output_item.added and that event never arrives, the completed response can still contain the call ID, name, and arguments. This guard reports stream_incomplete instead of delivering that call, so the chat client cannot execute the tool or continue the turn. The same premature failure occurs when output_item.done supplies the identity.

output_item.added accumulate without a total size limit. The 8 MiB scanner limit applies to each event, so many smaller deltas can retain a large buffer for one stream. This increases memory pressure, especially when several streams are active.

Walkthrough
feat(providers): translate chat completions onto Responses-only upstreams adds a
shared chat_via_responses* adapter that lets the ChatGPT Codex backend (which
serves only /v1/responses) implement /v1/chat/completions in both
non-streaming and SSE modes, then wires it into chatgpt.Provider. Documentation
in docs/providers/chatgpt.mdx and docs/providers/overview.mdx is updated to
describe the translation constraints and the chat↔responses surface.
Layout

max_completion_tokenshandling: resolved — explicit JSON
null skips the assignment, the field is then stripped from extras, and the
req.MaxTokensfallback fills inMaxOutputTokens(lines 74–84). - CodeRabbit —
ConvertMessagesToResponsesInputfor instruction-only requests:
resolved — line 90 returns[]core.ResponsesInputElement{}(non-nil empty
slice) when there is no input but a non-empty instruction string, so the
chatgptprovider'snormalizeInputcheck does not reject it.
Notes for the author (new)
internal/providers/chat_via_responses_input.go:240and:182—
documentation explicitly mentions strippingname; the inline comment on
line 181 ofchatToolMessageToResponsesItemis good. No action needed.- Docstring coverage on the new files sits below the 80% gate (CodeRabbit
pre-merge check) — most exported and many unexported helpers lack a
leading-line docstring.chatViaResponsesJSONString,responsesOutputReasoningText,
chatMessageReasoningText,responsesChatFinishReason,normalizeChatToolCallArguments,
terminalFinishReason,terminalOutputItem, thechat_*Viewdecode structs, and
the converter state struct are the highest-value targets; adding a one-line
comment per helper would clear the gate. - "Description check" warning (CodeRabbit) — the PR body still explains the
sandbox clone but does not summarize the implemented translation. A two-line
blurb linking tochat_via_responses.gois sufficient.
Verdict
The translation preserves the existing Chat Completions surface for the
ChatGPT subscription, including streaming, tool calls, reasoning replay,
refusals, usage chunks, and finish-reason mapping. The previously flagged
issues are addressed in c72ac355 and f9bd575b; go test ./internal/providers/
passes locally. Remaining items are stylistic (docstring coverage, PR
description) rather than blockers.

There was a problem hiding this comment.
NIT (minor) — handleItemDone falls back to itemsByIndex[outputIndex] when item.ID is unknown (lines 392–395), but then unconditionally calls emitItemExtraContent even if state == nil. A done event for an item the stream never announced (no delta, no output_item.added) will silently drop its extra_content. Either log + drop explicitly, or failTruncated if identity is required. Right now the replay state is best-effort.

There was a problem hiding this comment.
NIT (minor) — handleArgumentsDelta falls back to itemsByIndex[outputIndex] before registerItem, so a delta for an item that was only just announced via output_item.added (and registered by id) is fine; but state.toolIndex < 0 (line 457) silently returns. If a delta arrives for an item not announced as function_call, the upstream is misbehaving — a debug log would help correlate this with upstream bugs.

SUGGESTION (style) — chatMessageExtraFieldsForResponses strips five fields. Add a brief comment that mirrors chatToolMessageToResponsesItem above so the two paths agree visibly that name is intentionally excluded on both message and function_call_output items. Current comment covers the rationale but not the parallel-strip invariant.

There was a problem hiding this comment.
SUGGESTION (style) — the non-nil empty-slice return path for instruction-only requests is correct but is the only non-obvious behavior here. Add a one-line comment naming the chatgpt normalizeInput call site that depends on this so future refactors don't merge it back to nil.
| // The extra never travels upstream: an explicit null spells "not set" (the | ||
| // max_tokens fallback stays effective), and a non-integer value is a 400 | ||

There was a problem hiding this comment.
NIT (minor) — the Bailian max_completion_tokens null quirk is referenced in the comment but not exercised in tests. TestConvertChatRequestToResponses should include one case with explicit null and one with a numeric value to lock the precedence between max_completion_tokens and max_tokens.

PRAISE — clean use of ErrEventTooLarge for the buffer-cap overflow keeps the failure surface unified with the oversized-event path. pendingArgsBytes -= state.pendingArgs.Len() in deliverPendingIdentity balances the counter correctly on flush.

SUGGESTION (style) — chatPartsToResponsesBlocks covers text, input_text, output_text, image_url, input_image, input_audio, file, input_file.

Add a one-line comment justifying the silent skip (matching buildResponsesContentItemsFromParts).
