**Routing by checkpoint type:**

| Checkpoints | Pattern | Execution |
|-------------|---------|-----------|
| None | A (autonomous) | Single subagent: full plan + SUMMARY + commit |
| Verify-only | B (segmented) | Segments between checkpoints. After none/human-verify → SUBAGENT. After decision/human-action → MAIN |
| Decision | C (main) | Execute entirely in main context |

**Pattern A:** init_agent_tracking → spawn Task(subagent_type="gmd-executor", model=executor_model) with prompt: execute plan at [path], autonomous, all tasks + SUMMARY + commit, follow deviation/auth rules, report: plan name, tasks, SUMMARY path, commit hash → track agent_id → wait → update tracking → report.

**Pattern B:** Execute segment-by-segment. Autonomous segments: spawn subagent for assigned tasks only (no SUMMARY/commit). Checkpoints: main context. After all segments: aggregate, create SUMMARY, commit. See segment_execution.

**Pattern C:** Execute in main using standard flow (step name="execute").

Fresh context per subagent preserves peak quality. Main context stays lean.
</step>

<step name="init_agent_tracking">
```bash
if [ ! -f .planning/agent-history.json ]; then
  echo '{"version":"1.0","max_entries":50,"entries":[]}' > .planning/agent-history.json
fi
rm -f .planning/current-agent-id.txt
if [ -f .planning/current-agent-id.txt ]; then
  INTERRUPTED_ID=$(cat .planning/current-agent-id.txt)
  echo "Found interrupted agent: $INTERRUPTED_ID"
fi
```

If interrupted: ask user to resume (Task `resume` parameter) or start fresh.

**Tracking protocol:** On spawn: write agent_id to `current-agent-id.txt`, append to agent-history.json: `{"agent_id":"[id]","task_description":"[desc]","phase":"[phase]","plan":"[plan]","segment":[num|null],"timestamp":"[ISO]","status":"spawned","completion_timestamp":null}`. On completion: status → "completed", set completion_timestamp, delete current-agent-id.txt. Prune: if entries > max_entries, remove oldest "completed" (never "spawned").

Run for Pattern A/B before spawning. Pattern C: skip.
</step>

<step name="segment_execution">
Pattern B only (verify-only checkpoints). Skip for A/C.

1. Parse segment map: checkpoint locations and types
2. Per segment:
   - Subagent route: spawn gmd-executor for assigned tasks only. Prompt: task range, plan path, read full plan for context, execute assigned tasks, track deviations, NO SUMMARY/commit. Track via agent protocol.
   - Main route: execute tasks using standard flow (step name="execute")
3. After ALL segments: aggregate files/deviations/decisions → create SUMMARY.md (incl. the judgment-note duty — see create_summary) → commit → self-check:
   - Verify key-files.created exist on disk with `[ -f ]`
   - Check `git log --oneline --all --grep="{phase}-{plan}"` returns ≥1 commit
   - Append `## Self-Check: PASSED` or `## Self-Check: FAILED` to SUMMARY

   **Known Claude Code bug (classifyHandoffIfNeeded):** If any segment agent reports "failed" with `classifyHandoffIfNeeded is not defined`, this is a Claude Code runtime bug — not a real failure. Run spot-checks; if they pass, treat as successful.




</step>

<step name="load_prompt">
```bash
cat .planning/phases/XX-name/{phase}-{plan}-PLAN.md
```
This IS the execution instructions. Follow exactly. If plan references CONTEXT.md: honor user's vision throughout.

**If plan contains `<interfaces>` block:** These are pre-extracted type definitions and contracts. Use them directly — do NOT re-read the source files to discover types. The planner already extracted what you need.

Deviations are normal — handle via rules below.

1. Read @context files from prompt
2. Per task:
   - `type="auto"`: if `tdd="true"` → TDD execution. Implement with deviation rules + auth gates. Verify done criteria. Commit (see task_commit). Track hash for Summary.
   - `type="checkpoint:*"`: STOP → checkpoint_protocol → wait for user → continue only after confirmation.
3. Run `<verification>` checks
4. Confirm `<success_criteria>` met
5. Document deviations in Summary
</step>

<authentication_gates>

## Authentication Gates

Auth errors during execution are NOT failures — they're expected interaction points.

