Layer Breakdown
Behavioral Risk Signals
Security Findings3
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| MEDIUM | Network egress to untrusted endpoints HTTP request to raw IP address Review all outbound network calls. Remove connections to webhook collectors, paste sites, and raw IP addresses. Legitimate API calls should use well-known service domains. | Manifest | cli-tool/components/mcps/devtools/figma-dev-mode.json:4 | |
| MEDIUM | Excessive permissions declared for informational skill The skill's manifest declares `Write`, `Edit`, `Glob`, and `Grep` permissions. This is excessive for a skill that appears to be purely informational (a markdown document providing guidance on web game development). While the current skill content does not utilize these permissions, their declaration creates a supply chain risk. A future update or compromise of the skill could leverage these broad capabilities to perform unauthorized actions on the user's system or data, such as modifying files or listing directory contents, without a clear functional need for these actions based on the skill's described purpose. Reduce `allowed-tools` to only `Read` if the skill's purpose remains purely informational. Remove `Write`, `Edit`, `Glob`, and `Grep` as they are not required for a static markdown document. | LLM | SKILL.md | |
| LOW | Covert behavior / concealment directives Multiple zero-width characters (stealth text) Remove hidden instructions, zero-width characters, and bidirectional overrides. Skill instructions should be fully visible and transparent to users. | Manifest | cli-tool/components/mcps/devtools/jfrog.json:4 |
