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

1. Memory path is always .groove/memory/
2. Determine date range from $ARGUMENTS:

- week: last 7 days (today - 7) - month: last 30 days - all: all available data - Default if absent: week

1. 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"

1. Mistakes — query the task backend for resolved incidents under "Groove Memory" → "Mistakes":

- beans list --parent <mistakes-epic-id> -t bug -s completed for resolved; -s in-progress for open - Group by title keywords to identify recurring patterns - Count total resolved vs open incidents - If no task backend or no data: note "No incidents recorded yet"

1. Learnings — glob .groove/memory/learned/*.md (exclude signals.md):

- For each file: read and collect dated entries (## YYYY-MM-DD headings) within the date range - Group by topic (filename stem) - Count entries per topic; show the most recent bullet per topic as a sample - If no files: note "No learnings captured yet"

1. Git activity — run git log --oneline --since="<start-date>" to count commits in the period as a proxy for work volume
2. Output retrospective to conversation in this format:

## Groove Retrospective — <period> (<start-date> to <today>)

### Session Ratings
<count> sessions rated | avg: <N>/5 | trend: <up/down/flat or n/a>
<sparkline of ratings if ≥3 data points, e.g. ▂▄█▆▇>

### Mistakes
<N> incidents resolved | <N> open
Top patterns:
- <root cause pattern> (N occurrences)
- ...
(No recurring patterns) if all unique

### Learnings
<N total entries across <M> topics>
- patterns (<N> entries): <most recent bullet>
- anti-patterns (<N> entries): <most recent bullet>
- ...

### Workflow Health
<git commits in period> commits | <1-sentence summary of overall trend>
e.g. "Stable week — ratings above 4, one incident (resolved), 3 new patterns captured."

Sparkline generation

Use block characters to render a simple ratings sparkline:

• 1/5 → ▁, 2/5 → ▂, 3/5 → ▄, 4/5 → ▆, 5/5 → █
• Only show if ≥ 3 ratings in the period

Constraints

• Read only — do not write to any file
• If a data source file is absent, skip that section gracefully with a one-line note
• Parse table rows defensively: skip malformed rows rather than erroring
• Date filtering: match rows where the YYYY-MM-DD date falls within the range; skip rows without a valid date
• Output to conversation only — never write to AGENTS.md or memory files
