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 Write via 'export_analysis' function.
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 14, 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 Write via 'export_analysis' function The `export_analysis` method in the `ScheduleDelayAnalyzer` class takes an `output_path` argument directly and uses it to write an Excel file (`pd.DataFrame(...).to_excel(output_path, ...)`) without any path validation or sanitization. This allows an attacker who can control the `output_path` argument to write files to arbitrary locations on the filesystem where the skill has write permissions. This could lead to overwriting critical system files, creating malicious files (e.g., web shells), or exfiltrating data to publicly accessible directories. Restrict the `output_path` to a safe, sandboxed directory (e.g., a temporary directory or a dedicated output directory for the skill). Implement strict path validation and sanitization to prevent directory traversal attacks (e.g., `../`). Do not allow writing to arbitrary absolute paths or paths outside the designated safe directory. | LLM | SKILL.md:150 | |
| 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/schedule-delay-analyzer/SKILL.md:1 |
