From d41ff2076f95b3c2600a20dd0bcf54d75cf76202 Mon Sep 17 00:00:00 2001 From: Luis Pater Date: Tue, 23 Sep 2025 23:12:34 +0800 Subject: [PATCH] feat(translators): improve system instruction extraction and input handling for OpenAI and Claude responses - Enhanced support for extracting system instructions from input arrays. - Improved input message role and type determination logic for consistent message processing. - Refined instruction handling logic across translator types for better compatibility. --- internal/runtime/executor/claude_executor.go | 2 +- .../claude_openai-responses_request.go | 47 ++++++++++++++-- .../codex_openai-responses_request.go | 54 ++++++++++++++++--- .../gemini_openai-responses_request.go | 38 +++++++++++++ .../openai_openai-responses_request.go | 6 +++ 5 files changed, 134 insertions(+), 13 deletions(-) diff --git a/internal/runtime/executor/claude_executor.go b/internal/runtime/executor/claude_executor.go index 40a6f443..8d8c62c6 100644 --- a/internal/runtime/executor/claude_executor.go +++ b/internal/runtime/executor/claude_executor.go @@ -45,7 +45,7 @@ func (e *ClaudeExecutor) Execute(ctx context.Context, auth *cliproxyauth.Auth, r } from := opts.SourceFormat to := sdktranslator.FromString("claude") - body := sdktranslator.TranslateRequest(from, to, req.Model, bytes.Clone(req.Payload), false) + body := sdktranslator.TranslateRequest(from, to, req.Model, bytes.Clone(req.Payload), from != to) if !strings.HasPrefix(req.Model, "claude-3-5-haiku") { body, _ = sjson.SetRawBytes(body, "system", []byte(misc.ClaudeCodeInstructions)) diff --git a/internal/translator/claude/openai/responses/claude_openai-responses_request.go b/internal/translator/claude/openai/responses/claude_openai-responses_request.go index 4b6d828c..85fc59ce 100644 --- a/internal/translator/claude/openai/responses/claude_openai-responses_request.go +++ b/internal/translator/claude/openai/responses/claude_openai-responses_request.go @@ -68,16 +68,55 @@ func ConvertOpenAIResponsesRequestToClaude(modelName string, inputRawJSON []byte out, _ = sjson.Set(out, "stream", stream) // instructions -> as a leading message (use role user for Claude API compatibility) - if instr := root.Get("instructions");
