The initial Spotify docs page shipped in #15130 was a setup guide. This
expands it into a full feature reference:
- Per-tool parameter table for all 9 tools, extracted from the real
schemas in tools/spotify_tool.py (actions, required/optional args,
premium gating).
- Free vs Premium feature matrix — which actions work on which tier,
so Free users don't assume Spotify tools are useless to them.
- Active-device prerequisite called out at the top; this is the #1
cause of '403 no active device' reports for every Spotify
integration.
- SSH / headless section explaining that browser auto-open is skipped
when SSH_CLIENT/SSH_TTY is set, and how to tunnel the callback port.
- Token lifecycle: refresh on 401, persistence across restarts, how
to revoke server-side via spotify.com/account/apps.
- Example prompt list so users know what to ask the agent.
- Troubleshooting expanded: no-active-device, Premium-required, 204
now_playing, INVALID_CLIENT, 429, 401 refresh-revoked, wizard not
opening browser.
- 'Where things live' table mapping auth.json / .env / Spotify app.
Verified with 'node scripts/prebuild.mjs && npx docusaurus build'
— page compiles, no new warnings.
