Milestone Summary Workflow

Generate a comprehensive, human-friendly project summary from completed milestone artifacts. Designed for team onboarding — a new contributor can read the output and understand the entire project.

---

Step 1: Resolve Version

VERSION="$ARGUMENTS"

If $ARGUMENTS is empty:

1. Check .planning/STATE.md for current milestone version
2. Check .planning/milestones/ for the latest archived version
3. If neither found, check if .planning/ROADMAP.md exists (project may be mid-milestone)
4. If nothing found: error "No milestone found. Run /gsd:new-project or /gsd:new-milestone first."

Set VERSION to the resolved version (e.g., "1.0").

Step 2: Locate Artifacts

Determine whether the milestone is archived or current:

Archived milestone (.planning/milestones/v{VERSION}-ROADMAP.md exists):

ROADMAP_PATH=".planning/milestones/v${VERSION}-ROADMAP.md"
REQUIREMENTS_PATH=".planning/milestones/v${VERSION}-REQUIREMENTS.md"
AUDIT_PATH=".planning/milestones/v${VERSION}-MILESTONE-AUDIT.md"

Current/in-progress milestone (no archive yet):

ROADMAP_PATH=".planning/ROADMAP.md"
REQUIREMENTS_PATH=".planning/REQUIREMENTS.md"
AUDIT_PATH=".planning/v${VERSION}-MILESTONE-AUDIT.md"

Note: The audit file moves to .planning/milestones/ on archive (per complete-milestone workflow). Check both locations as a fallback.

Always available:

PROJECT_PATH=".planning/PROJECT.md"
RETRO_PATH=".planning/RETROSPECTIVE.md"
STATE_PATH=".planning/STATE.md"

Read all files that exist. Missing files are fine — the summary adapts to what's available.

Step 3: Discover Phase Artifacts

Find all phase directories:

_GSD_SHIM_NAME="gsd-tools.cjs"; _GSD_RUNTIME_ROOT="${RUNTIME_DIR:-$(git rev-parse --show-toplevel 2>/dev/null || pwd)}"; GSD_TOOLS="${_GSD_RUNTIME_ROOT}/gsd-core/bin/${_GSD_SHIM_NAME}"; if [ -f "$GSD_TOOLS" ]; then gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${_GSD_RUNTIME_ROOT}/.claude/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${_GSD_RUNTIME_ROOT}/.claude/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${_GSD_RUNTIME_ROOT}/.codex/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${_GSD_RUNTIME_ROOT}/.codex/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif command -v gsd-tools >/dev/null 2>&1; then GSD_TOOLS="$(command -v gsd-tools)"; gsd_run() { "$GSD_TOOLS" "$@"; }; elif [ -f "$HOME/.claude/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="$HOME/.claude/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${HERMES_HOME:-$HOME/.hermes}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${HERMES_HOME:-$HOME/.hermes}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${CURSOR_CONFIG_DIR:-$HOME/.cursor}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${CURSOR_CONFIG_DIR:-$HOME/.cursor}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${CODEX_HOME:-$HOME/.codex}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${CODEX_HOME:-$HOME/.codex}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${GEMINI_CONFIG_DIR:-$HOME/.gemini}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${GEMINI_CONFIG_DIR:-$HOME/.gemini}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${COPILOT_CONFIG_DIR:-$HOME/.copilot}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${COPILOT_CONFIG_DIR:-$HOME/.copilot}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${WINDSURF_CONFIG_DIR:-$HOME/.codeium/windsurf}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${WINDSURF_CONFIG_DIR:-$HOME/.codeium/windsurf}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${AUGMENT_CONFIG_DIR:-$HOME/.augment}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${AUGMENT_CONFIG_DIR:-$HOME/.augment}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${TRAE_CONFIG_DIR:-$HOME/.trae}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${TRAE_CONFIG_DIR:-$HOME/.trae}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${QWEN_CONFIG_DIR:-$HOME/.qwen}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${QWEN_CONFIG_DIR:-$HOME/.qwen}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${CODEBUDDY_CONFIG_DIR:-$HOME/.codebuddy}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${CODEBUDDY_CONFIG_DIR:-$HOME/.codebuddy}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${CLINE_CONFIG_DIR:-$HOME/.cline}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${CLINE_CONFIG_DIR:-$HOME/.cline}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${GROK_AGENTS_HOME:-$HOME/.agents}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${GROK_AGENTS_HOME:-$HOME/.agents}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${ANTIGRAVITY_CONFIG_DIR:-$HOME/.gemini/antigravity}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${ANTIGRAVITY_CONFIG_DIR:-$HOME/.gemini/antigravity}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${OPENCODE_CONFIG_DIR:-${XDG_CONFIG_HOME:-$HOME/.config}/opencode}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${OPENCODE_CONFIG_DIR:-${XDG_CONFIG_HOME:-$HOME/.config}/opencode}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${KILO_CONFIG_DIR:-${XDG_CONFIG_HOME:-$HOME/.config}/kilo}/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${KILO_CONFIG_DIR:-${XDG_CONFIG_HOME:-$HOME/.config}/kilo}/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; else echo "ERROR: gsd-tools.cjs not found at $GSD_TOOLS and gsd-tools is not on PATH.

gsd_run query init.progress

This returns phase metadata. For each phase in the milestone scope:

• Read {phase_dir}/{padded}-SUMMARY.md if it exists — extract one_liner, accomplishments, decisions
• Read {phase_dir}/{padded}-VERIFICATION.md if it exists — extract status, gaps, deferred items
• Read {phase_dir}/{padded}-CONTEXT.md if it exists — extract key decisions from <decisions> section
• Read {phase_dir}/{padded}-RESEARCH.md if it exists — note what was researched

Track which phases have which artifacts.

