Fleet Mission

Activates when a task requires launching multiple agents in parallel to cover different aspects of the same work.

When to Use

• Research requiring 3+ parallel investigation tracks
• Document expansion across multiple files simultaneously
• Fact-checking large document sets
• Data gathering from multiple sources
• Any work that decomposes into independent parallel units

Dispatch Pattern

1. DECOMPOSE work into N independent units
2. LAUNCH agents in a single message (parallel tool calls)
3. Use run_in_background: true for all agents
4. MONITOR — agents report back via task notifications
5. AGGREGATE results as agents complete
6. COMMIT incrementally — don't wait for all to finish

Fleet Sizing

Rules

• Maximum 5-6 agents per fleet (diminishing returns beyond that)
• Each agent gets a COMPLETE brief — they have no shared context
• Use worktree isolation for agents that write files
• Commit results incrementally as agents complete — don't batch
• Always have a fallback plan to write directly if an agent fails

Worktree Management

Agents in worktrees write to isolated copies. After completion:

cp worktree-path/output/file.md main-repo/output/file.md

Then commit from the main repo branch.

Proven Scale

• 4 parallel document-builder agents: HEL expansion (20K → 79K words)
• 5 parallel deep-research agents: OOPS fleet (5 docs, ~16K words)
• 4 parallel research agents: HEL refinement (He-3, shortage history, Silicon Forest, regulatory)
• 3 parallel data-gathering agents: HEL data fidelity (market, space, PNW)
