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

ActionRule
Fix direct depsvuln-direct-deps.md
Fix transitive depsvuln-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.json for 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.

nano-banana-pro

garg-aayush

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.

pdf-to-markdown

aliceisjustplaying

Convert entire PDF documents to clean, structured Markdown for full context loading. Use this skill when the user wants to extract ALL text from a PDF into context (not grep/search), when discussing or analyzing PDF content in full, when the user mentions "load the whole PDF", "bring the PDF into context", "read the entire PDF", or when partial extraction/grepping would miss important context. This is the preferred method for PDF text extraction over page-by-page or grep approaches.
