SkillShield's automated analysis identified 2 findings: 0 critical, 1 high, 1 medium, and 0 low severity. Key findings include Missing required field: name, Arbitrary File Read via parse_file method.
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 | Arbitrary File Read via parse_file method The `parse_file` method in the `ConstructionJSONParser` class directly uses the `file_path` argument to open and read a file. If an untrusted user or a malicious prompt can control this `file_path` argument, they could specify paths to sensitive system files (e.g., `/etc/passwd`, environment configuration files, or other skill data) and exfiltrate their contents. This constitutes a Local File Inclusion (LFI) vulnerability, allowing data exfiltration. Implement strict validation and sanitization of the `file_path` argument. Restrict file access to a designated, sandboxed directory. Do not allow arbitrary paths. If the skill is intended to only process files uploaded by the user, ensure the `file_path` points to a secure, temporary location within the agent's sandbox, not an arbitrary system path. Consider using a file picker or a whitelist of allowed files/directories instead of direct path input. | LLM | SKILL.md:30 | |
| 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/datadrivenconstruction/json-parser/SKILL.md:1 |
