Trust Assessment
clash-detection-analysis received a trust score of 66/100, placing it in the Caution category. This skill has some security considerations that users should review before deployment.
SkillShield's automated analysis identified 3 findings: 0 critical, 2 high, 1 medium, and 0 low severity. Key findings include Missing required field: name, Arbitrary File Read via User-Controlled Path, Arbitrary File Write via User-Controlled Path.
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 Findings3
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| HIGH | Arbitrary File Read via User-Controlled Path The skill's `ClashDetector` class initializes by opening an IFC file specified by `ifc_path`. If an attacker can control the `ifc_path` argument, they could potentially read any file accessible by the skill's execution environment, leading to information disclosure. Implement strict input validation for `ifc_path` to ensure it points only to allowed directories (e.g., a sandboxed temporary directory or a user-specific data directory). Avoid allowing arbitrary file system paths. | LLM | SKILL.md:66 | |
| HIGH | Arbitrary File Write via User-Controlled Path The skill provides functions `export_clash_report` and `generate_clash_html_report` that write output to `output_path`. If an attacker can control the `output_path` argument, they could write to arbitrary locations on the file system, potentially overwriting critical system files, writing malicious scripts, or consuming disk space, leading to data corruption or denial of service. Implement strict input validation for `output_path` to ensure it points only to allowed directories (e.g., a sandboxed temporary directory or a user-specific output directory). Avoid allowing arbitrary file system paths for writing. | LLM | SKILL.md:250 | |
| 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/clash-detection-analysis/SKILL.md:1 |
