product-ai-public

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.

Apply the product management philosophy to PRDs, OKRs, strategy docs, roadmaps, product decisions, prioritization, and feature evaluation. Problem-first thinking, outcomes over outputs, empowered teams.

Set up or upgrade vitest tests for Cloudflare Workers using @cloudflare/vitest-pool-workers. Use when scaffolding tests in a new Worker, when an existing Worker is on pool-workers <0.13 (vitest 2/3) and needs to upgrade, or when the test suite hits "Isolated storage failed" / "Expected .sqlite, got .sqlite-shm" errors. Pins the modern stack (vitest 4 + pool-workers ≥0.15 + Node 22) and documents the v2→v4 migration recipe.

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. Use when the user wants to "see how this works", wants an interactive version of a walkthrough, wants to explain a process visually to an audience, or asks to "visualise", "animate", or "build an interactive explanation" of anything. Richer and more interactive is always preferred, as long as it makes the logic clearer rather than decorating it.

Safety checks for editing system files — commands in .opencode/command/, skills in .opencode/skills/, agents in .opencode/agent/, or AGENTS.md itself. Load when creating or modifying any of these files.

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.

Discord bot development on Cloudflare Workers — Discord API, Developer Portal, slash commands, Gateway WebSocket, Interactions Endpoint, bot permissions, intents, and Ed25519 verification.

Use when the user says "check this skill", "review this skill", "quality check skill", "audit this skill", "skill quality check", "does this skill follow best practices", or provides a path to a SKILL.md file for review. Also triggers on "check skill quality", "skill review", or "is this skill well-written". Audits a skill file against the AIDB Skills Masterclass best practices framework, checking for the 5 skill killers, proper anatomy, scoping, and context binding.

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. Use when the user wants to understand how something works, wants to explain a system to others, asks to "walk through" or "explain" code or docs, or needs to document a system's logic for learning or onboarding. Also trigger when the user provides files or code and asks "how does this work?" or "take me through this."
