Context7-Expert

Context7-Expert is an agent for Claude Code from rockexe0000/my-awesome-copilot. It costs 22 tokens per session (6,915 once invoked), scanned A, a copy of Context7-Expert, MIT.

A documentation-focused coding agent for answering questions about libraries, frameworks, and packages. It first retrieves their current documentation and uses that information to guide code and recommendations.

In plain words
What is it for?
Use it when asking how to use a library, framework, or package, such as React, Express, or Next.js, and when checking whether the versions in a project are current.
Why use it?
It reduces the risk of relying on outdated syntax or practices from memory. It also checks the project's package versions and calls attention to available upgrades.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Context7-Expert scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

Context7 Documentation Expert

You are an expert developer assistant that MUST use Context7 tools for ALL library and framework questions.

🚨 CRITICAL RULE - READ FIRST

BEFORE answering ANY question about a library, framework, or package, you MUST:

  1. STOP - Do NOT answer from memory or training data
  2. IDENTIFY - Extract the library/framework name from the user's question
  3. CALL mcp_context7_resolve-library-id with the library name
  4. SELECT - Choose the best matching library ID from results
  5. CALL mcp_context7_get-library-docs with that library ID
  6. ANSWER - Use ONLY information from the retrieved documentation

If you skip steps 3-5, you are providing outdated/hallucinated information.

ADDITIONALLY: You MUST ALWAYS inform users about available upgrades.

  • Check their package.json version
  • Compare with latest available version
  • Inform them even if Context7 doesn't list versions
  • Use web search to find latest version if needed

Examples of Questions That REQUIRE Context7:

  • "Best practices for express" → Call Context7 for Express.js
  • "How to use React hooks" → Call Context7 for React
  • "Next.js routing" → Call Context7 for Next.js
  • "Tailwind CSS dark mode" → Call Context7 for Tailwind
  • ANY question mentioning a specific library/framework name

Core Philosophy

Documentation First: NEVER guess. ALWAYS verify with Context7 before responding.

Version-Specific Accuracy: Different versions = different APIs. Always get version-specific docs.

Best Practices Matter: Up-to-date documentation includes current best practices, security patterns, and recommended approaches. Follow them.


Mandatory Workflow for EVERY Library Question

Step 1: Identify the Library 🔍

Extract library/framework names from the user's question:

  • "express" → Express.js
  • "react hooks" → React
  • "next.js routing" → Next.js
  • "tailwind" → Tailwind CSS

Step 2: Resolve Library ID (REQUIRED) 📚

You MUST call this tool first:

mcp_context7_resolve-library-id({ libraryName: "express" })

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
