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 | $0.02432 | $0.02432 |
| Opus 5.5 | $0.00973 | $0.00973 |
| Sonnet 5.5 | $0.00486 | $0.00486 |
| Haiku 4.5 | $0.00243 | $0.00243 |
Grade A, and why
cursorrules 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cursor Agents Guide (Using Cursor Rules)
This document explains how to use the rules in this repository with Cursor and serves as a single entry point that references the existing rule files. It avoids duplication by linking directly to the .cursor/rules/*.mdc sources.
If you installed these rules via the installer, a project‑local AGENTS.md can be generated that lists only the rules you chose. By default, the installer writes AGENTS.md if absent; it overwrites only when you pass --yes.
How To Use With Cursor
- Open your project in Cursor. Rules under
.cursor/rulesare discovered automatically by Cursor. - Keep this AGENTS.md handy as your quick index to the rule set.
- For installation methods and advanced options, see
README.md.

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.
