SkillShield's automated analysis identified 2 findings: 0 critical, 1 high, 1 medium, and 0 low severity. Key findings include Missing required field: name, Unrestricted local file access via 'upload' and 'download' tools.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. All layers scored 70 or above, reflecting consistent security practices.
Last analyzed on February 13, 2026 (commit 13146e6a). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings2
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| HIGH | Unrestricted local file access via 'upload' and 'download' tools The 'upload' and 'download' tools, as defined in the skill's manifest, allow specifying an arbitrary 'localPath' for file operations. This grants the skill broad read/write access to the local filesystem. An attacker could potentially leverage this through prompt injection to an AI agent to exfiltrate sensitive local files (e.g., '/etc/passwd', '~/.ssh/id_rsa') or inject malicious files into critical system directories (e.g., '/usr/local/bin', '/Library/LaunchAgents'). The skill itself does not implement any path validation or sandboxing for these parameters. Implement robust path validation and sanitization within the 'dropbook' application to restrict 'localPath' to a designated sandbox directory or explicitly allowed user-controlled directories. Avoid allowing arbitrary absolute paths. For AI agent usage, the agent should also implement strict validation of 'localPath' before invoking these tools. | LLM | skill.json:78 | |
| 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/ryanlisse/dropbox/SKILL.md:1 |
