Post-mortem / retrospective for a multi-agent run. Run it AFTER a workflow finishes (/run-plan, the spec → plan → implement chain, a Workflow() fan-out, or any batch of sub-agents) to collect how the run actually went and turn it into actionable change. Gathers cost & resource metrics (tokens, cache efficiency, tool calls, durations, agent count, launch order, parallelism), reconstructs qualitative insights (what was hard, what was easy, what context was duplicated, what was missed), and ends with concrete recommendations (improve an agent's brief, pre-fetch a shared file once, merge or split agents, change concurrency). Outputs a full report to chat and appends one trend row to docs/retros/ledger.md. TRIGGER only when explicitly asked: "/workflow-retro", "retro this run", "workflow retrospective", "analyze that multi-agent run", "how did that workflow go". Does NOT cover: running the workflow itself, editing product code, pushing/merging.
