- Remove unexpected id parameter from function_result in Claude and OpenAI Chat Interactions request translators to comply with Google Interactions API schema and fix HTTP 400 (Unknown parameter 'id' at 'input[N]').
- Remove redundant call_id parameter from function_call in Claude Interactions request translator to match schema requirements.
- Propagate is_error flag between Claude tool_result and Interactions function_result.
- Align Devin executor to prioritize call_id for function_result steps.
- Add regression tests covering parameter schemas and end-to-end executor request generation.
Closes: #5828
- Introduce `sanitizeGeminiInteractionsUnsupportedInputIDs` to remove `id` fields from Gemini interactions `input` and `content` items.
- Update execution logic to apply the sanitization process before upstreaming payloads.
- Add tests to ensure payloads are correctly sanitized and validate `call_id` pairing for Gemini interactions.
Closes: #5828
- Ensure Gemini, AI Studio, Vertex, and Antigravity requests end with a user turn to prevent upstream errors when trailing with model content.
- Preserve trailing turns that contain a function response and skip trailing adjustments for `countTokens` actions or Claude models.
- Introduce boundary normalization helpers to validate both leading and trailing turn roles.
Closes: #5358
Track when executor calls cross an upstream transport boundary and use that
signal to keep model/provider errors from being replaced by later local
preparation, selection, or internal failures.
Mark HTTP, websocket, relay, and usage-tracked transports as upstream
attempts, while avoiding marks for local validation, logging, missing
sessions, and successful websocket handshakes before request send.
Parse relative auth expiry metadata and adjust Antigravity refresh timing.
- Preserve API key entries with empty `api_key` when `base_url` is configured, and extend config dedupe/ID logic to include base URL, proxy, prefix, and headers so identities are stable.
- Update config/auth handling so `auth_kind=apikey` is treated as config API-key auth even without an `api_key` field, enabling base_url-only credential records.
- Ensure Gemini/Codex/XAI request path clears `Authorization`/provider auth headers when token is empty to avoid leaking unrelated auth state.
* fix(executor): prepend empty user turn for model-first requests targeting Gemini/Antigravity (#4959)
When forwarding sliced conversation histories or tool calls across OpenAI Responses,
OpenAI Chat Completions, Claude Messages, and native Gemini, native Gemini and Antigravity
Gemini endpoints require that conversation contents begin with a user turn.
Normalize leading turns at the executor boundary rather than the translator layer:
- Prepend an empty user turn ({"role":"user","parts":[{"text":""}]}) for Gemini, Gemini Vertex,
AI Studio, and Antigravity Gemini generation and CountTokens requests if the first turn is 'model'.
- Keep Antigravity Claude requests untouched to avoid adapter 400 errors.
- Ensure normalization runs after payload rules so payload index overrides target the original turns.
- Use no-copy GJSON inspection to keep overhead zero on valid user-first requests.
* fix(executor): inject Antigravity leading user after reasoning replay (#4959)
Replay can insert a model functionCall at contents[0] for sliced
tool-result history. Run the empty-user prepend on the final
requestPayload, after sanitize and prepareAntigravityGeminiReasoningReplayPayload.
- Introduced API handlers and executor logic for Google Interactions
- Added request and response transformations for OpenAI and Claude Interactions.
- Integrated Gemini API with Interactions support.
- Updated tests to validate Interactions request parsing and error handling.
- Refactored translator logic for Interactions data flows.
