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 | $0.00147 | $0.00147 |
| Opus 5 | $0.00073 | $0.00073 |
| Sonnet 5 | $0.00029 | $0.00029 |
| Haiku 4.5 | $0.00015 | $0.00015 |
Grade A, and why
rulelens AGENTS.md 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 9d 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
Repository Instructions
RuleLens is a zero-runtime-dependency Node.js CLI that explains which AI coding-agent instruction files apply to a target path.
Development
- Support Node.js 20 and newer.
- Use ES modules and the Node.js standard library.
- Keep scanner output deterministic and local-only.
- Do not execute, evaluate, or remotely resolve discovered instructions.
- Treat vendor-dependent semantic selection as conditional, not certain.
- Preserve the versioned JSON result shape unless making an explicit schema change.
Validation
Run before finishing:
npm run check
npm test
node bin/rulelens.js check . --strict
Add fixture-backed tests for every new rule format, glob behavior, or diagnostic.
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.

rulelens AGENTS.md is an instructions file published in the GitHub repository divyanshu-iitian/rulelens (1 stars, last pushed 1mo ago), licensed MIT. It adds 147 tokens to every session, about $0.0007 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 2026-08-31.
