scaling linearly.

## Built for

- AI engineers whose LLM bill is growing too fast
- AI engineering managers who need cost attribution across teams
- CTOs who need to defend LLM costs to the board
- Indie hackers who need LLM features to be profitable

## Highlights

### The 5-layer funnel

Cache first (50-90% reduction). Token optimization second (20-50%). Model selection third (50-80%). Batch API fourth (50% off). Fine-tune last. Apply in order.

### Most teams find 80% waste

The first audit almost always reveals 80% waste. Unnecessary calls, oversized prompts, expensive models for simple tasks. The pack teaches you to find it.

### Quality preservation

Cost optimization doesn't mean quality loss. The pack teaches you to measure quality (via evals) and optimize cost with the constraint that quality doesn't drop.

## What's in the box

- `5 skills` — funnel + 4 layer skills
- `5 tool adapters` — pi-agent, Claude Code, Cursor, Cline, generic
- `2 worked examples` — token reduction + budget alerts
- `Cost math per layer` — know the savings
- `Vendor-agnostic` — works with any LLM provider

## Adapters included

These skills were authored for pi-agent, but we include drop-in adapters for the major AI coding tools.

| Tool | Adapter location | What you get |
|------|------------------|--------------|
| pi-agent | `adapters/pi-agent/` | SKILL.md drop-in |
| Claude Code | `adapters/claude-code/` | .claude/commands/*.md + CLAUDE.md |
| Cursor | `adapters/cursor/` | .cursorrules rule sets |
| Cline / Continue | `adapters/cline/` | System-prompt rules |
| Aider / generic | `adapters/generic/` | INSTRUCTIONS.md snippets |

**Same playbook, different packaging.** The adapters translate the methodology into the format each tool expects. Install once, swap agents without re-learning the method.

## Features

- cost-optimization skill — master orchestrator + 5-layer optimization funnel
- token-economics skill — input vs output, prompt caching, batch API, context window math
- model-selection skill — cost/quality tradeoff, distillation, fine-tuning economics
- caching-strategies skill — prompt caching, semantic caching, response caching
- finops-for-llms skill — cost attribution, budgets, alerts, vendor management
- 5 tool adapters — pi-agent, Claude Code, Cursor, Cline, generic
- 2 worked examples — token cost reduction + budget alert setup

## FAQ

### Does this work with my LLM provider?

Yes. The methodology is vendor-agnostic. Apply the same funnel to OpenAI, Anthropic, Google, open-weight, or any combination. The specific tactics differ (Anthropic has prompt caching, OpenAI has batch API); the layers are the same.

### Will cutting costs hurt quality?

Not if you measure quality via evals. The pack teaches you to optimize cost with the constraint that eval scores don't drop. Most teams find 60-90% cost reduction with no measurable quality change.

### How long does the first audit take?

A focused first-pass audit (find the biggest waste) takes a day. Applying the fixes takes 1-2 weeks. The pay-back is usually within the first month of cost savings.

# AI Guardrails & Red Teaming

> [View this product on lib-pro](https://lib-pro-3f8437.gitlab.io/libs/guardrails-red-team) · Ship LLM features that resist prompt injection, jailbreaks, and data exfiltration.

**Outcome:** Ship LLM features that resist the OWASP Top 10 for LLMs.

5 skills for shipping LLM features that are safe in production: the OWASP Top 10 for LLMs as the framework, threat modeling, prompt injection defense (direct + indirect), output guardrails, and red team harness design. The Microsoft + OWASP + NIST AI safety frameworks, packaged as a SKILL.md bundle.

**Price:** £40 — lifetime · **Category:** Production AI Skills · **Tech:** pi-agent, Claude Code, Cursor, Cline, Markdown, OWASP, NIST, Microsoft frameworks

| Metric | Value |
|--------|-------|
| Skills | 5 |
| OWASP risks covered | 10 |
| Defense layers | 4 |

# ai-safety — The LLM Threat Model

Prompt injection is the SQL injection of LLMs. If you don't have a defense, you have a vulnerability.

