From 3a9ac7ef331da59da78d8504cab00a639f837cb7 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ernesto=20Mart=C3=ADnez?= Date: Thu, 27 Nov 2025 20:14:30 +0100 Subject: [PATCH 01/68] feat(auth): add GitHub Copilot authentication and API integration Add complete GitHub Copilot support including: - Device flow OAuth authentication via GitHub's official client ID - Token management with automatic caching (25 min TTL) - OpenAI-compatible API executor for api.githubcopilot.com - 16 model definitions (GPT-5 variants, Claude variants, Gemini, Grok, Raptor) - CLI login command via -github-copilot-login flag - SDK authenticator and refresh registry integration Enables users to authenticate with their GitHub Copilot subscription and use it as a backend provider alongside existing providers. ---

Fix conversationState field order (chatTriggerType must be first) - Add conditional profileArn inclusion based on auth method - builder-id auth (AWS SSO) doesn't require profileArn - social auth (Google OAuth) requires profileArn ### Stream Processing Enhancements - Add headersLen boundary validation to prevent slice out of bounds - Handle incomplete tool use at EOF by flushing pending data - Separate message_delta and message_stop events for proper streaming - Add error logging for JSON unmarshal failures ### JSON Repair Improvements - Add escapeNewlinesInStrings() to handle control characters in JSON strings - Remove incorrect unquotedKeyPattern that broke valid JSON content - Fix handling of streaming fragments with embedded newlines/tabs ### Debug Info Filtering (Optional) - Add filterHeliosDebugInfo() to remove [HELIOS_CHK] blocks - Pattern matches internal state tracking from Kiro/Amazon Q - Currently disabled pending further testing ### Usage Tracking - Add usage information extraction in message_delta response - Include prompt_tokens, completion_tokens, total_tokens in OpenAI format --- ## 中文描述 ### 请求格式修复 - 修复 conversationState 字段顺序（chatTriggerType 必须在第一位） - 根据认证方式条件性包含 profileArn - builder-id 认证（AWS SSO）不需要 profileArn - social 认证（Google OAuth）需要 profileArn ### 流处理增强 - 添加 headersLen 边界验证，防止切片越界 - 在 EOF 时处理未完成的工具调用，刷新待处理数据 - 分离 message_delta 和 message_stop 事件以实现正确的流式传输 - 添加 JSON 反序列化失败的错误日志 ### JSON 修复改进 - 添加 escapeNewlinesInStrings() 处理 JSON 字符串中的控制字符 - 移除错误的 unquotedKeyPattern，该模式会破坏有效的 JSON 内容 - 修复包含嵌入换行符/制表符的流式片段处理 ### 调试信息过滤（可选） - 添加 filterHeliosDebugInfo() 移除 [HELIOS_CHK] 块 - 模式匹配来自 Kiro/Amazon Q 的内部状态跟踪信息 - 目前已禁用，等待进一步测试 ### 使用量跟踪 - 在 message_delta 响应中添加 usage 信息提取 - 以 OpenAI 格式包含 prompt_tokens、completion_tokens、total_tokens --- internal/runtime/executor/kiro_executor.go | 277 ++++++++++++++++-- .../chat-completions/kiro_openai_response.go | 15 +- 2 files changed, 260 insertions(+), 32 deletions(-) diff --git a/internal/runtime/executor/kiro_executor.go b/internal/runtime/executor/kiro_executor.go index b69fd8be..534e0c58 100644 --- a/internal/runtime/executor/kiro_executor.go +++ b/internal/runtime/executor/kiro_executor.go @@ -121,7 +121,12 @@ func (e *KiroExecutor) Execute(ctx context.Context, auth *cliproxyauth.Auth, req return resp, fmt.Errorf("kiro: access token not found in auth") } if profileArn == "" { -

