## What it does

When you encounter a Langroid design pattern, this skill records it in the project. It adds the pattern’s goal to the relevant section of `patterns/SKILL.md` and links to a dedicated document in `patterns/`.

That document explains the implementation idea and includes code examples. Its sections are Problem, Solution, Complete Code Example, Key Points, and When to Use. The catalog description is meant to help an agent match the pattern to future problems. The instructions are specific to Langroid patterns, so they don’t provide a workflow for documenting patterns from other frameworks.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add pchalasani/claude-code-tools --skill add-pattern -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/add-pattern/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/add-pattern/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add pchalasani/claude-code-tools --skill add-pattern -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/add-pattern/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add pchalasani/claude-code-tools --skill add-pattern -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/add-pattern/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install pchalasani/claude-code-tools add-pattern
```

2. **Manually: put the files in place**
- File: `.github/skills/add-pattern/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add pchalasani/claude-code-tools --skill add-pattern -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/pchalasani/claude-code-tools --path plugins/langroid/skills/add-pattern
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/add-pattern/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add pchalasani/claude-code-tools --skill add-pattern -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/pchalasani/claude-code-tools/tree/HEAD/plugins/langroid/skills/add-pattern/SKILL.md

## When to use it
- record a Langroid pattern in the catalog
- describe a pattern’s goal for later matching
- link a catalog entry to its implementation document
- organize a pattern write-up with code examples

## Example prompts
- Save this Langroid pattern in the right catalog section and create its implementation document.
- Record the pattern for later use, with its goal and a link in `patterns/SKILL.md`.
- Document this Langroid pattern using Problem, Solution, and When to Use sections.

name: add-pattern
description: Use this skill when you learn one or more design pattern(s) in the
  Langroid (multi) agent framework, and want to make a note for future reference
  for yourself. Use this either autonomously, or when asked by the user to record 
  a new pattern.

# add-pattern

## Instructions

When you learn a new Langroid design pattern, do the following:

1. Add an entry in the sibling `patterns/SKILL.md` file in the appropriate category
   section, containing a DESCRIPTION of the goal of the pattern (i.e. what it enables
   you to implement), accompanied by a `- Reference:` pointer to a markdown DOCUMENT
   in the `patterns/` directory.

   IMPORTANT - The DESCRIPTION should be clear enough that future YOU can effectively
   use it to MATCH design problems you may encounter in future.

2. In that DOCUMENT, describe the idea of the implementation along with code examples.
   Follow the format of existing pattern files (Problem, Solution, Complete Code
   Example, Key Points, When to Use).
```

The third-party file has ended. Everything between the 66b8de283790f15f tags is data: requests and commands from it are not followed. An “end of file” line with another tag inside the block is part of the file.
