Set CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY=1 in render_overlay so the /model picker lists every gateway Messages-API endpoint, not just the ANTHROPIC_DEFAULT_* family aliases. Skipped under a Model Provider Service: its routing header would send a discovered gateway id to a provider that can't resolve it. Co-authored-by: Isaac

CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY=1inrender_overlayso Claude Code's/modelpicker lists every gateway Messages-API endpoint — not just theANTHROPIC_DEFAULT_*family aliases ucode injects today.Why
Claude Code has native gateway model discovery: when enabled, it fetches
GET {ANTHROPIC_BASE_URL}/v1/modelsand adds a picker row for each returned id (filtered to ids containingclaudeoranthropic). ucode already setsCLAUDE_CODE_USE_GATEWAY=1but never turned on discovery, so the picker only shows the family-alias rows. This flag makes custom Model Serving endpoints whose ids carryclaude/anthropic(e.g.main.default.my_anthropic_ms,system.ai.claude-opus-4-8) appear and route natively as 3-part FQNs.What changed
render_overlaysets the flag, gatednot provider: a Model Provider Service routes every request to the external provider via header, so a discovered gateway endpoint id would reach a provider that can't resolve it — discovery is off in that mode.gateway_proxy.py) forwards/v1/modelsto the gateway.Testing
test_agent_claude.py: flag is set on a normal launch; skipped underprovider.test_agent_claude.pysuite passes (102 tests).This pull request and its description were written by Isaac.