Output Token Calculation Improvement (lines 317-330) - Replace simple len(content)/4 estimation with tiktoken-based calculation - Add fallback to character count estimation if tiktoken fails - Improves token counting accuracy for usage tracking ### 2. Stream Handler Panic Recovery (lines 528-533) - Add defer/recover block in streamToChannel goroutine - Prevents single request crashes from affecting the entire service ### 3. Struct Field Reordering (lines 670-673) - Reorder kiroToolResult struct fields: Content, Status, ToolUseID - Ensures consistency with API expectations ### 4. Message Merging Function (lines 778-780, 2356-2483) - Add mergeAdjacentMessages() to combine consecutive messages with same role - Add helper functions: mergeMessageContent(), blockToMap(), createMergedMessage() - Required by Kiro API which doesn't allow adjacent messages from same role ### 5. Empty Content Handling (lines 791-800) - Add default content for empty history messages - User messages with tool results: "Tool results provided." - User messages without tool results: "Continue" ### 6. Assistant Last Message Handling (lines 811-830) - Detect when last message is from assistant - Create synthetic "Continue" user message to satisfy Kiro API requirements - Kiro API requires currentMessage to be userInputMessage type ### 7. Duplicate Content Event Detection (lines 1650-1660) - Track lastContentEvent to detect duplicate streaming events - Skip redundant events to prevent duplicate content in responses - Based on AIClient-2-API implementation for Kiro ### 8. Streaming Token Calculation Enhancement (lines 1785-1817) - Add accumulatedContent buffer for streaming token calculation - Use tiktoken for accurate output token counting during streaming - Add fallback to character count estimation with proper logging ### 9. JSON Repair Enhancement (lines 2665-2818) - Implement conservative JSON repair strategy - First try to parse JSON directly - if valid, return unchanged - Add bracket balancing detection and repair - Only repair when necessary to avoid corrupting valid JSON - Validate repaired JSON before returning ### 10. HELIOS_CHK Filtering Removal (lines 2500-2504, 3004-3039) - Remove filterHeliosDebugInfo function - Remove heliosDebugPattern regex - HELIOS_CHK fields now handled by client-side processing ### 11.

**Thinking Support**: - Enabled thinking support for all Kiro Claude models, including Haiku 4.5 and agentic variants. - Updated `model_definitions.go` with thinking configuration (Min: 1024, Max: 32000, ZeroAllowed: true). - Fixed `extended_thinking` field names in `model_registry.go` (from `min_budget`/`max_budget` to `min`/`max`) to comply with Claude API specs, enabling thinking control in clients like Claude Code. - **Kiro Executor Fixes**: - Fixed `budget_tokens` handling: explicitly disable thinking when budget is 0 or negative. - Removed aggressive duplicate content filtering logic that caused truncation/data loss. - Enhanced thinking tag parsing with `extractThinkingFromContent` to correctly handle interleaved thinking/text blocks. - Added EOF handling to flush pending thinking tag characters, preventing data loss at stream end. - **Performance**: - Optimized Claude stream handler (v6.2) with reduced buffer size (4KB) and faster flush interval (50ms) to minimize latency and prevent timeouts. --- internal/registry/model_definitions.go | 8 + internal/registry/model_registry.go | 16 +- internal/runtime/executor/kiro_executor.go | 197 +++++++++++++++++++-- sdk/api/handlers/claude/code_handlers.go | 26 +-- 4 files changed, 219 insertions(+), 28 deletions(-) diff --git a/internal/registry/model_definitions.go b/internal/registry/model_definitions.go index 4df0cf67..c6282759 100644 --- a/internal/registry/model_definitions.go +++ b/internal/registry/model_definitions.go @@ -895,6 +895,7 @@ func GetKiroModels() []*ModelInfo { Description: "Claude Opus 4.5 via Kiro (2.2x credit)", ContextLength: 200000, MaxCompletionTokens: 64000, + Thinking: &ThinkingSupport{Min: 1024, Max: 32000, ZeroAllowed: true, DynamicAllowed: true}, }, { ID: "kiro-claude-sonnet-4-5", @@ -906,6 +907,7 @@ func GetKiroModels() []*ModelInfo { Description: "Claude Sonnet 4.5 via Kiro (1.3x credit)", ContextLength: 200000, MaxCompletionTokens: 64000, + Thinking: &ThinkingSupport{Min: 1024, Max: 32000, ZeroAllowed: true, DynamicAllowed: true}, }, { ID: "kiro-claude-sonnet-4", @@ -917,6 +919,7 @@ func GetKiroModels() []*ModelInfo { Description: "Claude Sonnet 4 via Kiro (1.3x credit)", ContextLength: 200000, MaxCompletionTokens: 64000, + Thinking: &ThinkingSupport{Min: 1024, Max: 32000, ZeroAllowed: true, DynamicAllowed: true}, }, { ID: "kiro-claude-haiku-4-5", @@ -928,6 +931,7 @@ func GetKiroModels() []*ModelInfo { Description: "Claude Haiku 4.5 via Kiro (0.4x credit)", ContextLength: 200000, MaxCompletionTokens: 64000, + Thinking: &ThinkingSupport{Min: 1024, Max: 32000, ZeroAllowed: true, DynamicAllowed: true}, }, // --- Agentic Variants (Optimized for coding agents with chunked writes) --- { @@ -940,6 +944,7 @@ func GetKiroModels() []*ModelInfo { Description: "Claude Opus 4.5 optimized for coding agents (chunked writes)", ContextLength: 200000, MaxCompletionTokens: 64000, + Thinking: &ThinkingSupport{Min: 1024, Max: 32000, ZeroAllowed: true, DynamicAllowed: true}, }, { ID: "kiro-claude-sonnet-4-5-agentic", @@ -951,6 +956,7 @@ func GetKiroModels() []*ModelInfo { Description: "Claude Sonnet 4.5 optimized for coding agents (chunked writes)", ContextLength: 200000, MaxCompletionTokens: 64000, + Thinking: &ThinkingSupport{Min: 1024, Max: 32000, ZeroAllowed: true, DynamicAllowed: true}, }, { ID: "kiro-claude-sonnet-4-agentic", @@ -962,6 +968,7 @@ func GetKiroModels() []*ModelInfo { Description: "Claude Sonnet 4 optimized for coding agents (chunked writes)", ContextLength: 200000, MaxCompletionTokens: 64000, + Thinking: &ThinkingSupport{Min: 1024, Max: 32000, ZeroAllowed: true, DynamicAllowed: true}, }, { ID: "kiro-claude-haiku-4-5-agentic", @@ -973,6 +980,7 @@ func GetKiroModels() []*ModelInfo { Description: "Claude Haiku 4.5 optimized for coding agents (chunked writes)", ContextLength: 200000, MaxCompletionTokens: 64000, + Thinking: &ThinkingSupport{Min: 1024, Max: 32000, ZeroAllowed: true, DynamicAllowed: true}, }, } } diff --git a/internal/registry/model_registry.go b/internal/registry/model_registry.go index f3517bde..8f575df4 100644 --- a/internal/registry/model_registry.go +++ b/internal/registry/model_registry.go @@ -748,7 +748,8 @@ func (r *ModelRegistry) convertModelToMap(model *ModelInfo, handlerType string) } return result -

为 AMP 代理、SOCKS5 代理和 HTTP 代理配置优化的连接池参数 - MaxIdleConnsPerHost 从默认的 2 增加到 20，支持更多并发用户 - MaxConnsPerHost 设为 0（无限制），避免连接瓶颈 - 添加 IdleConnTimeout (90s) 和其他超时配置 ### Kiro 执行器增强 - 添加 Event Stream 消息解析的边界保护，防止越界访问 - 实现实时使用量估算（每 5000 字符或 15 秒发送 ping 事件） - 正确从上游事件中提取并传递 stop_reason - 改进输入 token 计算，优先使用 Claude 格式解析 - 添加 max_tokens 截断警告日志 ### Token 计算改进 - 添加 tokenizer 缓存（sync.Map）避免重复创建 - 为 Claude/Kiro/AmazonQ 模型添加 1.1 调整因子 - 新增 countClaudeChatTokens 函数支持 Claude API 格式 - 支持图像 token 估算（基于尺寸计算） ### 认证刷新优化 - RefreshLead 从 30 分钟改为 5 分钟，与 Antigravity 保持一致 - 修复 NextRefreshAfter 设置，防止频繁刷新检查 - refreshFailureBackoff 从 5 分钟改为 1 分钟，加快失败恢复 --- ## English Description ### Connection Pool Optimization - Configure optimized connection pool parameters for AMP proxy, SOCKS5 proxy, and HTTP proxy - Increase MaxIdleConnsPerHost from default 2 to 20 to support more concurrent users - Set MaxConnsPerHost to 0 (unlimited) to avoid connection bottlenecks - Add IdleConnTimeout (90s) and other timeout configurations ### Kiro Executor Enhancements - Add boundary protection for Event Stream message parsing to prevent out-of-bounds access - Implement real-time usage estimation (send ping events every 5000 chars or 15 seconds) - Correctly extract and pass stop_reason from upstream events - Improve input token