GOAP Agent Skill: Goal-Oriented Action Planning

Enable intelligent planning and execution of complex multi-step tasks through systematic decomposition, dependency mapping, and coordinated multi-agent execution.

Always use the plans/ folder for all files.

Quick Reference

See the GOAP Agent documentation (../agents/goap-agent.md) for detailed execution patterns and examples.

CRITICAL: Understanding Skills vs Task Agents

There are TWO different types of workers you can coordinate in GOAP planning:

Skills (invoked via Skill tool)

Skills are instruction sets that guide Claude directly. They provide specialized knowledge and workflows.

How to invoke: Skill(command="skill-name")

When to use:

• Need specialized knowledge/workflow guidance
• Task requires deep domain expertise (Rust quality, architecture validation)
• Want to follow a proven methodology
• Examples: Code quality review, gap analysis, architecture validation

Task Agents (invoked via Task tool)

Task Agents are autonomous sub-processes that execute tasks independently using tools.

How to invoke: Task(subagent_type="agent-name", prompt="...", description="...")

When to use:

• Need autonomous task execution
• Task requires tool usage (Read, Edit, Bash, etc.)
• Want parallel/independent execution
• Examples: Running tests, implementing features, debugging

Common Error to Avoid

WRONG: Task(subagent_type="rust-code-quality", ...) → ERROR! rust-code-quality is a Skill!

CORRECT: Skill(command="rust-code-quality") → SUCCESS

See the agent-coordination skill for the complete reference on Skills vs Agents.

When to Use This Skill

Use this skill when facing:

• Complex Multi-Step Tasks: Tasks requiring 5+ distinct steps or multiple specialized capabilities
• Cross-Domain Problems: Issues spanning multiple areas (storage, API, testing, documentation)
• Optimization Opportunities: Tasks that could benefit from parallel or hybrid execution
• Quality-Critical Work: Projects requiring validation checkpoints and quality gates
• Resource-Intensive Operations: Large refactors, migrations, or architectural changes
• Ambiguous Requirements: Tasks needing structured analysis before execution

Core GOAP Methodology

The GOAP Planning Cycle

1. ANALYZE → Understand goals, constraints, resources
2. DECOMPOSE → Break into atomic tasks with dependencies
3. STRATEGIZE → Choose execution pattern (parallel/sequential/swarm/hybrid/iterative)
4. COORDINATE → Assign tasks to specialized agents
5. EXECUTE → Run with monitoring and quality gates
6. SYNTHESIZE → Aggregate results and validate success

Phase 1: Task Analysis

Initial Assessment

## Task Analysis

**Primary Goal**: [Clear statement of what success looks like]

**Constraints**:
- Time: [Urgent / Normal / Flexible]
- Resources: [Available agents, tools, data]
- Dependencies: [External systems, prerequisites]

**Complexity Level**:
- Simple: Single agent, <3 steps
- Medium: 2-3 agents, some dependencies
- Complex: 4+ agents, mixed execution modes
- Very Complex: Multiple phases, many dependencies

**Quality Requirements**:
- Testing: [Unit / Integration / E2E]
- Standards: [AGENTS.md compliance, formatting, linting]
- Documentation: [API docs, examples, guides]
- Performance: [Speed, memory, scalability]

Context Gathering

1. Codebase Understanding: Use Explore agent to understand relevant code
2. Past Patterns: Check if similar tasks have been done before
3. Available Resources: Identify available agents and their capabilities
4. Current State: Understand starting conditions and existing implementations

Phase 2: Task Decomposition

Use the task-decomposition skill to break down the goal:

## Task Decomposition: [Task Name]

### Main Goal
[Clear statement of primary objective]

### Sub-Goals
1. [Component 1] - Priority: P0
   - Success Criteria: [How to verify]
   - Dependencies: [Prerequisites]
   - Complexity: [Low/Medium/High]

2. [Component 2] - Priority: P1
   - Success Criteria: [How to verify]
   - Dependencies: [Component 1]
   - Complexity: [Low/Medium/High]

### Atomic Tasks
**Component 1: [Name]**
- Task 1.1: [Action] (Agent: type, Deps: none)
- Task 1.2: [Action] (Agent: type, Deps: 1.1)

### Dependency Graph

Task 1.1 → Task 1.2 → Task 2.1 ↘ Task 1.3 (parallel) → Task 2.2

Key Decomposition Principles

• Atomic: Each task is indivisible and clear
• Testable: Can verify completion
• Independent where possible: Minimize dependencies
• Assigned: Each task maps to an agent capability

Phase 3: Strategy Selection

Choose execution strategy based on task characteristics. See the GOAP Agent documentation (../agents/goap-agent.md) for detailed execution patterns.

