Deprecation warnings come from TypeScript compiler, ESLint, and npm audit. This Skill scans your codebase to detect all deprecation warnings from these sources, then prioritizes them by scope and risk so you know what to fix first.
Migration involves systematic code replacement with dual implementation testing and rollback strategies. This Skill provides step-by-step plans with code examples and test validation to ensure each deprecated pattern transitions safely to its modern equivalent.
Yes. This Skill scans dependency audits from npm and yarn, identifying breaking changes and deprecated APIs introduced during upgrades, then guides you through prioritized, safe replacements with impact analysis.
Breaking changes and deprecated APIs often surface during upgrades. This Skill assesses scope and risk, creates migration plans with safe replacement patterns, and validates changes through tests and regression checks.
Deprecation Handler analyzes impact and risk for each warning, helping you prioritize immediate fixes versus planned migrations based on scope and codebase dependencies.
Yes. The Skill handles TypeScript compiler warnings, ESLint linter warnings, and Node.js dependency deprecations, providing unified detection and migration guidance across your tech stack.
