Usage Guidance
Do not install this published artifact as-is. Ask the publisher to ship only inert fixture data or exclude tests from the release, restore or verify the test exclusion mechanism, and fix audit.sh path handling and allowlist scoping. If you must evaluate it, do so in a sandbox without credentials, sudo access, or outbound network access.
Capability Analysis
Type: OpenClaw Skill
Name: yoder-skill-auditor
Version: 3.1.0
This skill bundle is a security scanner designed to detect malicious patterns in other OpenClaw skills. It contains a comprehensive set of checks for credential harvesting, data exfiltration, obfuscation, prompt injection, privilege escalation, and more. The presence of malicious code patterns in the `tests/` directory is intentional, serving as test fixtures to validate the scanner's detection capabilities, and these are explicitly documented as such in `TEST-FIXTURES-WARNING.md` and excluded from the published package via `.clawignore`. The `audit.sh` script includes a `PATTERN_DEF_FILTER` to prevent self-flagging of its own detection logic. There is no evidence that the scanner itself performs any malicious actions, exfiltrates data, or attempts prompt injection against the agent running it. All functionalities are aligned with its stated purpose as a security auditing tool.
Capability Assessment
Credentials
Local file scanning is proportionate for an auditor, but runnable fixtures that read auth profiles or SSH keys, post to external URLs, download and execute code, or invoke sudo exceed what is needed for distributed scanner tests.
Install Mechanism
No install hook was found and skill.json lists only top-level scanner files, but the inspected artifact contains tests/ while CHANGELOG.md and TEST-FIXTURES-WARNING.md claim a .clawignore exclusion that is absent.
Instruction Scope
Normal commands are user-invoked and the test harness scans fixtures rather than executing them, but audit.sh handles attacker-controlled paths unsafely and can be bypassed or abused when scanning untrusted directories.
Persistence & Privilege
The normal tools do not create background persistence; trust_score.py writes trend history only when requested, but a shipped privilege-escalation fixture can copy into /usr/local/bin and set a setuid bit if manually run.
Purpose & Capability
The main purpose and required bins, bash and python3, fit a local skill security scanner, but the artifact also contains live credential-exfiltration, remote-code-execution, and privilege-escalation fixtures rather than inert test data.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install yoder-skill-auditor - After installation, invoke the skill by name or use
/yoder-skill-auditor - Provide required inputs per the skill's parameter spec and get structured output
