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 | $0.00518 | $0.00518 |
| Opus 5.5 | $0.00207 | $0.00207 |
| Sonnet 5.5 | $0.00104 | $0.00104 |
| Haiku 4.5 | $0.00052 | $0.00052 |
Grade A, and why
skill-gate 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.

Linting & formatting
ESLint (code quality) and Prettier (formatting) are configured to work together
without conflicts: eslint-config-prettier is applied last in the flat config,
so ESLint never reports on anything Prettier owns.
After changing any code, run:
npm run fix:all
This auto-fixes lint issues (eslint . --fix) and then formats every file
(prettier --write .). It is the single command to leave the tree clean.
All scripts
| Command | What it does |
|---|---|
npm run fix:all |
Auto-fix lint issues, then format everything |
npm run lint |
Report ESLint problems (no changes) |
npm run lint:fix |
Auto-fix ESLint problems |
npm run format |
Format all files with Prettier |
npm run format:check |
Verify formatting without writing (CI-friendly) |
npm run check |
lint + format:check — read-only gate, no writes |
First-time setup: npm install.

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.
