Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00058 | $0.00452 |
| Opus 5 | $0.00029 | $0.00226 |
| Sonnet 5 | $0.00012 | $0.00090 |
| Haiku 4.5 | $0.00006 | $0.00045 |
Grade A, and why
context7-mcp 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 6d 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.
This is a copy
97% identical to documentation-lookup — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
When the user asks about libraries, frameworks, or needs code examples, use Context7 to fetch current documentation instead of relying on training data.
When to Use This Skill
Activate this skill when the user:
- Asks setup or configuration questions ("How do I configure Next.js middleware?")
- Requests code involving libraries ("Write a Prisma query for...")
- Needs API references ("What are the Supabase auth methods?")
- Mentions specific frameworks (React, Vue, Svelte, Express, Tailwind, etc.)
How to Fetch Documentation
Step 1: Resolve the Library ID
Call resolve-library-id with:
libraryName: The library name extracted from the user's questionquery: The user's full question (improves relevance ranking)
Step 2: Select the Best Match
From the resolution results, choose based on:
- Exact or closest name match to what the user asked for
- Higher benchmark scores indicate better documentation quality
- If the user mentioned a version (e.g., "React 19"), prefer version-specific IDs
Step 3: Fetch the Documentation
Call query-docs with:
libraryId: The selected Context7 library ID (e.g.,/vercel/next.js)query: The user's specific question
Step 4: Use the Documentation
Incorporate the fetched documentation into your response:
- Answer the user's question using current, accurate information
- Include relevant code examples from the docs
- Cite the library version when relevant
Guidelines
- Be specific: Pass the user's full question as the query for better results
- Version awareness: When users mention versions ("Next.js 15", "React 19"), use version-specific library IDs if available from the resolution step
- Prefer official sources: When multiple matches exist, prefer official/primary packages over community forks
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.

context7-mcp is a skill published in the GitHub repository myths-labs/muse (32 stars, last pushed 1mo ago), licensed MIT. It adds 58 tokens to every session and 452 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 97% identical to documentation-lookup, differing in 2 lines, and is treated as a copy.

project-brain
Triggers (all require explicit user request — do NOT activate just because a brain/ folder exists): (1) The user wants to set up project-level memory ("set up project brain", "scaffold project context", "init project brain", "建项目脑"). (2) The user is in a directory containing brain/ AND explicitly asks to resume /…
mex-inbox
Prepare and manage governed MEX Inbox proposals for durable Spec-family knowledge. Use when the user clearly asks to capture, create, save, or draft a MEX product Spec, requirement, constraint, acceptance criterion, or durable product-spec decision for team review, or explicitly invokes /mex-inbox or $mex-inbox. Do…
mex-relay
Prepare and manage durable MEX team handoffs. Use when the user asks to hand work to a person or team, prepare an end-of-session handoff, save what the next engineer needs, create a MEX Relay, take or close a Relay, or explicitly invokes /mex-relay or $mex-relay. Treat Relay as a memory and context baton, not chat…
engram
Local-first personal AI identity and memory layer for MCP-compatible coding tools (Claude Code, Codex, Cursor, and others). Use this skill when the user wants to continue from a previous session ("continue from last session", "pick up where we left off"), recall a past decision ("what did we decide", "what was our…
