Layer Breakdown
Behavioral Risk Signals
Security Findings1
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| MEDIUM | Excessive permissions for a rubric skill The skill is explicitly declared as a 'security rubric' and its examples are noted as 'non-executable'. However, the skill's manifest declares `Bash(infsh *)` as an allowed tool. A purely informational rubric skill should not require any execution permissions. This broad permission creates an unnecessary attack surface, allowing the agent to potentially execute `infsh` commands if prompted, despite the skill's stated informational purpose. Remove `Bash(infsh *)` from the `allowed-tools` in the skill's manifest. A rubric skill, by definition, should not require execution permissions. | LLM | SKILL.md:1 |
