+description: Diagnose Codex relay connectivity and compatibility without exposing credentials. Use when a user asks to test a custom API base URL, list available models, verify the Responses API or SSE streaming, investigate first-token latency, or check whether web search, image generation, and function calling are available through a relay.
+---
+
+# Diagnose Codex Relay
+
+Diagnose one layer at a time and report evidence instead of assuming a capability works.
+
+## Safety
+
+- Never print, quote, save, or commit an API key.
+- Redact authorization headers, query tokens, cookies, passwords, and signed URLs.
+- Prefer read-only health checks and minimal requests.
+- Ask before running sustained concurrency or bandwidth tests.
+- Do not modify Codex configuration unless the user explicitly asks for a change.
+
+## Workflow
+
+1. Identify the configured API base URL without displaying its secret.
+2. Check DNS resolution, TLS validity, and basic HTTP reachability.
+3. Request `/v1/models` and record status, elapsed time, and returned model IDs.
+4. Send a minimal synchronous request to the requested model.
+5. Test `/v1/responses` separately from Chat Completions.
+6. Test SSE streaming and measure time to the first meaningful event.
+7. Test function calling, web search, or image generation only when the user requests it.
+8. Separate client, reverse-proxy, relay, and upstream latency when diagnosing delays.
+9. Report results as passed, failed, unsupported, or not tested.
+
+## Evidence
+
+For each test, record:
+
+- Endpoint category, without secret query parameters.
+- HTTP status or transport error.
+- Total elapsed time and first-event latency where applicable.
+- Whether valid response content was received.
+- Whether the result proves the claimed capability.
+
+Do not claim web search succeeded without a returned search result or source. Do not claim image generation succeeded without a native image result or generated artifact.
+
+## Diagnosis Rules
+
+- `/v1/models` succeeding proves authentication and catalog access only.
+- A synchronous response does not prove SSE streaming works.
+- Chat Completions success does not prove the Responses API works.
+- A model name appearing in the catalog does not prove tool support.
+- Compare direct relay access with the public domain when isolating reverse-proxy delay.
+- When context length affects latency, compare short and long prompts separately.
+
+## Output
+
+Return a compact table of tests, followed by:
+
+- The most likely fault layer.
+- Tests that were not performed.
+- The smallest next action.
+- A reminder to rotate any credential accidentally exposed during testing.
