What problem does it solve? Long planning sessions end with conclusions buried in conversation history and lengthy source documents. This Skill compresses what the session landed on into one short briefing file that a user can read in ten minutes and act on, capturing the final proposal in implementation order rather than the argument that led to it. ## Core Features & Use Cases - Session-to-Briefing Compression: Distills the current conversation and existing plan documents into a single Markdown briefing with steps in implementation order. - Decision Tracking: Closes with mandatory sections listing decisions the user still owes and facts not yet verified, so blockers are explicit. - Style Enforcement: Applies the prose:technical-writing skill rules — short active sentences, plain language, no narration of change — with a hard ceiling of roughly 170 lines. - Use Case: After a long architecture discussion about fixing stale mirror data, invoke the skill to produce ./.claude/plans/mirror-refresh-briefing.md containing the agreed steps, open decisions, and unverified assumptions. ## Quick Start Ask the assistant to brief the next steps from this session into a plans file, optionally passing a scope hint or slug for the output filename.
