Orchestrating Work (Two-Tier Agent Pattern)

Decompose complex requests into focused subtasks and delegate each to a specialist worker subagent.

Core principle: Manager plans and delegates. Workers execute. Manager synthesizes.

When to Use

digraph when_to_use {
    "Complex multi-part task?" [shape=diamond];
    "Benefits from specialization?" [shape=diamond];
    "Use orchestrating-work" [shape=box];
    "Handle directly" [shape=box];

    "Complex multi-part task?" -> "Benefits from specialization?" [label="yes"];
    "Complex multi-part task?" -> "Handle directly" [label="no - simple"];
    "Benefits from specialization?" -> "Use orchestrating-work" [label="yes"];
    "Benefits from specialization?" -> "Handle directly" [label="no"];
}

Use when:

• Task has 3+ distinct subtasks
• Different skills needed (research, code, review)
• Subtasks can be defined independently
• Quality benefits from focused attention

Don't use when:

• Task is straightforward
• Heavy interdependencies between parts
• Exploratory work (don't know scope yet)

The Pattern

Phase 1: Analyze & Plan (You are the Manager)

Before delegating, decompose the request:

1. Identify objectives - What outcomes does the user need?
2. Break into subtasks - Each should be atomic and focused
3. Assign workers - Match subtask to specialist:

- coder - Write, modify, debug code - researcher - Investigate, analyze, recommend - reviewer - Evaluate quality, find issues

1. Order execution - Sequential if dependencies, parallel if independent
2. Define done - Measurable criteria for completion

Phase 2: Delegate (Dispatch Worker Subagents)

For each subtask, dispatch a worker using the Task tool:

Task tool (general-purpose):
  description: "[Worker]: [brief task]"
  prompt: [Use worker prompt template from ./workers/]

Worker prompt templates:

• ./workers/coder-prompt.md - Implementation tasks
• ./workers/researcher-prompt.md - Investigation tasks
• ./workers/reviewer-prompt.md - Quality review tasks

Phase 3: Synthesize (Verify & Integrate)

After workers return:

1. Review each result - Did worker complete successfully?
2. Check for INCAPABLE - Reassign or handle differently
3. Verify integration - Do results work together?
4. Check Definition of Done - All criteria met?
5. Report to user - Summary with artifacts

Example Workflow

User: "Create a rate limiter middleware for Express with sliding window"

--- PHASE 1: PLAN ---

Objectives:
1. Functional rate limiter middleware
2. Sliding window algorithm (not fixed window)
3. Configurable limits
4. Proper HTTP responses

Subtasks:
1. [researcher] Research sliding window algorithms for rate limiting
2. [coder] Implement the middleware based on research
3. [reviewer] Review implementation for edge cases and security

Execution: Sequential (2 depends on 1, 3 depends on 2)

Definition of Done:
- Middleware limits requests per IP
- Uses sliding window (not fixed)
- Configurable time window and max requests
- Returns 429 with Retry-After header
- Handles edge cases (no IP, concurrent requests)

--- PHASE 2: DELEGATE ---

[Dispatch researcher subagent with ./workers/researcher-prompt.md]
Researcher returns: Analysis of token bucket vs sliding window log vs sliding window counter...

[Dispatch coder subagent with ./workers/coder-prompt.md + researcher findings]
Coder returns: Implementation + tests

[Dispatch reviewer subagent with ./workers/reviewer-prompt.md]
Reviewer returns: Review with findings

--- PHASE 3: SYNTHESIZE ---

✓ Researcher provided algorithm recommendation
✓ Coder implemented with tests passing
✓ Reviewer approved (minor suggestions addressed)
✓ All Definition of Done criteria met

[Report to user with code artifact]

Key Principles

Manager Responsibilities

• Never do the work - Only plan, delegate, verify
• Provide context - Workers get what they need upfront
• Define scope clearly - Workers know exactly what to do
• Verify completion - Check against Definition of Done

Worker Characteristics

• Stateless - Only know their subtask, not full request
• Focused - One clear goal, one specialty
• Honest - Report INCAPABLE if task doesn't fit
• Structured output - Return results in expected format

Communication

• Manager provides full context to workers
• Workers don't read the original request
• Workers return structured results
• Manager integrates everything

Red Flags

❌ Manager doing work: If you're writing code or researching, stop. Delegate. ❌ Vague subtasks: "Handle the backend" → Be specific about what to build ❌ Missing context: Worker asks questions → You didn't provide enough upfront ❌ Skipping review: Always have a reviewer check code ❌ Ignoring INCAPABLE: Worker said they can't → Reassign or rethink

Integration with Other Skills

Works well with:

• bach:lifecycle - For multi-phase projects with review gates. Lifecycle wraps this skill — each phase executes using the two-tier pattern here, with gates between phases.
• superpowers:writing-plans - For larger initiatives, write plan first
• superpowers:test-driven-development - Coder workers should follow TDD
• superpowers:dispatching-parallel-agents - When subtasks are independent

Sequence:

1. Use lifecycle if task spans multiple phases with gates
2. Use orchestrating-work for single-pass decomposition
3. Workers use test-driven-development for code tasks
