name	do
description	This skill should be used for structured feature development with codebase understanding. Triggers on /do command. Provides a 7-phase workflow (Discovery, Exploration, Clarification, Architecture, Implementation, Review, Summary) using codeagent-wrapper to orchestrate code-explorer, code-architect, code-reviewer, and develop agents in parallel.

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>, first initialize the loop state:

"${SKILL_DIR}/scripts/setup-do.sh" "<task description>"

This creates .claude/do.local.md with:

• active: true
• current_phase: 1
• max_phases: 7
• completion_promise: "<promise>DO_COMPLETE</promise>"

Loop State Management

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

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

When all 7 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. Phase 3 (Clarification) is mandatory. Do not proceed until questions are answered.
3. Phase 5 (Implementation) requires explicit approval. Stop after Phase 4 if not approved.
4. Pass complete context forward. Every agent invocation includes the Context Pack.
5. Parallel-first. Run independent tasks via codeagent-wrapper --parallel.
6. Update state after each phase. Keep .claude/do.local.md current.

Agents

Agent	Purpose	Prompt
code-explorer	Trace code, map architecture, find patterns	agents/code-explorer.md
code-architect	Design approaches, file plans, build sequences	agents/code-architect.md
code-reviewer	Review for bugs, simplicity, conventions	agents/code-reviewer.md
develop	Implement code, run tests	(uses global config)

7-Phase Workflow

Phase 1: Discovery

Goal: Understand what to build.

Actions:

1. Use AskUserQuestion for: user-visible behavior, scope, constraints, acceptance criteria
2. Invoke code-architect to draft requirements checklist and clarifying questions

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

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

## Current Task
Produce requirements checklist and identify missing information.
Output: Requirements, Non-goals, Risks, Acceptance criteria, Questions (<= 10)

## Acceptance Criteria
Concrete, testable checklist; specific questions; no implementation.
EOF

Phase 2: Exploration

Goal: Map codebase patterns and extension points.

Actions: Run 2-3 code-explorer tasks in parallel (similar features, architecture, tests/conventions).

codeagent-wrapper --parallel <<'EOF'
---TASK---
id: p2_similar_features
agent: code-explorer
workdir: .
---CONTENT---
## Original User Request
/do <request>

## Context Pack
- Code-architect output: <Phase 1 output>

## 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: p2_architecture
agent: code-explorer
workdir: .
---CONTENT---
## Original User Request
/do <request>

## Context Pack
- Code-architect output: <Phase 1 output>

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

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

---TASK---
id: p2_conventions
agent: code-explorer
workdir: .
---CONTENT---
## Original User Request
/do <request>

## Context Pack
- Code-architect output: <Phase 1 output>

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

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

Phase 3: Clarification (MANDATORY)

Goal: Resolve all ambiguities before design.

Actions:

1. Invoke code-architect to generate prioritized questions from Phase 1+2 outputs
2. Use AskUserQuestion to present questions and wait for answers
3. Do not proceed until answered or defaults accepted

Phase 4: Architecture

Goal: Produce implementation plan fitting existing patterns.

Actions: Run 2 code-architect tasks in parallel (minimal-change vs pragmatic-clean).

codeagent-wrapper --parallel <<'EOF'
---TASK---
id: p4_minimal
agent: code-architect
workdir: .
---CONTENT---
## Original User Request
/do <request>

## Context Pack
- Code-explorer output: <ALL Phase 2 outputs>
- Code-architect output: <Phase 1 + Phase 3 answers>

## Current Task
Propose minimal-change architecture: reuse existing abstractions, minimize new files.
Output: file touch list, risks, edge cases.

## Acceptance Criteria
Concrete blueprint; minimal moving parts.

---TASK---
id: p4_pragmatic
agent: code-architect
workdir: .
---CONTENT---
## Original User Request
/do <request>

## Context Pack
- Code-explorer output: <ALL Phase 2 outputs>
- Code-architect output: <Phase 1 + Phase 3 answers>

## Current Task
Propose pragmatic-clean architecture: introduce seams for testability.

## Acceptance Criteria
Implementable blueprint with build sequence and tests.
EOF

Use AskUserQuestion to let user choose approach.

Phase 5: Implementation (Approval Required)

Goal: Build the feature.

Actions:

1. Use AskUserQuestion: "Approve starting implementation?" (Approve / Not yet)
2. If approved, invoke develop:

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

## Context Pack
- Code-explorer output: <ALL Phase 2 outputs>
- Code-architect output: <selected Phase 4 blueprint + Phase 3 answers>

## Current Task
Implement with minimal change set following chosen architecture.
- Follow Phase 2 patterns
- Add/adjust tests per Phase 4 plan
- Run narrowest relevant tests

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

Phase 6: Review

Goal: Catch defects and unnecessary complexity.

Actions: Run 2-3 code-reviewer tasks in parallel (correctness, simplicity).

codeagent-wrapper --parallel <<'EOF'
---TASK---
id: p6_correctness
agent: code-reviewer
workdir: .
---CONTENT---
## Original User Request
/do <request>

## Context Pack
- Code-architect output: <Phase 4 blueprint>
- Develop output: <Phase 5 output>

## Current Task
Review for correctness, edge cases, failure modes. Assume adversarial inputs.

## Acceptance Criteria

EOF

Use AskUserQuestion: Fix now / Fix later / Proceed as-is.

Phase 7: Summary

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 4 blueprint>
- Code-reviewer output: <Phase 6 outcomes>
- Develop output: <Phase 5 output + fixes>

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

## Acceptance Criteria
