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 | $0.00020 | $0.00253 |
| Opus 5 | $0.00010 | $0.00127 |
| Sonnet 5 | $0.00004 | $0.00051 |
| Haiku 4.5 | $0.00002 | $0.00025 |
Grade A, and why
context7-docs 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 2d 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.
What it actually says
Documentation Research (Context7 MCP)
Consult context7 MCP server for library/package/framework information.
When you need to understand or use any library, package, or framework:
- Use context7 first - Query the MCP server for up-to-date documentation
- Resolve library ID - Use
resolve-library-idto find the correct library - Get documentation - Use
get-library-docswith appropriate mode:mode='code'- For API references, code examples, specific methodsmode='info'- For concepts, architecture, getting started guides
- Verify current practices - Documentation from context7 is authoritative
Do NOT:
- Rely solely on training data for library-specific details
- Guess at API signatures or method names
- Use outdated patterns when current docs are available
Example scenarios:
- Adding a new dependency → Query context7 for latest usage patterns
- Debugging library behavior → Check context7 for current API documentation
- Implementing framework features → Consult context7 for best practices
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-docs is a cursor rule published in the GitHub repository GoranErhartic/cursor-development-rules (19 stars, last pushed 6mo ago), licensed MIT. It adds 20 tokens to every session and 253 once invoked, about $0.0001 per session on Opus 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 2026-08-30.
