[H1][PARALLEL-DISPATCH]

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

<br>

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.

<br>

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.

<br>

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.

<br>

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.

<br>

[CRITICAL] Dispatch ALL agents in ONE message block. Call multiple Task tools in a single response:

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

Tool Parameters:

[INDEX]	[PARAMETER]	[TYPE]	[REQUIRED]	[DESCRIPTION]
[1]	description	string	Yes	Full agent prompt with scope, objective, output format
[2]	subagent_type	string	No	"Explore" for research; omit for general-purpose

Agent Type Selection:

[INDEX]	[TYPE]	[ACCESS]	[USE_WHEN]
[1]	"Explore"	Glob, Grep, Read, WebFetch	Codebase search, file analysis, web research
[2]	(omit/default)	All tools	General tasks, file creation, code modification

[IMPORTANT]:

• [ALWAYS] Include complete context per agent — stateless execution.
• [ALWAYS] Use subagent_type="Explore" for codebase/research tasks needing Glob, Grep, Read access.
• [ALWAYS] Place ALL Task tool calls in a single response — parallel execution requires single message.
• [NEVER] Chain agent outputs — parallel means independent.
• [NEVER] Use placeholder values — each agent prompt must be self-contained.

---

[5][SYNTHESIS]

Dictum: Integration confirms orthogonality and prevents partial results.

<br>

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.

<br>

[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.
