Lists three specific concrete vulnerability types: integer-as-boolean misuse, fake Jetton contracts, and forward TON without gas checks. Also specifies the domain (TON smart contracts) and the action (scans for vulnerabilities).

Clearly answers both 'what' (scans TON smart contracts for 3 specific vulnerabilities) and 'when' ('Use when auditing FunC contracts'), with an explicit trigger clause.

Includes good domain-specific terms like 'TON', 'smart contracts', 'FunC', 'Jetton', and 'auditing', but misses common user variations like 'security audit', 'vulnerability scan', 'Tact', '.fc files', 'contract security', or 'bug detection'. The trigger terms are somewhat narrow.

Highly distinctive — targets a very specific niche (TON/FunC smart contract vulnerability scanning) with named vulnerability types. Extremely unlikely to conflict with other skills.

The skill is extremely verbose at ~300+ lines. It includes unnecessary sections like 'When to Use This Skill' (6 bullet points of obvious contexts), 'Platform Detection' explaining file extensions and project structure Claude already knows, and extensive boilerplate. The description says 3 vulnerabilities but the content has duplicate/conflicting section numbering (two section 5s) and the pattern summary doesn't even match the title's claimed vulnerabilities (lists 'Missing Sender Check', 'Integer Overflow', 'Improper Gas Handling' instead of the described 'integer-as-boolean misuse, fake Jetton contracts, forward TON without gas checks'). Testing sections alone consume ~80 lines.

The skill provides concrete grep commands for detection and executable TypeScript test examples, plus FunC code for fixes. However, the vulnerability patterns themselves are inconsistent—the description promises 3 specific patterns but the inline summary lists different ones, and the actual detailed patterns are deferred to a VULNERABILITY_PATTERNS.md that doesn't exist in the bundle. The scanning workflow steps with checklists are useful but incomplete without the referenced resource.

The scanning workflow (Steps 1-5) provides a reasonable sequence with checklists for each step, and the grep commands give concrete detection methods. However, there are no explicit validation checkpoints or feedback loops—no 'if you find X, do Y before proceeding' logic. The duplicate section 5 numbering creates confusion about the document's own structure, and the workflow doesn't clearly specify what to do when findings are ambiguous.

The skill references 'resources/VULNERABILITY_PATTERNS.md' but no bundle files exist, making this a broken reference. The document is monolithic—the full finding template example (~50 lines), complete test suites (~60 lines), and the quick reference checklist could all be in separate files. The duplicate section numbering (two '## 5.' sections) indicates poor organization. Content that should be in referenced files is inlined, bloating the main skill.