## The OWASP Top 10 for LLMs

- LLM01: Prompt Injection
- LLM02: Insecure Output Handling
- LLM03: Training Data Poisoning
- LLM04: Model DoS
- LLM05: Supply Chain Vulnerabilities
- LLM06: Sensitive Information Disclosure
- LLM07: Insecure Plugin Design
- LLM08: Excessive Agency
- LLM09: Overreliance
- LLM10: Model Theft

The pack teaches defense patterns for each. LLM01 (Prompt Injection) and LLM08 (Excessive Agency) are the most common production risks.

## The Defense-in-Depth Model

1. **Input validation** (catch obvious attacks before they reach the LLM)
2. **Context separation** (system prompt isolated from user input + tool results)
3. **Output filtering** (catch exfiltration attempts in responses)
4. **Audit logging** (detect attacks after the fact)
5. **Red team testing** (find vulnerabilities before attackers do)

No single layer is sufficient. All 4 are required.
```

## Use cases

### 1. You're shipping an LLM feature to customers

Your feature takes user input, passes it to the LLM, and returns the response. You have no defenses. A user pastes a prompt injection and gets PII out.

**Outcome:** Apply the 4-layer defense model. Audit your input/output flow. Add the missing pieces. Sleep at night.

### 2. You're building an LLM agent with tool use

Your agent reads documents from external sources and uses them as context. Indirect prompt injection is a real risk. Documents can contain attacks.

**Outcome:** Apply context separation. Treat external content as untrusted. Validate before passing to the LLM. Use the threat-modeling skill to map the attack surface.

### 3. You're in a regulated industry

Healthcare, finance, legal. PII handling, audit logging, output filtering are not optional. The regulator will ask.

**Outcome:** Use the guardrails skill to design the audit logging, PII redaction, and output validation. Use the threat-modeling skill to satisfy the auditor.

## Built for

- AI engineers shipping LLM features that handle user data
- Security engineers adding LLM features to existing applications
- AI engineering managers who need a team-wide security standard
- Indie hackers shipping AI products who can't afford a security incident

## Highlights

### OWASP Top 10 for LLMs

The 10 risks every LLM application should defend against, from prompt injection (LLM01) to excessive agency (LLM08). The pack covers the framework and the defense patterns.

### Defense-in-depth, not single layer

Input validation alone fails. Output filtering alone fails. You need all 4: input validation, context separation, output filtering, audit logging. No shortcuts.

### Red team yourself

Don't wait for attackers. Build a red team harness, run it on every PR, catch the obvious vulnerabilities before they reach production.

## What's in the box

- `5 skills` — OWASP, threat model, injection, guardrails, red team
- `5 tool adapters` — pi-agent, Claude Code, Cursor, Cline, generic
- `2 worked examples` — OWASP walkthrough + red team harness
- `Defense-in-depth` — 4 layers, all required
- `OWASP / NIST / Microsoft` — frameworks

## Adapters included

These skills were authored for pi-agent, but we include drop-in adapters for the major AI coding tools.

| Tool | Adapter location | What you get |
|------|------------------|--------------|
| pi-agent | `adapters/pi-agent/` | SKILL.md drop-in |
| Claude Code | `adapters/claude-code/` | .claude/commands/*.md + CLAUDE.md |
| Cursor | `adapters/cursor/` | .cursorrules rule sets |
| Cline / Continue | `adapters/cline/` | System-prompt rules |
| Aider / generic | `adapters/generic/` | INSTRUCTIONS.md snippets |

**Same playbook, different packaging.** The adapters translate the methodology into the format each tool expects. Install once, swap agents without re-learning the method.

## Features

- ai-safety skill — master orchestrator + OWASP Top 10 for LLMs + defense-in-depth model
- threat-modeling skill — LLM-specific: trust boundaries, attack surfaces, asset classification
- prompt-injection-defense skill — direct + indirect injection, attack taxonomy, defense layers
- guardrails skill — output filters, content moderation, schema enforcement, PII redaction
- red-teaming skill — red team harness, attack library, jailbreak testing, regression suite
- 5 tool adapters — pi-agent, Claude Code, Cursor, Cline, generic
- 2 worked examples — OWASP LLM Top 10 walkthrough + red team harness

## FAQ

### Does this replace a guardrail product (Lakera, NeMo Guardrails, etc.)?

No. The pack is methodology — which risks to defend against, where in the architecture to put defenses, what to test for. The vendors are infrastructure that implements some of the defenses. Use both: the pack for the threat model, the vendor for execution.

### How long does a red team exercise take?

A focused first-pass red team (find obvious vulnerabilities) takes 1-2 weeks. Building a continuous red team harness (runs on every PR) takes another 1-2 weeks. After that, it's 1-2 days per audit cycle.

### I'm using OpenAI / Anthropic with their built-in safety. Do I still need this?

Provider safety protects against the most egregious abuse (CSAM, weapons, etc.). It does NOT protect against prompt injection, data exfiltration, or excessive agency. You need application-level defenses. This pack teaches them.

**Outcome:** A color story you don't have to think about.

Color palettes + design tokens built for indie SaaS founders, AI tool builders, and Notion template creators. Every palette ships as Figma Design Tokens (W3C), Tailwind config, CSS variables, and Sketch palette — plus SVG swatches and PNG mockups showing each palette applied to real UI. 10 aesthetic segments (Cyberpunk AI, Editorial SaaS, Brutalist Mono, Warm Indie Maker, Mediterranean Sage, Memphis 90s, Wellness Rose, Notion Pop, Y2K Cyber, Quiet Luxury), 6 hand-picked palettes per segment, AA contrast validated.

**Price:** £15 — lifetime · **Category:** Design Assets Bundle · **Tech:** Figma Tokens Studio, Tailwind CSS, CSS Custom Properties, Sketch, OKLCH color space, WCAG 2.x AA

| Metric | Value |
|--------|-------|
| Palettes | 60 |
| Segments | 10 |
| Formats per palette | 4 |
| AA pass rate (pre-curation) | 90% |

## Quick start

