+description: Execute issue queue tasks sequentially with git commit after each task
+argument-hint: "[--dry-run]"
+---
+
+# Issue Execute (Codex Version)
+
+## Core Principle
+
+**Serial Execution**: Execute tasks ONE BY ONE from the issue queue. Complete each task fully (implement → test → commit) before moving to next. Continue autonomously until ALL tasks complete or queue is empty.
+
+## Execution Flow
+
+```
+INIT: Fetch first task via ccw issue next
+
+WHILE task exists:
+  1. Receive task JSON from ccw issue next
+  2. Execute full lifecycle:
+     - IMPLEMENT: Follow task.implementation steps
+     - TEST: Run task.test commands
+     - VERIFY: Check task.acceptance criteria
+     - COMMIT: Stage files, commit with task.commit.message_template
+  3. Report completion via ccw issue complete <queue_id>
+  4. Fetch next task via ccw issue next
+
+WHEN queue empty:
+  Output final summary
+```
+
+## Step 1: Fetch First Task
+
+Run this command to get your first task:
+
+```bash
+ccw issue next
+```
+
+This returns JSON with the full task definition:
+- `queue_id`: Unique ID for queue tracking (e.g., "Q-001")
+- `issue_id`: Parent issue ID (e.g., "ISSUE-20251227-001")
+- `task`: Full task definition with implementation steps
+- `context`: Relevant files and patterns
+- `execution_hints`: Timing and executor hints
+
+If response contains `{ "status": "empty" }`, all tasks are complete - skip to final summary.
+
+## Step 2: Parse Task Response
+
+Expected task structure:
+
+```json
+{
+  "queue_id": "Q-001",
+  "issue_id": "ISSUE-20251227-001",
+  "solution_id": "SOL-001",
+  "task": {
+    "id": "T1",
+    "title": "Task title",
+    "scope": "src/module/",
+    "action": "Create|Modify|Fix|Refactor",
+    "description": "What to do",
+    "modification_points": [
+      { "file": "path/to/file.ts", "target": "function name", "change": "description" }
+    ],
+    "implementation": [
+      "Step 1: Do this",
+      "Step 2: Do that"
+    ],
+    "test": {
+      "commands": ["npm test -- --filter=xxx"],
+      "unit": "Unit test requirements",
+      "integration": "Integration test requirements (optional)"
+    },
+    "acceptance": [
+      "Criterion 1: Must pass",
+      "Criterion 2: Must verify"
+    ],
+    "commit": {
+      "message_template": "feat(scope): description"
+    }
+  },
+  "context": {
+    "relevant_files": ["path/to/reference.ts"],
+    "patterns": "Follow existing pattern in xxx"
+  }
+}
+```
+
+## Step 3: Execute Task Lifecycle
+
+### Phase A: IMPLEMENT
+
+1. Read all `context.relevant_files` to understand existing patterns
+2. Follow `task.implementation` steps in order
+3. Apply changes to `task.modification_points` files
+4. Follow `context.patterns` for code style consistency
+
+**Output format:**
+```
+## Implementing: [task.title]
+
+**Scope**: [task.scope]
+**Action**: [task.action]
+
+**Steps**:
+1. ✓ [implementation step 1]
+2. ✓ [implementation step 2]
+...
+
+**Files Modified**:
+- path/to/file1.ts
+- path/to/file2.ts
+```
+
+### Phase B: TEST
+
+1. Run all commands in `task.test.commands`
+2. Verify unit tests pass (`task.test.unit`)
+3. Run integration tests if specified (`task.test.integration`)
+
+**If tests fail**: Fix the code and re-run. Do NOT proceed until tests pass.
+
+**Output format:**
+```
+## Testing: [task.title]
+
+**Test Results**:
+- [x] Unit tests: PASSED
+- [x] Integration tests: PASSED (or N/A)
+```
+
+### Phase C: VERIFY
+
+Check all `task.acceptance` criteria are met:
+
+```
+## Verifying: [task.title]
+
+**Acceptance Criteria**:
+- [x] Criterion 1: Verified
+- [x] Criterion 2: Verified
+...
+
+All criteria met: YES
+```
+
+**If any criterion fails**: Go back to IMPLEMENT phase and fix.
+
+### Phase D: COMMIT
+
+After all phases pass, commit the changes:
+
+```bash
+# Stage all modified files
+git add path/to/file1.ts path/to/file2.ts ...
+
+# Commit with task message template
+git commit -m "$(cat <<'EOF'
+[task.commit.message_template]
+
+Queue-ID: [queue_id]
+Issue-ID: [issue_id]
+Task-ID: [task.id]
+EOF
+)"
+```
+
+**Output format:**
+```
+## Committed: [task.title]
+
+**Commit**: [commit hash]
+**Message**: [commit message]
+**Files**: N files changed
+```
+
+## Step 4: Report Completion
+
+After commit succeeds, report to queue system:
+
+```bash
+ccw issue complete [queue_id] --result '{
+  "files_modified": ["path1", "path2"],
+  "tests_passed": true,
+  "acceptance_passed": true,
+  "committed": true,
+  "commit_hash": "[actual hash]",
+  "summary": "[What was accomplished]"
+}'
+```
+
+**If task failed and cannot be fixed:**
+
+```bash
+ccw issue fail [queue_id] --reason "Phase [X] failed: [details]"
+```
+
+## Step 5: Continue to Next Task
+
+Immediately fetch the next task:
+
+```bash
+ccw issue next
+```
+
+**Output progress:**
+```
+✓ [N/M] Completed: [queue_id] - [task.title]
+→ Fetching next task...
+```
+
+**DO NOT STOP.** Return to Step 2 and continue until queue is empty.
+
+## Final Summary
+
+When `ccw issue next` returns `{ "status": "empty" }`:
+
+```markdown
+## Issue Queue Execution Complete
+
+**Total Tasks Executed**: N
+**All Commits**:
+| # | Queue ID | Task | Commit |
+|---|----------|------|--------|
+| 1 | Q-001 | Task title | abc123 |
+| 2 | Q-002 | Task title | def456 |
+
+**Files Modified**:
+- path/to/file1.ts
+- path/to/file2.ts
+
+**Summary**:
+[Overall what was accomplished]
+```
+
+## Execution Rules
+
+1. **Never stop mid-queue** - Continue until queue is empty
+2. **One task at a time** - Fully complete (including commit) before moving on
+3. **Tests MUST pass** - Do not proceed to commit if tests fail
+4. **Commit after each task** - Each task gets its own commit
+5. **Self-verify** - All acceptance criteria must pass before commit
+6. **Report accurately** - Use ccw issue complete/fail after each task
+7. **Handle failures gracefully** - If a task fails, report via ccw issue fail and continue to next
+
+## Error Handling
+
+| Situation | Action |
+|-----------|--------|
+| ccw issue next returns empty | All done - output final summary |
+| Tests fail | Fix code, re-run tests |
+| Verification fails | Go back to implement phase |
+| Git commit fails | Check staging, retry commit |
+| ccw issue complete fails | Log error, continue to next task |
+| Unrecoverable error | Call ccw issue fail, continue to next |
+
+## Start Execution
+
+Begin by running:
+
+```bash
+ccw issue next
+```
+
+Then follow the lifecycle for each task until queue is empty.
