implementing-code

Executes a batch of implementation tasks with TDD workflow, source-anchored rewrite for behavioral fidelity, guideline-based code transformation, and full requirement tracing. Returns a structured batch report. Triggers: "implement tasks", "execute the batch", "write code for these tasks", "implement with source anchoring", "run the implementation". NOT for: task generation (use breaking-down-tasks), implementation planning (use creating-implementation-plan).
