google-sheet-api received a trust score of 76/100, placing it in the Mostly Trusted category. This skill has passed most security checks with only minor considerations noted.
SkillShield's automated analysis identified 3 findings: 0 critical, 1 high, 1 medium, and 1 low severity. Key findings include Unpinned npm dependency version, Node lockfile missing, Arbitrary file read via '@file' argument.
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 '@file' argument The `jsonFromArg` function allows reading arbitrary files from the filesystem if a command-line argument starts with `@`. An attacker controlling the arguments passed to this skill could specify a path like `@/etc/passwd` or `@/app/secrets.json` to read sensitive files. While the skill attempts to parse the content as JSON, the act of reading the file itself constitutes data exfiltration. If the file happens to contain valid JSON, its content could be processed and potentially sent to the Google Sheets API as part of a write or update operation. Implement strict validation for file paths passed via `@` arguments. Restrict file access to a designated, sandboxed directory, or disallow reading from arbitrary paths. Consider using an allow-list for file extensions or specific file names if file input is essential. Ensure that file content is not inadvertently logged or sent to external services if JSON parsing fails. | LLM | scripts/sheets-cli.js:144 | |
| MEDIUM | Unpinned npm dependency version Dependency 'googleapis' is not pinned to an exact version ('^140.0.0'). Pin dependencies to exact versions to reduce drift and supply-chain risk. | Dependencies | skills/codedao12/google-sheets-api/package.json | |
| LOW | Node lockfile missing package.json is present but no lockfile was found (package-lock.json, pnpm-lock.yaml, or yarn.lock). Commit a lockfile for deterministic dependency resolution. | Dependencies | skills/codedao12/google-sheets-api/package.json |
