context7-efficientlisted

Token-efficient library documentation fetcher using Context7 MCP with 86.8% token savings through intelligent shell pipeline filtering. Fetches code examples, API references, and best practices for JavaScript, Python, Go, Rust, and other libraries. Use when users ask about library documentation, need code examples, want API usage patterns, are learning a new framework, need syntax reference, or troubleshooting with library-specific information. Triggers include questions like "Show me React hooks", "How do I use Prisma", "What's the Next.js routing syntax", or any request for library/framework documentation.

# Context7 Efficient Documentation Fetcher Fetch library documentation with automatic 77% token reduction via shell pipeline. ## Quick Start **Always use the token-efficient shell pipeline:** ```bash # Automatic library resolution + filtering bash scripts/fetch-docs.sh --library <library-name> --topic <topic> # Examples: bash scripts/fetch-docs.sh --library react --topic useState bash scripts/fetch-docs.sh --library nextjs --topic routing bash scripts/fetch-docs.sh --library prisma --topic queries ``` **Result:** Returns ~205 tokens instead of ~934 tokens (77% savings). ## Standard Workflow For any documentation request, follow this workflow: ### 1. Identify Library and Topic Extract from user query: - **Library:** React, Next.js, Prisma, Express, etc. - **Topic:** Specific feature (hooks, routing, queries, etc.) ### 2. Fetch with Shell Pipeline ```bash bash scripts/fetch-docs.sh --library <library> --topic <topic> --verbose ``` The `--verbose` flag shows token savings statistics. ### 3. Use Filtered Output The script automatically: - Fetches full documentation (934 tokens, stays in subprocess) - Filters to code examples + API signatures + key notes - Returns only essential content (205 tokens to Claude) ## Parameters ### Basic Usage ```bash bash scripts/fetch-docs.sh [OPTIONS] ``` **Required (pick one):** - `--library <name>` - Library name (e.g., "react", "nextjs") - `--library-id <id>` - Direct Context7 ID (faster, skips resolution) **Optional:** - `--t
