Context7

Use this skill to fetch current documentation through the Context7 CLI.

Workflow

1. Resolve the library name to a Context7 library ID with bunx ctx7 library.
2. Pick the best match:
   • Prefer official docs and higher benchmark scores.
   • If the top result looks wrong, inspect the next few entries before choosing.
   • Use --json when you want to filter results with jq.
3. Fetch focused documentation with bunx ctx7 docs <query>.
4. Answer from the retrieved docs, not from stale memory.

Commands

Search for a library

Use readable output when browsing candidates:

bunx ctx7 library react hooks

Use JSON output when you want to inspect fields or filter with jq:

bunx ctx7 library react hooks --json

The JSON array includes fields such as:

• id: Context7 library ID to use with bunx ctx7 docs
• title: Human-readable library name
• description: Summary of the library or docs source
• benchmarkScore: Relevance/quality score
• versions: Available versions, when present

Fetch documentation

Use the chosen library ID and a task-focused query:

bunx ctx7 docs /facebook/react "useEffect examples"

Use JSON output when you need structured snippets:

bunx ctx7 docs /facebook/react "useEffect examples" --json

The JSON response includes:

• codeSnippets: Code examples with titles, descriptions, languages, and code blocks
• infoSnippets: Explanatory text snippets for the topic

Examples

React hooks documentation

# Find likely React library IDs
bunx ctx7 library react hooks

# Fetch current docs and examples
bunx ctx7 docs /facebook/react "useEffect examples"

Next.js routing documentation

# Search for the right Next.js docs source
bunx ctx7 library nextjs routing

# Fetch app router documentation
bunx ctx7 docs /vercel/next.js "app router"

FastAPI dependency injection

# Search for FastAPI docs
bunx ctx7 library fastapi dependencies

# Fetch dependency injection guidance
bunx ctx7 docs /fastapi/fastapi "dependency injection"

Tips

• Prefer bunx ctx7 docs default output when you want readable text in the terminal.
• Prefer --json when you need to pipe into jq or inspect fields precisely.
• Use specific queries such as "server actions", "dependency injection", or "useEffect cleanup" to improve relevance.
• If a library has multiple plausible entries, prefer official docs over mirrors or secondary sources.
• If the user cares about a specific version, check whether versions are listed in the search results and choose the matching library entry.
