## What it does

The skill retrieves current library documentation by querying the Context7 API using curl. The workflow starts with a search call using the library name and topic to locate the internal library identifier. Search results return the identifier, human-readable titles, short descriptions, and snippet counts.

Once the identifier is resolved, the agent fetches the documentation snippets. Responses can be returned in plain text using the txt format parameter or as JSON, which pairs with jq for quick parsing.

Basic usage requires no API key, though requests remain rate-limited. That is a clear reason to keep topic queries specific and avoid spamming calls. Any query strings containing spaces need URL encoding with plus symbols or percentage codes.

## Requirements
- Works with: Context7

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add intellectronica/agent-skills --skill context7 -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/context7/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/context7/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add intellectronica/agent-skills --skill context7 -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/context7/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add intellectronica/agent-skills --skill context7 -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/context7/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install intellectronica/agent-skills context7
```

2. **Manually: put the files in place**
- File: `.github/skills/context7/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add intellectronica/agent-skills --skill context7 -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/intellectronica/agent-skills --path skills/context7
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/context7/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add intellectronica/agent-skills --skill context7 -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/intellectronica/agent-skills/tree/HEAD/skills/context7/SKILL.md

## When to use it
- fetch current library docs when training data is outdated
- verify function signatures and API usage before coding
- retrieve official code examples for specific framework features

## Example prompts
- Look up Context7 documentation for useState in React
- Find FastAPI dependency injection examples using context7

description: Retrieve up-to-date documentation for software libraries, frameworks, and components via the Context7 API. This skill should be used when looking up documentation for any programming library or framework, finding code examples for specific APIs or features, verifying correct usage of library functions, or obtaining current information about library APIs that may have changed since training.

# Context7

## Overview

This skill enables retrieval of current documentation for software libraries and components by querying the Context7 API via curl. Use it instead of relying on potentially outdated training data.

## Workflow

### Step 1: Search for the Library

To find the Context7 library ID, query the search endpoint:

```bash
curl -s "https://context7.com/api/v2/libs/search?libraryName=LIBRARY_NAME&query=TOPIC" | jq '.results[0]'
```

**Parameters:**
- `libraryName` (required): The library name to search for (e.g., "react", "nextjs", "fastapi", "axios")
- `query` (required): A description of the topic for relevance ranking

**Response fields:**
- `id`: Library identifier for the context endpoint (e.g., `/websites/react_dev_reference`)
- `title`: Human-readable library name
- `description`: Brief description of the library
- `totalSnippets`: Number of documentation snippets available

### Step 2: Fetch Documentation

To retrieve documentation, use the library ID from step 1:

```bash
curl -s "https://context7.com/api/v2/context?libraryId=LIBRARY_ID&query=TOPIC&type=txt"
```

**Parameters:**
- `libraryId` (required): The library ID from search results
- `query` (required): The specific topic to retrieve documentation for
- `type` (optional): Response format - `json` (default) or `txt` (plain text, more readable)

## Examples

### React hooks documentation

```bash
# Find React library ID
curl -s "https://context7.com/api/v2/libs/search?libraryName=react&query=hooks" | jq '.results[0].id'
# Returns: "/websites/react_dev_reference"

# Fetch useState documentation
curl -s "https://context7.com/api/v2/context?libraryId=/websites/react_dev_reference&query=useState&type=txt"
```

### Next.js routing documentation

```bash
# Find Next.js library ID
curl -s "https://context7.com/api/v2/libs/search?libraryName=nextjs&query=routing" | jq '.results[0].id'

# Fetch app router documentation
curl -s "https://context7.com/api/v2/context?libraryId=/vercel/next.js&query=app+router&type=txt"
```

### FastAPI dependency injection

```bash
# Find FastAPI library ID
curl -s "https://context7.com/api/v2/libs/search?libraryName=fastapi&query=dependencies" | jq '.results[0].id'

# Fetch dependency injection documentation
curl -s "https://context7.com/api/v2/context?libraryId=/fastapi/fastapi&query=dependency+injection&type=txt"
```

## Tips

- Use `type=txt` for more readable output
- Use `jq` to filter and format JSON responses
- Be specific with the `query` parameter to improve relevance ranking
- If the first search result is not correct, check additional results in the array
- URL-encode query parameters containing spaces (use `+` or `%20`)
