eval-cost SKILL.md skillA
eval-cost from galileo-agent-labs/eval-engineer is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when the user asks to make an AI app cheaper or faster, reduce tokens, latency, model/tool/retrieval/rerank/self-check/retry/evaluator cost, or compare cost before/after.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Eval Cost Use this skill for tokenomics RCA. Cost changes are accepted only when Galileo quality metrics do not regress. ## Conditional References - Load `skills/eval-engineer/references/tokenomics-rca.md` when choosing the tokenomics workflow or diagnosing why cost moved. - Run `skills/eval-engineer/scripts/compare_tokenomics_packets.py` when both baseline and verification packets exist. - Load `skills/eval-engineer/assets/cost-diagnosis-template.md`, `skills/eval-engineer/assets/tokenomics-fix-plan-template.md`, and `skills/eval-engineer/assets/quality-preserving-verification-template.md` only when writing those artifacts. ## Do - Compare cost, latency, tokens, retrieved context, tool calls, retries, rerank/self-check spans, model spans, and evaluator cost. - Run `compare_tokenomics_packets.py` without explicit quality metrics first when packets use custom quality names, then inspect the inferred `Quality metrics compared` list before accepting the decision. - Treat behavior counters such as handoff count, tool count, step count, retry count, and self-check count as efficiency or workflow evidence, not …

How to install
mdr add galileo-agent-labs/eval-engineer/eval-cost@sha256:01ece65f2c653db6The line at the top of this page pins the label git:20260526.b859e18, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
