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 | $0.00260 | $0.00260 |
| Opus 5 | $0.00130 | $0.00130 |
| Sonnet 5 | $0.00052 | $0.00052 |
| Haiku 4.5 | $0.00026 | $0.00026 |
Grade A, and why
agent-energy-arena 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 11d 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.

Issue tracker
Issues live as markdown files under .scratch/<feature>/. See docs/agents/issue-tracker.md.
Triage labels
Canonical five-role vocabulary, no overrides. See docs/agents/triage-labels.md.
Domain docs
Single-context: CONTEXT.md + docs/adr/ at the repo root. See docs/agents/domain.md.
Feedback loops
This is a Python project. There is no npm. Run the gates via the Makefile:
make test— pytestmake typecheck— mypy (configured inpyproject.toml)make lint— ruff lintmake format— ruff format in-place;make format-checkto verifymake check— lint + format-check + typecheck + test, in that order. Run this before every commit. It is the canonical pre-commit gate.
If any gate fails, fix the underlying issue rather than skipping the gate. Configuration lives in [tool.ruff] and [tool.mypy] of pyproject.toml.
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.
