feat(build): add /build skill — universal TDD-first feature implementation command

Adds a Cursor slash command that implements any feature end-to-end:
deep research → TDD (Red/Green/Refactor) → integration test generation
with device pause gate → external setup checklist → verified PR.

Includes a FEATURE_REGISTRY covering 7 feature types (notifications,
auth, payments, deep links, analytics, storage, camera/media) with
per-type test scenarios, external setup steps, and files-to-touch.
Stack-aware: adapts to architecture, state management, backend,
platforms, and e2e tool from project-brief.yaml.

# Design Spec: /build Skill — Universal Feature Implementation Command
**Date:** 2026-05-14
**Status:** Draft — Awaiting user review
**Scope:** A single Cursor slash command that orchestrates the full feature development lifecycle
---
## 1. Problem Statement
Today, implementing any feature (notifications, auth, payments, etc.) requires the user to manually:
- Specify TDD in the prompt
- Remember to include integration test scenarios
- Know which external services need configuring
- Know which files to touch for their specific stack
- Invoke the right skills in the right order
This leads to inconsistent implementations, missed test scenarios, and forgotten native setup steps.
**Goal:** One command — `/build implement [anything]` — that handles everything from research through PR, following every rule, skill, hook, and architecture pattern defined in the project.
---
## 2. Decision
**Form:** Cursor slash command skill file (`.md.tmpl` inside the generator's template system)
**Scope:** Universal + context-aware (reads `project-brief.yaml` to adapt behavior)
**Integration test gate:** Auto-generate `integration_test/` files + pause for device run
---
## 3. Architecture
### 3.1 File Placement
```
flutter-cursor-templates/
generator/
templates/
skills/
build/
SKILL.md.tmpl ← The skill (single new file)
test/
golden/
bloc-clean-firebase/skills/build/SKILL.md
riverpod-ff-supabase/skills/build/SKILL.md
getx-mvc-rest/skills/build/SKILL.md
```
The generator renders this to `.cursor/skills/build/SKILL.md` in the user's project — same pattern as every other skill.
### 3.2 Template Variables
| Placeholder | Source in project-brief.yaml |
|---|---|
| `{{PROJECT_NAME}}` | `project.name` |
| `{{ARCHITECTURE}}` | `stack.architecture` |
| `{{STATE_MANAGEMENT}}` | `stack.state_management` |
| `{{ROUTING}}` | `stack.routing` |
| `{{BACKEND}}` | `stack.backend` |
| `{{PLATFORMS_LIST}}` | `stack.platforms` |
| `{{CODEGEN_LIST}}` | `stack.codegen` |
| `{{TESTING_DEPTH}}` | `testing.depth` |
| `{{E2E_TOOL}}` | `testing.e2e_tool` |
| `{{FEATURES_LIST}}` | `features.modules` |
| `{{SPECIAL_FEATURES}}` | `features.special` |
| `{{FLAVORS_LIST}}` | `environments.flavors` |
| `{{CICD_TOOL}}` | `environments.cicd` |
| `{{PACKAGE_ID}}` | `project.package` |
Conditional blocks: `{{#if backend_firebase}}`, `{{#if platforms_ios}}`, `{{#if platforms_android}}`, `{{#if codegen_freezed}}`, `{{#if codegen_injectable}}`, `{{#if special_push_notifications}}`, `{{#if special_deep_linking}}`

## 4. The 7 Phases
### Phase 1: Context Loading
1. Read `project-brief.yaml` — extract stack, platforms, existing features
2. Parse user's request → match against FEATURE_REGISTRY keywords
3. Print context summary table (feature type, stack, platforms, rules loaded)
4. If feature already in `features.modules`, confirm extending vs. rebuilding
### Phase 2: Deep Research
1. Enumerate required packages + correct versions for current Flutter stable
2. Build complete file manifest: new files (by architecture pattern) + modified files
3. List all external service configuration required per platform
4. Print research results before touching any file
### Phase 3: TDD Implementation
**Invokes: `superpowers:test-driven-development`**
- **Red:** Write all failing unit + widget tests from FEATURE_REGISTRY scenarios. Run to confirm red. Show actual output.
- **Green:** Implement domain → data → presentation layers. Run tests to green. Show actual output.
- **Refactor:** Clean up per `flutter-core.mdc`. Run `flutter analyze`. Show output.
### Phase 4: Integration Test Generation
1. Create `integration_test/[feature_type]/` directory
2. Generate one test file per logical scenario cluster
3. Each file: standard boilerplate with `IntegrationTestWidgetsFlutterBinding` (or Patrol if `{{E2E_TOOL}} = patrol`)
4. Generate `integration_test/[feature]/README.md` — test matrix with run commands
**PAUSE GATE:** Print table of all integration test files, what they cover, whether hardware is required, and the exact `flutter test` commands. Wait for user to paste device output before Phase 6.
### Phase 5: External Setup Checklist
- Grouped by service/platform (Firebase, iOS, Android, backend)
- iOS/Android: table format — Step | Where | What | How to Verify
- Console steps: numbered checklist with exact menu paths and URLs
### Phase 6: Verification Gate
**Invokes: `superpowers:verification-before-completion`**
Required evidence (real output pasted by user):
- `flutter test test/features/[feature]/ --no-pub` → all tests pass
- `flutter analyze` → no issues
- Integration test device output from Phase 4
- `lefthook run pre-commit` → all hooks pass
If any failure: invoke `superpowers:systematic-debugging` before retrying.
### Phase 7: PR Preparation
**Invokes: `superpowers:finishing-a-development-branch`**
- Conventional commit: `feat([feature_type]): implement [feature] end-to-end`
- PR description: what built, test count, integration test matrix, external setup status
- CI/CD advice for `{{CICD_TOOL}}` (secret scoping per flavor)

