## 3. Per-Scanner Detail

### agentshield (v1.4.0) — unavailable / n/a

No findings.

### cisco-skill-scanner (v2.0.11) — Verified / 95.0

- **[low] Vague skill description** — Skill description is too short (16 chars). Provide detailed explanation. (/repo/skills/business-case/SKILL.md:None)
- **[informational] Skill does not specify a license** — Skill manifest does not include a 'license' field. Specifying a license helps users understand usage terms. (/repo/skills/business-case/SKILL.md:None)
- **[low] Vague skill description** — Skill description is too short (16 chars). Provide detailed explanation. (/repo/SKILL.md:None)
- **[informational] Skill does not specify a license** — Skill manifest does not include a 'license' field. Specifying a license helps users understand usage terms. (/repo/SKILL.md:None)

### agent-audit-kit (v0.3.26) — Caution / 84.0

- **[high] Unsigned marketplace.json manifest** — .claude-plugin/marketplace.json lacks a signature or integrity hash field. An attacker with write access to the marketplace can replace the plugin bundle with no detection. (.claude-plugin/marketplace.json:12)
