## User Input
|
|
|
|
```text
|
|
$ARGUMENTS
|
|
```
|
|
|
|
You **MUST** consider the user input before proceeding (if not empty).
|
|
|
|
## Pre-Execution Checks
|
|
|
|
**Check for extension hooks (before tasks generation)**:
|
|
- Check if `.specify/extensions.yml` exists in the project root.
|
|
- If it exists, read it and look for entries under the `hooks.before_tasks` key
|
|
- If the YAML cannot be parsed or is invalid, skip hook checking silently and continue normally
|
|
- Filter out hooks where `enabled` is explicitly `false`. Treat hooks without an `enabled` field as enabled by default.
|
|
- For each remaining hook, do **not** attempt to interpret or evaluate hook `condition` expressions:
|
|
- If the hook has no `condition` field, or it is null/empty, treat the hook as executable
|
|
- If the hook defines a non-empty `condition`, skip the hook and leave condition evaluation to the HookExecutor implementation
|
|
- When constructing slash commands from hook command names, replace dots (`.`) with hyphens (`-`). For example, `speckit.git.commit` → `/speckit-git-commit`.
|
|
- For each executable hook, output the following based on its `optional` flag:
|
|
- **Optional hook** (`optional: true`):
|
|
```
|
|
## Extension Hooks
|
|
|
|
**Optional Pre-Hook**: {extension}
|
|
Command: `/{command}`
|
|
Description: {description}
|
|
|
|
Prompt: {prompt}
|
|
To execute: `/{command}`
|
|
```
|
|
- **Mandatory hook** (`optional: false`):
|
|
```
|
|
## Extension Hooks
|
|
|
|
**Automatic Pre-Hook**: {extension}
|
|
Executing: `/{command}`
|
|
EXECUTE_COMMAND: {command}
|
|
|
|
Wait for the result of the hook command before proceeding to the Outline.
|
|
```
|
|
- If no hooks are registered or `.specify/extensions.yml` does not exist, skip silently
|
|
|
|
## Outline
|
|
|
|
1. **Setup**: Run `.specify/scripts/bash/setup-tasks.sh --json` from repo root and parse FEATURE_DIR, TASKS_TEMPLATE, and AVAILABLE_DOCS list. `FEATURE_DIR` and `TASKS_TEMPLATE` must be absolute paths when provided. `AVAILABLE_DOCS` is a list of document names/relative paths available under `FEATURE_DIR` (for example `research.md` or `contracts/`). For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot").
|
|
|
|
2. **Load design documents**: Read from FEATURE_DIR:
|
|
- **Required**: plan.md (tech stack, libraries, structure), spec.md (user stories with priorities)
|
|
- **Optional**: data-model.md (entities), contracts/ (interface contracts), research.md (decisions), quickstart.md (test scenarios)
|
|
- **IF EXISTS**: Load `.specify/memory/constitution.md` for project principles and governance constraints
|
|
- Note: Not all projects have all documents. Generate tasks based on what's available.
|
|
|
|
3. **Execute task generation workflow**:
|
|
- Load plan.md and extract tech stack, libraries, project structure
|
|
- Load spec.md and extract user stories with their priorities (P1, P2, P3, etc.)
|
|
- If data-model.md exists: Extract entities and map to user stories
|
|
- If contracts/ exists: Map interface contracts to user stories
|
|
- If research.md exists: Extract decisions for setup tasks
|
|
- Generate tasks organized by user story (see Task Generation Rules below)
|
|
- Generate dependency graph showing user story completion order
|
|
- Create parallel execution examples per user story
|
|
- Validate task completeness (each user story has all needed tasks, independently testable)
|
|
|
|
4. **Generate tasks.md**: Read the tasks template from TASKS_TEMPLATE (from the JSON output above) and use it as structure. If TASKS_TEMPLATE is empty, fall back to `.specify/templates/tasks-template.md`. Fill with:
|
|
- Correct feature name from plan.md
|
|
- Phase 1: Setup tasks (project initialization)
|
|
- Phase 2: Foundational tasks (blocking prerequisites for all user stories)
|
|
- Phase 3+: One phase per user story (in priority order from spec.md)
|
|
- Each phase includes: story goal, independent test criteria, tests (if requested), implementation tasks
|
|
- Final Phase: Polish & cross-cutting concerns
|
|
- All tasks must follow the strict checklist format (see Task Generation Rules below)
|
|
- Clear file paths for each task
|
|
- Dependencies section showing story completion order
|
|
- Parallel execution examples per story
|
|
- Implementation strategy section (MVP first, incremental delivery)
|
|
|
|
## Mandatory Post-Execution Hooks
|
|
|
|
**You MUST complete this section before reporting completion to the user.**
|
|
|
|
Check if `.specify/extensions.yml` exists in the project root.
|
|
- If it does not exist, or no hooks are registered under `hooks.after_tasks`, skip to the Completion Report.
|
|
- If it exists, read it and look for entries under the `hooks.after_tasks` key.
|
|
- If the YAML cannot be parsed or is invalid, skip hook checking silently and continue to the Completion Report.
|
|
- Filter out hooks where `enabled` is explicitly `false`. Treat hooks without an `enabled` field as enabled by default.
