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 | $0.00033 | $0.00900 |
| Opus 5.5 | $0.00013 | $0.00360 |
| Sonnet 5.5 | $0.00007 | $0.00180 |
| Haiku 4.5 | $0.00003 | $0.00090 |
Grade A, and why
context7 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 1mo 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.

Context7 — Up-to-Date Documentation Expert
Eliminate LLM hallucinations and outdated API usage with Context7. Expert in fetching live, version-specific documentation.
When to Use This Skill
- When questions arise about library APIs
- "How to do X?" questions
- Setup/configuration guides
- Version changelogs and migration guides
- Searching for solutions to error messages
Setup
# Install Context7 CLI
npx ctx7 setup
# Or with API key
CONTEXT7_API_KEY=your-key ctx7 docs /vercel/next.js "app router"
Core Commands
Find a Library
ctx7 library nextjs "middleware authentication"
ctx7 library prisma "relation queries"
ctx7 library fastify "reply hooks"
Fetch Docs
# General query
ctx7 docs /vercel/next.js "server actions"
ctx7 docs /prisma/prisma "nested writes"
ctx7 docs /fastify/fastify "error handling"
# Version-specific
ctx7 docs /vercel/next.js@14 "caching"
ctx7 docs /vercel/next.js@15 "caching" # different behavior!
MCP Tool Usage (if supported)
resolve-library-id:
libraryName: "nextjs"
query: "middleware jwt authentication"
query-docs:
libraryId: "/vercel/next.js"
query: "middleware jwt authentication"

Workflow: When a Library Question Arrives
1. ctx7 library <name> <query> → find ID
2. ctx7 docs <id> <query> → fetch docs
3. Review the fetched documentation
4. Write the implementation
5. Add doc ID as reference
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 is a skill published in the GitHub repository mtnyilmaz/agents (6 stars, last pushed 5mo ago), licensed MIT. It adds 33 tokens to every session and 900 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

Take any book (EPUB/PDF), produce a personalized chapter-by-chapter analysis. Each chapter is preserved in detail (The Chapter) and mirrored back to the reader's actual life (The Mirror) using brain context.
