<objective>
Generate a structured SESSION_REPORT.md document capturing session outcomes, work performed, and estimated resource usage. Provides a shareable artifact for post-session review.
</objective>

<purpose>
Generate a post-session summary document capturing work performed, outcomes achieved, and estimated resource usage. Writes SESSION_REPORT.md to .planning/reports/ for human review and stakeholder sharing.
</purpose>

<required_reading>

<step name="gather_session_data">
Collect session data from available sources:

1. **STATE.md** — current phase, milestone, progress, blockers, decisions
2. **Git log** — commits made during this session (last 24h or since last report)
3. **Plan/Summary files** — plans executed, summaries written
4. **ROADMAP.md** — milestone context and phase goals

```bash
# Get recent commits (last 24 hours)
git log --oneline --since="24 hours ago" --no-merges 2>/dev/null || echo "No recent commits"

# Count files changed
git diff --stat HEAD~10 HEAD 2>/dev/null | tail -1 || echo "No diff available"
```

Read `.planning/STATE.md` to get:
- Current milestone and phase
- Progress percentage
- Active blockers
- Recent decisions

Read `.planning/ROADMAP.md` to get milestone name and goals.

Check for existing reports:
```bash
ls -la .planning/reports/SESSION_REPORT*.md 2>/dev/null || echo "No previous reports"
```
</step>

<step name="estimate_usage">
Estimate token usage from observable signals:

- Count of tool calls is not directly available, so estimate from git activity and file operations
- Note: This is an **estimate** — exact token counts require API-level instrumentation not available to hooks

Estimation heuristics:
- Each commit ≈ 1 plan cycle (research + plan + execute + verify)
- Each plan file ≈ 2,000-5,000 tokens of agent context
- Each summary file ≈ 1,000-2,000 tokens generated
- Subagent spawns multiply by ~1.5x per agent type used
</step>

<step name="generate_report">
Create the report directory and file:

```bash
mkdir -p .planning/reports
```

Write `.planning/reports/SESSION_REPORT.md` (or `.planning/reports/YYYYMMDD-session-report.md` if previous reports exist):

```markdown
# GSD Session Report

**Generated:** [timestamp]
**Project:** [from PROJECT.md title or directory name]
**Milestone:** [N] — [milestone name from ROADMAP.md]

---

## Session Summary

**Duration:** [estimated from first to last commit timestamp, or "Single session"]
**Phase Progress:** [from STATE.md]
**Plans Executed:** [count of summaries written this session]
**Commits Made:** [count from git log]

## Work Performed

### Phases Touched
[List phases worked on with brief description of what was done]

### Key Outcomes
[Bullet list of concrete deliverables: files created, features implemented, bugs fixed]

### Decisions Made
[From STATE.md decisions table, if any were added this session]

## Files Changed

[Summary of files modified, created, deleted — from git diff stat]

## Blockers & Open Items

[Active blockers from STATE.md]
[Any TODO items created during session]

## Estimated Resource Usage

| Metric | Estimate |
|--------|----------|
| Commits | [N] |
| Files changed | [N] |
| Plans executed | [N] |
| Subagents spawned | [estimated] |

> **Note:** Token and cost estimates require API-level instrumentation.
> These metrics reflect observable session activity only.
