BF guardian

Mandatory safety gatekeeper for AI agents performing destructive operations. Intercepts file deletion (rm/del/remove), database modifications (writes/deletes/drops), mass file operations (>10 files), system-level changes (service modifications, firewall rules), and external transmissions with side effects (email, API calls to unknown endpoints, mass messaging). Enforces backup verification before destructive execution. If backup is active and verified, low-risk operations proceed without delay. If no backup or risk is high, escalates to human approval. Use when an AI agent is about to execute an operation that irreversibly modifies, deletes, or transmits data or system configuration. Does NOT trigger on read-only operations, non-destructive edits with undo capability, or operations inside temporary/sandbox directories.

How to improve

  1. The text references files that are not there: add them or drop the references.
For the model run — optional
  • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
  • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.

Quality signals

  • +5Description has no quoted example phrases that should trigger the skill
  • +4Description does not say when NOT to use the skill (false activations)
  • +3Description length 830: 120–800 characters recommended
  • +3Output format is not stated: the model decides each time
  • +1No license

Quality base 70; lint remarks subtract, signals add up to 100. Result: 74.

External checks

ClawHub: suspicious
Guardian is a safety-focused skill, but its own rules are inconsistent in ways that could let destructive actions proceed without the human approval users would expect.