## 5. FEATURE_REGISTRY
Seven feature types with full metadata:
| Feature Type | Keywords (sample) | Packages | Integration Test Scenarios |
|---|---|---|---|
| `notifications` | notification, push, FCM, APNs | firebase_messaging, flutter_local_notifications | foreground/background/killed receipt, tap redirect in all 3 states, payload parsing |
| `auth` | login, sign in, biometric, OAuth, JWT | firebase_auth, local_auth, flutter_secure_storage | full login flow, biometric + fallback, token refresh, cold start with session |
| `payments` | payment, Stripe, IAP, checkout | flutter_stripe, purchases_flutter | test-card checkout, 3DS, Apple/Google Pay, subscription restore |
| `deep_links` | deep link, universal link, app link | app_links, go_router | cold/background/foreground link handling, auth-guarded routes |
| `analytics` | analytics, event, tracking, screen view | firebase_analytics, mixpanel_flutter | event triggered on action, screen view on nav, opt-out disables tracking |
| `storage` | file upload, Firebase Storage, Hive, Isar | firebase_storage, isar, drift | upload + retrieve, offline cache, background upload restore |
| `camera_media` | camera, photo, QR, barcode, video | camera, image_picker, mobile_scanner | photo capture, gallery pick, QR decode, permission denied UI |
Each entry also specifies: `rules_to_load`, `files_to_touch` (new + modified), `external_setup` (per service/platform), `unit_test_scenarios`, `widget_test_scenarios`.

## 6. Integration Test Template Structure
```dart
// integration_test/[feature]/[scenario]_test.dart
// Generated by /build — {{PROJECT_NAME}}
// Run: flutter test integration_test/[feature]/[scenario]_test.dart -d <device_id>
import 'package:flutter_test/flutter_test.dart';
import 'package:integration_test/integration_test.dart';
import 'package:{{PACKAGE_ID}}/main.dart' as app;
void main() {
IntegrationTestWidgetsFlutterBinding.ensureInitialized();
group('[FeatureType] — [Scenario Name]', () {
setUp(() async { /* seed state / reset storage */ });
tearDown(() async { /* cleanup */ });
testWidgets(
'given [precondition], when [action], then [expected outcome]',
(tester) async {
app.main();
await tester.pumpAndSettle();
// test body
},
);
});
}
```
For `{{E2E_TOOL}} = patrol`: imports swap to `package:patrol`, uses `$` Patrol selector syntax.

## 8. Cross-Skill Orchestration
The `/build` skill orchestrates existing skills internally:
- Invokes `/scaffold-feature` patterns to create the initial file skeleton (Phase 3b)
- Borrows `/generate-tests` naming and structure conventions (Phase 3a)
- Invokes `/generate-api-client` if `api_docs.format != none` and feature needs API (Phase 2)
- References `/deploy` checklist for flavor-scoped secret handling (Phase 7)
---
## 9. Rules Applied Every Phase
Always active (no conditional):
- `.cursor/rules/flutter-core.mdc`
- `.cursor/rules/security-standards.mdc`
- `.cursor/rules/project-context.mdc`
- Feature-type rules from `FEATURE_REGISTRY.rules_to_load`
---
## 10. Enhancements / Out of Scope for V1
- Reference project URL fetching and pattern extraction (Phase 1) — included in V1
- Multi-feature requests spanning 2+ feature types — detect and prompt decomposition
- Automatic CI secret rotation advice — Phase 7, advisory only
- Web platform integration test support — flagged as TODO in generated README
- Visual companion for architecture diagrams — post-V1
---
## 11. Verification
End-to-end test of the skill:
1. Run `cursor_gen --wizard` on a test project → choose `bloc/clean/firebase` stack
2. Confirm `.cursor/skills/build/SKILL.md` is generated
3. In Cursor, type `/build implement notification module end-to-end`
4. Verify Phase 1 prints correct context table from project-brief.yaml
5. Verify Phase 3 tests are red before implementation, green after
6. Verify Phase 4 generates `integration_test/notifications/` with 10 test files
7. Verify Phase 5 checklist lists Firebase Console + APNs steps
8. Verify Phase 6 requires real output before proceeding
9. Run golden tests: `dart test test/generator_test.dart` — all stacks must match golden SKILL.md

