Groove Utilities Memory Retrospective

Pulls together your workflow data from the last week, month, or all time and gives you a readable retrospective: session rating trends with a sparkline, recurring mistake patterns from your task backend, and learnings grouped by topic from your memory files. It's read only and dumps everything to the conversation, so you can review it during standups or end of sprint without touching any files. The format is tight and scannable. Honest take: this is only useful if you're already disciplined about logging sessions in signals.md and capturing learnings in markdown files. If your memory directory is empty, you'll just get a bunch of "no data yet" messages.

Files

groove-utilities-memory-retrospective

Use $ARGUMENTS to specify period: week (default), month, or all.

Outcome

A period retrospective is output to the conversation: session rating trend, recurring mistake patterns, top learnings captured, and a short workflow health summary. No files are written.

Acceptance Criteria

Session ratings trend shown (if learned/signals.md has data)
Mistake patterns summarised (from resolved incidents in task backend)
Top learnings listed by topic (from learned/*.md dated entries)
Workflow health summary: one sentence on overall trend
All output goes to conversation only

Steps

Memory path is always .groove/memory/
Determine date range from $ARGUMENTS:
- week: last 7 days (today - 7)
- month: last 30 days
- all: all available data
- Default if absent: week
Session ratings — read .groove/memory/learned/signals.md if it exists:
- Parse table rows matching the date range: | YYYY-MM-DD | N/5 | context |
- Compute: count, average rating, trend (last 3 vs first 3 if enough data)
- If no data: note "No session ratings recorded yet"
