Execution Guardrails

Agent skill
1 skill

Always-on operational guardrails, model-independent. Apply on EVERY task and EVERY model (Opus, Sonnet, Haiku, and any future tier) whether or not fable-mode's staged loop is running. Three rules: (1) verify-before-flag — never raise a warning about a problem that hasn't been confirmed present by a direct check; (2) warning batching — accumulate minor concerns and surface them together at a threshold instead of interrupting piecemeal; (3) find-and-replace safety — word-boundary anchoring on sed/substring edits plus a corruption grep afterward. Trigger whenever a response would flag a problem, raise a warning, or edit files with search-and-replace. These are behavioral contracts with the user, not capability aids — they do not depend on model strength.