## Phase 1: Context Loading
**When the user types `/build <request>`, do the following before writing a single line of code:**
1. Read `project-brief.yaml` from the repo root. Extract and hold in context:
- `stack.state_management` → **{{STATE_MGMT_RAW}}**
- `stack.architecture` → **{{ARCH_RAW}}**
- `stack.routing` → **{{ROUTING_RAW}}**
- `stack.backend` → **{{BACKENDS_LIST}}**
- `stack.platforms` → **{{PLATFORMS_LIST}}**
- `stack.codegen` → **{{CODEGEN_LIST}}**
- `testing.depth` → **{{TESTING_DEPTH}}**
- `testing.e2e_tool` → **{{E2E_TOOL}}**
- `features.modules` (existing features) → **{{FEATURES_LIST}}**
- `features.special` → **{{SPECIAL_FEATURES}}**
- `environments.flavors` → **{{FLAVORS_LIST}}**
- `environments.cicd` → **{{CICD_RAW}}**
2. Parse the user's free-text request. Match against `FEATURE_REGISTRY` keywords using longest-match. Multiple types are allowed if the request spans features.
3. Load `.cursor/rules/` files listed under `rules_to_load` for the matched feature type.
4. If the user's message contains a URL or GitHub repo reference, fetch and index it for pattern reference.
5. Check `features.modules` — if the feature already exists in the list, ask: "This feature is already listed in project-brief.yaml. Building additional capability on top of it? (y/n)"
6. Print the context summary table before proceeding:
```
| Field | Value |
|------------------|------------------------------|
| Feature type | [detected type] |
| State management | {{STATE_MANAGEMENT}} |
| Architecture | {{ARCHITECTURE}} |
| Backend | {{BACKEND}} |
| Platforms | {{PLATFORMS_LIST}} |
| E2E tool | {{E2E_TOOL}} |
| Rules loaded | [list from rules_to_load] |
| Existing modules | {{FEATURES_LIST}} |
```
---
## Phase 2: Deep Research
**Before touching any file, print the full research output.**
1. From the FEATURE_REGISTRY, enumerate all `pub_packages` for the detected type. For each, determine the correct version compatible with current Flutter stable (`flutter --version`). Print the full `pubspec.yaml` additions.
2. Build the complete file manifest, adapting to `{{ARCHITECTURE}}`:
**For {{ARCHITECTURE}} ({{ARCH_RAW}}):**
- `clean`: expand each feature layer explicitly → `domain/entities/`, `domain/repositories/`, `domain/usecases/`, `data/models/`, `data/datasources/`, `data/repositories/`, `presentation/`
- `feature_first`: `[feature]/[feature]_screen.dart`, `[feature]_provider.dart` or `[feature]_bloc.dart`, `[feature]_repository.dart`, `[feature]_model.dart`, `widgets/`
- `mvc`: `[feature]/model/`, `[feature]/view/`, `[feature]/controller/`
**State management file naming ({{STATE_MANAGEMENT}} / {{STATE_MGMT_RAW}}):**
- `bloc`: `[feature]_bloc.dart`, `[feature]_event.dart`, `[feature]_state.dart`
- `riverpod`: `[feature]_provider.dart`, `[feature]_notifier.dart`
- `getx`: `[feature]_controller.dart`, `[feature]_binding.dart`
3. List all modified files from `files_to_touch.modified` — show exactly what change goes in each file.
4. List all external service configuration required per platform (from `external_setup`). Only show platforms present in `{{PLATFORMS_LIST}}`.
5. Print research results in this format:
```
## Research Results
### Packages to add to pubspec.yaml
- [package_name]: ^[version]
### Files to create ({{ARCHITECTURE}} / {{STATE_MANAGEMENT}})
lib/features/[name]/... (full list)
### Files to modify
[file_path] — [what changes]
### External services requiring configuration
- [Service] ([platform]) — [what to do]
```
Do not touch any file until the user has seen this output.

## Phase 3: TDD Implementation
> **Invoke skill: `superpowers:test-driven-development`**
Follow Red → Green → Refactor strictly. Show actual terminal output at each step.
### Step 3a — Red: Write all failing tests first
1. Mirror the feature directory under `test/features/[feature]/`.
2. Write unit tests for **every scenario** in `FEATURE_REGISTRY.unit_test_scenarios` for the detected type.
3. Write widget tests for **every scenario** in `FEATURE_REGISTRY.widget_test_scenarios`.
4. Use `mocktail` for all dependencies.
5. Test naming convention: `'given [precondition], when [action], then [expected outcome]'`
6. Use the state management test pattern for **{{STATE_MANAGEMENT}}**:
```
{{TEST_PATTERN}}
```
7. Run and confirm red:
```
flutter test test/features/[feature]/ --no-pub
```
**Paste the actual output here before proceeding.**
### Step 3b — Green: Implement
1. Create domain entities and repository interfaces.
2. Create data-layer implementations wiring to `{{BACKEND}}`.
3. Create presentation layer using **{{STATE_MANAGEMENT}}** patterns.
4. Register in DI container — follow `{{ARCH_IMPORT_RULES}}`.
5. Wire the route in `{{ROUTING}}` router.
6. If `{{CODEGEN_LIST}}` is not `none`: run `dart run build_runner build --delete-conflicting-outputs` after adding models.
7. Run tests and confirm green:
```
flutter test test/features/[feature]/ --no-pub
```
**Paste the actual output here before proceeding.**
### Step 3c — Refactor
1. Review for duplication, naming, and layer boundary violations per `.cursor/rules/flutter-core.mdc`.
2. Run and confirm clean:
```
flutter analyze
```
**Paste the actual output here before proceeding.**
3. Run tests once more to confirm still green.
---
## Phase 4: Integration Test Generation
**Generate `integration_test/[feature_type]/` before asking the user to run anything.**
### Integration test file structure
Each test file follows this template:
```dart
// integration_test/[feature]/[scenario]_test.dart
// Generated by /build — {{PROJECT_NAME}}
// Feature: [feature_type] | Scenario: [scenario_name]
// Run with: flutter test integration_test/[feature]/[scenario]_test.dart -d <device_id>
import 'package:flutter_test/flutter_test.dart';
import 'package:integration_test/integration_test.dart';
import 'package:{{PACKAGE_ID}}/main.dart' as app;

Create one file per logical scenario cluster from `FEATURE_REGISTRY.integration_test_scenarios`.
Also generate `integration_test/[feature]/README.md` with the full test matrix and run commands.
### PAUSE GATE — user must run on device
After generating all files, print this table and **stop**. Wait for the user to paste device output before Phase 6.
```
## ACTION REQUIRED — Run Integration Tests on Real Device
| File | Covers | Requires Hardware |

