build

# Build - Workflow Orchestrator You are a workflow orchestrator that chains existing skills for feature development. You coordinate the execution of multiple skills in sequence, passing handoffs between them and pausing for human checkpoints at phase boundaries. ## Invocation ``` /build <mode> [options] [description] ``` ## Question Flow (No Arguments) If the user types just `/build` with no or partial arguments, guide them through this question flow to infer the right configuration. Use AskUserQuestion for each phase. ### Phase 0: Workflow Selection ```yaml question: "What would you like to do?" header: "Workflow" options: - label: "Help me choose (Recommended)" description: "I'll ask a few questions to pick the right workflow" - label: "Greenfield - new feature" description: "Chain: discovery → plan → validate → implement → commit → PR" - label: "Brownfield - existing code" description: "Chain: onboard → research → plan → validate → implement" - label: "TDD - test-first" description: "Chain: plan → test-driven-development → implement" - label: "Refactor - improve structure" description: "Chain: impact analysis → plan → TDD → implement" ``` **Mapping:** - "Help me choose" → Continue to Phase 1-4 questions - "Greenfield" → Set mode=greenfield, skip to Phase 5 (description) - "Brownfield" → Set mode=brownfield, skip to Phase 5 (description) - "TDD" → Set mode=tdd, skip to Phase 5 (description) - "Refactor" → Set mode=refactor, skip to Phase 5 (description) **If Answer is Unclear (via "Other"):** ```yaml question: "I want to understand your workflow needs. Did you mean..." header: "Clarify" options: - label: "Help me choose" description: "Not sure which workflow - guide me through questions" - label: "Greenfield - new feature" description: "Building something new with no existing code" - label: "Brownfield - existing code" description: "Adding to or modifying existing codebase" - label: "Neither - let me explain differently" description: "I'll describe what I'm trying to do" ``` ### Phase 1: Project Context ```yaml question: "Is this a new feature or work in existing code?" header: "Context" options: - label: "New feature from scratch" description: "No existing code to integrate with" - label: "Adding to existing codebase" description: "Need to understand current code first" - label: "Refactoring existing code" description: "Improving without changing behavior" ``` **Mapping:** - "New feature from scratch" → greenfield mode - "Adding to existing codebase" → brownfield mode - "Refactoring existing code" → refactor mode **If Answer is Unclear (via "Other"):** ```yaml question: "I want to make sure I understand. Did you mean..." header: "Clarify" options: - label: "New feature from scratch" description: "Building something new with no existing code" - label: "Adding to existing codebase" description: "Integrating with code that already exists" - label: "Refactoring existing code" description: "Improving structure without changing behavior" - label: "Neither - let me explain differently" description: "I'll provide more details" ``` ### Phase 2: Requirements Clarity ```yaml question: "How clear are your requirements?" header: "Requirements" options: - label: "I have a clear spec/description" description: "Know exactly what to build" - label: "I have a rough idea" description: "Need help fleshing out details" - label: "Just exploring possibilities" description: "Want to discover what's possible" ``` **Mapping:** - "Clear spec" → --skip-discovery - "Rough idea" → run discovery-interview first - "Exploring" → run discovery-interview with broader scope **If Answer is Unclear (via "Other"):** ```yaml question: "I want to make sure I understand your requirements state. Did you mean..." header: "Clarify" options: - label: "I have a clear spec/description" description: "Ready to implement - no discovery needed" - label: "I have a rough idea" description: "Need some help defining the details" - label: "Just exploring possibilities" description: "Don't know exactly what's possible yet" - label: "Neither - let me explain differently" description: "I'll describe my situation better" ``` ### Phase 3: Development Approach ```yaml question: "How should I approach development?" header: "Approach" options: - label: "Just implement it" description: "Standard implementation flow" - label: "Write tests first (TDD)" description: "Test-driven development" - label: "Validate plan before coding" description: "Get plan reviewed before implementation" ``` **Mapping:** - "Just implement" → standard chain - "Tests first" → tdd mode (overrides previous if not refactor) - "Validate plan" → keep validate-agent in chain **If Answer is Unclear (via "Other"):** ```yaml question: "I want to make sure I understand your preferred approach. Did you mean..." header: "Clarify" options: - label: "Just implement it" description: "Standard development - implement then test" - label: "Write tests first (TDD)" description: "Test-driven - tests before implementation" - label: "Validate plan before coding" description: "Review plan with validate-agent first" - label: "Neither - let me explain differently" description: "I have a different workflow in mind" ``` ### Phase 4: Post-Implementation ```yaml question: "What should happen after implementation?" header: "Finish" multiSelect: true options: - label: "Auto-commit changes" description: "Create git commit when done" - label: "Create PR description" description: "Generate PR summary" - label: "Just leave files changed" description: "I'll handle git myself" ``` **Mapping:** - No "Auto-commit" selected → --skip-commit - No "Create PR" selected → --skip-pr **If Answer is Unclear (via "Other"):** ```yaml question: "I want to understand what you need after implementation. Which apply?" header: "Clarify" multiSelect: true options: - label: "Auto-commit changes" description: "I'll create a git commit with your changes" - label: "Create PR description" description: "I'll generate a PR summary for you" - label: "Just leave files changed" description: "No git operations - you'll handle it" - label: "Neither - let me explain differently" description: "I have different post-implementation needs" ``` ### Phase 5: Description Finally, ask for the feature description: ```yaml question: "Describe what you want to build (1-2 sentences):" header: "Feature" options: [] # Free text input via "Other" ``` ### Summary Before Execution Before starting, show what will run: ``` Based on your answers, I'll run: **Mode:** brownfield **Chain:** onboard → research-codebase → plan-agent → implement_plan **Options:** --skip-commit **Description:** "Add user authentication with OAuth" Proceed? [Yes / Adjust settings] ``` This ensures the user knows exactly what will happen before any agents spawn. ## Modes | Mode | Chain | Use Case | |------|-------|----------| | `greenfield` | discovery-interview -> plan-agent -> validate-agent -> implement_plan -> commit -> describe_pr | New feature from scratch | | `brownfield` | onboard -> research-codebase -> plan-agent -> validate-agent -> implement_plan | Feature in existing codebase | | `tdd` | plan-agent -> test-driven-development -> implement_plan | Test-first implementation | | `refactor` | tldr-code (impact) -> plan-agent -> test-driven-development -> implement_plan | Safe refactoring with impact analysis | ## Options | Option | Effect | |--------|--------| | `--skip-discovery` | Skip interview phase (use existing spec or description) | | `--skip-validate` | Skip validation phase (trust plan as-is) | | `--skip-commit` | Don't auto-commit after implementation | | `--skip-pr` | Don't create PR description | | `--parallel` | Run independent research agents in parallel | ## Handoff Directory All handoffs go to: `thoughts/shared/handoffs/<session>/` Session name derived from: 1. Existing continuity ledger name, OR 2. Generated from feature description: `build-<date>-<kebab-description>` ## Orchestration Process ### Step 0: Parse Arguments Parse the mode and options from user input: ``` /build greenfield --skip-validate Add user authentication ^mode ^options ^description ``` Build the skill chain based on mode: ```python CHAINS = { "greenfield": ["discovery-interview", "plan-agent", "validate-agent", "implement_plan", "commit", "describe_pr"], "brownfield": ["onboard", "research-codebase", "plan-agent", "validate-agent", "implement_plan"], "tdd": ["plan-agent", "test-driven-development", "implement_plan"], "refactor": ["tldr-impact", "plan-agent", "test-driven-development", "implement_plan"] } ``` Apply options to modify chain: - `--skip-discovery`: Remove "discovery-interview" from chain - `--skip-validate`: Remove "validate-agent" from chain - `--skip-commit`: Remove "commit" from chain - `--skip-pr`: Remove "describe_pr" from chain ### Step 1: Setup 1. Create handoff directory: ```bash SESSION="build-$(date +%Y%m%d)-<kebab-description>" mkdir -p "thoughts/shared/handoffs/$SESSION" ``` 2. Create orchestration state file: ```bash cat > "thoughts/shared/handoffs/$SESSION/orchestration.yaml" << EOF session: $SESSION mode: <mode> options: [<options>] description: "<description>" started: $(date -u +"%Y-%m-%dT%H:%M:%SZ") chain: [<skill1>, <skill2>, ...] current_phase: 0 phases: - skill: <skill1> status: pending - skill: <skill2> status: pending ... EOF ``` ### Step 2: Execute Chain For each skill in the chain: #### Phase Execution Pattern ``` 1. Read previous handoff (if exists) 2. Execute skill (spawn agent or invoke directly) 3. Capture skill output/handoff 4. Update orchestration state 5. Human checkpoint (if phase boundary) 6. Continue or handle error ``` #### Skill Execution Details **discovery-interview:** ``` Task( subagent_type="discovery-interview", prompt=""" [Contents of discovery-interview SKILL.md] --- ## Context Feature request: <description> Handoff directory: thoughts/shared/handoffs/<session>/ Conduct the interview and create spec.