```bash
tar -xzf palette-pack-indie-saas-1.0.0.tgz
```

- # Open contact-sheet.html in any browser to browse all 60 palettes
- # Drop a figma.tokens.json into Tokens Studio
- # Or paste styles.css into your globals.css
- # Or extend tailwind.config with theme.extend.colors

## Code preview

```tsx
{
  "color": {
    "cyberpunk-ai": {
      "bg":               { "value": "#010043", "type": "color" },
      "surface":          { "value": "#03004C", "type": "color" },
      "surface-elevated": { "value": "#00006B", "type": "color" },
      "text":             { "value": "#E8F1FF", "type": "color" },
      "text-muted":       { "value": "#8890A0", "type": "color" },
      "primary":          { "value": "#E12A00", "type": "color" },
      "accent":           { "value": "#6C6D00", "type": "color" },
      "border":           { "value": "#232A36", "type": "color" }
    }
  }
}

// Drop into Tokens Studio → Load from JSON → paste → colors become tokens.
// Every other palette uses the same 8 semantic roles.
// Swap the segment name for any of: cyberpunk-ai, editorial-cream,
// brutalist-mono, warm-indie, mediterranean-sage, memphis-revival,
// soft-wellness-rose, notion-pop, y2k-cyber, quiet-luxury.
```

## Use cases

### 1. AI tool dashboard

Building an AI SaaS dashboard — dark mode by default, neon accents on the primary CTA. Pick a cyberpunk-ai palette, drop the Figma tokens into Tokens Studio, push to your team's library. Every chart, button, and modal uses the system.

**Outcome:** A polished dashboard that doesn't look like every other Bootstrap template.

### 2. Notion template pack

Selling Notion templates on Gumroad. Pick 3-4 notion-pop palettes, mix-and-match across your cover, headers, and callouts. Ship the template with the palette names as 'design system: included'.

**Outcome:** A Notion template that feels intentional, not assembled from random colors.

### 3. Indie SaaS landing page

Landing page for a new indie SaaS. Pick warm-indie-maker for warmth, or brutalist-mono for opinion. The Tailwind config drops into your Next.js project in 30 seconds.

**Outcome:** A landing page that looks like you hired a designer (you didn't).

### 4. Content / docs SaaS

Building a content product — blog, docs, knowledge base. Editorial SaaS Cream palettes are off-white + ink with one accent. Quiet, readable, doesn't fight the content.

**Outcome:** A docs product that doesn't feel like every other Tailwind UI template.

### 5. Figma design system foundation

Starting a new design system in Figma. Import the tokens.json files, push to Tokens Studio, sync to GitHub. Your design tokens are now version-controlled and 10 aesthetic variants ship with the system.

**Outcome:** A design system with 10 variants out of the box, not 1.

## Built for

- Indie SaaS founders shipping fast and tired of looking like every other dashboard
- AI tool builders who want dark-mode-first palettes with neon accents
- Notion template creators who want their covers and callouts to feel intentional
- Designers building design systems — start with 10 segments instead of 1
- Frontend devs who'd rather drop in tokens than fight with HSL math
- Anyone selling digital products on Gumroad who wants a real color story

## Highlights

### 10 vertical-niche segments, 6 palettes each

Cyberpunk AI 2026 for AI dashboards, Editorial SaaS Cream for content products, Brutalist Mono for indie hackers, Warm Indie Maker for landing pages, Mediterranean Sage for wellness tools, Memphis 90s for creator products, Wellness Rose for journaling, Notion Pop for templates, Y2K Cyber for fashion brands, Quiet Luxury for B2B. Each segment has its own hue range, chroma profile, and harmony biases.

