BD skill-security-scanner
Security scanner for OpenClaw skills. Use when installing, updating, or auditing skills to detect malicious backdoors, suspicious code patterns, data exfiltration risks, and security vulnerabilities. Automatically analyzes Python/JavaScript/Shell code for dangerous functions (eval, exec, system calls), network requests, file operations, environment variable access, obfuscation patterns, and known attack signatures. Provides security score and installation recommendations.
Security scanner for OpenClaw skills.
As a process D 39/100 · Unfinished process — weak spots: result and completion, when it triggers, inputs and preconditions
How to improve
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Process rating: all ten parameters 39/100
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Failures and branches. Linear process with no failure handling
- 0Progress reporting. Says nothing while it works
- 20When it triggers. No condition that starts the skill
- 30Running it twice. 1 mutating operations with no state check
- 40Consistency. Frontmatter name (skill-security-scanner) differs from the folder (skill-security-scanner-clean)
- 60Tools and files. Uses tools (web) that frontmatter does not declare
- 100Steps. 40 steps
- 100Execution cost. Instruction body is 1556 tokens
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
Quality signals
- +5Description has no quoted example phrases that should trigger the skill
- +4Description does not say when NOT to use the skill (false activations)
- +3Output format is not stated: the model decides each time
- -215 emoji in the instructions: noise for the model
- -41 reference files, but SKILL.md never points to them: the model will not open them
- -31 of 2 scripts are never mentioned in SKILL.md
- +1No license
- +2Single-language instructions
- +3Description length 476: enough signal without eating the budget
- +4Structure: 18 headings
- +3Step-by-step instructions: 40 items
- +4Has examples (3 code blocks)