**Indicators:** "Not authenticated", "Unauthorized", 401/403, "Please run {tool} login", "Set {ENV_VAR}"

**Protocol:**
1. Recognize auth gate (not a bug)
2. STOP task execution
3. Create dynamic checkpoint:human-action with exact auth steps
4. Wait for user to authenticate
5. Verify credentials work
6. Retry original task
7. Continue normally

**Example:** `vercel --yes` → "Not authenticated" → checkpoint asking user to `vercel login` → verify with `vercel whoami` → retry deploy → continue

**In Summary:** Document as normal flow under "## Authentication Gates", not as deviations.

</authentication_gates>

<deviation_rules>

## Deviation Rules

You WILL discover unplanned work. Apply automatically, track all for Summary.

| Rule | Trigger | Action | Permission |
|------|---------|--------|------------|
| **1: Bug** | Broken behavior, errors, wrong queries, type errors, security vulns, race conditions, leaks | Fix → test → verify → track `[Rule 1 - Bug]` | Auto |
| **2: Missing Critical** | Missing essentials: error handling, validation, auth, CSRF/CORS, rate limiting, indexes, logging | Add → test → verify → track `[Rule 2 - Missing Critical]` | Auto |
| **3: Blocking** | Prevents completion: missing deps, wrong types, broken imports, missing env/config/files, circular deps | Fix blocker → verify proceeds → track `[Rule 3 - Blocking]` | Auto |
| **4: Architectural** | Structural change: new DB table, schema change, new service, switching libs, breaking API, new infra | STOP → present decision (below) → track `[Rule 4 - Architectural]` | Ask user |

**Rule 4 format:**
```
⚠️ Architectural Decision Needed

Current task: [task name]
Discovery: [what prompted this]
Proposed change: [modification]
Why needed: [rationale]
Impact: [what this affects]
Alternatives: [other approaches]

Proceed with proposed change? (yes / different approach / defer)
```

**Priority:** Rule 4 (STOP) > Rules 1-3 (auto) > unsure → Rule 4
**Edge cases:** missing validation → R2 | null crash → R1 | new table → R4 | new column → R1/2
**Heuristic:** Affects correctness/security/completion? → R1-3. Maybe? → R4.

</deviation_rules>

<deviation_documentation>

## Documenting Deviations

Summary MUST include deviations section. None? → `## Deviations from Plan\n\nNone - plan executed exactly as written.`

Per deviation: **[Rule N - Category] Title** — Found during: Task X | Issue | Fix | Files modified | Verification | Commit hash

End with: **Total deviations:** N auto-fixed (breakdown). **Impact:** assessment.

</deviation_documentation>

<tdd_plan_execution>
## TDD Execution

For `type: tdd` plans — RED-GREEN-REFACTOR:

1. **Infrastructure** (first TDD plan only): detect project, install framework, config, verify empty suite
2. **RED:** Read `<behavior>` → failing test(s) → run (MUST fail) → commit: `test({phase}-{plan}): add failing test for [feature]`
3. **GREEN:** Read `<implementation>` → minimal code → run (MUST pass) → commit: `feat({phase}-{plan}): implement [feature]`
4. **REFACTOR:** Clean up → tests MUST pass → commit: `refactor({phase}-{plan}): clean up [feature]`

Errors: RED doesn't fail → investigate test/existing feature. GREEN doesn't pass → debug, iterate. REFACTOR breaks → undo.

See `C:/Users/Christopher/.claude/get-magic-done/references/tdd.md` for structure.
</tdd_plan_execution>

<task_commit>
## Task Commit Protocol

After each task (verification passed, done criteria met), commit immediately.

**1. Check:** `git status --short`

**2. Stage individually** (NEVER `git add .` or `git add -A`):
```bash
git add src/api/auth.ts
git add src/types/user.ts
```

**3. Commit type:**

| Type | When | Example |
|------|------|---------|
| `feat` | New functionality | feat(08-02): create user registration endpoint |
| `fix` | Bug fix | fix(08-02): correct email validation regex |
| `test` | Test-only (TDD RED) | test(08-02): add failing test for password hashing |
| `refactor` | No behavior change (TDD REFACTOR) | refactor(08-02): extract validation to helper |
| `perf` | Performance | perf(08-02): add database index |
| `docs` | Documentation | docs(08-02): add API docs |
| `style` | Formatting | style(08-02): format auth module |
| `chore` | Config/deps | chore(08-02): add bcrypt dependency |

**4. Format:** `{type}({phase}-{plan}): {description}` with bullet points for key changes.

**5. Record hash:**
```bash
TASK_COMMIT=$(git rev-parse --short HEAD)
TASK_COMMITS+=("Task ${TASK_NUM}: ${TASK_COMMIT}")
```

</task_commit>

<step name="checkpoint_protocol">
On `type="checkpoint:*"`: automate everything possible first. Checkpoints are for verification/decisions only.

