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
# Retro This skill is coordination-exempt: skip the ai-coord gate for its declared work. If a slash or dollar invocation already placed these instructions in the conversation, follow them directly. In that case, do not invoke this skill again through a skill tool. Review agent work. Propose changes to the agent's environment that improve future runs. The environment includes steering files, skills, automated checks, review guidance, tools, and information access. Do not grade the code or the user's decisions. Success means every candidate has session evidence, a recurrence confidence, and a concrete target. The report orders candidates by severity, or it explains why no change is justified. ## Input - `[session-or-focus]` (optional): the sessions, time window, incident, or theme to review. Without it, review the current session. ## Scope and Authority - Inspect and report by default. Change files only when the user explicitly asks to apply candidates. - Read past transcripts only through agents-introspection. Follow its retrieval, secret-handling, and disclosure rules. ## 1. Resolve the Primary Sessions The primary sessions are the sessions under review. …

How to install
mdr add paulrberg/agent-skills/retro@sha256:28017ccb427c15caThe line at the top of this page pins the label git:20261005.92df3f3, 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.
