Layer Breakdown
Behavioral Risk Signals
Security Findings1
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| HIGH | Excessive permissions declared for a 'patterns' skill The skill 'powershell-windows' is described as providing 'PowerShell Windows patterns. Critical pitfalls, operator syntax, error handling.' However, its manifest declares broad permissions including 'Read, Write, Edit, Glob, Grep, Bash'. A skill focused on providing instructional patterns or guidance typically does not require the ability to modify files, glob, grep, or execute arbitrary bash commands. The 'Bash' permission, in particular, grants significant control over the host system, which is disproportionate to the skill's stated purpose and introduces a high risk if the skill were to be compromised or misused. Review and reduce the declared 'allowed-tools' to only those strictly necessary for the skill's intended functionality. For a skill providing patterns/guidance, 'Read' might be minimally justifiable, but 'Write', 'Edit', 'Glob', 'Grep', and 'Bash' are likely excessive and should be removed unless a clear, secure use case is identified. | LLM | SKILL.md:1 |
