Trust Assessment
long-context 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 4 findings: 0 critical, 0 high, 3 medium, and 1 low severity. Key findings include Network egress to untrusted endpoints, Covert behavior / concealment directives, Unpinned Python Dependencies in Manifest.
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 | 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 Python Dependencies in Manifest The skill's manifest lists Python dependencies ('transformers', 'torch', 'flash-attn') without specifying exact versions. This practice can lead to supply chain vulnerabilities if a future version of any of these packages introduces breaking changes, security flaws, or malicious code. It also makes builds non-deterministic. Pin all Python dependencies to exact versions (e.g., `transformers==4.30.0`). Use a `requirements.txt` file with pinned versions or update the manifest to include version specifiers. | Static | SKILL.md:1 | |
| MEDIUM | Unpinned Git Repository Clone The skill instructs to clone a Git repository (`https://github.com/jquesnelle/yarn`) without specifying a particular commit hash or tag. This means the latest version of the `main` branch will be cloned. If the remote repository is compromised or its `main` branch is updated with malicious code, subsequent execution of scripts from this cloned repository (`python scripts/train.py`) could lead to arbitrary code execution. Specify a precise commit hash or tag when cloning external Git repositories (e.g., `git clone https://github.com/jquesnelle/yarn.git --branch v1.0.0` or `git clone https://github.com/jquesnelle/yarn.git && cd yarn && git checkout <commit_hash>`). | Static | SKILL.md:300 | |
| 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 |
