# Project Planning Skill

Transform specification into implementation plan with architecture design and dependency-ordered tasks.

## Delegation

For detailed task planning workflows, this skill delegates to `spec-kit:task-planning` as the canonical implementation. Use this skill for quick planning needs; use spec-kit for comprehensive project plans.

## When To Use

- After specification phase completes
- Need to design system architecture
- Need task breakdown for implementation
- Planning sprints and resource allocation
- Converting requirements into actionable tasks
- Defining component interfaces and dependencies

## When NOT To Use

- No specification exists yet (use `Skill(attune:project-specification)` first)
- Still exploring problem space (use `Skill(attune:project-brainstorming)` instead)
- Ready to execute existing plan (use `Skill(attune:project-execution)` instead)
- Need to adjust running project (update plan incrementally, don't restart)

## Integration

**With superpowers**:
- Uses `Skill(superpowers:writing-plans)` for structured planning
- Applies checkpoint-based execution patterns
- Uses dependency analysis framework

**Without superpowers**:
- Standalone planning methodology
- Task breakdown templates
- Dependency tracking patterns

## Planning Phases

### Phase 1: Architecture Design

**Activities**:
1. Identify system components
2. Define component responsibilities
3. Design interfaces between components
4. Map data flows
5. Select technologies

**Output**: Architecture documentation with diagrams

### Phase 2: Task Breakdown

**Activities**:
1. Decompose FRs into implementation tasks
2. Add testing tasks for each FR
3. Add infrastructure tasks
4. Add documentation tasks
5. Estimate each task

**Output**: Task list with estimates

### Phase 3: Dependency Analysis

**Activities**:
1. Identify task dependencies
2. Create dependency graph
3. Identify critical path
4. Detect circular dependencies
5. Optimize for parallelization

**Output**: Dependency-ordered task execution plan

### Phase 4: Sprint Planning

**Activities**:
1. Group tasks into sprints
2. Balance sprint workload
3. Identify milestones
4. Plan releases
5. Allocate resources

**Output**: Sprint schedule with milestones

## Architecture Design Patterns

### Component Identification

**Questions**:
- What are the major functional areas?
- What concerns should be separated?
- What components can be developed independently?
- What components can be reused?

**Common Patterns**:
- **Frontend/Backend**: Separate UI from business logic
- **API Layer**: Separate interface from implementation
- **Data Layer**: Separate data access from business logic
- **Integration Layer**: Isolate external dependencies

### Component Template

```markdown
### Component: [Name]

**Responsibility**: [What this component does]

**Technology**: [Stack and tools]

**Interfaces**:
- [Interface 1]: [Description]
- [Interface 2]: [Description]

**Dependencies**:
- [Component 1]: [What's needed]
- [Component 2]: [What's needed]

**Data**:
- [Data structure 1]
- [Data structure 2]

**Configuration**:
- [Config param 1]
- [Config param 2]
```

## Task Breakdown Template

```markdown
### TASK-[XXX]: [Task Name]

**Description**: [What needs to be done]

**Type**: Implementation | Testing | Documentation | Infrastructure | Deployment
**Priority**: P0 (Critical) | P1 (High) | P2 (Medium) | P3 (Low)
**Estimate**: [Story points or hours]
**Dependencies**: TASK-XXX, TASK-YYY
**Sprint**: Sprint N
**Assignee**: [Name or TBD]

**Linked Requirements**: FR-XXX, NFR-YYY

**Acceptance Criteria**:
- [ ] [Criterion 1]
- [ ] [Criterion 2]
- [ ] Tests passing
- [ ] Documentation updated

**Technical Notes**:
- [Implementation detail 1]
- [Implementation detail 2]

**Testing Requirements**:
- Unit tests: [What to test]
- Integration tests: [What to test]
- E2E tests: [What to test]

**Definition of Done**:
- [ ] Code complete
- [ ] Tests passing
- [ ] Code reviewed
- [ ] Documentation updated
- [ ] Deployed to staging
```

## Task Estimation Guidelines

**Story Points (Fibonacci)**:
- **1 point**: < 2 hours, trivial, well-understood
- **2 points**: 2-4 hours, straightforward
- **3 points**: 4-8 hours, some complexity
- **5 points**: 1-2 days, moderate complexity
- **8 points**: 2-3 days, significant complexity
- **13 points**: 3-5 days, high complexity (consider breaking down)
- **21 points**: > 5 days, very complex (MUST break down)

**Factors to consider**:
- Technical complexity
- Uncertainty/unknowns
- Dependencies on other work
- Testing requirements
- Documentation needs

## Dependency Graph

**Notation**:
```
TASK-001 (Foundation)
    ├─▶ TASK-002 (Database schema)
    │       ├─▶ TASK-003 (Models)
    │       └─▶ TASK-011 (Data import)
    └─▶ TASK-004 (Authentication)
            └─▶ TASK-005 (Auth middleware)
                    └─▶ TASK-010 (Protected endpoints)
```

**Validation**:
- No circular dependencies (A depends on B, B depends on A)
- Critical path identified
- Parallel work opportunities identified
- Blocking tasks highlighted

## Sprint Structure

**Sprint Template**:
```markdown
## Sprint [N]: [Focus Area]

**Dates**: [Start] - [End]
**Goal**: [Sprint objective]
**Capacity**: [Team capacity in story points]

### Planned Tasks ([X] story points)
- TASK-XXX ([N] points)
- TASK-YYY ([M] points)
- ...

### Deliverable
[What will be demonstrable at sprint end]

### Risks
- [Risk 1 with mitigation]
- [Risk 2 with mitigation]

### Dependencies
- [External dependency 1]
- [External dependency 2]
```

## Risk Assessment

**Risk Template**:
```markdown
| Risk | Impact | Probability | Mitigation |
|------|--------|-------------|------------|
| [Risk description] | High/Med/Low | High/Med/Low | [How to address] |
```

**Common Risks**:
- Technology unknowns
- Third-party API dependencies
- Resource availability
- Scope creep
- Performance issues
- Security vulnerabilities

## Next Steps

1. Review plan with team
2. Initialize project with `/attune:project-init`
3. Start execution with `/attune:execute`
```

## Quality Checks

Before completing plan:

- ✅ All architecture components documented
- ✅ All FRs mapped to tasks
- ✅ All tasks have acceptance criteria
- ✅ Dependencies are acyclic
- ✅ Effort estimates provided
- ✅ Critical path identified
- ✅ Risks assessed with mitigations
- ✅ Sprints balanced by capacity

## Post-Completion: Workflow Continuation (REQUIRED)

**Automatic Trigger**: After Quality Checks pass and `docs/implementation-plan.md` is saved, MUST auto-invoke the next phase.

**When continuation is invoked**:
1. Verify `docs/implementation-plan.md` exists and is non-empty
2. Display checkpoint message to user:
   ```
   Implementation plan complete. Saved to docs/implementation-plan.md.
   Proceeding to execution phase...
   ```
3. Invoke next phase:
   ```
   Skill(attune:project-execution)
   ```

**Bypass Conditions** (ONLY skip continuation if ANY true):
- `--standalone` flag was provided by the user
- `docs/implementation-plan.md` does not exist or is empty (phase failed)
- User explicitly requests to stop after planning

**Do NOT prompt the user for confirmation** — this is a lightweight checkpoint, not an interactive gate. The user can always interrupt if needed.

## Troubleshooting

### Common Issues

If you find circular dependencies in your task graph, break one of the tasks into smaller sub-tasks. If sprint capacity is consistently exceeded, re-estimate tasks using the Fibonacci scale or reduce sprint scope.
