msd-core/gsd-core/workflows/plan-milestone-gaps.md

Create all phases necessary to close gaps identified by `/gsd:audit-milestone`. Reads MILESTONE-AUDIT.md, groups gaps into logical phases, creates phase entries in ROADMAP.md, and offers to plan each phase. One command creates all fix phases — no manual `/gsd-add-phase` per gap.

<required_reading> Read all files referenced by the invoking prompt's execution_context before starting. </required_reading>

1. Load Audit Results

# Find the most recent audit file
(ls -t .planning/v*-MILESTONE-AUDIT.md 2>/dev/null || true) | head -1

Parse YAML frontmatter to extract structured gaps:

• gaps.requirements — unsatisfied requirements
• gaps.integration — missing cross-phase connections
• gaps.flows — broken E2E flows

If no audit file exists or has no gaps, error:

No audit gaps found. Run `/gsd:audit-milestone` first.

2. Prioritize Gaps

Group gaps by priority from REQUIREMENTS.md:

Priority	Action
must	Create phase, blocks milestone
should	Create phase, recommended
nice	Ask user: include or defer?

For integration/flow gaps, infer priority from affected requirements.

3. Group Gaps into Phases

Cluster related gaps into logical phases:

Grouping rules:

• Same affected phase → combine into one fix phase
• Same subsystem (auth, API, UI) → combine
• Dependency order (fix stubs before wiring)
• Keep phases focused: 2-4 tasks each

Example grouping:

Gap: DASH-01 unsatisfied (Dashboard doesn't fetch)
Gap: Integration Phase 1→3 (Auth not passed to API calls)
Gap: Flow "View dashboard" broken at data fetch

→ Phase 6: "Wire Dashboard to API"
  - Add fetch to Dashboard.tsx
  - Include auth header in fetch
  - Handle response, update state
  - Render user data

4. Determine Phase Numbers

Find highest existing phase:

_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. Run: npx -y @opengsd/gsd-core@latest --claude --local" >&2; exit 1; fi
# Get sorted phase list, extract last one

New phases continue from there:

• If Phase 5 is highest, gaps become Phase 6, 7, 8...

5. Present Gap Closure Plan

## Gap Closure Plan

**Milestone:** {version}
**Gaps to close:** {N} requirements, {M} integration, {K} flows

### Proposed Phases

**Phase {N}: {Name}**
Closes:
- {REQ-ID}: {description}
- Integration: {from} → {to}
Tasks: {count}

**Phase {N+1}: {Name}**
Closes:
- {REQ-ID}: {description}
- Flow: {flow name}
Tasks: {count}

{If nice-to-have gaps exist:}

### Deferred (nice-to-have)

These gaps are optional. Include them?
- {gap description}
- {gap description}

---

Create these {X} phases? (yes / adjust / defer all optional)

Wait for user confirmation.

6. Update ROADMAP.md

Add new phases to current milestone:

### Phase {N}: {Name}
**Goal:** {derived from gaps being closed}
**Requirements:** {REQ-IDs being satisfied}
**Gap Closure:** Closes gaps from audit

### Phase {N+1}: {Name}
...

7. Update REQUIREMENTS.md Traceability Table (REQUIRED)

For each REQ-ID assigned to a gap closure phase:

• Update the Phase column to reflect the new gap closure phase
• Reset Status to Pending

Reset checked-off requirements the audit found unsatisfied:

• Change [x] → [ ] for any requirement marked unsatisfied in the audit
• Update coverage count at top of REQUIREMENTS.md

# Verify traceability table reflects gap closure assignments
grep -c "Pending" .planning/REQUIREMENTS.md

8. Create Phase Directories

For each new phase (N, N+1, …), resolve the directory name via init.phase-op so the project_code prefix is honoured:

INIT=$(gsd_run query init.phase-op "{NN}")
if [[ "$INIT" == @file:* ]]; then INIT=$(cat "${INIT#@file:}"); fi
expected_phase_dir=$(echo "$INIT" | node -e "process.stdout.write(JSON.parse(require('fs').readFileSync('/dev/stdin','utf8')).expected_phase_dir)")
mkdir -p "${expected_phase_dir}"

Repeat for each gap-closure phase number. This produces {CODE}-{NN}-{slug}/ when project_code is set in .planning/config.json, and {NN}-{slug}/ otherwise — consistent with all other phase-creation paths.

9. Commit Roadmap and Requirements Update

gsd_run query commit "docs(roadmap): add gap closure phases {N}-{M}" --files .planning/ROADMAP.md .planning/REQUIREMENTS.md

10. Offer Next Steps

## ✓ Gap Closure Phases Created

**Phases added:** {N} - {M}
**Gaps addressed:** {count} requirements, {count} integration, {count} flows

---

## ▶ Next Up — [${PROJECT_CODE}] ${PROJECT_TITLE}

**Plan first gap closure phase**

`/clear` then:

`/gsd:plan-phase {N}`

---

**Also available:**
- `/gsd:execute-phase {N}` — if plans already exist
- `cat .planning/ROADMAP.md` — see updated roadmap

---

**After all gap phases complete:**

`/gsd:audit-milestone` — re-audit to verify gaps closed
`/gsd:complete-milestone {version}` — archive when audit passes

How Gaps Become Tasks

Requirement gap → Tasks:

gap:
  id: DASH-01
  description: "User sees their data"
  reason: "Dashboard exists but doesn't fetch from API"
  missing:
    - "useEffect with fetch to /api/user/data"
    - "State for user data"
    - "Render user data in JSX"

becomes:

phase: "Wire Dashboard Data"
tasks:
  - name: "Add data fetching"
    files: [src/components/Dashboard.tsx]
    action: "Add useEffect that fetches /api/user/data on mount"

  - name: "Add state management"
    files: [src/components/Dashboard.tsx]
    action: "Add useState for userData, loading, error states"

  - name: "Render user data"
    files: [src/components/Dashboard.tsx]
    action: "Replace placeholder with userData.map rendering"

Integration gap → Tasks:

gap:
  from_phase: 1
  to_phase: 3
  connection: "Auth token → API calls"
  reason: "Dashboard API calls don't include auth header"
  missing:
    - "Auth header in fetch calls"
    - "Token refresh on 401"

becomes:

phase: "Add Auth to Dashboard API Calls"
tasks:
  - name: "Add auth header to fetches"
    files: [src/components/Dashboard.tsx, src/lib/api.ts]
    action: "Include Authorization header with token in all API calls"

  - name: "Handle 401 responses"
    files: [src/lib/api.ts]
    action: "Add interceptor to refresh token or redirect to login on 401"

Flow gap → Tasks:

gap:
  name: "User views dashboard after login"
  broken_at: "Dashboard data load"
  reason: "No fetch call"
  missing:
    - "Fetch user data on mount"
    - "Display loading state"
    - "Render user data"

becomes:

# Usually same phase as requirement/integration gap
# Flow gaps often overlap with other gap types
