ucode not detecting coding agents

[jason-cairns]

Running ucode configure; auth works, correct workspace selected. Receiving:

• A browser may open for `databricks auth login`.
Profile DEFAULT was successfully saved
✔ Databricks authentication complete
✔ Unity AI Gateway detected
ERROR No coding agents are available on this workspace.

This is not possible, as I'm using the coding agents on the workspace already, using direct config from databricks.

Could you provide output from these commands

  TOKEN=$(databricks auth token --host <workspace> --output json | jq -r .access_token)
  HOST=<workspace-hostname>

  # What Unity AI Gateway detection sees
  curl -sS -o /dev/null -w "messages HEAD: %{http_code}\n" -I -H "Authorization: Bearer $TOKEN" \
    "https://$HOST/ai-gateway/anthropic/v1/messages"

  # What claude discovery sees
  curl -sS -H "Authorization: Bearer $TOKEN" \
    "https://$HOST/ai-gateway/anthropic/v1/models" | jq .

  # What codex/gemini discovery sees
  curl -sS -H "Authorization: Bearer $TOKEN" \
    "https://$HOST/api/2.0/serving-endpoints:foundation-models" \
    | jq '.endpoints[] | {name, v2: [.config.served_entities[].foundation_model.ai_gateway_v2_supported], api_types: [.config.served_entities[].foundation_model.api_types[]?]}'

Thank you for responding. The command output is given as:

> curl -sS -o /dev/null -w "messages HEAD: %{http_code}\n" -I -H "Authorization: Bearer $TOKEN" \
                                               "https://$HOST/ai-gateway/anthropic/v1/messages"

Worth noting that the manual set up generated in the Integrate External Agents popup on Databricks works for Claude, with:

{
    "env": {
        "ANTHROPIC_MODEL": "databricks-claude-opus-4-7",
        "ANTHROPIC_BASE_URL": "https://<REDACTED>.azuredatabricks.net/serving-endpoints/anthropic",
        "ANTHROPIC_AUTH_TOKEN": "<your_token_will_appear_here>",
        "ANTHROPIC_DEFAULT_OPUS_MODEL": "databricks-claude-opus-4-7",
        "ANTHROPIC_DEFAULT_SONNET_MODEL": "databricks-claude-sonnet-4-6",
        "ANTHROPIC_DEFAULT_HAIKU_MODEL": "databricks-claude-haiku-4-5",
        "ANTHROPIC_CUSTOM_HEADERS": "x-databricks-use-coding-agent-mode: true",
        "CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS": "1"
    }
}

Also, in the Unity AI Gateway page, the LLMs tab is greyed out, with the mouseover reading:

Enable AI Gateway v2 to access LLM endpoints in Unity AI Gateway.

Looking through the Previews window, I don't see anything relating to enabling AI Gateway v2.
