What is run-skill-evals?

A command for comparing a skill’s output when the skill is available with output when it is not. An evaluation is a check of response quality, not a required merge test.

Use it after changing a skill, its description, or the model used with it, and when assessing a new company-specific skill.

It shows whether a changed skill or model actually improves results before release, while keeping the check separate from the normal code gate.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00637
Opus 5.5	$0.00000	$0.00255
Sonnet 5.5	$0.00000	$0.00127
Haiku 4.5	$0.00000	$0.00064

Security

Grade A, and why

run-skill-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 2mo 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 — 38 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/run-skill-evals

Run with-skill vs without-skill output evals for a skill (Tier 2 style). Soft quality signal — not a merge gate.

Skill / playbook

Follow skills/skill-optimizer → references/eval-loop.md (or .agents/skills/skill-optimizer in adopter apps). Full runbook: docs/evaluating-skills.md.

Usage

/run-skill-evals
/run-skill-evals skills/spec-driven-workflow
/run-skill-evals .agents/skills/my-company-skill

When to use

You changed a skill’s behavior or description, or switched models
You are shipping a company skill and need with/without evidence before commit

Do not re-benchmark every PR. For stock first-party skills, trust published numbers in docs/evals/SCORECARD.md unless the above applies.

Behavior

Locate the target skill (ask if unclear). Prefer kit skills/<name> or adopter .agents/skills/<name>.
Confirm evals/evals.json exists (and ideally evals/trigger/eval_queries.json). If missing, stop and point to /optimize-skill first.
Package cases (pick one):
- This kit repo: run ./scripts/run-skill-evals-soft.sh --skill <name> → work under .adsk-tier2-out/<name>/.
- Adopter app (no kit scripts): read prompts from .agents/skills/<name>/evals/evals.json directly; create a gitignored workspace (e.g. .adsk-tier2-out/<name>/) with with_skill/ and without_skill/ arms per case.
For each eval case, in a clean context:
- with_skill — skill available; paste the prompt; save output
- without_skill — same prompt without the skill (or prior version); save output
Grade each assertion PASS/FAIL with evidence into grading.json (or equivalent). Prefer mechanical checks when possible.
Summarize pass-rate Δ (and token/time Δ if available). For kit first-party skills, offer a SCORECARD paste row; for company skills, report in-chat / PR notes (do not invent kit SCORECARD edits unless asked).
Required close-out: load skill-optimizer → references/eval-loop.md → After grading — recommended next actions. Append a Recommended next actions section (Do now / Do next / Skip) mapped from the decision table — fix with_skill FAILs first, then SCORECARD/PR notes, then assertion tighten. Offer to execute the top action when it is a small obvious edit. Do not end on scores alone.
Reminder: Tier 1 (./scripts/check-skills-ci.sh in the kit) only checks harness shape — it does not replace this loop.

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.
