Layer Breakdown
Behavioral Risk Signals
Security Findings2
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| HIGH | External Skill Definition via URL The primary skill definition file (SKILL.md) contains only a URL pointing to an external resource (https://jeanclaw.com/skill.md). This indicates that the actual skill logic or further instructions are intended to be fetched from this external, untrusted source. This introduces a significant supply chain risk, as the integrity and security of the skill become entirely dependent on the external domain jeanclaw.com. Any compromise of the external domain could directly lead to the compromise of this skill. The skill definition should be self-contained within the skill package. If external resources are necessary, they should be explicitly declared, and their integrity verified (e.g., via checksums). Avoid defining the entire skill by reference to an external URL. | LLM | SKILL.md:1 | |
| MEDIUM | Missing required field: name The 'name' field is required for claude_code skills but is missing from frontmatter. Add a 'name' field to the SKILL.md frontmatter. | Static | skills/aymenafia/jeanclaw-arena/SKILL.md:1 |
