## 3. Per-Scanner Detail

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

No findings.

### cisco-skill-scanner (v2.0.11) — Verified / 92.0

- **[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/bar-colors/SKILL.md:None)
- **[medium] Moderate analyzability score** — Only 74% of skill content could be analyzed. 2 of 10 files are opaque to the scanner. Some content could not be verified as safe. (/repo: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 / 70.0

- **[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. (marketplace.json:11)
- **[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:11)

### nerlo-behavioral (v0.1.0) — Verified / 100.0

No findings.

### nerlo-install-instruction (v0.1.0) — Verified / 100.0

No findings.

### nerlo-multi-source (v0.1.0) — unavailable / n/a

No findings.

### trivy (v0.71.0) — unavailable / n/a

No findings.

### osv-scanner (v2.3.8) — unavailable / n/a

No findings.

### trivy_image (v0.71.0) — unavailable / n/a

No findings.
