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 Findings3
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| 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 | |
| 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 | |
| LOW | Custom Patching of Third-Party Library The skill includes a custom monkey-patching function (`monkeypatch_pydpf_method`) that modifies the internal behavior of the `pypdf` library. While intended to fix a specific bug, this practice introduces a fragile dependency on `pypdf`'s internal implementation. Future updates to `pypdf` could break this patch, leading to unexpected behavior, crashes, or potentially subtle data corruption, which could indirectly impact the security or reliability of PDF processing. Prefer using official `pypdf` releases that address the bug, or contribute the fix upstream. If a patch is absolutely necessary, isolate it and document its implications thoroughly. Consider using a fork or a more robust patching mechanism if the issue persists across versions. | Static | scripts/fill_fillable_fields.py:105 |
