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 | $0.00474 | $0.00474 |
| Opus 5.5 | $0.00190 | $0.00190 |
| Sonnet 5.5 | $0.00095 | $0.00095 |
| Haiku 4.5 | $0.00047 | $0.00047 |
Grade A, and why
ratel-local 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 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
AGENTS.md
Guidance for coding agents working on Ratel Local — the MCP gateway that fronts
Claude Code / Codex / Cursor with capability search. Shipped as @ratel-ai/ratel-local.
pnpm workspace: packages/core, packages/ui, apps/ratel-local, e2e/.
Setup
- Node 24+, pnpm 10+.
pnpm install
Core commands
pnpm build # tsc → dist/
pnpm typecheck
pnpm lint # biome
pnpm test # vitest
CI (.github/workflows/ts.yml) runs all four on every PR. Land green.
Rules
- TDD on library and CLI logic. Red → green → refactor (vitest).
- Conventional-commits-ish prefixes:
feat:,fix:,chore:,docs:,refactor:,ci:. Scopes optional but useful (fix(cli):). - No tool-attribution lines in commit messages (no
Co-Authored-By: Claude, etc.). - Keep PRs focused — one logical change per PR. Update
README.md/CHANGELOG.mdin the same PR when the change affects them. - ADRs are immutable once Accepted (
docs/adr/) — supersede with a new ADR rather than editing.
Ways of working
- Avoid breaking changes whenever avoidable. Prefer additive, backward-compatible changes. When a break is genuinely unavoidable, call it out explicitly (PR description +
CHANGELOG.md) and provide a migration path. - Develop behind feature flags. Gate new features — and any change to existing behaviour — behind a flag/config that is off by default, so it can ship dark, be rolled out incrementally, and be reverted without a code change. Remove the flag once the behaviour is the stable default.

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.
