Trust Assessment
sports-ticker received a trust score of 24/100, placing it in the Untrusted category. This skill has significant security findings that require attention before use in production.
SkillShield's automated analysis identified 6 findings: 1 critical, 2 high, 2 medium, and 1 low severity. Key findings include Arbitrary command execution, Unsafe deserialization / dynamic eval, Suspicious import: urllib.request.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. The Manifest Analysis layer scored lowest at 63/100, 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 Findings6
| 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/robbyczgw-cla/sports-ticker/scripts/setup_crons.py:105 | |
| HIGH | Dangerous call: subprocess.run() Call to 'subprocess.run()' detected in function 'create_cron_via_openclaw'. This can execute arbitrary code. Avoid using dangerous functions like exec/eval/os.system. Use safer alternatives. | Static | skills/robbyczgw-cla/sports-ticker/scripts/setup_crons.py:105 | |
| HIGH | Command Injection via LLM-interpreted cron message The `scripts/auto_setup_crons.py` script generates cron job configurations for the agent. The `message` field within these configurations contains instructions for the LLM, including explicit shell commands like `Run `python3 scripts/live_monitor.py --event {event_id} --league {league} --sport {sport}``. The `{event_id}`, `{league}`, and `{sport}` values are interpolated directly from the ESPN API response, which is an untrusted external source. If an attacker can manipulate the ESPN API response (e.g., via a compromised ESPN API or a man-in-the-middle attack), or if the ESPN API itself returns malformed data containing shell metacharacters (e.g., `;`, `|`, `&`, `$(...)`), these characters could be injected into the shell command. If the LLM agent then executes this `message` string as a shell command, it would lead to arbitrary command execution on the host system. 1. **Sanitize Inputs**: Ensure all interpolated variables (`event_id`, `league`, `sport`, `match_desc`, etc.) are strictly validated and sanitized to remove any shell metacharacters before being included in the `message` string. 2. **Agent-side Execution**: The LLM agent should parse the `message` field and explicitly extract the command and its arguments, then execute them using a safe method (e.g., `subprocess.run` with `shell=False` and arguments passed as a list), rather than directly executing the entire string. 3. **Structured Commands**: Consider using a structured format for commands within the `message` field that the agent can parse safely, instead of embedding raw shell command strings. | LLM | scripts/auto_setup_crons.py:140 | |
| 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/robbyczgw-cla/sports-ticker/scripts/setup.py:5 | |
| 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/robbyczgw-cla/sports-ticker/scripts/espn.py:13 | |
| LOW | Node lockfile missing package.json is present but no lockfile was found (package-lock.json, pnpm-lock.yaml, or yarn.lock). Commit a lockfile for deterministic dependency resolution. | Dependencies | skills/robbyczgw-cla/sports-ticker/package.json |
