name: parallel-dispatch type: simple depth: base context: fork user-invocable: false description: >- Orchestrates concurrent workstreams via Task tool for non-trivial requests. Decomposes complex tasks into 3-10 parallel agents with independent scopes and synthesizes results. Use when requests involve: (1) multiple investigative paths or validation layers, (2) research, analysis, or debugging exceeding trivial scope, (3) implementation planning requiring facet exploration, or (4) any moderate+ complexity task benefiting from parallel execution.

[H1][PARALLEL-DISPATCH]

Dictum: Decomposition into concurrent workstreams multiplies throughput on non-trivial tasks.

Orchestrate parallel agents via Task tool.

Workflow:

1. §DECISION — Gate: trivial? decomposable? independent?
2. §DECOMPOSITION — Extract facets, map to agents
3. §AGENT_PROMPT — Structure scope, objective, output, context
4. §DISPATCH — Launch ALL agents in ONE message
5. §SYNTHESIS — Integrate convergent, flag divergent

Exclude: Trivial requests, sequential dependencies, overlapping writes, <3 streams.

[CRITICAL] Dispatch ALL agents in ONE message. Multiple messages execute sequentially—defeats parallelism.

[1][DECISION]

Dictum: Binary gates prevent wasted computation on mismatched patterns.

Request received
    ↓
Trivial? (single lookup, direct action)
    ├─ YES → Execute directly
    └─ NO → Decomposable into independent facets?
              ├─ NO → Execute sequentially
              └─ YES → Verify independence → Dispatch parallel

[VERIFY] Independence confirmed:

• Workstreams share no mutable state
• No stream depends on another's output
• Results synthesize without conflict

[CRITICAL] Gate failure → sequential execution required.

---

[2][DECOMPOSITION]

Dictum: Facet isolation enables contention-free parallel execution.

Extract facets via criteria:

• Independent questions — Resolve distinct aspects of request
• Parallel paths — Accelerate via concurrency
• Validation layers — Strengthen confidence through cross-verification
• Multiple perspectives — Apply sources independently

Agent Count:

• Moderate tasks: 3-5 agents
• Complex tasks: 6-10 agents

[IMPORTANT]:

• [ALWAYS] Map extracted facets to agent assignments.
• [NEVER] Decompose by arbitrary boundaries.
• [NEVER] Create overlapping investigation scope.
• [NEVER] Dispatch single-agent workloads as parallel.

---

[3][AGENT_PROMPT]

Dictum: Precise scope prevents overlap and enables conflict-free synthesis.

Structure each agent prompt:

Scope: [Specific facet—included and excluded elements]
Objective: [Concrete deliverable for this agent]
Output: [Structured format for synthesis]
Context: [Relevant background—agents execute statelessly]

[IMPORTANT]:

• [ALWAYS] Define scope boundaries explicitly—agents receive explicit limits only.
• [ALWAYS] Specify output structure for synthesis.
• [ALWAYS] Include sufficient context—no cross-agent communication.
• [NEVER] Reference other agents or outputs.
• [NEVER] Assume shared context between agents.

---

[4][DISPATCH]

Dictum: Single-message dispatch prevents sequential bottleneck.

[CRITICAL] Dispatch ALL agents in ONE message block:

Task("Agent A: [scope, objective, output format]", subagent_type="Explore")
Task("Agent B: [scope, objective, output format]", subagent_type="Explore")
Task("Agent C: [scope, objective, output format]", subagent_type="general-purpose")
Task("Agent D: [scope, objective, output format]", run_in_background=true)

[IMPORTANT]:

• [ALWAYS] Include complete context per agent—stateless execution.
• [ALWAYS] Specify subagent_type for optimal agent selection.
• [ALWAYS] Use run_in_background=true for long-running tasks.
• [NEVER] Chain agent outputs—parallel means independent.

---

[5][SYNTHESIS]

Dictum: Integration confirms orthogonality and prevents partial results.

Synthesize post-dispatch:

• Convergent findings → High confidence; integrate directly.
• Divergent findings → Flag uncertainty; present alternatives or request resolution.

[CRITICAL] Conflict detected → Decomposition violated orthogonality. Retry sequentially.

[IMPORTANT]:

• [ALWAYS] Verify all agents returned before synthesis.
• [ALWAYS] Flag divergent findings explicitly.

---

[6][VALIDATION]

Dictum: Gates prevent incomplete execution.

[VERIFY] Completion:

• Decision: Independence gates passed (no shared state, no dependencies).
• Decomposition: 3-10 facets mapped to agents.
• Prompts: Scope, objective, output, context defined per agent.
• Dispatch: ALL agents sent in ONE message block.
• Synthesis: Convergent integrated, divergent flagged.