calculation, prioritize Claude format parsing - Add max_tokens truncation warning logs ### Token Calculation Improvements - Add tokenizer cache (sync.Map) to avoid repeated creation - Add 1.1 adjustment factor for Claude/Kiro/AmazonQ models - Add countClaudeChatTokens function to support Claude API format - Support image token estimation (calculated based on dimensions) ### Authentication Refresh Optimization - Change RefreshLead from 30 minutes to 5 minutes, consistent with Antigravity - Fix NextRefreshAfter setting to prevent frequent refresh checks - Change refreshFailureBackoff from 5 minutes to 1 minute for faster failure recovery --- internal/api/modules/amp/proxy.go | 50 +- internal/runtime/executor/kiro_executor.go | 610 ++++++++++++++++----- internal/runtime/executor/proxy_helpers.go | 16 +- internal/runtime/executor/token_helpers.go | 287 +++++++++- internal/util/proxy.go | 17 +- sdk/auth/kiro.go | 18 +- sdk/cliproxy/auth/manager.go | 6 +- 7 files changed, 840 insertions(+), 164 deletions(-) diff --git a/internal/api/modules/amp/proxy.go b/internal/api/modules/amp/proxy.go index 6a6b1b54..5a3f2081 100644 --- a/internal/api/modules/amp/proxy.go +++ b/internal/api/modules/amp/proxy.go @@ -7,11 +7,13 @@ import ( "errors" "fmt" "io" + "net" "net/http" "net/http/httputil" "net/url" "strconv" "strings" + "time" "github.com/gin-gonic/gin" log "github.com/sirupsen/logrus" @@ -36,6 +38,22 @@ func createReverseProxy(upstreamURL string, secretSource SecretSource) (*httputi } proxy := httputil.NewSingleHostReverseProxy(parsed) + + // Configure custom Transport with optimized connection pooling for high concurrency + proxy.Transport = &http.Transport{ + MaxIdleConns: 100, + MaxIdleConnsPerHost: 20, // Increased from default 2 to support more concurrent users + MaxConnsPerHost: 0, // No limit on max concurrent connections per host + IdleConnTimeout: 90 * time.Second, + DialContext: (&net.Dialer{ + Timeout: 30 * time.Second, + KeepAlive: 30 * time.Second, + }).DialContext, + TLSHandshakeTimeout: 10 * time.Second, + ResponseHeaderTimeout: 60 * time.Second, + ExpectContinueTimeout: 1 * time.Second, + } + originalDirector := proxy.Director // Modify outgoing requests to inject API key and fix routing @@ -64,7 +82,15 @@ func createReverseProxy(upstreamURL string, secretSource SecretSource) (*httputi // Modify incoming responses to handle gzip without Content-Encoding // This addresses the same issue as inline handler gzip handling, but at the proxy level proxy.ModifyResponse = func(resp *http.Response) error { -

Content-Transfer-Encoding: 8bit 为Kiro供应商添加WEB UI OAuth登录入口和认证文件过滤器 ## Changes / 更改内容 ### Frontend / 前端 (management.html) - Add Kiro OAuth card UI with support for AWS Builder ID, Google, and GitHub login methods - 添加Kiro OAuth卡片UI，支持AWS Builder ID、Google和GitHub三种登录方式 - Add i18n translations for Kiro OAuth (Chinese and English) - 添加Kiro OAuth的中英文国际化翻译 - Add Kiro filter button in auth files management page - 在认证文件管理页面添加Kiro过滤按钮 - Implement JavaScript methods: startKiroOAuth(), openKiroLink(), copyKiroLink(), copyKiroDeviceCode(), startKiroOAuthPolling(), resetKiroOAuthUI() - 实现JavaScript方法：startKiroOAuth()、openKiroLink()、copyKiroLink()、copyKiroDeviceCode()、startKiroOAuthPolling()、resetKiroOAuthUI() ### Backend / 后端 - Add /kiro-auth-url endpoint for Kiro OAuth authentication (auth_files.go) - 添加/kiro-auth-url端点用于Kiro OAuth认证 (auth_files.go) - Fix GetAuthStatus() to correctly parse device_code and auth_url status - 修复GetAuthStatus()以正确解析device_code和auth_url状态 - Change status delimiter from ':' to '|' to avoid URL parsing issues - 将状态分隔符从':'改为'|'以避免URL解析问题 - Export CreateToken method in social_auth.go - 在social_auth.go中导出CreateToken方法 - Register Kiro OAuth routes in server.go - 在server.go中注册Kiro OAuth路由 ## Files Modified / 修改的文件 - management.html - internal/api/handlers/management/auth_files.go -