## Phase 5: External Setup Checklist
**Print before asking the user to verify anything. Group by service/platform. Only show sections for platforms in `{{PLATFORMS_LIST}}`.**
### Format for console/service steps (numbered list):
```markdown
### Firebase (backend: {{BACKEND}})
- [ ] 1. Open Firebase Console → [exact menu path]
- [ ] 2. [Specific action]
- [ ] 3. Download updated config file → place at [exact path]
```
### Format for native platform steps (table):
```markdown
### iOS Setup
| Step | Where | What | How to Verify |
|------|-------|------|---------------|

## Phase 1: Context Loading
**When the user types `/build <request>`, do the following before writing a single line of code:**
1. Read `project-brief.yaml` from the repo root. Extract and hold in context:
- `stack.state_management`**bloc**
- `stack.architecture`**clean**
- `stack.routing`**gorouter**
- `stack.backend`**firebase**
- `stack.platforms`**ios, android**
- `stack.codegen`**freezed**
- `testing.depth`**unit_widget**
- `testing.e2e_tool`**patrol**
- `features.modules` (existing features) → **auth, home, products**
- `features.special`****
- `environments.flavors`**dev, prod**
- `environments.cicd`**github_actions**
2. Parse the user's free-text request. Match against `FEATURE_REGISTRY` keywords using longest-match. Multiple types are allowed if the request spans features.
3. Load `.cursor/rules/` files listed under `rules_to_load` for the matched feature type.
4. If the user's message contains a URL or GitHub repo reference, fetch and index it for pattern reference.
5. Check `features.modules` — if the feature already exists in the list, ask: "This feature is already listed in project-brief.yaml. Building additional capability on top of it? (y/n)"
6. Print the context summary table before proceeding:
```
| Field | Value |
|------------------|------------------------------|
| Feature type | [detected type] |
| State management | BLoC / Cubit |
| Architecture | Clean Architecture |
| Backend | Firebase |
| Platforms | ios, android |
| E2E tool | patrol |
| Rules loaded | [list from rules_to_load] |
| Existing modules | auth, home, products |
```
---
## Phase 2: Deep Research
**Before touching any file, print the full research output.**
1. From the FEATURE_REGISTRY, enumerate all `pub_packages` for the detected type. For each, determine the correct version compatible with current Flutter stable (`flutter --version`). Print the full `pubspec.yaml` additions.
2. Build the complete file manifest, adapting to `Clean Architecture`:
**For Clean Architecture (clean):**
- `clean`: expand each feature layer explicitly → `domain/entities/`, `domain/repositories/`, `domain/usecases/`, `data/models/`, `data/datasources/`, `data/repositories/`, `presentation/`
- `feature_first`: `[feature]/[feature]_screen.dart`, `[feature]_provider.dart` or `[feature]_bloc.dart`, `[feature]_repository.dart`, `[feature]_model.dart`, `widgets/`
- `mvc`: `[feature]/model/`, `[feature]/view/`, `[feature]/controller/`
**State management file naming (BLoC / Cubit / bloc):**
- `bloc`: `[feature]_bloc.dart`, `[feature]_event.dart`, `[feature]_state.dart`
- `riverpod`: `[feature]_provider.dart`, `[feature]_notifier.dart`
- `getx`: `[feature]_controller.dart`, `[feature]_binding.dart`
3. List all modified files from `files_to_touch.modified` — show exactly what change goes in each file.
4. List all external service configuration required per platform (from `external_setup`). Only show platforms present in `ios, android`.
5. Print research results in this format:
```
## Research Results
### Packages to add to pubspec.yaml
- [package_name]: ^[version]
### Files to create (Clean Architecture / BLoC / Cubit)
lib/features/[name]/... (full list)
### Files to modify
[file_path] — [what changes]
### External services requiring configuration
- [Service] ([platform]) — [what to do]
```
Do not touch any file until the user has seen this output.
---
## Phase 3: TDD Implementation
> **Invoke skill: `superpowers:test-driven-development`**
Follow Red → Green → Refactor strictly. Show actual terminal output at each step.
### Step 3a — Red: Write all failing tests first
1. Mirror the feature directory under `test/features/[feature]/`.
2. Write unit tests for **every scenario** in `FEATURE_REGISTRY.unit_test_scenarios` for the detected type.
3. Write widget tests for **every scenario** in `FEATURE_REGISTRY.widget_test_scenarios`.
4. Use `mocktail` for all dependencies.
5. Test naming convention: `'given [precondition], when [action], then [expected outcome]'`
6. Use the state management test pattern for **BLoC / Cubit**:
```
blocTest<MyCubit, MyState>(description, build: () => MyCubit(), act: (c) => c.method(), expect: () => [MyState()])
```
7. Run and confirm red:
```
flutter test test/features/[feature]/ --no-pub
```
**Paste the actual output here before proceeding.**
### Step 3b — Green: Implement
1. Create domain entities and repository interfaces.
2. Create data-layer implementations wiring to `Firebase`.
3. Create presentation layer using **BLoC / Cubit** patterns.
4. Register in DI container — follow `- presentation/ MUST NOT import from data/
- domain/ MUST NOT import from data/ or presentation/
- data/ CAN import from domain/ (implements interfaces)
- Use dependency injection to invert data → domain dependency`.
5. Wire the route in `GoRouter` router.
6. If `freezed` is not `none`: run `dart run build_runner build --delete-conflicting-outputs` after adding models.
7. Run tests and confirm green:
```
flutter test test/features/[feature]/ --no-pub
```
**Paste the actual output here before proceeding.**
### Step 3c — Refactor
1. Review for duplication, naming, and layer boundary violations per `.cursor/rules/flutter-core.mdc`.
2. Run and confirm clean:
```
flutter analyze
```
**Paste the actual output here before proceeding.**
3. Run tests once more to confirm still green.
---
## Phase 4: Integration Test Generation
**Generate `integration_test/[feature_type]/` before asking the user to run anything.**
### Integration test file structure
Each test file follows this template:
```dart
// integration_test/[feature]/[scenario]_test.dart
// Generated by /build — TestApp
// Feature: [feature_type] | Scenario: [scenario_name]
// Run with: flutter test integration_test/[feature]/[scenario]_test.dart -d <device_id>
import 'package:flutter_test/flutter_test.dart';
import 'package:integration_test/integration_test.dart';
import 'package:com.test.testapp/main.dart' as app;
void main() {
IntegrationTestWidgetsFlutterBinding.ensureInitialized();
group('[FeatureType] — [Scenario Name]', () {
setUp(() async {
// Seed state / configure mocks / reset storage
});
tearDown(() async {
// Cleanup
});
testWidgets(
'given [precondition], when [action], then [expected outcome]',
(tester) async {
app.main();
await tester.pumpAndSettle();
// test body
},
);
});
}
```
**For `patrol` (patrol):** swap `flutter_test` imports for `package:patrol` and use Patrol's `$` NativeAutomator selector syntax.
### Files to generate
Create one file per logical scenario cluster from `FEATURE_REGISTRY.integration_test_scenarios`.
Also generate `integration_test/[feature]/README.md` with the full test matrix and run commands.
### PAUSE GATE — user must run on device
After generating all files, print this table and **stop**. Wait for the user to paste device output before Phase 6.
```
## ACTION REQUIRED — Run Integration Tests on Real Device
| File | Covers | Requires Hardware |
|------|--------|------------------|
| integration_test/[feature]/[scenario]_test.dart | [what it covers] | Yes/No |
...
Run on iOS:

