# Dispatching Parallel Agents

## Overview

When multiple unrelated failures occur (different test files, different subsystems, different bugs), investigating them sequentially wastes time. Each investigation is independent and can happen in parallel.

**Core principle:** Dispatch one agent per independent problem domain. Let them work concurrently.

## When to Use This Skill

Activate this skill when facing:
- **3+ test files failing** with different root causes
- **Multiple subsystems broken** independently
- **Each problem is self-contained** - can be understood without context from others
- **No shared state** between investigations
- **Clear domain boundaries** - fixing one won't affect others

**Don't use when:**
- Failures are related (fix one might fix others)
- Need to understand full system state first
- Agents would interfere with each other (editing same files)
- Exploratory debugging (don't know what's broken yet)

## The Iron Law

```
One agent, one problem domain, one clear outcome.
Never overlap scopes. Never share state. Always integrate consciously.
```

## Core Principles

### Independence is Key
Problems must be truly independent - no shared files, no related root causes, no dependencies between fixes.

### Focus Over Breadth
Each agent gets narrow scope: one test file, one subsystem, one clear goal. Broad tasks lead to confusion.

### Clear Output Required
Every agent must return a summary: what was found, what was fixed, what changed. No silent fixes.

### Conscious Integration
Don't blindly merge agent work. Review summaries, check conflicts, run full suite, verify compatibility.

## Quick Start

### 1. Identify Independent Domains

Group failures by what's broken:
```
File A tests: Tool approval flow
File B tests: Batch completion behavior
File C tests: Abort functionality
```

Each domain is independent - fixing tool approval doesn't affect abort tests.

### 2. Create Focused Agent Tasks

Each agent gets:
- **Specific scope:** One test file or subsystem
- **Clear goal:** Make these tests pass
- **Constraints:** Don't change other code
- **Expected output:** Summary of what you found and fixed

### 3. Dispatch in Parallel

```typescript
// In Claude Code / AI environment
Task("Fix agent-tool-abort.test.ts failures")
Task("Fix batch-completion-behavior.test.ts failures")
Task("Fix tool-approval-race-conditions.test.ts failures")
// All three run concurrently
```

### 4. Review and Integrate

When agents return:
- Read each summary - understand what changed
- Verify fixes don't conflict - check for same file edits
- Run full test suite - ensure compatibility
- Spot check changes - agents can make systematic errors

**→** [troubleshooting.md](references/troubleshooting.md) for conflict resolution

## Decision Tree

```
Multiple failures?
  └→ Are they independent?
      ├→ NO (related) → Single agent investigates all
      └→ YES → Can they work in parallel?
          ├→ NO (shared state) → Sequential agents
          └→ YES → Parallel dispatch ✓
```

## Key Benefits

1. **Parallelization** - Multiple investigations happen simultaneously
2. **Focus** - Each agent has narrow scope, less context to track
3. **Independence** - Agents don't interfere with each other
4. **Speed** - N problems solved in time of 1

### Related Skills

When dispatching parallel agents, consider these complementary skills (available in the skill library):

- **pm-workflow**: PM coordination and task management - manage multiple agent workstreams effectively
- **test-driven-development**: TDD patterns that benefit from parallel fixing - understand test failures before parallelizing
- **verification-before-completion**: Integration verification - ensure parallel agent work integrates correctly

## Key Reminders

1. **Independence is mandatory** - Related failures need single-agent investigation
2. **Focus beats breadth** - Narrow scope per agent prevents confusion
3. **Always verify integration** - Don't blindly merge agent work
4. **Clear outputs required** - Every agent returns summary of changes
5. **Parallelization has overhead** - Only worth it for 3+ independent problems

## Red Flags - STOP

**STOP immediately if:**
- Agents are editing the same files (scope overlap)
- Fixes from one agent break another's work (hidden dependencies)
- Problem domains cannot be clearly separated (not independent)
- Agents return no summary (can't verify changes)
- Integration requires major refactoring (conflicts)

**When in doubt:** Start with one agent, understand the landscape, then dispatch if truly independent.

## Integration with Other Skills

**Prerequisite:** Basic understanding of problem domains and test structure
**Complementary:** PM-Workflow skill for coordinating multiple agents (see skill library)
**Domain-specific:** Testing skills for understanding test failures (available in skill library)

## Real-World Impact

From debugging session (2025-10-03):
- **6 failures** across 3 test files
- **3 agents** dispatched in parallel
- **All investigations** completed concurrently
- **Zero conflicts** between agent changes
- **Time saved:** 3 problems solved in parallel vs sequentially
