AI Cleanup never succeeds with opencodeProvider

[cristeaadrian]

Summary

AI Cleanup (POST /api/user-profile/ai-cleanup) never succeeds with opencodeProvider/opencodeModel (no external memoryApiUrl). Every failure surfaces as Error: No AI provider configured for profile cleanup even though the provider is configured and working (auto-capture and profile learning use it fine), because callAICleanup catches any error from the opencode path and falls through to the unset memoryModel/memoryApiUrl branch.

Five stacked bugs, each hidden behind the next. Four are in callViaOpencodeWithClient (ai-cleanup.js), one is in the web UI (web/app.js):

1. noReply: true on the session.prompt call suppresses assistant generation, so no response is produced. The working auto-capture path avoids noReply for this reason. Set it to false.
2. Reads a nonexistent field. The prompt response is { info: AssistantMessage, parts: Array<Part> }, and AssistantMessage has no text field (per SDK types). Reading info.text yields undefined, then "AI response did not contain valid JSON". Read the text from promptResult.data.parts filtered by type === "text", as the rest of the codebase does.
3. Server timeout too short. The session.prompt race uses TIMEOUT_MS = 120000, but a real cleanup on a sizable profile takes longer, so it aborts. Raise it.
4. Client default timeout too short. fetchAPI in web/app.js defaults the /ai-cleanup fetch to 180000ms.
5. Explicit client timeout overrides the default. The cleanup call passes an explicit timeout: 180000, which wins over the fetchAPI default via options.timeout || .... This is the one that actually keeps hanging the modal: the browser aborts before the server responds, so the loading spinner never clears even though the server completed. Raise this explicit value too.

Repro

1. Configure opencodeProvider + opencodeModel, no external memory API.
2. Confirm auto-capture / profile learning work.
3. Web UI, click "AI Cleanup".
4. Fails or hangs; log chain: prompt timeout, then AI response did not contain valid JSON, then No AI provider configured.

Verified: with all five fixes applied, cleanup completes and the diff renders for review/apply.

Environment

• opencode-mem v2.19.4, OpenCode v1.18.3, macOS
• opencodeProvider: amazon-bedrock, opencodeModel: global.anthropic.claude-sonnet-5, no external memory API
