Risk Level: SAFECOMMAND_EXECUTIONPROMPT_INJECTION
Full Analysis
  • [SAFE]: The skill is a defensive utility that uses a PreToolUse hook to validate bash commands against a set of safety rules defined in rules.json. It provides different operating modes (Careful, Freeze, Unfreeze) to manage operational risk.
  • [COMMAND_EXECUTION]: The skill includes a local bash script (bin/check-dangerous.sh) used as a security gatekeeper. It analyzes commands using standard utilities like jq and grep without executing the commands themselves. The script provides feedback to the agent to prevent execution of blocked patterns.
  • [PROMPT_INJECTION]: The skill exhibits an indirect prompt injection surface by interpolating user-controlled command strings into its warning messages in SKILL.md. While this is inherent to the tool's purpose of reporting what it blocked, it creates a potential channel for malicious commands to attempt to influence the agent's subsequent logic.
  • Ingestion points: Command strings captured by the PreToolUse hook in SKILL.md and bin/check-dangerous.sh.
  • Boundary markers: None present in the SKILL.md warning template.
  • Capability inventory: The skill has the capability to analyze, block, and warn about shell commands using its internal logic and configuration files.
  • Sanitization: Validation is performed through regex pattern matching in rules.json to identify and stop dangerous commands before they are processed by the warning template.
