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.
