delegate

Do NOT pass conversation history, prior subagent results, or orchestrator reasoning to subagents. Include only the task scope, relevant code context, constraints, and output format.

Delegate

Dispatch subagents for isolated work. You think, they execute.

Default: Delegate

Prefer subagents over inline work. They protect orchestrator context and produce parallelism for free. The model spawns fewer subagents than prior generations by default — push back against that drift. If a task fits the shape, dispatch.

Delegate when any of these hold:

• 2+ independent tasks that can run without shared state
• Heavy implementation where context isolation benefits you
• Investigations whose intermediate output you won't need again (codebase surveys, docs reading, spec verification)
• Fresh perspective (no session baggage) is an advantage
• You only need the conclusion, not the raw tool outputs that produced it

Stay inline only when:

• You need to reason over the raw tool outputs, not just the conclusion
• The task is tightly coupled to other in-flight changes touching the same files
• The work requires judgment calls or architectural decisions you shouldn't hand off

When in doubt, delegate.

Prompt Construction

Use the template at delegation-prompt.md in this directory as a base.

Include:

• Specific scope and clear goal
• All code and context the subagent needs (paste it — don't point to files)
• Constraints (what NOT to touch, what NOT to change)
• Expected output format
• If mid-execution on a spec: the spec file path. The subagent reads User Constraints and the Progress Log to pick up state without inheriting your conversation.

Exclude:

• Conversation history
• Prior review results
• Your reasoning about the problem
• Other subagents' results

Always include this in the prompt:

Begin your response with one of: STATUS: DONE, STATUS: DONE_WITH_CONCERNS, STATUS: NEEDS_CONTEXT, or STATUS: BLOCKED. Then report: what you did, files changed, and any concerns.

Handling Results

• DONE: Verify independently — check the diff, run tests. Never trust the report alone.
• DONE_WITH_CONCERNS: Read concerns first. If about correctness or scope, address before proceeding.
• NEEDS_CONTEXT: Provide missing info, re-dispatch.
• BLOCKED: If context problem, provide more. If too complex, break it down. If the plan is wrong, consult the user.

Narrow Decomposition Check

Before dispatching, verify your decomposition covers the full scope. If you only assign 3 subtopics when there are 5, the missing 2 will never get done. Enumerate broadly, then verify coverage.

Model Selection

Match capability to task complexity:

• Mechanical tasks (isolated functions, clear specs, 1-2 files): fastest available model
• Integration tasks (multi-file, pattern matching): standard model
• Architecture and review tasks: most capable model

When the platform supports it, consider using lower effort settings for mechanical subagents — they don't need deep thinking for straightforward implementation work.

Integration

• Predecessors: execute, or direct invocation
• Successors: Returns to caller
• May invoke: —
