eval-diagnose SKILL.md skillA

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

Install it, pinned
mdr add galileo-agent-labs/eval-engineer/eval-diagnose@git:20260529.4056a23

Pins git:20260529.4056a23 in mdr.lock. Pin the fingerprint instead.

Use when Galileo evidence is available and the user asks why a trace, session, log stream, experiment, metric, or AI app behavior failed, regressed, or became unsafe.

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 Diagnose

Use this skill for evidence-backed RCA once a packet, URL-derived evidence, or
trace/session/log-stream context is available.

## Required Reference

Use `skills/eval-engineer/references/rca-recipe.md`,
`skills/eval-engineer/references/debug-packets.md`,
`skills/eval-engineer/references/evidence-provenance.md`, and
`skills/eval-engineer/assets/diagnosis-template.md`.

## Do

- Start from fetched evidence, not source-code guesses.
- Name the failing metric contract and what it proves.
- Label hosted Galileo evidence separately from local deterministic packets
  before making metric or score claims.
- Inspect traces, spans, sessions, tool calls, retrieval context, and scorer
  status to classify the fix surface.
- Classify the fix surface: prompt, tool schema, adapter, retriever, ranker,
  guardrail, metric, dataset, or SDK wiring.
- Write diagnosis and bounded fix plan only when evidence supports it.
- Honor read-only requests. If the user says read-only, dry run, no edits, or
  "do not edit files", do not write `.galileo/` artifacts. Return the RCA
  inline and include a short "Would write" list for any suggested artifact
  paths.

How to install

The exact contents, by fingerprint
mdr add galileo-agent-labs/eval-engineer/eval-diagnose@sha256:40c50e7e3f672f15

The line at the top of this page pins the label git:20260529.4056a23, 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.
