Verified each had no production caller (frontend, electron, or
internal backend) — only test references kept them looking alive
to coverage tools. Drops ~140 LOC of route handlers + helpers.
- POST /api/outputs/vibe-code: never wired up; frontend has no
vibe-code UI. Also drops VibeCodeRequest model and
VIBE_CODE_SYSTEM_PROMPT.
- GET /api/service/cost-breakdown: frontend Usage page reads
/usage-summary, which already returns by_model/by_provider.
- GET /api/service/status: zero callers; was placeholder.
- GET /api/service/spool/count: debug-only, no UI surface.
- GET /api/settings/default-system-prompt: frontend defines its
own DEFAULT_SYSTEM_PROMPT in settingsSlice.ts and never fetches
the backend constant.
- POST /api/browser/command: sole caller (browser_mcp_server.py
subprocess) was deleted in 8286cc1; browser_agent.py now calls
ws_manager.send_browser_command directly in-process.
Tests covering the removed endpoints are dropped along with the
now-unused mock-anthropic helpers in test_api_outputs.py.
