How to ask with this skill installed

Installing the skill gives your AI a method. Your request still has to provide the case-specific facts, constraints and expected output.

1Name the real task

Describe the decision or deliverable, not just the topic.

2Provide the evidence

Add source material, audience, limits and known facts.

3Define done

Set format, quality criteria and checks.

Adaptable starting prompt Replace the brackets with your case

When to use it

Use this skill when:

  • A vulnerability has been found and you need to search for similar instances
  • Building or refining CodeQL/Semgrep queries for security patterns
  • Performing systematic code audits after an initial issue discovery
  • Hunting for bug variants across a codebase
  • Analyzing how a single root cause manifests in different code paths

When not to use it

Do NOT use this skill for:

  • Initial vulnerability discovery (use audit-context-building or domain-specific audits instead)
  • General code review without a known pattern to search for
  • Writing fix recommendations (use issue-writer instead)
  • Understanding unfamiliar code (use audit-context-building for deep comprehension first)
