Trust Assessment
gtars received a trust score of 60/100, placing it in the Caution category. This skill has some security considerations that users should review before deployment.
SkillShield's automated analysis identified 4 findings: 0 critical, 2 high, 1 medium, and 1 low severity. Key findings include Network egress to untrusted endpoints, Covert behavior / concealment directives, Unpinned Python Dependency in Installation Instructions.
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 | |
|---|---|---|---|---|
| HIGH | Unpinned Python Dependency in Installation Instructions The skill's installation instructions for Python bindings use `uv uv pip install gtars` without specifying a version. This can lead to supply chain vulnerabilities where a malicious or buggy update to the `gtars` package could be automatically installed, compromising the user's environment or data. It's best practice to pin dependencies to a specific version or at least a major/minor version range. Pin the `gtars` package to a specific version or a version range in the installation command, e.g., `uv pip install gtars==0.1.0` or `uv pip install 'gtars>=0.1,<0.2'`. | Static | SKILL.md:26 | |
| HIGH | Unpinned CLI Dependency in Installation Instructions The skill's installation instructions for the command-line tools use `cargo install gtars-cli` without specifying a version. This can lead to supply chain vulnerabilities where a malicious or buggy update to the `gtars-cli` crate could be automatically installed, compromising the user's system. It's best practice to pin dependencies to a specific version. Pin the `gtars-cli` crate to a specific version in the installation command, e.g., `cargo install gtars-cli --version 0.1.0 --features "..."`. | Static | SKILL.md:32 | |
| 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 |
