About this skill
Security Scan
Resolve npm dependency vulnerabilities detected by Snyk.io security scans.
Activation Conditions
- User shares Snyk vulnerability reports
- Mentions CVEs/CWEs
- Asks to fix security issues in npm dependencies
Quick Reference
| Action | Rule |
|---|---|
| Fix direct deps | vuln-direct-deps.md |
| Fix transitive deps | vuln-transitive-deps.md |
Workflow
1. Assess
- Parse vulnerability report: package, version, CVE/CWE, severity, fixed version
- Categorize as direct (in package.json) or transitive (pulled in by another package)
2. Explore
- Check
package.jsonfor current versions and existing overrides - Check lockfile for actual resolved versions
- Search source code for direct usage of vulnerable package
- Check npm registry for available fixed versions:
npm view <package> versions --json
3. Fix
See rules for specific fix patterns.
4. Verify
bun i --yarn
bun run type:check
bun run lint
bun run build
bun run test
All must pass.
Tips
- Use exact versions for security fixes (no
^prefix) - Fix Critical/High severity first
- Replace unmaintained packages rather than patching
- Document workarounds with comments explaining why
Rules
See rules/ directory for detailed guidance.

Generate and edit images using Google's Nano Banana Pro (Gemini 3 Pro Image) API. Use when the user asks to generate, create, edit, modify, change, alter, or update images. Also use when user references an existing image file and asks to modify it in any way (e.g., "modify this image", "change the background", "replace X with Y"). Supports both text-to-image generation and image-to-image editing with configurable resolution (1K default, 2K, or 4K for high resolution). DO NOT read the image file first - use this skill directly with the --input-image parameter.
