Trust Assessment
kraken received a trust score of 10/100, placing it in the Untrusted category. This skill has significant security findings that require attention before use in production.
SkillShield's automated analysis identified 11 findings: 1 critical, 1 high, 8 medium, and 0 low severity. Key findings include Arbitrary command execution, Unsafe deserialization / dynamic eval, Missing required field: name.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. The Manifest Analysis layer scored lowest at 42/100, indicating areas for improvement.
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 Findings11
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Arbitrary command execution Python shell execution (os.system, subprocess) Review all shell execution calls. Ensure commands are static (not built from user input), use absolute paths, and are strictly necessary. Prefer library APIs over shell commands. | Manifest | skills/thesethrose/kraken/kraken_cli.py:412 | |
| HIGH | Dangerous call: subprocess.run() Call to 'subprocess.run()' detected in function 'run_api_passthrough'. This can execute arbitrary code. Avoid using dangerous functions like exec/eval/os.system. Use safer alternatives. | Static | skills/thesethrose/kraken/kraken_cli.py:412 | |
| MEDIUM | Unsafe deserialization / dynamic eval Decryption followed by code execution Remove obfuscated code execution patterns. Legitimate code does not need base64-encoded payloads executed via eval, encrypted-then-executed blobs, or dynamic attribute resolution to call system functions. | Manifest | skills/thesethrose/kraken/kraken_api.py:220 | |
| MEDIUM | Unsafe deserialization / dynamic eval Decryption followed by code execution Remove obfuscated code execution patterns. Legitimate code does not need base64-encoded payloads executed via eval, encrypted-then-executed blobs, or dynamic attribute resolution to call system functions. | Manifest | skills/thesethrose/kraken/kraken_api.py:243 | |
| MEDIUM | Unsafe deserialization / dynamic eval Decryption followed by code execution Remove obfuscated code execution patterns. Legitimate code does not need base64-encoded payloads executed via eval, encrypted-then-executed blobs, or dynamic attribute resolution to call system functions. | Manifest | skills/thesethrose/kraken/kraken_api.py:760 | |
| MEDIUM | Unsafe deserialization / dynamic eval Decryption followed by code execution Remove obfuscated code execution patterns. Legitimate code does not need base64-encoded payloads executed via eval, encrypted-then-executed blobs, or dynamic attribute resolution to call system functions. | Manifest | skills/thesethrose/kraken/kraken_api.py:762 | |
| MEDIUM | Missing required field: name The 'name' field is required for claude_code skills but is missing from frontmatter. Add a 'name' field to the SKILL.md frontmatter. | Static | skills/thesethrose/kraken/SKILL.md:1 | |
| MEDIUM | Suspicious import: urllib.request Import of 'urllib.request' detected. This module provides network or low-level system access. Verify this import is necessary. Network and system modules in skill code may indicate data exfiltration. | Static | skills/thesethrose/kraken/kraken_api.py:530 | |
| MEDIUM | Unpinned Python dependency version Requirement 'python-kraken-sdk>=1.2.0' is not pinned to an exact version. Pin Python dependencies with '==<exact version>'. | Dependencies | skills/thesethrose/kraken/requirements.txt:1 | |
| MEDIUM | Unpinned Python dependency version Requirement 'python-dotenv>=1.0.0' is not pinned to an exact version. Pin Python dependencies with '==<exact version>'. | Dependencies | skills/thesethrose/kraken/requirements.txt:2 | |
| INFO | Unpinned or Loosely Pinned Dependencies The `requirements.txt` file uses loose version pinning (`>=`) for `python-kraken-sdk` and `python-dotenv`. While this allows for automatic updates, it introduces a minor supply chain risk as future major versions could introduce breaking changes or vulnerabilities without explicit review. Strict pinning (`==`) is recommended for production environments to ensure reproducibility and prevent unexpected behavior from dependency updates. Pin dependencies to exact versions (e.g., `python-kraken-sdk==1.2.0`) to ensure build reproducibility and prevent unexpected behavior from future dependency updates. Regularly review and manually update dependencies to incorporate security patches. | LLM | requirements.txt:1 |
