description	Enforce provider-capability architecture and provider manager usage
metadata	{"scope":"providers","priority":"medium"}

What this skill does

• Verifies provider capability boundaries.
• Ensures UI remains provider-agnostic.
• Checks provider manager orchestration correctness.
• Verifies external provider integrations (for example yt-dlp) are hidden behind typed service adapters.
• Verifies playback actions are routed through provider playback capabilities rather than direct UI-controlled process calls.
• Verifies playback seek actions are routed through provider playback capabilities rather than direct UI-controlled process calls.
• Verifies playback progress telemetry is routed through provider playback capabilities rather than direct UI-controlled process reads.
• Verifies provider playback uses reusable typed playback-service adapters for future provider scalability.
• Verifies visualizer source routing defaults to provider-scoped isolation and only uses global/system routing when explicitly configured.
• Verifies youtube provider owns a StreamUrlCache instance and all stream URL resolution flows through it (TTL 4h, max 3 concurrent fetches, evict-on-failure).
• Verifies prefetch is called with result track IDs after every search batch.

When to use

• Provider implementation changes
• Capability model changes
