Reviews recent work, prompts the user with reflection questions, then distills findings into memory files and retro docs.

Retrospectives

Captures learnings at natural completion points and persists them for future use. This skill is both auto-triggered (EPIC completion hook in swain-design) and manually invocable via /swain-retro.

Invocation modes

Mode	Trigger	Context source
Auto	EPIC transitions to Complete (called by swain-design)	The completed EPIC and its child artifacts
Manual	User runs /swain-retro or /swain retro	Recent work — git log, closed tasks, transitioned artifacts
Scoped	/swain-retro EPIC-NNN or /swain-retro SPEC-NNN	Specific artifact and its related work

Step 1 — Gather context

Collect evidence of what happened during the work period.

For EPIC-scoped retros (auto or scoped)

# Get the EPIC and its children
bash skills/swain-design/scripts/specgraph.sh tree <EPIC-ID>

# Get closed tasks linked to child specs
TK_BIN="$(cd skills/swain-do/bin && pwd)"
export PATH="$TK_BIN:$PATH"
ticket-query '.status == "closed"' 2>/dev/null | grep -l "<EPIC-ID>\|<SPEC-IDs>"

Also read:

• The EPIC's lifecycle table (dates, duration)
• Child SPECs' verification tables (what was proven)
• Any ADRs created during the work
• Git log for commits between EPIC activation and completion dates

For manual (unscoped) retros

# Recent git activity
git log --oneline --since="1 week ago" --no-merges

# Recently closed tasks
TK_BIN="$(cd skills/swain-do/bin && pwd)"
export PATH="$TK_BIN:$PATH"
ticket-query '.status == "closed"' 2>/dev/null | head -20

# Recently transitioned artifacts
bash skills/swain-design/scripts/specgraph.sh status 2>/dev/null

Also check:

• Existing memory files for context on prior patterns
• Previous retro docs in docs/swain-retro/ for recurring themes

Step 2 — Present summary and prompt reflection

Present a concise summary of what was accomplished, then ask targeted reflection questions. Do not auto-generate retro content — the user drives the reflection.

Summary format

Retro scope: {EPIC-NNN title / "recent work"} Period: {start date} — {end date} Artifacts completed: {list} Tasks closed: {count} Key commits: {notable commits}

Reflection questions

Ask these one at a time, waiting for user response between each:

1. What went well? What patterns or approaches worked effectively that we should repeat?
2. What was surprising? Anything unexpected — blockers, shortcuts, scope changes?
3. What would you change? If you could redo this work, what would you do differently?
4. What patterns emerged? Any recurring themes across tasks — tooling friction, design gaps, communication patterns?

Adapt follow-up questions based on user responses. If the user gives brief answers, probe deeper. If they're expansive, move on.

Step 3 — Distill into memory files

After the reflection conversation, create or update memory files:

Feedback memories

For behavioral patterns and process learnings that should guide future agent behavior:

---
name: retro-{topic}
description: {one-line description of the learning}
type: feedback
---

{The pattern or rule}

**Why:** {User's explanation from the retro}
**How to apply:** {When this guidance kicks in}

Write to the project memory directory:

~/.claude/projects/<project-slug>/memory/feedback_retro_{topic}.md

Update MEMORY.md index.

Project memories

For context about ongoing work patterns, team dynamics, or project-specific learnings:

---
name: retro-{topic}
description: {one-line description}
type: project
---

{The fact or observation}

**Why:** {Context from the retro}
**How to apply:** {How this shapes future suggestions}

Rules for memory creation

• Only create memories the user has explicitly validated during the reflection
• Merge with existing memories when the learning extends a prior pattern
• Use absolute dates (from the retro context), not relative
• Maximum 3-5 memory files per retro — distill, don't dump

Step 4 — Write retro document

Create a dated retro doc capturing the full reflection:

mkdir -p docs/swain-retro

File: docs/swain-retro/YYYY-MM-DD-{topic-slug}.md

Retro doc format

# Retro: {title}

**Date:** {YYYY-MM-DD}
**Scope:** {EPIC-NNN title / "recent work"}
**Period:** {start} — {end}

## Summary

{Brief description of what was completed}

## Artifacts

| Artifact | Title | Outcome |
|----------|-------|---------|
| ... | ... | Complete/Abandoned/... |

## Reflection

### What went well
{User's responses, synthesized}

### What was surprising
{User's responses, synthesized}

### What would change
{User's responses, synthesized}

### Patterns observed
{User's responses, synthesized}

## Learnings captured

| Memory file | Type | Summary |
|------------|------|---------|
| feedback_retro_x.md | feedback | ... |
| project_retro_y.md | project | ... |

Step 5 — Update session bookmark

BOOKMARK="$(find . .claude .agents -path '*/swain-session/scripts/swain-bookmark.sh' -print -quit 2>/dev/null)"
bash "$BOOKMARK" "Completed retro for {scope} — {N} learnings captured"

Integration with swain-design

When swain-design transitions an EPIC to Complete, it should invoke this skill:

After completing EPIC transition → invoke swain-retro with the EPIC ID

This is a best-effort hook — if swain-retro is not available or the user declines, the EPIC transition still succeeds. The hook is documented in swain-design's completion rules, not enforced by this skill.

Referencing prior retros

When running a new retro, scan docs/swain-retro/ for prior retros. If patterns recur across multiple retros, call them out explicitly — recurring themes are the most valuable learnings.

ls docs/swain-retro/*.md 2>/dev/null | head -10
