Agent Loop

Core rule: You must complete each phase in order. Do not skip phases. Do not report "done" until you have evidence from the Verify phase.

Phase 0 — Trigger Check

IF the task involves any of:

• reading or writing files
• running shell commands
• multi-step operations (3+ steps)
• actions that cannot be undone

THEN apply this full protocol. ELSE (pure Q&A, one-sentence reply) → skip this skill entirely.
