review-evals

review-evals is a skill for Claude Code from rikdc/ai-skills. It costs 103 tokens per session (1,250 once invoked), scanned A, original, MPL-2.0.

A review guide for judging evaluation scenarios and agent skills. It covers questions that automated checks cannot answer, such as whether a test distinguishes good work and whether its scoring rules are fair.

In plain words
What is it for?
Use it to review skills, pull requests, working branches, and pending evaluation results before accepting them.
Why use it?
Automated checks can verify file layouts and calculations but cannot tell whether a scenario is meaningful or whether a skill gives useful guidance.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

review-evals 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 yesterday.

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.

Review Evals - judgement over evals and skills

Reviews the parts of a skill or eval that a script cannot decide. The deterministic gate (tests/test-evals.sh, run by make test and in CI) already covers layout, rubric arithmetic, fixture hygiene, manifests and frontmatter conventions. Never spend judgement on what that gate decides: run it first and read its findings.

Nothing here runs in CI. A review needs a model, so it runs on a contributor's machine, and it only ever reads refs you trust.

Scope the review

  • An eval run left pending criteria: --result <dir> (see "Grade a run").
  • A pull request: gh pr diff <number> plus tests/test-evals.sh --changes <base-ref> to list the skills and scenarios it touches.
  • A working branch: tests/test-evals.sh --changes origin/main.

Judge a scenario

Read task.md, criteria.json, inputs/setup.sh, the scenario's optional checks.sh, and the unit (SKILL.md or command) the scenario claims to exercise. Then ask, in this order:

  1. Does it discriminate? Name the run that scores well without the unit's guidance. If none exists - the task states the answer, or a criterion holds for any outcome (git log -1, an artifact the task hands over) - the scenario proves nothing. This is the failure that matters most.
  2. Can a correct run pass every criterion? Look for a rubric item the task's own end state contradicts: a clean working tree when the task asks for an untracked artifact, a heading the final step moves, a file the fixture never creates.
  3. Is every criterion documented by the unit? Grade only behaviour the unit states. If the behaviour is worth testing but undocumented, put it in the task instead of the rubric.
  4. Does the task leak the process? If the task spells out the unit's own procedure step by step, an agent without the unit passes. Keep intent in the task; leave the process to the unit.
  5. Is the shim faithful? A recording shim must parse like the real tool - long and short flags, --flag=value, - for stdin, values that begin with - - and record what the tool would infer, not only what it receives.
  6. Is the fixture honest? Deterministic, prompt-free, executable, no network, writes only inside the sandbox, and no checked-in file the script overwrites.

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.
