do - Feature Development Orchestrator

An orchestrator for systematic feature development. Invoke agents via codeagent-wrapper, never write code directly.

Loop Initialization (REQUIRED)

When triggered via /do <task>, follow these steps:

Step 1: Ask about worktree mode

Use AskUserQuestion to ask:

Develop in a separate worktree? (Isolates changes from main branch)
- Yes (Recommended for larger changes)
- No (Work directly in current directory)

Step 2: Initialize state

# If worktree mode selected:
python3 "${SKILL_DIR}/scripts/setup-do.py" --worktree "<task description>"

# If no worktree:
python3 "${SKILL_DIR}/scripts/setup-do.py" "<task description>"

This creates .claude/do.{task_id}.local.md with:

• active: true
• current_phase: 1
• max_phases: 5
• completion_promise: "<promise>DO_COMPLETE</promise>"
• use_worktree: true/false

Worktree Mode

When use_worktree: true in state file, ALL codeagent-wrapper calls that modify code MUST include --worktree:

# With worktree mode enabled
codeagent-wrapper --worktree --agent develop - . <<'EOF'
...
EOF

# Parallel tasks with worktree
codeagent-wrapper --worktree --parallel <<'EOF'
---TASK---
id: task1
agent: develop
workdir: .
---CONTENT---
...
EOF

The --worktree flag tells codeagent-wrapper to create/use a worktree internally. Read-only agents (code-explorer, code-architect, code-reviewer) do NOT need --worktree.

Loop State Management

After each phase, update .claude/do.{task_id}.local.md frontmatter:

current_phase: <next phase number>
phase_name: "<next phase name>"

When all 5 phases complete, output the completion signal:

<promise>DO_COMPLETE</promise>

To abort early, set active: false in the state file.

Hard Constraints

1. Never write code directly. Delegate all code changes to codeagent-wrapper agents.
2. Pass complete context forward. Every agent invocation includes the Context Pack.
3. Parallel-first. Run independent tasks via codeagent-wrapper --parallel.
4. Update state after each phase. Keep .claude/do.{task_id}.local.md current.
5. Expect long-running codeagent-wrapper calls. High-reasoning modes can take a long time; stay in the orchestrator role and wait for agents to complete.
6. Timeouts are not an escape hatch. If a codeagent-wrapper invocation times out/errors, retry (split/narrow the task if needed); never switch to direct implementation.
7. Respect worktree setting. If use_worktree: true, always pass --worktree to develop agent calls.

Agents

Agent	Purpose	Needs --worktree
code-explorer	Trace code, map architecture, find patterns	No (read-only)
code-architect	Design approaches, file plans, build sequences	No (read-only)
code-reviewer	Review for bugs, simplicity, conventions	No (read-only)
develop	Implement code, run tests	Yes (if worktree enabled)

Issue Severity Definitions

Blocking issues (require user input):

• Impacts core functionality or correctness
• Security vulnerabilities
• Architectural conflicts with existing patterns
• Ambiguous requirements with multiple valid interpretations

Minor issues (auto-fix without asking):

• Code style inconsistencies
• Naming improvements
• Missing documentation
• Non-critical test coverage gaps

<specific task>

## Acceptance Criteria
<checkable outputs>

5-Phase Workflow

Phase 1: Understand (Parallel, No Interaction)

Goal: Understand requirements and map codebase simultaneously.

Actions: Run code-architect and 2-3 code-explorer tasks in parallel.

codeagent-wrapper --parallel <<'EOF'
---TASK---
id: p1_requirements
agent: code-architect
workdir: .
---CONTENT---
## Original User Request
/do <request>

## Context Pack
- Code-explorer output: None
- Code-architect output: None

## Current Task
1. Analyze requirements completeness (score 1-10)
2. Extract explicit requirements, constraints, acceptance criteria
3. Identify blocking questions (issues that prevent implementation)
4. Identify minor clarifications (nice-to-have but can proceed without)

Output format:
- Completeness score: X/10
- Requirements: [list]
- Non-goals: [list]
- Blocking questions: [list, if any]
- Minor clarifications: [list, if any]

## Acceptance Criteria
Concrete checklist; blocking vs minor questions clearly separated.

---TASK---
id: p1_similar_features
agent: code-explorer
workdir: .
---CONTENT---
## Original User Request
/do <request>

## Current Task
Find 1-3 similar features, trace end-to-end. Return: key files with line numbers, call flow, extension points.

