Structure the output as:

---

Tweetable summary (first line, before everything else):

Week of Mar 1: 47 commits (3 contributors), 3.2k LOC, 38% tests, 12 PRs, peak: 10pm | Streak: 47d

Engineering Retro: [date range]

Summary Table

(from Step 2)

Trends vs Last Retro

(from Step 12, loaded before save — skip if no matching history; in compare mode use Current vs Prior Period from the computed prior window even on the first run). Include the Recommendation follow-through line when Step 12 produced one.

Time & Session Patterns

(from Steps 3-4)

Narrative interpreting what the team-wide patterns mean:

• When the most productive hours are and what drives them
• Whether sessions are getting longer or shorter over time
• Estimated hours per day of active coding (team aggregate)
• Notable patterns: do team members code at the same time or in shifts?

Shipping Velocity

(from Steps 5-7)

Narrative covering:

• Commit type mix and what it reveals
• PR size distribution and what it reveals about shipping cadence
• Fix-chain detection (sequences of fix commits on the same subsystem)
• Version bump discipline

Factory scorecard

(from Step 7.5 when it ran; the table as printed, unavailable (...) lines kept; omit the section when the step was skipped)

Code Quality Signals

• Test LOC ratio trend
• Hotspot analysis (are the same files churning?)
• Greptile signal ratio and trend (if history exists): "Greptile: X% signal (Y valid catches, Z false positives)"

Test Health

• Total test files: N (TEST_FILES_TOTAL)
• Test files changed this period: M (TEST_FILES_CHANGED; not newly added test cases)
• Regression test commits: list the REGRESSION_COMMIT lines (test(qa):, test(design):, and test: coverage commits)
• If prior retro exists and has test_health: show delta "Test count: {last} → {now} (+{delta})"
• If test ratio < 20%: flag as growth area — "100% test coverage is the goal. Tests make vibe coding safe."

Plan Completion

Check review JSONL logs for plan completion data from /ship runs this period:

GSTACK_STATE_ROOT=$(~/.claude/skills/gstack/bin/gstack-paths --get GSTACK_STATE_ROOT); : "${GSTACK_STATE_ROOT:?gstack-paths failed; reinstall with ./setup or /gstack-upgrade}"
setopt +o nomatch 2>/dev/null || true  # zsh compat
SLUG=$(~/.claude/skills/gstack/bin/gstack-slug --get SLUG 2>/dev/null)
cat "$GSTACK_STATE_ROOT"/projects/$SLUG/*-reviews.jsonl 2>/dev/null | grep '"skill":"ship"' | grep '"plan_items_total"' || echo "NO_PLAN_DATA"

If plan completion data exists within the retro time window:

• Count branches shipped with plans (entries that have plan_items_total > 0)
• Compute average completion: sum of plan_items_done / sum of plan_items_total
• Identify most-skipped item category if data supports it

Output:

Plan Completion This Period:
  {N} branches shipped with plans
  Average completion: {X}% ({done}/{total} items)

If no plan data exists, skip this section silently.

Focus & Highlights

(from Step 8)

• Focus score with interpretation
• Ship of the week callout

Shipping Streaks

(from Step 11: team and personal streaks, including broken-streak disclosure)

Shortcut Debt

(from Step 11.5: marker ledger and count, or the clean-ledger statement)

Your Week (personal deep-dive)

(from Step 9, for the current user only)

This is the section the user cares most about. Include:

• Their personal commit count, LOC, test ratio
• Their session patterns and peak hours
• Their focus areas
• Their biggest ship
• What you did well (2-3 specific things anchored in commits)
• Where to level up (1-2 specific, actionable suggestions)

Team Breakdown

(from Step 9, for each teammate — skip if solo repo)

For each teammate (sorted by commits descending), write a section:

[Name]

• What they shipped: 2-3 sentences on their contributions, areas of focus, and commit patterns
• Praise: 1-2 specific things they did well, anchored in actual commits. Be genuine — what would you actually say in a 1:1? Examples:
  • "Cleaned up the entire auth module in 3 small, reviewable PRs — textbook decomposition"
  • "Added integration tests for every new endpoint, not just happy paths"
  • "Fixed the N+1 query that was causing 2s load times on the dashboard"
• Opportunity for growth: 1 specific, constructive suggestion. Frame as investment, not criticism. Examples:
  • "Test coverage on the payment module is at 8% — worth investing in before the next feature lands on top of it"
  • "Most commits land in a single burst — spacing work across the day could reduce context-switching fatigue"
  • "All commits land between 1-4am — sustainable pace matters for code quality long-term"

AI collaboration note: If many commits have Co-Authored-By AI trailers (e.g., Claude, Copilot), note the AI-assisted commit percentage as a team metric. Frame it neutrally — "N% of commits were AI-assisted" — without judgment.

Top 3 Team Wins

Identify the 3 highest-impact things shipped in the window across the whole team. For each:

• What it was
• Who shipped it
• Why it matters (product/architecture impact)

3 Things to Improve

Specific, actionable, anchored in actual commits. Mix personal and team-level suggestions. Phrase as "to get even better, the team could..." These are the items saved as recommendations in the Step 13 snapshot, which the next retro scores for follow-through, so name a concrete file, script or check in each.

3 Habits for Next Week

Small, practical, realistic. Each must be something that takes <5 minutes to adopt. At least one should be team-oriented (e.g., "review each other's PRs same-day").