Display: `CHECKPOINT: [Type]` box → Progress {X}/{Y} → Task name → type-specific content → `YOUR ACTION: [signal]`

| Type | Content | Resume signal |
|------|---------|---------------|
| human-verify (90%) | What was built + verification steps (commands/URLs) | "approved" or describe issues |
| decision (9%) | Decision needed + context + options with pros/cons | "Select: option-id" |
| human-action (1%) | What was automated + ONE manual step + verification plan | "done" |

After response: verify if specified. Pass → continue. Fail → inform, wait. WAIT for user — do NOT hallucinate completion.

See C:/Users/Christopher/.claude/get-magic-done/references/checkpoints.md for details.
</step>

<step name="checkpoint_return_for_orchestrator">
When spawned via Task and hitting checkpoint: return structured state (cannot interact with user directly).

**Required return:** 1) Completed Tasks table (hashes + files) 2) Current Task (what's blocking) 3) Checkpoint Details (user-facing content) 4) Awaiting (what's needed from user)

Orchestrator parses → presents to user → spawns fresh continuation with your completed tasks state. You will NOT be resumed. In main context: use checkpoint_protocol above.
</step>

<step name="verification_failure_gate">
If verification fails: STOP. Present: "Verification failed for Task [X]: [name]. Expected: [criteria]. Actual: [result]." Options: Retry | Skip (mark incomplete) | Stop (investigate). If skipped → SUMMARY "Issues Encountered".

<step name="generate_user_setup">
```bash
grep -A 50 "^user_setup:" .planning/phases/XX-name/{phase}-{plan}-PLAN.md | head -50

If user_setup exists: create `{phase}-USER-SETUP.md` using template `C:/Users/Christopher/.claude/get-magic-done/templates/user-setup.md`. Per service: env vars table, account setup checklist, dashboard config, local dev notes, verification commands. Status "Incomplete". Set `USER_SETUP_CREATED=true`. If empty/missing: skip.
</step>

<step name="create_summary">
Create `{phase}-{plan}-SUMMARY.md` at `.planning/phases/XX-name/`. Use `C:/Users/Christopher/.claude/get-magic-done/templates/summary.md`.

**Frontmatter:** phase, plan, subsystem, tags | requires/provides/affects | tech-stack.added/patterns | key-files.created/modified | key-decisions | requirements-completed (**MUST** copy `requirements` array from PLAN.md frontmatter verbatim) | duration ($DURATION), completed ($PLAN_END_TIME date).

Title: `# Phase [X] Plan [Y]: [Name] Summary`

One-liner SUBSTANTIVE: "JWT auth with refresh rotation using jose library" not "Authentication implemented"

Include: duration, start/end times, task count, file count.

**Judgment-note duty (NOTE-01 / D-V184-03)** — this is the Pattern-B/C twin of the gmd-executor `summary_creation` duty (segment subagents write NO SUMMARY → the SUMMARY writer owns the note duty). At SUMMARY time, write judgment notes for the DERIVABLE candidate set — the code entities of this plan's `files_modified` (when in doubt, `code-slice --diff` over the plan's commit range lists them) — wherever a change embodies a non-obvious WHY, a contract change whose caller-compatibility reasoning should outlive the plan, or a gotcha a future verifier must know: `node "$HOME/.claude/get-magic-done/bin/gmd-tools.cjs" code-notes add --anchor "<file#name>" --what-file <tmp> --why-file <tmp> [--regression-file <tmp>] --phase "${PHASE}" --plan "${PLAN}"`. The CLI self-stages the note (`git add -f`) — the metadata commit carries it; notes are reversible own-schema files that NEVER route through landAtom / vault-inbox / the review queue. **Zero notes is a legitimate outcome** — the duty's presence is what is audited, never a note count.

**SESSION-STAMP DUTY (DISC-03):** after writing SUMMARY.md, run `node "$HOME/.claude/get-magic-done/bin/gmd-tools.cjs" vault-telemetry-stamp "<summary path>"` — stamps the telemetry session_id into the SUMMARY frontmatter so read-utilization correlation can join this session's retrievals to THIS artifact; fail-open (always exit 0; silent no-op when telemetry is disabled); never blocks.

Next: more plans → "Ready for {next-plan}" | last → "Phase complete, ready for transition".