From: Ravens2121 Date: Sun, 14 Dec 2025 11:54:57 +0800 Subject: [PATCH 36/68] feat(kiro): enhance request translation and fix streaming issues MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit English: - Fix tag parsing: only parse at response start, avoid misinterpreting discussion text - Add token counting support using tiktoken for local estimation - Support top_p parameter in inference config - Handle max_tokens=-1 as maximum (32000 tokens) - Add tool_choice and response_format parameter handling via system prompt hints - Support multiple thinking mode detection formats (Claude API, OpenAI reasoning_effort, AMP/Cursor) - Shorten MCP tool names exceeding 64 characters - Fix duplicate [DONE] marker in OpenAI SSE streaming - Enhance token usage statistics with multiple event format support - Add code fence markers to constants 中文: - 修复 标签解析：仅在响应开头解析，避免误解析讨论文本中的标签 - 使用 tiktoken 实现本地 token 计数功能 - 支持 top_p 推理配置参数 - 处理 max_tokens=-1 转换为最大值（32000 tokens） - 通过系统提示词注入实现 tool_choice 和 response_format 参数支持 - 支持多种思考模式检测格式（Claude API、OpenAI reasoning_effort、AMP/Cursor） - 截断超过64字符的 MCP 工具名称 - 修复 OpenAI SSE 流中重复的 [DONE] 标记 - 增强 token 使用量统计，支持多种事件格式 - 添加代码围栏标记常量 --- internal/runtime/executor/kiro_executor.go | 855 +++++++++++++++++- .../kiro/claude/kiro_claude_request.go | 176 +++- internal/translator/kiro/common/constants.go | 9 +

Skip merging tool role messages in MergeAdjacentMessages() to preserve individual tool_call_id fields 2. Track pendingToolResults and attach to the next user message instead of only the last message. Create synthetic user message when conversation ends with tool results. 3. Insert synthetic user message with tool results before assistant messages to maintain proper alternating user/assistant structure. This fixes the case where LiteLLM translates Anthropic user messages containing only tool_result blocks into tool role messages followed by assistant. Adds unit tests covering all tool result handling scenarios. --- .../translator/kiro/common/message_merge.go | 7 + .../kiro/openai/kiro_openai_request.go | 47 ++-

internal/translator/kiro/claude/tool_compression.go - calculateToolsSize(): 计算工具列表的 JSON 序列化大小 - simplifyInputSchema(): 简化 input_schema，递归处理嵌套 properties - compressToolDescription(): 按比例压缩描述，支持 UTF-8 安全截断 - compressToolsIfNeeded(): 主压缩函数，实现两步压缩策略 - internal/translator/kiro/claude/tool_compression_test.go - 完整的单元测试覆盖所有新增函数 - 测试 UTF-8 安全性 - 测试压缩效果 ## 修改文件 - internal/translator/kiro/common/constants.go - 新增 ToolCompressionTargetSize = 20KB (压缩目标大小阈值) - 新增 MinToolDescriptionLength = 50 (描述最短长度) - internal/translator/kiro/claude/kiro_claude_request.go - 在 convertClaudeToolsToKiro() 函数末尾调用 compressToolsIfNeeded() ## 测试结果 - 70KB 工具压缩至 17KB (74.7% 压缩率) - 所有单元测试通过 ## 预期效果 - 80KB+ tools 压缩至 ~15KB - 不影响工具调用功能 --- .../kiro/claude/kiro_claude_request.go | 6 +- .../kiro/claude/tool_compression.go | 197 ++++++++++++++++++ internal/translator/kiro/common/constants.go | 10 +- 3 files changed, 211 insertions(+), 2 deletions(-) create mode 100644 internal/translator/kiro/claude/tool_compression.go diff --git a/internal/translator/kiro/claude/kiro_claude_request.go b/internal/translator/kiro/claude/kiro_claude_request.go index 402591e7..06141a29 100644 --- a/internal/translator/kiro/claude/kiro_claude_request.go +++ b/internal/translator/kiro/claude/kiro_claude_request.go @@ -520,7 +520,7 @@ func convertClaudeToolsToKiro(tools gjson.Result) []KiroToolWrapper { log.Debugf("kiro: tool '%s' has empty description, using default: %s", name, description) } -
