Use when a project needs multi-session retrospective analysis: after milestones, before starting a new phase, when vision drift is suspected, or every 3-5 sessions. Triggers include user saying retro, run a retro, since-last-retro; asks to analyze patterns, recurring mistakes, or correction trends across multiple sessions; says how did we get here or project history in a project-arc context (not single-file diffs or README edits); or notes that MEMORY.md has drifted from what actually happened…
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
# Project Retrospective Analyze a project's session history by dispatching parallel historian agents to read each export, then synthesizing their findings into a structured analysis document. The value is in the **extraction criteria** — domain-specific signals tuned for Claude Code session exports, not generic summarization. ## Modes Two modes, differentiated by **output format** (not historian cost): | Mode | Output | When to Use | |------|--------|-------------| | **full** | Standalone ANALYSIS (superset, safe to delete prior) | Phase transitions, major incidents, no prior retro exists, reset the chain | | **incremental** | Delta UPDATE (references prior retro, never delete prior) | Periodic check-ins (every 3-5 sessions), ongoing projects with an existing retro baseline | Both modes reuse prior historian work when a prior retro exists — only NEW exports get fresh historians. The difference is what the synthesizer produces: a standalone document vs. a delta document. ## Arguments Parse `$ARGUMENTS` to determine scope and mode: | Argument | Behavior | |----------|----------| …

How to install
mdr add belumume/claude-skills/project-retrospective@sha256:5bbae314af2ab19dThe line at the top of this page pins the label git:20260523.4eda55c, 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.