Paste the output here to continue.
```
---
## Phase 5: External Setup Checklist
**Print before asking the user to verify anything. Group by service/platform. Only show sections for platforms in `ios, android`.**
### Format for console/service steps (numbered list):
```markdown

- [ ] 1. Open Firebase Console → [exact menu path]
- [ ] 2. [Specific action]
- [ ] 3. Download updated config file → place at [exact path]

## Phase 1: Context Loading
**When the user types `/build <request>`, do the following before writing a single line of code:**
1. Read `project-brief.yaml` from the repo root. Extract and hold in context:
- `stack.state_management`**riverpod**
- `stack.architecture`**feature_first**
- `stack.routing`**gorouter**
- `stack.backend`**supabase**
- `stack.platforms`**ios, android, web**
- `stack.codegen`**freezed, json_serializable**
- `testing.depth`**unit_widget**
- `testing.e2e_tool`**patrol**
- `features.modules` (existing features) → **auth, tasks, profile**
- `features.special`****
- `environments.flavors`**dev, prod**
- `environments.cicd`**github_actions**
2. Parse the user's free-text request. Match against `FEATURE_REGISTRY` keywords using longest-match. Multiple types are allowed if the request spans features.
3. Load `.cursor/rules/` files listed under `rules_to_load` for the matched feature type.
4. If the user's message contains a URL or GitHub repo reference, fetch and index it for pattern reference.
5. Check `features.modules` — if the feature already exists in the list, ask: "This feature is already listed in project-brief.yaml. Building additional capability on top of it? (y/n)"
6. Print the context summary table before proceeding:
```
| Field | Value |
|------------------|------------------------------|
| Feature type | [detected type] |
| State management | Riverpod |
| Architecture | Feature-First |
| Backend | Supabase |
| Platforms | ios, android, web |
| E2E tool | patrol |
| Rules loaded | [list from rules_to_load] |
| Existing modules | auth, tasks, profile |
```
---
## Phase 2: Deep Research
**Before touching any file, print the full research output.**
1. From the FEATURE_REGISTRY, enumerate all `pub_packages` for the detected type. For each, determine the correct version compatible with current Flutter stable (`flutter --version`). Print the full `pubspec.yaml` additions.
2. Build the complete file manifest, adapting to `Feature-First`:
**For Feature-First (feature_first):**
- `clean`: expand each feature layer explicitly → `domain/entities/`, `domain/repositories/`, `domain/usecases/`, `data/models/`, `data/datasources/`, `data/repositories/`, `presentation/`
- `feature_first`: `[feature]/[feature]_screen.dart`, `[feature]_provider.dart` or `[feature]_bloc.dart`, `[feature]_repository.dart`, `[feature]_model.dart`, `widgets/`
- `mvc`: `[feature]/model/`, `[feature]/view/`, `[feature]/controller/`
**State management file naming (Riverpod / riverpod):**
- `bloc`: `[feature]_bloc.dart`, `[feature]_event.dart`, `[feature]_state.dart`
- `riverpod`: `[feature]_provider.dart`, `[feature]_notifier.dart`
- `getx`: `[feature]_controller.dart`, `[feature]_binding.dart`
3. List all modified files from `files_to_touch.modified` — show exactly what change goes in each file.
4. List all external service configuration required per platform (from `external_setup`). Only show platforms present in `ios, android, web`.
5. Print research results in this format:
```
## Research Results
### Packages to add to pubspec.yaml
- [package_name]: ^[version]
### Files to create (Feature-First / Riverpod)
lib/features/[name]/... (full list)
### Files to modify
[file_path] — [what changes]
### External services requiring configuration
- [Service] ([platform]) — [what to do]
```
Do not touch any file until the user has seen this output.
---
## Phase 3: TDD Implementation
> **Invoke skill: `superpowers:test-driven-development`**
Follow Red → Green → Refactor strictly. Show actual terminal output at each step.
### Step 3a — Red: Write all failing tests first
1. Mirror the feature directory under `test/features/[feature]/`.
2. Write unit tests for **every scenario** in `FEATURE_REGISTRY.unit_test_scenarios` for the detected type.
3. Write widget tests for **every scenario** in `FEATURE_REGISTRY.widget_test_scenarios`.
4. Use `mocktail` for all dependencies.
5. Test naming convention: `'given [precondition], when [action], then [expected outcome]'`
6. Use the state management test pattern for **Riverpod**:
```
final container = ProviderContainer(overrides: [myProvider.overrideWithValue(mockValue)]); addTearDown(container.dispose);
```
7. Run and confirm red:
```
flutter test test/features/[feature]/ --no-pub
```
**Paste the actual output here before proceeding.**
### Step 3b — Green: Implement
1. Create domain entities and repository interfaces.
2. Create data-layer implementations wiring to `Supabase`.
3. Create presentation layer using **Riverpod** patterns.
4. Register in DI container — follow `- features/auth/ MUST NOT import from features/home/ etc.
- Shared code lives in core/ or shared/ only
- Each feature is self-contained: screen + provider + model + repo`.
5. Wire the route in `GoRouter` router.
6. If `freezed, json_serializable` is not `none`: run `dart run build_runner build --delete-conflicting-outputs` after adding models.
7. Run tests and confirm green:
```
flutter test test/features/[feature]/ --no-pub
```
**Paste the actual output here before proceeding.**
### Step 3c — Refactor
1. Review for duplication, naming, and layer boundary violations per `.cursor/rules/flutter-core.mdc`.
