Run backend-backed live safety checks

Use this skill to gate instructions that may trigger tools or state changes behind a backend-backed safety decision before execution.

This skill is for live instruction and operation safety only. For pre-install repository auditing, use skill-audit.

Maintainer-only validation assets are excluded from ClawHub uploads.

Scope

• Included:
  • live instruction safety checks through scripts/safety.py
  • backend-backed retry/error normalization for pre-execution decisions
• Not included:
  • pre-install repository auditing (skill-audit)
  • content masking or restoration workflows (privacy-protector)
  • request/response gateway routing (modeio-middleware)

Working directory

Run these commands from inside the security folder.

Requirements

• Hard requirement: python3
• Required package for successful live checks: requests
• Required runtime condition: network reachability to the safety backend
• Optional override: SAFETY_API_URL

Core commands

python3 scripts/safety.py -i "Delete /tmp/cache/build-123.log" \
  -c '{"environment":"local-dev","operation_intent":"cleanup","scope":"single-resource","data_sensitivity":"internal","rollback":"easy","change_control":"none"}' \
  -t "/tmp/cache/build-123.log" --json

python3 scripts/safety.py -i "DROP TABLE users" \
  -c '{"environment":"production","operation_intent":"destructive","scope":"broad","data_sensitivity":"regulated","rollback":"none","change_control":"ticket:DB-9021"}' \
  -t "postgres://prod/maindb.users" --json

Context contract

Pass --context as JSON with these keys when the instruction may change state:

{
  "environment": "local-dev|ci|staging|production|unknown",
  "operation_intent": "read-only|cleanup|maintenance|migration|permission-change|destructive|unknown",
  "scope": "single-resource|bounded-batch|broad|unknown",
  "data_sensitivity": "public|internal|sensitive|regulated|unknown",
  "rollback": "easy|partial|none|unknown",
  "change_control": "ticket:<id>|approved-manual|none|unknown"
}

--target should be a concrete resource identifier such as an absolute path, table name, service name, or URL.

Runtime notes

• Success envelope: success, tool, mode, data
• Error envelope: success, tool, mode, error
• Error types: validation_error, dependency_error, network_error, api_error
• For state-changing work, provide both --context and --target so the backend has enough context to judge risk
• If the check fails with network/API/dependency issues, do not silently proceed
• The CLI forwards the request and returns the backend result; it does not locally enforce caller policy

Caller policy guidance

approved	risk_level	Agent action
true	low	Proceed.
true	medium	Proceed and mention the risk.
false	medium	Require explicit confirmation before proceeding.
false	high	Block by default and require explicit override.
false	critical	Block and require explicit acknowledgement before any override.

Resources

• scripts/safety.py — live safety check entry point
• ARCHITECTURE.md — command-safety package boundaries

When not to use

• Pre-install or repository-level inspection that should happen before any execution attempt
• Pure planning, summarization, or clearly read-only analysis with no tool call or state-change path
• Data transformation tasks that need to rewrite or mask content rather than score runtime safety
• Local routing or middleware scenarios where you need to sit in front of upstream model traffic
