Work

Deliver the requested implementation with the smallest coordination structure that gets to a verified result.

Contract

Treat $ARGUMENTS and the conversation as the scope and success criteria. Ask only when a missing decision changes scope, safety, implementation, or verification.
Preserve unrelated work and repository conventions. Do not add features, cleanup, abstractions, or compatibility layers outside the request.
Use subagents only when the environment supports them and at least two bounded tracks can proceed independently with distinct ownership and acceptance criteria. File count alone does not justify delegation.
Keep integration decisions with the coordinating agent. Verify the combined result, not merely each track in isolation.
