someiyoshino-labandGitHub 4a4fa907f5 docs(rules): add Delegation Completion Contract to agent orchestration rules (#2471)
The 'Parallel Task Execution' rule encourages agents to spawn subagents,
but defines no completion contract. Observed failure mode: subagents
followed the rule, spawned their own children, and returned 'waiting
for background agents' as their final answer. All children completed
successfully, but their results were orphaned because a parent whose
turn has ended cannot receive completion notifications - leaving
zombie 'running' tasks and lost work.

Adds three rules that apply at every delegation depth:
1. Your final message IS the deliverable (never end with 'waiting')
2. If you delegate, you own collection (no fire-and-forget)
3. Decompose only when work cannot fit in one context

# Agent Orchestration
## Available Agents
Located in `~/.claude/agents/`:
| Agent | Purpose | When to Use |
|-------|---------|-------------|
| planner | Implementation planning | Complex features, refactoring |
| architect | System design | Architectural decisions |
| tdd-guide | Test-driven development | New features, bug fixes |
| code-reviewer | Code review | After writing code |
| security-reviewer | Security analysis | Before commits |
| build-error-resolver | Fix build errors | When build fails |
| e2e-runner | E2E testing | Critical user flows |
| refactor-cleaner | Dead code cleanup | Code maintenance |
| doc-updater | Documentation | Updating docs |
| rust-reviewer | Rust code review | Rust projects |
| harmonyos-app-resolver | HarmonyOS app development | HarmonyOS/ArkTS projects |
## Immediate Agent Usage
No user prompt needed:
1. Complex feature requests - Use **planner** agent
2. Code just written/modified - Use **code-reviewer** agent
3. Bug fix or new feature - Use **tdd-guide** agent
4. Architectural decision - Use **architect** agent
## Parallel Task Execution
ALWAYS use parallel Task execution for independent operations:
```markdown
# GOOD: Parallel execution
Launch 3 agents in parallel:
1. Agent 1: Security analysis of auth module
2. Agent 2: Performance review of cache system
3. Agent 3: Type checking of utilities
# BAD: Sequential when unnecessary
First agent 1, then agent 2, then agent 3
```
## Delegation Completion Contract
Applies to every agent at every depth (parent, child, grandchild):
1. **Your final message IS the deliverable.** Never end your turn with "waiting for background agents" — a spawned task is not a completed task. Ending your turn while children are running orphans their results (completed children cannot notify a parent whose turn has ended).
2. **If you delegate, you own collection.** Wait for results, integrate them, then return. Fire-and-forget delegation is forbidden.
3. **Decompose only when the work cannot fit in one context.** Do not re-delegate a task already sized for a single agent — depth is an outcome, not a plan.
> Rationale: observed failure mode — research agents followed "Parallel Task Execution" above, spawned children, and returned "waiting" as their final answer. All children completed successfully but their results were orphaned. The parallel rule without a completion contract produces zombie tasks.
## Multi-Perspective Analysis
For complex problems, use split role sub-agents:
- Factual reviewer
- Senior engineer
- Security expert
- Consistency reviewer
- Redundancy checker
