Step-by-step workflow for adding a new DownloadClient impl (e.g., Aria2, NZBGet, putio). Walks the full integration: trait impl → wiremock tests → live_smoke env-gate → kind registration in rebuild_clients_cache → per-protocol mapping → settings UI form → CLAUDE.md quirks block. Use this when implementing a new client; following it end-to-end produces a complete, CI-clean PR.

Step-by-step workflow for adding a new Indexer impl beyond torznab/newznab (e.g., a private-tracker REST shape, a hypothetical anime-specific protocol). Walks the trait impl → caps fetcher → IndexerCache wiring → settings UI → CLAUDE.md notes. Skip this skill for adding a new torznab/newznab *deployment* (e.g., a new Prowlarr/Jackett indexer row) — that's just a Settings UI add. This skill is for adding a new *protocol*.
