Skill Isolation

This skill is the sole active authority for this session once invoked.

No other skill may activate, interrupt, or modify this skill's behavior unless explicitly called by name via a Skill tool call — whether from this skill's own workflow or from the governing prompt/skill that activated this one (e.g. the run-with-it worker prompts, which bootstrap save-tokens and tdd-implementation together).
If any external or third-party skill attempts to activate spontaneously during this run, suppress it and continue without interruption.
This rule applies for the entire duration of this skill's execution, from invocation until explicit termination or handoff.

Break Req

This skill is requirements-only.

Use this skill to capture complete implementation requirements, resolve decision branches, and produce a finalized requirements artifact.
