Outcome

.groove/memory/weekly/YYYY-Www.md is created or updated with a roll-up of the week's daily files. Sections cover themes, key outcomes, and learnings — no raw detail duplication.

Acceptance Criteria

• File exists at .groove/memory/weekly/YYYY-Www.md (ISO week format, e.g. 2026-W09)
• Themes section identifies recurring topics from daily entries
• Key outcomes section lists significant completions from the week
• Learnings section synthesises patterns and insights across the week
• Content is rolled up from daily files — not duplicated raw detail

Constraints

• Memory path is always .groove/memory/
• Only run on the last weekday of the week, or when user explicitly requests
• Roll up from that week's daily files in .groove/memory/daily/
• If no daily files exist for the week, note that and exit gracefully
• Use template at skills/groove-utilities-memory-log-weekly/templates/weekly.md for file structure
• If file already exists, update rather than overwrite
