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 | $0.00476 | $0.00476 |
| Opus 5 | $0.00238 | $0.00238 |
| Sonnet 5 | $0.00095 | $0.00095 |
| Haiku 4.5 | $0.00048 | $0.00048 |
Grade A, and why
kamae-ts 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 2d 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.

Repository overview
kamae-ts is a plugin repository of coding-agent skills (SKILL.md-based) for functional domain modeling in server-side TypeScript. Two skills today: kamae (code generation) and kamae-review (adversarial review). Skills are installed via gh skill install iwasa-kosui/kamae-ts <skill> or the skills CLI. There is no application code; the repository primarily contains Markdown skill files, supporting documentation, build scripts, metadata, and CI workflows.
Benchmark work
benchmarks/ contains a historical PRD generation harness whose acceptance-based
comparison was rejected as a design-effectiveness evaluation. See
benchmarks/README.md for that protocol and its limitations.
Run bun run benchmark:typecheck and bun run benchmark:test for harness changes.
CI validates the harness and dry-run inputs without model calls.
Do not use functional tests as skill scores or eligibility gates. Establish the
design distinctions and calibrate their assessment before launching new comparisons.
See benchmarks/design-evaluation.md for the proposed DMMF-based evaluation criteria;
that proposal is not yet an implemented or calibrated grader.
benchmarks/design-scenarios/ contains the new initial/change tasks and evaluator
observation maps. Its CLI prepares inputs only and is independent of the historical
runner. Run bun run benchmark:scenarios check and
bun run benchmark:scenarios:test after changes to these inputs or their packaging.
Show benchmarks/design-scenarios/REVIEW.ja.md before model execution; execution
is currently pending human scenario review. A later comparison also requires
the calibrated assessment procedure described in the proposal.
Worktree conventions
This repo uses git worktree under .wt/<branch-name>/. Session-start hooks create the worktree automatically; git wt -d <branch> removes it after merge. PRs are drafted, then promoted to ready after self-review.
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.

kamae-ts CLAUDE.md is an instructions file published in the GitHub repository iwasa-kosui/kamae-ts (55 stars, last pushed 3d ago), licensed MIT. It adds 476 tokens to every session, about $0.0024 per session on Opus 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 2026-08-30.