2. Run and confirm clean:
```
flutter analyze
```
**Paste the actual output here before proceeding.**
3. Run tests once more to confirm still green.
---
## Phase 4: Integration Test Generation
**Generate `integration_test/[feature_type]/` before asking the user to run anything.**
### Integration test file structure
Each test file follows this template:
```dart
// integration_test/[feature]/[scenario]_test.dart
// Generated by /build — TaskFlow
// Feature: [feature_type] | Scenario: [scenario_name]
// Run with: flutter test integration_test/[feature]/[scenario]_test.dart -d <device_id>
import 'package:flutter_test/flutter_test.dart';
import 'package:integration_test/integration_test.dart';
import 'package:com.test.taskflow/main.dart' as app;
void main() {
IntegrationTestWidgetsFlutterBinding.ensureInitialized();
group('[FeatureType] — [Scenario Name]', () {
setUp(() async {
// Seed state / configure mocks / reset storage
});
tearDown(() async {
// Cleanup
});
testWidgets(
'given [precondition], when [action], then [expected outcome]',
(tester) async {
app.main();
await tester.pumpAndSettle();
// test body
},
);
});
}
```
**For `patrol` (patrol):** swap `flutter_test` imports for `package:patrol` and use Patrol's `$` NativeAutomator selector syntax.
### Files to generate
Create one file per logical scenario cluster from `FEATURE_REGISTRY.integration_test_scenarios`.
Also generate `integration_test/[feature]/README.md` with the full test matrix and run commands.
### PAUSE GATE — user must run on device
After generating all files, print this table and **stop**. Wait for the user to paste device output before Phase 6.
```
## ACTION REQUIRED — Run Integration Tests on Real Device
| File | Covers | Requires Hardware |
|------|--------|------------------|
| integration_test/[feature]/[scenario]_test.dart | [what it covers] | Yes/No |
...
Run on iOS:
flutter test integration_test/[feature]/ -d <your_ios_device_id>
Run on Android:
flutter test integration_test/[feature]/ -d <your_android_device_id>
Paste the output here to continue.
```
---
## Phase 5: External Setup Checklist
**Print before asking the user to verify anything. Group by service/platform. Only show sections for platforms in `ios, android, web`.**
### Format for console/service steps (numbered list):
```markdown
### Firebase (backend: Supabase)
- [ ] 1. Open Firebase Console → [exact menu path]
- [ ] 2. [Specific action]
- [ ] 3. Download updated config file → place at [exact path]
```
### Format for native platform steps (table):
```markdown
### iOS Setup
| Step | Where | What | How to Verify |
|------|-------|------|---------------|
| [Step name] | [Xcode location / file path] | [Exact change] | [Verification method] |
```
```markdown
### Android Setup
- [ ] 1. Open `android/app/src/main/AndroidManifest.xml`
- Add: `<uses-permission android:name="[permission]"/>`
- [ ] 2. [Next step with exact value]
```
### Flavor scoping note (flavors: dev, prod)
Config files and API keys must be scoped per flavor. Never place production keys in `dev` flavor files. Follow the pattern established in `.cursor/rules/` for flavor-based configuration.
---
## Phase 6: Verification Gate
> **Invoke skill: `superpowers:verification-before-completion`**
**Do not claim completion without pasting real output for every item below.**
```
VERIFICATION REQUIRED — paste real output for each:
[ ] flutter test test/features/[feature]/ --no-pub
Required: "All N tests passed."
[ ] flutter analyze
Required: "No issues found!"
[ ] Integration test device output (from Phase 4 pause gate)
Required: actual device test output
[ ] lefthook run pre-commit
Required: all hooks passed
```
If any check fails: invoke `superpowers:systematic-debugging` to diagnose before retrying.
Do not proceed to Phase 7 until all four checks are green.
---
## Phase 7: PR Preparation
> **Invoke skill: `superpowers:finishing-a-development-branch`**
1. **Commit message** (conventional commits format):
```
feat([feature_type]): implement [feature] end-to-end
```
2. **PR description template:**
```markdown
## What
[One sentence: what feature was implemented]
## Test coverage
- Unit/widget tests: N passing
- Integration test matrix:
| Scenario | iOS | Android |
|----------|-----|---------|
| [scenario] | ✅ | ✅ |
## External setup completed
- [ ] [Service 1 setup]
- [ ] [Service 2 setup]
## Notes
[Any follow-up TODOs or known limitations]
```
3. **CI/CD advice for GitHub Actions (github_actions):**
Ensure workflow secrets are scoped per flavor (dev, prod). Never expose production keys in dev environment secrets. Verify the CI workflow runs `flutter test` and `flutter analyze` before deploy steps.
---
## Rules applied every phase
Always active — read before writing any code:
- `.cursor/rules/flutter-core.mdc`
- `.cursor/rules/security-standards.mdc`
- `.cursor/rules/project-context.mdc`
- Feature-type-specific rules from `FEATURE_REGISTRY.rules_to_load`
Architecture import rules for **Feature-First**:
- features/auth/ MUST NOT import from features/home/ etc.
- Shared code lives in core/ or shared/ only
- Each feature is self-contained: screen + provider + model + repo
---
## Code generation notes
**Codegen tools configured: freezed, json_serializable**
After adding any new model or injectable class, run:
```
dart run build_runner build --delete-conflicting-outputs
```
Commit generated files (`.g.dart`, `.freezed.dart`, `injection.config.dart`) — do not gitignore them.

