This is a comprehensive and highly actionable AI security audit skill with excellent workflow structure and concrete code examples for both vulnerable and remediated patterns. Its main weakness is verbosity — it explains some concepts Claude already knows and packs too much detail into a single file without progressive disclosure to supporting bundle files. The cross-references to related skills are a strength, but the skill itself would benefit from splitting detailed subsections (agent security, permission boundaries) into separate reference documents.
Suggestions
Trim the Background section to 1-2 sentences — Claude knows what prompt injection is; just state the three attack classes as a bullet list without elaboration.
Extract Steps 4 (Agent Security), 6 (Permission Boundaries), and the detailed defense assessment table into separate bundle files (e.g., AGENT_SECURITY.md, PERMISSION_AUDIT.md) and reference them from the main skill.
Remove or condense Step 5 (Prompt Leaking) — the common extraction attempts listed are widely known and add little value; a single sentence referencing the technique category would suffice.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is thorough but verbose in places. The Background section explains what prompt injection is, which Claude likely already knows. Some sections like Step 5 (prompt leaking) include basic extraction attempts that are common knowledge. However, the checklists and tables are efficient formats, and the methodology steps contain genuinely useful structural guidance. Overall, it could be tightened by ~30% without losing value. | 2 / 3 |
Actionability | The skill provides concrete, executable code examples for both vulnerable and remediated patterns across Python and JSX. Each step includes specific grep patterns, code snippets showing vulnerable vs. better approaches, and detailed checklists. The output format template is copy-paste ready with clear structure for findings. | 3 / 3 |
Workflow Clarity | The 7-step methodology is clearly sequenced from attack surface mapping through defense assessment. Each step builds logically on the previous one. The permission check checklist and defense assessment table serve as validation checkpoints. The prioritized remediation section in the output format provides a clear feedback mechanism for ranking and addressing findings. | 3 / 3 |
Progressive Disclosure | The skill is a monolithic document at ~300+ lines with no bundle files to offload detailed content. The cross-references to other skills (threat-modeling, owasp-audit, api-audit, ai-risk-management) are good, but the inline content is dense — the tool/agent audit section, permission boundaries section, and defense assessment could each be separate reference files. The references section at the end lists external resources but doesn't link to any bundled supporting materials. | 2 / 3 |
