Linear Walkthrough
Generates a linear, narrative walkthrough of source material — code, documents, architecture diagrams, meeting notes, Jira tickets, or any combination. Produces a step-by-step guide that explains logic, purpose, and connections between components in a readable sequence.

Diagnosing Mac Performance
Use when the user reports their Mac is slow, sluggish, laggy, or unresponsive — or asks what's using CPU, memory, or battery. Also triggers on "check system performance", "what's eating my CPU", "Mac is hot", "fan is loud", or any request to diagnose macOS resource usage. Covers CPU hogs, memory pressure, swap thrashing, and runaway system daemons.

Workers Vitest Pool
Set up or upgrade vitest tests for Cloudflare Workers using @cloudflare/vitest-pool-workers.

Pins the modern stack (vitest 4 + pool-workers ≥0.15 + Node 22) and documents…
Interactive Explainer
Builds a self-contained interactive HTML visualisation that makes a process, algorithm, decision logic, or system visually and experientially understandable. Primary input is a linear walkthrough, but works directly from code, documents, or concept descriptions too — and can invoke the linear-walkthrough skill as an intermediate step if the source material lacks sufficient clarity or structure. U…
Finding Original Cds
Use when the user wants to find and add an original (non-remastered, non-deluxe, non-club-edition) CD pressing of an album to their Discogs wantlist, or decide which Discogs CD release to buy — e.g. "find an original US CD of X", "add the original pressing to my wantlist", "which CD pressing should I get", or avoiding remaster/deluxe/anniversary/club editions. Discogs-specific.