## Phase 1: Context Loading
**When the user types `/build <request>`, do the following before writing a single line of code:**
1. Read `project-brief.yaml` from the repo root. Extract and hold in context:
- `stack.state_management` → **{{STATE_MGMT_RAW}}**
- `stack.architecture` → **{{ARCH_RAW}}**
- `stack.routing` → **{{ROUTING_RAW}}**
- `stack.backend` → **{{BACKENDS_LIST}}**
- `stack.platforms` → **{{PLATFORMS_LIST}}**
- `stack.codegen` → **{{CODEGEN_LIST}}**
- `testing.depth` → **{{TESTING_DEPTH}}**
- `testing.e2e_tool` → **{{E2E_TOOL}}**
- `features.modules` (existing features) → **{{FEATURES_LIST}}**
- `features.special` → **{{SPECIAL_FEATURES}}**
- `environments.flavors` → **{{FLAVORS_LIST}}**
- `environments.cicd` → **{{CICD_RAW}}**
2. Parse the user's free-text request. Match against `FEATURE_REGISTRY` keywords using longest-match. Multiple types are allowed if the request spans features.
3. Load `.cursor/rules/` files listed under `rules_to_load` for the matched feature type.
4. If the user's message contains a URL or GitHub repo reference, fetch and index it for pattern reference.
5. Check `features.modules` — if the feature already exists in the list, ask: "This feature is already listed in project-brief.yaml. Building additional capability on top of it? (y/n)"
6. Print the context summary table before proceeding:
```
| Field | Value |
|------------------|------------------------------|
| Feature type | [detected type] |
| State management | {{STATE_MANAGEMENT}} |
| Architecture | {{ARCHITECTURE}} |
| Backend | {{BACKEND}} |
| Platforms | {{PLATFORMS_LIST}} |
| E2E tool | {{E2E_TOOL}} |
| Rules loaded | [list from rules_to_load] |
| Existing modules | {{FEATURES_LIST}} |
```
---
## Phase 2: Deep Research
**Before touching any file, print the full research output.**
1. From the FEATURE_REGISTRY, enumerate all `pub_packages` for the detected type. For each, determine the correct version compatible with current Flutter stable (`flutter --version`). Print the full `pubspec.yaml` additions.
2. Build the complete file manifest, adapting to `{{ARCHITECTURE}}`:
**For {{ARCHITECTURE}} ({{ARCH_RAW}}):**
- `clean`: expand each feature layer explicitly → `domain/entities/`, `domain/repositories/`, `domain/usecases/`, `data/models/`, `data/datasources/`, `data/repositories/`, `presentation/`
- `feature_first`: `[feature]/[feature]_screen.dart`, `[feature]_provider.dart` or `[feature]_bloc.dart`, `[feature]_repository.dart`, `[feature]_model.dart`, `widgets/`
- `mvc`: `[feature]/model/`, `[feature]/view/`, `[feature]/controller/`
**State management file naming ({{STATE_MANAGEMENT}} / {{STATE_MGMT_RAW}}):**
- `bloc`: `[feature]_bloc.dart`, `[feature]_event.dart`, `[feature]_state.dart`
- `riverpod`: `[feature]_provider.dart`, `[feature]_notifier.dart`
- `getx`: `[feature]_controller.dart`, `[feature]_binding.dart`
3. List all modified files from `files_to_touch.modified` — show exactly what change goes in each file.
4. List all external service configuration required per platform (from `external_setup`). Only show platforms present in `{{PLATFORMS_LIST}}`.
5. Print research results in this format:
```
## Research Results
### Packages to add to pubspec.yaml
- [package_name]: ^[version]
### Files to create ({{ARCHITECTURE}} / {{STATE_MANAGEMENT}})
lib/features/[name]/... (full list)
### Files to modify
[file_path] — [what changes]
### External services requiring configuration
- [Service] ([platform]) — [what to do]
```
Do not touch any file until the user has seen this output.

