project-retrospective skillA
project-retrospective is agent-read markdown (skill) from belumume/claude-skills: 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 a.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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 | |----------|----------| …