## Acceptance Criteria
Concrete file:line map + reuse points.

---TASK---
id: p1_architecture
agent: code-explorer
workdir: .
---CONTENT---
## Original User Request
/do <request>

## Current Task
Map architecture for relevant subsystem. Return: module map + 5-10 key files.

## Acceptance Criteria
Clear boundaries; file:line references.

---TASK---
id: p1_conventions
agent: code-explorer
workdir: .
---CONTENT---
## Original User Request
/do <request>

## Current Task
Identify testing patterns, conventions, config. Return: test commands + file locations.

## Acceptance Criteria
Test commands + relevant test file paths.

Phase 2: Clarify (Conditional)

Goal: Resolve blocking ambiguities only.

Actions:

1. Review p1_requirements output for blocking questions
2. IF blocking questions exist → Use AskUserQuestion
3. IF no blocking questions (completeness >= 8) → Skip to Phase 3, log "Requirements clear, proceeding"

# Only if blocking questions exist:
# Use AskUserQuestion with the blocking questions from Phase 1

Phase 3: Design (No Interaction)

Goal: Produce minimal-change implementation plan.

Actions: Invoke code-architect with all Phase 1 context to generate a single implementation plan.

codeagent-wrapper --agent code-architect - . <<'EOF'
## Original User Request
/do <request>

## Context Pack
- Code-explorer output: <ALL Phase 1 explorer outputs>
- Code-architect output: <Phase 1 requirements + Phase 2 answers if any>

## Current Task
Design minimal-change implementation:
- Reuse existing abstractions
- Minimize new files
- Follow established patterns from code-explorer output

Output:
- File touch list with specific changes
- Build sequence
- Test plan
- Risks and mitigations

## Acceptance Criteria
Concrete, implementable blueprint with minimal moving parts.
EOF

Phase 4: Implement + Review (Single Interaction Point)

Goal: Build feature and review in one phase.

Actions:

1. Invoke develop to implement (add --worktree if use_worktree: true):

# Check use_worktree from state file, add --worktree if true
codeagent-wrapper --worktree --agent develop - . <<'EOF'
## Original User Request
/do <request>

## Context Pack
- Code-explorer output: <ALL Phase 1 outputs>
- Code-architect output: <Phase 3 blueprint>

## Current Task
Implement with minimal change set following the blueprint.
- Follow Phase 1 patterns
- Add/adjust tests per Phase 3 plan
- Run narrowest relevant tests

## Acceptance Criteria
Feature works end-to-end; tests pass; diff is minimal.
EOF

2. Run parallel reviews (no --worktree needed, read-only):

codeagent-wrapper --parallel <<'EOF'
---TASK---
id: p4_correctness
agent: code-reviewer
workdir: .
---CONTENT---
## Original User Request
/do <request>

## Context Pack
- Code-architect output: <Phase 3 blueprint>
- Develop output: <implementation output>

## Current Task
Review for correctness, edge cases, failure modes.
Classify each issue as BLOCKING or MINOR.

## Acceptance Criteria
Issues with file:line references, severity, and concrete fixes.

---TASK---
id: p4_simplicity
agent: code-reviewer
workdir: .
---CONTENT---
## Original User Request
/do <request>

## Context Pack
- Code-architect output: <Phase 3 blueprint>
- Develop output: <implementation output>

## Current Task
Review for KISS: remove bloat, collapse needless abstractions.
Classify each issue as BLOCKING or MINOR.

## Acceptance Criteria
Actionable simplifications with severity and justification.
EOF

3. Handle review results:
   • MINOR issues only → Auto-fix via develop (with --worktree if enabled), no user interaction
   • BLOCKING issues → Use AskUserQuestion: "Fix now / Proceed as-is"

Phase 5: Complete (No Interaction)

Goal: Document what was built.

Actions: Invoke code-reviewer to produce summary:

codeagent-wrapper --agent code-reviewer - . <<'EOF'
## Original User Request
/do <request>

## Context Pack
- Code-architect output: <Phase 3 blueprint>
- Code-reviewer output: <Phase 4 review outcomes>
- Develop output: <Phase 4 implementation + fixes>

## Current Task
Write completion summary:
- What was built
- Key decisions/tradeoffs
- Files modified (paths)
- How to verify (commands)
- Follow-ups (optional)

## Acceptance Criteria
Short, technical, actionable summary.
EOF

Output the completion signal:

<promise>DO_COMPLETE</promise>