## Phase 3: TDD Implementation
> **Invoke skill: `superpowers:test-driven-development`**
Follow Red → Green → Refactor strictly. Show actual terminal output at each step.
### Step 3a — Red: Write all failing tests first
1. Mirror the feature directory under `test/features/[feature]/`.
2. Write unit tests for **every scenario** in `FEATURE_REGISTRY.unit_test_scenarios` for the detected type.
3. Write widget tests for **every scenario** in `FEATURE_REGISTRY.widget_test_scenarios`.
4. Use `mocktail` for all dependencies.
5. Test naming convention: `'given [precondition], when [action], then [expected outcome]'`
6. Use the state management test pattern for **{{STATE_MANAGEMENT}}**:
```
{{TEST_PATTERN}}
```
7. Run and confirm red:
```
flutter test test/features/[feature]/ --no-pub
```
**Paste the actual output here before proceeding.**
### Step 3b — Green: Implement
1. Create domain entities and repository interfaces.
2. Create data-layer implementations wiring to `{{BACKEND}}`.
3. Create presentation layer using **{{STATE_MANAGEMENT}}** patterns.
4. Register in DI container — follow `{{ARCH_IMPORT_RULES}}`.
5. Wire the route in `{{ROUTING}}` router.
6. If `{{CODEGEN_LIST}}` is not `none`: run `dart run build_runner build --delete-conflicting-outputs` after adding models.
7. Run tests and confirm green:
```
flutter test test/features/[feature]/ --no-pub
```
**Paste the actual output here before proceeding.**
### Step 3c — Refactor
1. Review for duplication, naming, and layer boundary violations per `.cursor/rules/flutter-core.mdc`.
2. Run and confirm clean:
```
flutter analyze
```
**Paste the actual output here before proceeding.**
3. Run tests once more to confirm still green.
---
## Phase 4: Integration Test Generation
**Generate `integration_test/[feature_type]/` before asking the user to run anything.**
### Integration test file structure
Each test file follows this template:
```dart
// integration_test/[feature]/[scenario]_test.dart
// Generated by /build — {{PROJECT_NAME}}
// Feature: [feature_type] | Scenario: [scenario_name]
// Run with: flutter test integration_test/[feature]/[scenario]_test.dart -d <device_id>
import 'package:flutter_test/flutter_test.dart';
import 'package:integration_test/integration_test.dart';
import 'package:{{PACKAGE_ID}}/main.dart' as app;
void main() {
IntegrationTestWidgetsFlutterBinding.ensureInitialized();
group('[FeatureType] — [Scenario Name]', () {
setUp(() async {
// Seed state / configure mocks / reset storage
});
tearDown(() async {
// Cleanup
});
testWidgets(
'given [precondition], when [action], then [expected outcome]',
(tester) async {
app.main();
await tester.pumpAndSettle();
// test body
},
);
});
}
```
**For `{{E2E_TOOL}}` (patrol):** swap `flutter_test` imports for `package:patrol` and use Patrol's `$` NativeAutomator selector syntax.
### Files to generate
Create one file per logical scenario cluster from `FEATURE_REGISTRY.integration_test_scenarios`.
Also generate `integration_test/[feature]/README.md` with the full test matrix and run commands.
### PAUSE GATE — user must run on device
After generating all files, print this table and **stop**. Wait for the user to paste device output before Phase 6.
```
## ACTION REQUIRED — Run Integration Tests on Real Device
| File | Covers | Requires Hardware |
|------|--------|------------------|
| integration_test/[feature]/[scenario]_test.dart | [what it covers] | Yes/No |
...
Run on iOS:
flutter test integration_test/[feature]/ -d <your_ios_device_id>
Run on Android:
flutter test integration_test/[feature]/ -d <your_android_device_id>
Paste the output here to continue.
```

## Phase 5: External Setup Checklist
**Print before asking the user to verify anything. Group by service/platform. Only show sections for platforms in `{{PLATFORMS_LIST}}`.**
### Format for console/service steps (numbered list):
```markdown
### Firebase (backend: {{BACKEND}})
- [ ] 1. Open Firebase Console → [exact menu path]
- [ ] 2. [Specific action]
- [ ] 3. Download updated config file → place at [exact path]
```
### Format for native platform steps (table):
```markdown
### iOS Setup
| Step | Where | What | How to Verify |
|------|-------|------|---------------|
| [Step name] | [Xcode location / file path] | [Exact change] | [Verification method] |
```
```markdown
### Android Setup
- [ ] 1. Open `android/app/src/main/AndroidManifest.xml`
- Add: `<uses-permission android:name="[permission]"/>`
- [ ] 2. [Next step with exact value]
```
### Flavor scoping note (flavors: {{FLAVORS_LIST}})
Config files and API keys must be scoped per flavor. Never place production keys in `dev` flavor files. Follow the pattern established in `.cursor/rules/` for flavor-based configuration.
---
## Phase 6: Verification Gate
> **Invoke skill: `superpowers:verification-before-completion`**
**Do not claim completion without pasting real output for every item below.**
```
VERIFICATION REQUIRED — paste real output for each:
[ ] flutter test test/features/[feature]/ --no-pub
Required: "All N tests passed."
[ ] flutter analyze
Required: "No issues found!"
[ ] Integration test device output (from Phase 4 pause gate)
Required: actual device test output
[ ] lefthook run pre-commit
Required: all hooks passed
```
If any check fails: invoke `superpowers:systematic-debugging` to diagnose before retrying.
Do not proceed to Phase 7 until all four checks are green.
---
## Phase 7: PR Preparation
> **Invoke skill: `superpowers:finishing-a-development-branch`**
1. **Commit message** (conventional commits format):
```
feat([feature_type]): implement [feature] end-to-end
```
2. **PR description template:**
```markdown
## What
[One sentence: what feature was implemented]
## Test coverage
- Unit/widget tests: N passing
- Integration test matrix:
| Scenario | iOS | Android |
|----------|-----|---------|
| [scenario] | ✅ | ✅ |
## External setup completed
- [ ] [Service 1 setup]
- [ ] [Service 2 setup]
## Notes
[Any follow-up TODOs or known limitations]
```
3. **CI/CD advice for {{CICD_TOOL}} ({{CICD_RAW}}):**
Ensure workflow secrets are scoped per flavor ({{FLAVORS_LIST}}). Never expose production keys in dev environment secrets. Verify the CI workflow runs `flutter test` and `flutter analyze` before deploy steps.
---
## Rules applied every phase
Always active — read before writing any code:
- `.cursor/rules/flutter-core.mdc`
- `.cursor/rules/security-standards.mdc`
- `.cursor/rules/project-context.mdc`
- Feature-type-specific rules from `FEATURE_REGISTRY.rules_to_load`
Architecture import rules for **{{ARCHITECTURE}}**:
{{ARCH_IMPORT_RULES}}

## Code generation notes
**Codegen tools configured: {{CODEGEN_LIST}}**
After adding any new model or injectable class, run:
```
dart run build_runner build --delete-conflicting-outputs
```
Commit generated files (`.g.dart`, `.freezed.dart`, `injection.config.dart`) — do not gitignore them.
