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 | $0.00183 | $0.00183 |
| Opus 5.5 | $0.00073 | $0.00073 |
| Sonnet 5.5 | $0.00037 | $0.00037 |
| Haiku 4.5 | $0.00018 | $0.00018 |
Grade A, and why
cursorrules 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.
What it actually says
This is Kevin Z's Claude Code Kit — a comprehensive skill/command/hook system for Claude Code (Anthropic's CLI).
Structure:
- skills//SKILL.md — On-demand skill definitions (140+)
- commands/.md — Slash command definitions (55+)
- hooks/ — Lifecycle hooks (Node.js, registered in hooks.json)
- templates/ — Project starter templates
- lib/ — Shared libraries (terminal-art.sh, terminal-art.js)
- BIBLE.md, CHEATSHEET.md, SKILLS-INDEX.md — Reference documentation
Key mega-skills: mega-seo, mega-design, mega-testing, mega-marketing, mega-saas, mega-devops Each mega-skill is a directory containing absorbed sub-skills with a router SKILL.md.
Do not modify install.sh, setup.sh, or setup-overwrite.sh without understanding the full installation flow.
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.

cursorrules is a cursor rule published in the GitHub repository KevinZai/commander (6 stars, last pushed today), licensed MIT. It adds 183 tokens to every session, about $0.0007 per session on Opus 5.5. A static security scan graded it A with 0 findings.
