What problem does it solve? Development sessions on the Shatterfish project lose context between turns because state lives in chat instead of on disk. This Skill standardizes the end-of-turn handoff so every session ends with updated tracking artifacts and a consistent summary message. ## Core Features & Use Cases - Artifact Updates First: Updates sprint-status.yaml, the story spec file, the GitHub issue, docs/roadmap.md, docs/ideas.md, and the memory note before writing the handoff message. - Standard Message Format: Produces a fixed handoff template covering done items with links, artifacts changed, verification results, incidents, the exact next step, and blocking questions. - Use Case: At the end of a coding session on a Shatterfish story, invoke the handoff to close out the GitHub issue comment, refresh sprint status, and leave a readable summary so the next session can resume without re-reading the whole conversation. ## Quick Start Ask the assistant to wrap up the session and write the handoff for the current story.
