SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill automates the discovery, retrieval, and caching of library documentation from Context7 MCP, reducing manual lookup and context-switching for developers.

Core Features & Use Cases

  • Auto-detects libraries from the project tech context or explicit input and resolves Context7 IDs.
  • Fetches and caches library docs (with code examples and API references) to enable quick reference during development.
  • Stores documentation in standardized Markdown with context7 metadata for downstream tooling and planning.

Quick Start

Run the skill with explicit libraries, for example /jaan-to:dev-docs-fetch fastapi to fetch and cache its Context7 documentation.

FAQPage Schema
How do I fetch and cache library documentation automatically?

Fetch and cache library documentation by resolving Context7 IDs from tech context. The skill retrieves API references and code examples, storing them in standardized Markdown files with a 7-day TTL cache for quick access and downstream planning.

What is Context7 MCP and how does it help with developer onboarding?

Context7 MCP is a protocol used to retrieve library documentation. This skill automates discovery and resolution of Context7 IDs, reducing manual lookup and context-switching to accelerate developer onboarding with rich API references.

Can I auto-detect target libraries from my project tech context?

Yes, you can auto-detect target libraries from your project tech context. The skill resolves Context7 IDs automatically without explicit input, handling retrieval and storage of rich references for downstream tooling.

How do I cache Context7 markdown files for downstream planning?

Cache Context7 markdown files by running the skill with a target library. It enforces a 7-day TTL cache, preserves created and updated metadata, and writes standardized context7 markdown files for downstream planning and tooling integration.

What are the limitations of the 7-day TTL cache for library documentation?

The 7-day TTL cache limits documentation freshness, requiring re-fetching after expiration to get the latest API references. The skill preserves created and updated metadata but does not support real-time synchronization with Context7 MCP.
