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 within this skill's own workflow.
• 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.
