Sensitive filesystem path referenced
The skill references a path (`~\/\.ssh\/`) that contains credentials or system secrets. Reading this from an unsandboxed skill is a credential-exfiltration vector.

106**Structural attacks** (check scanner output for these):
107- **Symlinks**: Files that resolve outside the skill directory — can disguise reads of `~/.ssh/id_rsa`, `~/.aws/credentials`, etc. as "example" files← sensitive path — credential-exfiltration vector
108- **Frontmatter hooks**: `PostToolUse`/`PreToolUse` hooks in YAML — execute shell commands automatically, the model cannot prevent it
109- **`!`command`` syntax**: Runs shell commands at skill load time during template expansion, before the model sees the prompt
med
No capability manifest declared
The skill ships without a `manifest.yaml` or `capabilities` block in its frontmatter. Without a manifest, the runtime cannot enforce what this skill is permitted to do.
