gsd:execute-plan	Execute a PLAN.md file	[path-to-PLAN.md]	Read Glob Grep Bash Task TodoWrite AskUserQuestion

Execute a single PLAN.md file by spawning a subagent.

Orchestrator stays lean: validate plan, spawn subagent, handle checkpoints, report completion. Subagent loads full execute-plan workflow and handles all execution details.

Context budget: ~15% orchestrator, 100% fresh for subagent.

<execution_context> @~/.claude/get-shit-done/templates/subagent-task-prompt.md </execution_context>

Plan path: $ARGUMENTS

@.planning/STATE.md @.planning/config.json (if exists)

1. **Validate plan exists** - Confirm file at $ARGUMENTS exists - Error if not found: "Plan not found: {path}"

2. Check if already executed

   • Derive SUMMARY path from plan path (replace PLAN.md with SUMMARY.md)
   • If SUMMARY exists: "Plan already executed. SUMMARY: {path}"
   • Offer: re-execute or exit

3. Parse plan identifiers Extract from path like .planning/phases/03-auth/03-02-PLAN.md:

   • phase_number: 03
   • phase_name: auth
   • plan_number: 02
   • plan_path: full path

4. Pre-execution summary (interactive mode only) Check config.json for mode. Skip this step if mode=yolo.

   Parse PLAN.md to extract:

   • objective: First sentence or line from <objective> element
   • task_count: Count of <task elements
   • files: Collect unique file paths from <files> elements within tasks

   Display friendly summary before spawning:

   ════════════════════════════════════════
   EXECUTING: {phase_number}-{plan_number} {phase_name}
   ════════════════════════════════════════
   
   Building: {objective one-liner}
   Tasks: {task_count}
   Files: {comma-separated file list}
   
   Full plan: {plan_path}
   ════════════════════════════════════════
   

   No confirmation needed. Proceed to spawn after displaying.

   In yolo mode, display abbreviated version:

   ⚡ Executing {phase_number}-{plan_number}: {objective one-liner}
   

5. Fill and spawn subagent

   • Fill subagent-task-prompt template with extracted values
   • Spawn: Task(prompt=filled_template, subagent_type="general-purpose")

6. Handle subagent return

   • If contains "## CHECKPOINT REACHED": Execute checkpoint_handling
   • If contains "## PLAN COMPLETE": Verify SUMMARY exists, report success

7. Report completion and offer next steps

   • Show SUMMARY path
   • Show commits from subagent return
   • Route to next action (see <offer_next>)

<offer_next> MANDATORY: Present copy/paste-ready next command.

After plan completes, determine what's next:

Step 1: Count plans vs summaries in current phase

ls -1 .planning/phases/[phase-dir]/*-PLAN.md 2>/dev/null | wc -l
ls -1 .planning/phases/[phase-dir]/*-SUMMARY.md 2>/dev/null | wc -l

Step 2: Route based on counts

Condition	Action
summaries < plans	More plans remain → Route A
summaries = plans	Phase complete → Check milestone (Step 3)

---

Route A: More plans remain in phase

Find next PLAN.md without matching SUMMARY.md. Present:

Plan {phase}-{plan} complete.
Summary: .planning/phases/{phase-dir}/{phase}-{plan}-SUMMARY.md

{Y} of {X} plans complete for Phase {Z}.

---

## ▶ Next Up

**{phase}-{next-plan}: [Plan Name]** — [objective from PLAN.md]

`/gsd:execute-plan .planning/phases/{phase-dir}/{phase}-{next-plan}-PLAN.md`

<sub>`/clear` first → fresh context window</sub>

---

---

Step 3: Check milestone status (only when phase complete)

Read ROADMAP.md. Find current phase number and highest phase in milestone.

Condition	Action
current < highest	More phases → Route B
current = highest	Milestone complete → Route C

---

Route B: Phase complete, more phases remain

## ✓ Phase {Z}: {Name} Complete

All {Y} plans finished.

---

## ▶ Next Up

**Phase {Z+1}: {Name}** — {Goal from ROADMAP.md}

`/gsd:plan-phase {Z+1}`

<sub>`/clear` first → fresh context window</sub>

---

---

Route C: Milestone complete

🎉 MILESTONE COMPLETE!

## ✓ Phase {Z}: {Name} Complete

All {N} phases finished.

---

## ▶ Next Up

`/gsd:complete-milestone`

<sub>`/clear` first → fresh context window</sub>

<checkpoint_handling> When subagent returns with checkpoint:

1. Parse return:

## CHECKPOINT REACHED

**Type:** [human-verify | decision | human-action]
**Plan:** {phase}-{plan}
**Progress:** {completed}/{total} tasks complete

[Checkpoint content]

**Awaiting:** [Resume signal]

2. Present to user: Display the checkpoint content exactly as returned by subagent.

3. Collect response: Wait for user input:

• human-verify: "approved" or description of issues
• decision: option selection
• human-action: "done" when complete

4. Resume subagent:

Task(resume="{agent_id}", prompt="User response: {user_input}")

5. Repeat: Continue handling returns until "## PLAN COMPLETE" or user stops. </checkpoint_handling>

<success_criteria>

• Plan executed (SUMMARY.md created)
• All checkpoints handled
• User informed of completion and next steps </success_criteria>
