Trust Assessment
clickhousectl-local-dev received a trust score of 19/100, placing it in the Untrusted category. This skill has significant security findings that require attention before use in production.
SkillShield's automated analysis identified 4 findings: 2 critical, 1 high, 1 medium, and 0 low severity. Key findings include Arbitrary command execution, Remote code execution: curl/wget pipe to shell, Sensitive environment variable access: $HOME.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. The Static Code Analysis layer scored lowest at 63/100, indicating areas for improvement.
Last analyzed on May 1, 2026 (commit d2841614). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings4
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Arbitrary command execution Remote code download piped to interpreter 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/clickhousectl-local-dev/SKILL.md:28 | |
| CRITICAL | Remote code execution: curl/wget pipe to shell Detected a pattern that downloads and immediately executes remote code. This is a primary malware delivery vector. Never pipe curl/wget output directly to a shell interpreter. | Static | skills/clickhousectl-local-dev/SKILL.md:28 | |
| HIGH | Unverified remote script execution via curl | sh The skill instructs the user to download and execute a script directly from a remote URL (`https://clickhouse.com/cli`) using `curl | sh`. This method bypasses package managers and integrity checks (like checksums or cryptographic signatures), making the user vulnerable to supply chain attacks. If the remote server hosting the script or the script itself is compromised, an attacker could inject malicious code, leading to arbitrary command execution on the user's machine with the privileges of the executing user. Avoid direct execution of remote scripts without integrity verification. Recommend using a trusted package manager (if available for `clickhousectl`), or provide instructions for manual installation from a verified source. If `curl | sh` is unavoidable, include steps for the user to verify the script's checksum or cryptographic signature before execution. | LLM | SKILL.md:27 | |
| 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 | skills/clickhousectl-local-dev/SKILL.md:36 |