Quick Strategy Guide

| Strategy | When to Use | Speed | Complexity | |----------|-------------|-------|------------| | Parallel | Independent tasks, time-critical | Nx | High | | Sequential | Dependent tasks, order matters | 1x | Low | | Swarm | Many similar tasks | ~Nx | Medium | | Hybrid | Mixed requirements | 2-4x | Very High | | Iterative | Progressive refinement, convergence | Varies | Medium |

Decision Tree

Needs iterative refinement?
  ├─ Yes (until criteria met or converged) → ITERATIVE
  └─ No → Is time critical?
      ├─ Yes → Can tasks run in parallel?
      │   ├─ Yes → PARALLEL
      │   └─ No → SEQUENTIAL (prioritize critical path)
      └─ No → Are tasks similar?
          ├─ Yes (many similar) → SWARM
          ├─ No (mixed) → HYBRID
          └─ Simple linear → SEQUENTIAL

Phase 4: Agent Assignment

Agent Capability Matrix

| Agent Type | Capabilities | Tools Available | Best For | |------------|--------------|-----------------|----------| | feature-implementer | Design, implement, test, integrate features | Read, Write, Edit, Bash, Glob, Grep | New functionality, modules, APIs | | debugger | Diagnose runtime issues, async problems | Read, Bash, Grep, Edit | Bug fixes, deadlocks, performance | | test-runner | Execute tests, diagnose failures | Bash, Read, Grep, Edit | Test validation, debugging tests | | refactorer | Improve structure, eliminate duplication | Read, Edit, Bash, Grep, Glob | Code quality, modernization | | code-reviewer | Review quality, standards, security | Read, Glob, Grep, Bash | Quality assurance, pre-commit | | loop-agent | Iterative refinement, convergence | Task, Read, TodoWrite, Glob, Grep | Progressive improvements, test-fix loops | | agent-creator | Create new Task Agents | Write, Read, Glob, Grep, Edit | Building new autonomous capabilities | | Explore | Fast codebase exploration | All tools | Finding files, understanding architecture | | memory-cli | CLI development and testing | Read, Write, Edit, Bash, Glob, Grep | Memory CLI features and fixes |

Assignment Principles

1. Match agent capabilities to task requirements
2. Balance workload across agents
3. Consider agent specialization
4. Plan for quality validation

Error Handling & Recovery

Agent Failure Recovery

**If agent fails:**

2. Check quality gate status
3. Options:
   - Retry same agent (transient error)
   - Assign to different agent (agent issue)
   - Modify task (requirements issue)
   - Escalate to user (blocking issue)

Quality Gate Failure

**If quality gate fails:**
1. Identify failing criteria
2. Diagnose root cause
3. Options:
   - Re-run previous phase with fixes
   - Adjust quality criteria (if appropriate)
   - Change strategy (e.g., parallel → sequential for debugging)

Blocked Dependencies

**If dependency blocks progress:**
1. Identify blocking task
2. Prioritize unblocking
3. Options:
   - Execute dependency first (re-order)
   - Remove dependency (refactor plan)
   - Parallel work on independent tasks

Best Practices

DO:

✓ Break tasks into atomic, testable units ✓ Define clear quality gates between phases ✓ Match agent capabilities to task requirements ✓ Monitor progress and validate incrementally ✓ Document decisions and rationale ✓ Learn from execution for future planning ✓ Use parallel execution where safe ✓ Validate dependencies before execution

DON'T:

✗ Create monolithic tasks (break them down) ✗ Skip quality gates (leads to cascading failures) ✗ Assume tasks are independent (verify carefully) ✗ Ignore agent failures (address immediately) ✗ Over-complicate simple tasks (use sequential) ✗ Under-estimate coordination overhead ✗ Forget to aggregate and synthesize results

Integration with Other Skills

• task-decomposition: Use for Phase 2 (breaking down complex goals)
• agent-coordination: Use for Phase 6 (coordinating multiple agents)
• parallel-execution: Use for parallel strategy implementation
• loop-agent: Use for iterative refinement strategy implementation
• All specialized agents (feature-implementer, debugger, test-runner, etc.)