If no phase directories exist (empty milestone or pre-build state): skip to Step 5 and generate a minimal summary noting "No phases have been executed yet." Do not error — the summary should still capture PROJECT.md and ROADMAP.md content.

Step 4: Gather Git Statistics

Try each method in order until one succeeds:

Method 1 — Tagged milestone (check first):

git tag -l "v${VERSION}" | head -1

If the tag exists:

git log v${VERSION} --oneline | wc -l
git diff --stat $(git log --format=%H --reverse v${VERSION} | head -1)..v${VERSION}

Method 2 — STATE.md date range (if no tag): Read STATE.md and extract the started_at or earliest session date. Use it as the --since boundary:

git log --oneline --since="<started_at_date>" | wc -l

Method 3 — Earliest phase commit (if STATE.md has no date): Find the earliest .planning/phases/ commit:

git log --oneline --diff-filter=A -- ".planning/phases/" | tail -1

Use that commit's date as the start boundary.

Method 4 — Skip stats (if none of the above work): Report "Git statistics unavailable — no tag or date range could be determined." This is not an error — the summary continues without the Stats section.

Extract (when available):

• Total commits in milestone
• Files changed, insertions, deletions
• Timeline (start date → end date)
• Contributors (from git log authors)

Step 5: Generate Summary Document

Write to .planning/reports/MILESTONE_SUMMARY-v${VERSION}.md:

# Milestone v{VERSION} — Project Summary

**Generated:** {date}
**Purpose:** Team onboarding and project review

---

## 1. Project Overview

{From PROJECT.md: "What This Is", core value proposition, target users}
{If mid-milestone: note which phases are complete vs in-progress}

## 2. Architecture & Technical Decisions

{From CONTEXT.md files across phases: key technical choices}
{From SUMMARY.md decisions: patterns, libraries, frameworks chosen}
{From PROJECT.md: tech stack if documented}

Present as a bulleted list of decisions with brief rationale:
- **Decision:** {what was chosen}
  - **Why:** {rationale from CONTEXT.md}
  - **Phase:** {which phase made this decision}

## 3. Phases Delivered

| Phase | Name | Status | One-Liner |
|-------|------|--------|-----------|
{For each phase: number, name, status (complete/in-progress/planned), one_liner from SUMMARY.md}

## 4. Requirements Coverage

{From REQUIREMENTS.md: list each requirement with status}
- ✅ {Requirement met}
- ⚠️ {Requirement partially met — note gap}
- ❌ {Requirement not met — note reason}

{If MILESTONE-AUDIT.md exists: include audit verdict}

## 5. Key Decisions Log

{Aggregate from all CONTEXT.md <decisions> sections}
{Each decision with: ID, description, phase, rationale}

## 6. Tech Debt & Deferred Items

{From VERIFICATION.md files: gaps found, anti-patterns noted}
{From RETROSPECTIVE.md: lessons learned, what to improve}
{From CONTEXT.md <deferred> sections: ideas parked for later}

## 7. Getting Started

{Entry points for new contributors:}
- **Run the project:** {from PROJECT.md or SUMMARY.md}
- **Key directories:** {from codebase structure}
- **Tests:** {test command from PROJECT.md or CLAUDE.md}
- **Where to look first:** {main entry points, core modules}

---

## Stats

- **Timeline:** {start} → {end} ({duration})
- **Phases:** {count complete} / {count total}
- **Commits:** {count}
- **Files changed:** {count} (+{insertions} / -{deletions})
- **Contributors:** {list}

Step 6: Write and Commit

Overwrite guard: If .planning/reports/MILESTONE_SUMMARY-v${VERSION}.md already exists, ask the user:

"A milestone summary for v{VERSION} already exists. Overwrite it, or view the existing one?" If "view": display existing file and skip to Step 8 (interactive mode). If "overwrite": proceed.

Create the reports directory if needed:

mkdir -p .planning/reports

Write the summary, then commit:

gsd_run query commit "docs(v${VERSION}): generate milestone summary for onboarding" --files \
  ".planning/reports/MILESTONE_SUMMARY-v${VERSION}.md"

Step 7: Present Summary

Display the full summary document inline.

Step 8: Offer Interactive Mode

After presenting the summary:

"Summary written to .planning/reports/MILESTONE_SUMMARY-v{VERSION}.md.

I have full context from the build artifacts. Want to ask anything about the project? Architecture decisions, specific phases, requirements, tech debt — ask away."

If the user asks questions:

• Answer from the artifacts already loaded (CONTEXT.md, SUMMARY.md, VERIFICATION.md, etc.)
• Reference specific files and decisions
• Stay grounded in what was actually built (not speculation)

If the user is done:

• Suggest next steps: /gsd:new-milestone, /gsd:progress, or sharing the summary with the team

Step 9: Update STATE.md

gsd_run query state.record-session "" \
  "Milestone v${VERSION} summary generated" \
  ".planning/reports/MILESTONE_SUMMARY-v${VERSION}.md"
