Layer Breakdown
Behavioral Risk Signals
Security Findings2
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| 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/pes0/exchange-2010-ews/SKILL.md:1 | |
| MEDIUM | Unpinned Dependency The skill documentation mentions `PyPDF2` as a prerequisite but does not specify a version. Similarly, the `__init__.py` file imports `exchangelib` without a pinned version. Unpinned dependencies can lead to unexpected behavior, breaking changes, or introduce vulnerabilities if a new version of the dependency contains malicious code or security flaws. It is best practice to pin dependencies to specific versions to ensure reproducibility and security. Pin the version of `PyPDF2` and `exchangelib` in the skill's requirements or documentation (e.g., `PyPDF2==x.y.z`, `exchangelib==a.b.c`). | LLM | SKILL.md:156 |