### 4 formats per palette — same colors, every framework

Figma Design Tokens (W3C spec) for Tokens Studio. Tailwind config for tailwind.config.js. CSS variables for globals.css. Sketch palette files for Sketch. The colors you see are the same in every format. Pick the one your stack uses.

### 8 semantic roles per palette — not just 5 raw swatches

Every palette defines bg, surface, surface-elevated, text, text-muted, primary, accent, border. That's a design-token system, not a flat list. Drop it in and your UI components just work — buttons, cards, borders, hover states all use the right colors automatically.

### AA contrast validated, then hand-curated

Algorithmic generation (OKLCH + harmony rules) produces 300 candidates. 90% pass WCAG AA on text and UI. The top 60 are picked by score + visual character (the 20% hand curation that separates a real product from a random generator). The contrast ratios are baked into INDEX.json so you can verify before you ship.

### 5 real UI mockup templates + 60 PNG previews

Not dry swatches. SaaS hero landing, dashboard, pricing panel, Notion cover, dark/light compare. Each rendered with 5 flagship palettes at 1200×800 PNG. Plus a 1200×800 hero preview for every curated palette. See exactly what you're getting before you write a line of CSS.

### Commercial license, lifetime updates

Use in unlimited personal and commercial projects. Use in products you sell (SaaS, apps, courses, Notion templates). Lifetime re-downloads from the same payment link. No subscription. No JavaScript-framework-specific gotchas.

- AA contrast validated — text 4.5:1, UI 3:1, generated then hand-curated
- INDEX.json — machine-readable palette lookup with contrast data
- Commercial single-seat license (Studio tier)
- Lifetime updates — buy once, re-download forever

## FAQ

### Why not just use Coolors / Huemint / RealtimeColors?

Those are great for one-off palette exploration. This pack is for people who want 60 production-ready palettes with semantic tokens, in 4 formats, with mockups, with AA contrast already validated. Different tool, different job — this is the shipping artifact, not the brainstorming tool.

### Will these palettes actually look good on my real product?

Yes, by design. Every palette ships with 5 mockup templates (hero, dashboard, pricing, Notion cover, dark/light compare) at 1200×800 PNG. Open the ZIP, browse the mockups, see exactly how each palette looks on real SaaS UI before you write a line of CSS.

### Are the palettes AA accessible?

Yes. All 60 curated palettes pass WCAG AA on text (≥ 4.5:1) and UI elements (≥ 3:1). The algorithmic generator produces ~90% AA-pass rates; the top 60 are picked from those. The exact contrast ratios are in INDEX.json for buyers to verify.

### Can I use these in commercial products?

Yes — single-seat commercial license. Use in unlimited products you build (SaaS, apps, courses, Notion templates, client deliverables). Don't resell the palettes themselves as a competing palette product. Don't redistribute the ZIP publicly.

### What if a palette doesn't fit my project?

You get 60 palettes across 10 aesthetic segments. If none of them fit, the pack probably isn't for you — and that's fine. Pick what works, leave the rest. No refunds on digital goods, but you can always email for help picking.

### How do updates work?

Lifetime updates. When new segments or palettes are added, the ZIP gets re-published to the same Gumroad/Stripe payment link. Re-download any time, no extra charge. No subscription, no recurring fees.
