typescript-expert

Quick Review

Exceptionally comprehensive TypeScript expert skill with deep coverage of type-level programming, performance optimization, migration strategies, and modern tooling. The description clearly signals proactive use and scope. The skill provides extensive task knowledge including diagnostic commands, code patterns, migration strategies, and decision matrices. Structure is logical with clear sections, though the single-file approach is dense (mitigated by good organization). Novelty is strong—handling complex type gymnastics, performance profiling, and monorepo management would consume significant tokens for a CLI agent. Minor areas for improvement: the skill could benefit from splitting some reference material into separate files, and the delegation logic to sub-experts could be slightly clearer about when to invoke vs. when to stop.
