Summarize

This formats a clean summary of completed work that gets streamed directly into Linear. It's meant for the end of a development session when you want to document what got done without manually writing it up. The format is opinionated: collapsible sections for changes and file lists, space for PR links, and support for Linear's profile URL mentions. It won't post anything itself, just outputs markdown that another agent displays. Useful if you're using Claude in a Linear workflow and want consistent session summaries without the busy work.

Work Completed — What was accomplished (1-2 sentences) and key outcome
Key Details — Files modified, important changes, PR link if created
Status — Completion status and any follow-up needed

Format

Aim for 3-5 paragraphs maximum
Use clear, professional language suitable for Linear
Use markdown formatting for readability
