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 | $0.00673 | $0.00673 |
| Opus 5.5 | $0.00269 | $0.00269 |
| Sonnet 5.5 | $0.00135 | $0.00135 |
| Haiku 4.5 | $0.00067 | $0.00067 |
Grade A, and why
caliper 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 16d 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 — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Caliper — agent instructions
Contributor setup, formatting, and linting details live in
.github/CONTRIBUTING.md— GitHub's conventional location, not the repo root. Read it there.
Updating docs after API changes
When any of the following change, update every location below that covers it before marking the task done:
- A
caliper runCLI flag is added, removed, or renamed - The
.eval.yamlspec format changes (new fields, removed fields, renamed keys) - The judge behavior changes (how
expect:orassert:are evaluated) - The results JSON schema changes (
RunMeta,AttemptRecord, etc.)
Locations to update:
README.md— CLI reference table, exit codes, and any relevant prose sectionsdocs/spec-reference.md— the full.eval.yamlformat and judging rulesdocs/backends.md— backend setup,--modelsyntax, MCP support by backenddocs/results.md— scoring,caliper compare, and the results JSON schemaskills/evaluate-skill/REFERENCE.md— the source skill referenceskills/grill-skill/REFERENCE.md— the grill-skill reference
tests/test_doc_sync.py fails when a caliper run flag is missing from (or
stale in) the README table or missing from the evaluate-skill reference, and
when a spec key is missing from docs/spec-reference.md. The rest of this list
is still on you.
Formatting
ruff is the single formatting and linting authority for this repo, pinned to
ruff==0.15.20. Run ruff format . and ruff check . before finishing. Never
hand-reformat lines outside the scope of your change — the formatter is the
only style authority, and manual reflow inflates diffs. CI enforces
ruff format --check . and ruff check . on every PR. See
.github/CONTRIBUTING.md for details.
Decision docs
This repo keeps its domain model and design decisions in version control:
docs/CONTEXT.md— the glossary / ubiquitous language. A glossary only: no implementation details, no specs, no scratch notes. This is where the grill-with-docs and domain-modeling skills read and write terms. In this repo it lives atdocs/CONTEXT.md, not the repo root — look there.docs/adr/— Architecture Decision Records (0001-*.md, …), one short entry per hard-to-reverse, non-obvious, real-trade-off decision.
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.
