Implementation Subagents

Fresh subagent per task. One combined review per completed batch. Parallel when independent, sequential when dependent.

When to Use Subagents

Use when (all must hold):

• The design is settled: the plan or design.md already specifies what the file contains (types, signatures, schema, contract, or an existing pattern to copy)
• The work item has explicit requirements, owned files, and a validation command
• It does not share files or state with other in-flight work

Prime candidates are new files, scaffolding, boilerplate, and pattern-following edits. Parallelism is a separate question: dispatch two or more eligible items concurrently only when the independence check below passes.
