description: Generate implementation tasks for a specification argument-hint: [-y] [--sequential] arguments: feature-name: $1 -y flag: $2 --sequential flag: $3 # Implementation Tasks Generator - **Mission**: Generate detailed, actionable implementation tasks that translate technical design into executable work items - **Success Criteria**: - All requirements mapped to specific tasks - Tasks properly sized (1-3 hours each) - Clear task progression with proper hierarchy - Natural language descriptions focused on capabilities ## Core Task Generate implementation tasks for feature **$1** based on approved requirements and design. ## Execution Steps ### Step 1: Load Context **Read all necessary context**: - `{{KIRO_DIR}}/specs/$1/spec.json`, `requirements.md`, `design.md` - `{{KIRO_DIR}}/specs/$1/tasks.md` (if exists, for merge mode) - **Entire `{{KIRO_DIR}}/steering/` directory** for complete project memory **Validate approvals**: - If `-y` flag provided ($2 == "-y"): Auto-approve requirements and design in spec.json - Otherwise: Verify both approved (stop if not, see Safety & Fallback) - Determine sequential mode based on presence of `--sequential` ### Step 2: Generate Implementation Tasks **Load generation rules and template**: - Read `{{KIRO_DIR}}/settings/rules/tasks-generation.md` for principles - If `sequential` is false: Read `{{KIRO_DIR}}/settings/rules/tasks-parallel-analysis.md` for parallel judgement criteria - Read `{{KIRO_DIR}}/settings/templates/specs/tasks.md` for format (supports `(P)` markers) **Generate task list following all rules**: - Use language specified in spec.json - Map all requirements to tasks - When documenting requirement coverage, list IDs only (comma-separated) without descriptive suffixes or parentheses - Ensure all design components included - Verify task progression is logical and incremental - Collapse single-subtask structures by promoting them to major tasks and avoid duplicating details on container-only major tasks (use template patterns accordingly) - Apply `(P)` markers to tasks that satisfy parallel criteria (omit markers when sequential mode requested) - Mark optional test coverage subtasks with `- [ ]*` only when they strictly cover acceptance criteria already satisfied by core implementation and can be deferred post-MVP - If existing tasks.md found, merge with new content ### Step 3: Finalize **Write and update**: - Create/update `{{KIRO_DIR}}/specs/$1/tasks.md` - Update spec.json metadata: - Set `phase: "tasks-generated"` - Set `approvals.tasks.generated: true, approved: false` - Set `approvals.requirements.approved: true` - Set `approvals.design.approved: true` - Update `updated_at` timestamp ## Critical Constraints - **Follow rules strictly**: All principles in tasks-generation.md are mandatory - **Natural Language**: Describe what to do, not code structure details - **Complete Coverage**: ALL requirements must map to tasks - **Maximum 2 Levels**: Major tasks and sub-tasks only (no deeper nesting) - **Sequential Numbering**: Major tasks increment (1, 2, 3...), never repeat - **Task Integration**: Every task must connect to the system (no orphaned work) ## Tool Guidance - **Read first**: Load all context, rules, and templates before generation - **Write last**: Generate tasks.md only after complete analysis and verification ## Output Description Provide brief summary in the language specified in spec.json: 1. **Status**: Confirm tasks generated at `{{KIRO_DIR}}/specs/$1/tasks.md` 2. **Task Summary**: - Total: X major tasks, Y sub-tasks - All Z requirements covered - Average task size: 1-3 hours per sub-task 3. **Quality Validation**: - ✅ All requirements mapped to tasks - ✅ Task dependencies verified - ✅ Testing tasks included 4. **Next Action**: Review tasks and proceed when ready **Format**: Concise (under 200 words) ## Safety & Fallback ### Error Scenarios **Requirements or Design Not Approved**: - **Stop Execution**: Cannot proceed without approved requirements and design - **User Message**: "Requirements and design must be approved before task generation" - **Suggested Action**: "Run `/prompts:kiro-spec-tasks $1 -y` to auto-approve both and proceed" **Missing Requirements or Design**: - **Stop Execution**: Both documents must exist - **User Message**: "Missing requirements.md or design.md at `{{KIRO_DIR}}/specs/$1/`" - **Suggested Action**: "Complete requirements and design phases first" **Incomplete Requirements Coverage**: - **Warning**: "Not all requirements mapped to tasks. Review coverage." - **User Action Required**: Confirm intentional gaps or regenerate tasks **Template/Rules Missing**: - **User Message**: "Template or rules files missing in `{{KIRO_DIR}}/settings/`" - **Fallback**: Use inline basic structure with warning - **Suggested Action**: "Check repository setup or restore template files" ### Next Phase: Implementation **Before Starting Implementation**: - **IMPORTANT**: Clear conversation history and free up context before running `/prompts:kiro-spec-impl` - This applies when starting first task OR switching between tasks - Fresh context ensures clean state and proper task focus **If Tasks Approved**: - Execute specific task: `/prompts:kiro-spec-impl $1 1.1` (recommended: clear context between each task) - Execute multiple tasks: `/prompts:kiro-spec-impl $1 1.1,1.2` (use cautiously, clear context between tasks) - Without arguments: `/prompts:kiro-spec-impl $1` (executes all pending tasks - NOT recommended due to context bloat) **If Modifications Needed**: - Provide feedback and re-run `/prompts:kiro-spec-tasks $1` - Existing tasks used as reference (merge mode) **Note**: The implementation phase will guide you through executing tasks with appropriate context and validation.
