SkillShield's automated analysis identified 4 findings: 0 critical, 0 high, 3 medium, and 1 low severity. Key findings include Sensitive environment variable access: $HOME, Network egress to untrusted endpoints, Covert behavior / concealment directives.
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 458b1186). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings4
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| MEDIUM | Sensitive environment variable access: $HOME Access to sensitive environment variable '$HOME' detected in shell context. Verify this environment variable access is necessary and the value is not exfiltrated. | Static | cli-tool/components/skills/development/playwright/SKILL.md:33 | |
| MEDIUM | Network egress to untrusted endpoints HTTP request to raw IP address Review all outbound network calls. Remove connections to webhook collectors, paste sites, and raw IP addresses. Legitimate API calls should use well-known service domains. | Manifest | cli-tool/components/mcps/devtools/figma-dev-mode.json:4 | |
| MEDIUM | Unpinned dependency for Playwright CLI The `scripts/playwright_cli.sh` script uses `npx --package @playwright/cli playwright-cli` and the `SKILL.md` recommends `npm install -g @playwright/cli@latest`. Both methods do not pin a specific version of the `@playwright/cli` package. This introduces a supply chain risk, as a new, potentially malicious, or breaking version of the package could be fetched and executed without explicit review. An attacker could publish a compromised version of `@playwright/cli` to the npm registry, which would then be automatically downloaded and run. Pin the `@playwright/cli` dependency to a specific, known-good version (e.g., `npx --package @playwright/cli@1.30.0 playwright-cli` or `npm install -g @playwright/cli@1.30.0`). Regularly review and update the pinned version to benefit from security patches and new features. | Static | scripts/playwright_cli.sh:13 | |
| LOW | Covert behavior / concealment directives Multiple zero-width characters (stealth text) Remove hidden instructions, zero-width characters, and bidirectional overrides. Skill instructions should be fully visible and transparent to users. | Manifest | cli-tool/components/mcps/devtools/jfrog.json:4 |
