The body is mostly lean tables and commands with no padded concept explanations, but the inline severity-threshold table and File Type→Scan Type table duplicate content that already lives in the reference files, so it could be tightened.

It provides fully executable guidance — concrete git diff commands, exact MCP tool parameters (path, all_projects, severity_threshold), a copy-paste-ready report template with example rows, and a concrete .snyk policy YAML — matching the anchor for fully executable, copy-paste-ready instructions.

A clear five-phase sequence (Change Detection → Execute Scans → Filter → Report → Track Metrics) with numbered steps and genuine feedback loops in the error-handling table (timeout → retry with smaller scope; auth error → re-auth and retry; false positives → add policy → re-run to verify) satisfies the anchor for explicit validation and error-recovery loops.

Sections are well-organized, but the body never signals or links the two existing reference files, instead inlining a condensed severity table and file-type table that duplicate reference content — fitting the anchor for references present but not clearly signaled and content that should be separate being inline.

Lists multiple concrete actions across three named scan types — "Intelligently detects changes, runs appropriate scans (SAST, SCA, IaC), filters to only NEW issues, and prevents vulnerabilities at the source" — matching the anchor for listing multiple specific concrete actions.

It explicitly answers both what it does (proactive SAST/SCA/IaC scanning filtered to new issues) and when to use it via an explicit "Use this skill when:" bullet list, satisfying the anchor for clearly answering both what and when with explicit triggers.

The "Use this skill when" clause covers natural phrasings users would say — "scan for security issues", "check my changes", "security check", "proactive scan" — giving good coverage of common variations.

It carves a clear niche — proactive new-issue-only Snyk scanning at code-generation time with named MCP tools and distinctive triggers like "secure at inception" — making conflict with other skills unlikely.
