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 | $0.01992 | $0.01992 |
| Opus 5.5 | $0.00797 | $0.00797 |
| Sonnet 5.5 | $0.00398 | $0.00398 |
| Haiku 4.5 | $0.00199 | $0.00199 |
Grade A, and why
test-kitchen CLAUDE.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.
How it starts
The opening of the file, as written. The whole thing — 239 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Test Kitchen Plugin
Overview
Test Kitchen provides two gate skills for parallel implementation:
| Skill | Gate | When |
|---|---|---|
test-kitchen:omakase-off |
Entry | FIRST on any build/create/implement request |
test-kitchen:cookoff |
Exit | At design→implementation transition |
Skills Included
| Skill | Triggers | Description |
|---|---|---|
test-kitchen:omakase-off |
(1) FIRST on build/create, (2) During brainstorming on indecision, (3) Explicit request | Wraps brainstorming, offers parallel design exploration |
test-kitchen:cookoff |
At "let's implement" moments | Wraps implementation, offers parallel execution |

Key Design Principle
Skills need aggressive triggers to work.
Skills can't passively detect "uncertainty" or "readiness" - they must claim specific moments in the conversation flow:
- Omakase-off: Claims the BUILD/CREATE moment (before brainstorming)
- Cookoff: Claims the IMPLEMENT moment (after design)
Both skills present choices to the user, allowing them to opt into parallel execution or continue with standard workflows.

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.

test-kitchen CLAUDE.md is an instructions file published in the GitHub repository 2389-research/test-kitchen (4 stars, last pushed 1mo ago), licensed MIT. It adds 1,992 tokens to every session, about $0.0080 per session on Opus 5.5. 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.
