Trust Assessment
bitcoin-daily received a trust score of 26/100, placing it in the Untrusted category. This skill has significant security findings that require attention before use in production.
SkillShield's automated analysis identified 3 findings: 2 critical, 1 high, 0 medium, and 0 low severity. Key findings include Arbitrary command execution, Path Traversal in 'read' command allows arbitrary file access.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. The Manifest Analysis layer scored lowest at 40/100, indicating areas for improvement.
Last analyzed on February 14, 2026 (commit 13146e6a). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings3
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Arbitrary command execution Node.js child_process require 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/clawd21/bitcoin-daily/scripts/digest.js:61 | |
| CRITICAL | Arbitrary command execution Node.js synchronous shell execution 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/clawd21/bitcoin-daily/scripts/digest.js:62 | |
| HIGH | Path Traversal in 'read' command allows arbitrary file access The 'read' command in 'scripts/digest.js' constructs a file path using `path.join(ARCHIVE_DIR, dateStr, 'summary.md')`, where `dateStr` is taken directly from `process.argv[1]` without sanitization. An attacker can provide a `dateStr` containing path traversal sequences (e.g., `../../../../etc`) to read files outside the intended `ARCHIVE_DIR`, potentially leading to the exfiltration of sensitive system files or user data from the agent's environment. Sanitize the `dateStr` input to ensure it strictly adheres to the expected 'YYYY-MM-DD' format using a regular expression (e.g., `^\d{4}-\d{2}-\d{2}$`) before using it in `path.join`. This will prevent path traversal attacks. | LLM | scripts/digest.js:240 |