|
|
- For each remaining hook, do **not** attempt to interpret or evaluate hook `condition` expressions:
|
|
- If the hook has no `condition` field, or it is null/empty, treat the hook as executable
|
|
- If the hook defines a non-empty `condition`, skip the hook and leave condition evaluation to the HookExecutor implementation
|
|
- When constructing slash commands from hook command names, replace dots (`.`) with hyphens (`-`). For example, `speckit.git.commit` → `/speckit-git-commit`.
|
|
- For each executable hook, output the following based on its `optional` flag:
|
|
- **Mandatory hook** (`optional: false`) — **You MUST emit `EXECUTE_COMMAND:` for each mandatory hook**:
|
|
```
|
|
## Extension Hooks
|
|
|
|
**Automatic Hook**: {extension}
|
|
Executing: `/{command}`
|
|
EXECUTE_COMMAND: {command}
|
|
```
|
|
- **Optional hook** (`optional: true`):
|
|
```
|
|
## Extension Hooks
|
|
|
|
**Optional Hook**: {extension}
|
|
Command: `/{command}`
|
|
Description: {description}
|
|
|
|
Prompt: {prompt}
|
|
To execute: `/{command}`
|
|
```
|
|
|
|
## Completion Report
|
|
|
|
Output path to generated tasks.md and summary:
|
|
- Total task count
|
|
- Task count per user story
|
|
- Parallel opportunities identified
|
|
- Independent test criteria for each story
|
|
- Suggested MVP scope (typically just User Story 1)
|
|
- Format validation: Confirm ALL tasks follow the checklist format (checkbox, ID, labels, file paths)
|
|
|
|
Context for task generation: $ARGUMENTS
|
|
|
|
The tasks.md should be immediately executable - each task must be specific enough that an LLM can complete it without additional context.
|
|
|
|
## Task Generation Rules
|
|
|
|
**CRITICAL**: Tasks MUST be organized by user story to enable independent implementation and testing.
|
|
|
|
**Tests are OPTIONAL**: Only generate test tasks if explicitly requested in the feature specification or if user requests TDD approach.
|
|
|
|
### Checklist Format (REQUIRED)
|
|
|
|
Every task MUST strictly follow this format:
|
|
|
|
```text
|
|
- [ ] [TaskID] [P?] [Story?] Description with file path
|
|
```
|
|
|
|
**Format Components**:
|
|
|
|
1. **Checkbox**: ALWAYS start with `- [ ]` (markdown checkbox)
|
|
2. **Task ID**: Sequential number (T001, T002, T003...) in execution order
|
|
3. **[P] marker**: Include ONLY if task is parallelizable (different files, no dependencies on incomplete tasks)
|
|
4. **[Story] label**: REQUIRED for user story phase tasks only
|
|
- Format: [US1], [US2], [US3], etc. (maps to user stories from spec.md)
|
|
- Setup phase: NO story label
|
|
- Foundational phase: NO story label
|
|
- User Story phases: MUST have story label
|
|
- Polish phase: NO story label
|
|
5. **Description**: Clear action with exact file path
|
|
|
|
**Examples**:
|
|
|
|
- ✅ CORRECT: `- [ ] T001 Create project structure per implementation plan`
|
|
- ✅ CORRECT: `- [ ] T005 [P] Implement authentication middleware in src/middleware/auth.py`
|
|
- ✅ CORRECT: `- [ ] T012 [P] [US1] Create User model in src/models/user.py`
|
|
- ✅ CORRECT: `- [ ] T014 [US1] Implement UserService in src/services/user_service.py`
|
|
- ❌ WRONG: `- [ ] Create User model` (missing ID and Story label)
|
|
- ❌ WRONG: `T001 [US1] Create model` (missing checkbox)
|
|
- ❌ WRONG: `- [ ] [US1] Create User model` (missing Task ID)
|
|
- ❌ WRONG: `- [ ] T001 [US1] Create model` (missing file path)
|
|
|
|
### Task Organization
|
|
|
|
1. **From User Stories (spec.md)** - PRIMARY ORGANIZATION:
|
|
- Each user story (P1, P2, P3...) gets its own phase
|
|
- Map all related components to their story:
|
|
- Models needed for that story
|
|
- Services needed for that story
|
|
- Interfaces/UI needed for that story
|
|
- If tests requested: Tests specific to that story
|
|
- Mark story dependencies (most stories should be independent)
|
|
|
|
2. **From Contracts**:
|
|
- Map each interface contract → to the user story it serves
|
|
- If tests requested: Each interface contract → contract test task [P] before implementation in that story's phase
|
|
|
|
3. **From Data Model**:
|
|
- Map each entity to the user story(ies) that need it
|
|
- If entity serves multiple stories: Put in earliest story or Setup phase
|
|
- Relationships → service layer tasks in appropriate story phase
|
|
|
|
4. **From Setup/Infrastructure**:
|
|
- Shared infrastructure → Setup phase (Phase 1)
|
|
- Foundational/blocking tasks → Foundational phase (Phase 2)
|
|
- Story-specific setup → within that story's phase
|
|
|
|
### Phase Structure
|
|
|
|
- **Phase 1**: Setup (project initialization)
|
|
- **Phase 2**: Foundational (blocking prerequisites - MUST complete before user stories)
|
|
- **Phase 3+**: User Stories in priority order (P1, P2, P3...)
|
|
- Within each story: Tests (if requested) → Models → Services → Endpoints → Integration
|
|
- Each phase should be a complete, independently testable increment
|
|
- **Final Phase**: Polish & Cross-Cutting Concerns
|
|
|
|
