SkillShield's automated analysis identified 2 findings: 0 critical, 1 high, 0 medium, and 1 low severity. Key findings include Unpinned Python Dependencies, Email Password Exposed in Command-Line Arguments.
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 13, 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 | Email Password Exposed in Command-Line Arguments The `purelymail.py` script accepts the email password via a command-line option (`--password` or `-p`) for multiple commands (`config`, `test`, `send_test`, `inbox`). Passwords supplied as command-line arguments are visible in process listings (`ps aux`), shell history, and system logs, making them highly susceptible to unauthorized disclosure. Avoid passing sensitive credentials directly as command-line arguments. Instead, retrieve passwords from secure environment variables (e.g., `os.getenv`), a secure credential store, or use an interactive prompt with `getpass` for manual entry. The `SKILL.md` already suggests using environment variables in `clawdbot.json`, which is a more secure approach than command-line arguments. | LLM | scripts/purelymail.py:29 | |
| LOW | Unpinned Python Dependencies The `scripts/purelymail.py` script specifies `rich` and `typer` as dependencies without pinning them to specific versions. This can lead to supply chain risks, as future updates to these libraries might introduce breaking changes, unexpected behavior, or even malicious code without explicit review. Pin dependencies to exact versions (e.g., `rich==13.7.0`, `typer==0.9.0`) to ensure deterministic builds and prevent unexpected changes from upstream packages. | LLM | scripts/purelymail.py:4 |
