Trust Assessment
docx-skill received a trust score of 58/100, 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: 1 critical, 0 high, 2 medium, and 0 low severity. Key findings include Missing required field: name, Unpinned npm dependency version, Arbitrary File Write via --output option.
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 12, 2026 (commit 13146e6a). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.

Behavioral Risk Signals
Security Findings3
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Arbitrary File Write via --output option The skill allows users to specify an arbitrary file path for the output DOCX file via the `--output` command-line option. The `fs.createWriteStream` function is used directly with this user-provided path without proper validation or sanitization. An attacker can exploit this to write a DOCX file to any location on the filesystem where the skill has write permissions. This could lead to denial of service (e.g., filling disk space, overwriting critical system files) or potentially remote code execution if a sensitive script or configuration file is overwritten and subsequently executed by another process. Implement strict validation and sanitization for the `--output` path. Options include: 1) Restricting output to a designated, sandboxed directory. 2) Using `path.basename()` if only a filename is expected, or `path.join()` with a secure base output directory to prevent directory traversal (e.g., `../`). 3) Ensuring the skill runs with the principle of least privilege, limiting its filesystem write permissions. | LLM | index.js: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/autogame-17/docx-skill/SKILL.md:1 | |
| MEDIUM | Unpinned npm dependency version Dependency 'commander' is not pinned to an exact version ('^12.0.0'). Pin dependencies to exact versions to reduce drift and supply-chain risk. | Dependencies | skills/autogame-17/docx-skill/package.json |
