What problem does it solve? Teams lose lessons learned when sessions end without a written record, and older retro-log conventions no longer match the current reporting format. This Skill preserves the mandatory per-session retrospective rule while pointing agents to the current After Action Report format and location. ## Core Features & Use Cases - Supersession pointer: Explains that since 2 Sep 2026 the per-session retro entry is the After Action Report, loaded via the wrap-up skill. - Field mapping table: Maps the four legacy 1.x retro fields (what happened, learning or decision, friction, carried forward) onto the corresponding After Action Report sections. - Placement rules: Directs the report to a comment on the Linear ticket the session worked, with an optional vault copy under 00 handover, and declares retro-log.md files read-only archives. - Use Case: An agent finishing a product work session invokes /product-retro and is routed to wrap-up's aar-template.md to write the mandatory After Action Report as a Linear comment. ## Quick Start Ask the agent to write the retro entry for the session just completed, and it will load wrap-up and produce an After Action Report comment on the ticket.
