From 90be75ff9faaf5dc930ee4f0de5be37f916c1532 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=E5=B0=8F=E6=B5=B7?= <7836246@qq.com> Date: Fri, 20 Mar 2026 09:14:28 +0800 Subject: [PATCH] feat: add tool passthrough mode, identity leak sanitization & enhanced tool_choice=any 1. Tool passthrough mode (config: tools.passthrough: true) - Bypasses multi-namespace few-shot injection - Embeds raw tool definitions in tags with minimal 1-shot example - Cleans conflicting client prompts (provider-native tool calling, XML markup) - Ideal for Roo Code / Cline clients 2. Enhanced Cursor identity leak sanitization - New refusal detection patterns for "currently in Cursor context" leaks - 4 new sanitizeResponse regexes targeting full context leak paragraphs - Covers "I apologize - it appears I'm in Cursor support assistant context" 3. Enhanced tool_choice=any force message - Lists available tool names (up to 15) with format example - Uses collaborative guidance tone to avoid triggering refusal - Stream and non-stream paths aligned --- src/config.ts | 1 + src/constants.ts | 4 + src/converter.ts | 388 +++++++++++++++++++++++++++++++---------------- src/handler.ts | 61 +++++++- src/types.ts | 1 + 5 files changed, 323 insertions(+), 132 deletions(-) diff --git a/src/config.ts b/src/config.ts index 2797ee5..234175e 100644 --- a/src/config.ts +++ b/src/config.ts @@ -89,6 +89,7 @@ function parseYamlConfig(defaults: AppConfig): { config: AppConfig; raw: Record< descriptionMaxLength: typeof t.description_max_length === 'number' ? t.description_max_length : 0, includeOnly: Array.isArray(t.include_only) ? t.include_only.map(String) : undefined, exclude: Array.isArray(t.exclude) ? t.exclude.map(String) : undefined, + passthrough: t.passthrough === true, }; } // ★ 响应内容清洗开关（默认关闭） diff --git a/src/constants.ts b/src/constants.ts index 8963ef0..0aca2f8 100644 --- a/src/constants.ts +++ b/src/constants.ts @@ -85,6 +85,10 @@ export const REFUSAL_PATTERNS: RegExp[] = [ /(?:can[.']?t|cannot|unable\s+to)\s+help\s+with\s+(?:this|that)\s+(?:request|question|topic)/i, /scoped\s+to\s+(?:answering|helping)/i, + // ── English: Cursor support assistant context leak (2026-03) ── + /currently\s+in\s+(?:the\s+)?Cursor\s+(?:support\s+)?(?:assistant\s+)?context/i, + /it\s+appears\s+I['']?m\s+currently\s+in\s+the\s+Cursor/i, + // ── 中文: 身份拒绝 ── /我是\s*Cursor\s*的?\s*支持助手/, /Cursor\s*的?\s*支持系统/, diff --git a/src/converter.ts b/src/converter.ts index 14cbeea..fb6fd18 100644 --- a/src/converter.ts +++ b/src/converter.ts @@ -180,6 +180,26 @@ ${behaviorRules}${forceConstraint}`; // ==================== 请求转换 ==================== +/** + * 为工具生成备用参数（用于拒绝清洗时的占位工具调用） + */ +function generateFallbackParams(tool: AnthropicTool): Record { + if (/^(Read|read_file|ReadFile)$/i.test(tool.name)) return { file_path: 'src/index.ts' }; + if (/^(Bash|execute_command|RunCommand|run_command)$/i.test(tool.name)) return { command: 'ls -la' }; + if (/^(Write|write_to_file|WriteFile|write_file)$/i.test(tool.name)) return { file_path: 'output.txt', content: '...' }; + if (/^(ListDir|list_dir|list_directory|ListDirectory|list_files)$/i.test(tool.name)) return { path: '.' }; + if (/^(Search|search_files|SearchFiles|grep_search|codebase_search)$/i.test(tool.name)) return { query: 'TODO' }; + if (/^(Edit|edit_file|EditFile|replace_in_file)$/i.test(tool.name)) return { file_path: 'src/main.ts', old_text: 'old', new_text: 'new' }; + if (tool.input_schema?.properties) { + return Object.fromEntries( + Object.entries(tool.input_schema.properties as Record) + .slice(0, 2) + .map(([k, v]) => [k, v.type === 'boolean' ? true : v.type === 'number' ? 1 : 'value']) + ); + } + return { input: 'value' }; +} + /** * Anthropic Messages API 请求 → Cursor /api/chat 请求 * @@ -237,143 +257,255 @@ export async function convertToCursorRequest(req: AnthropicRequest): Promise ['attempt_completion', 'ask_followup_question', 'AskFollowupQuestion'].includes(t.name)); - let toolInstructions = buildToolInstructions(tools, hasCommunicationTool, toolChoice); + if (isPassthrough) { + // ★ 透传模式：直接嵌入原始工具定义，跳过 few-shot 注入 + // 目的：减少与 Cursor 内建身份的提示词冲突 + // 适用：Roo Code、Cline 等非 Claude Code 客户端 + console.log(`[Converter] 透传模式: ${tools.length} 个工具直接嵌入`); - // ★ 有工具时：thinking 提示放在工具指令末尾（模型注意力最强的位置之一） - if (thinkingEnabled) { - toolInstructions += thinkingHint; - } + // 构建工具定义的 JSON 清单（保留原始 Anthropic 格式） + const toolDefs = tools.map(t => { + const def: Record = { name: t.name }; + if (t.description) def.description = t.description; + if (t.input_schema) def.input_schema = t.input_schema; + return def; + }); - // 系统提示词与工具指令合并 - toolInstructions = combinedSystem + '\n\n---\n\n' + toolInstructions; + // tool_choice 约束 + let forceConstraint = ''; + if (toolChoice?.type === 'any') { + forceConstraint = '\n\n**MANDATORY**: Your response MUST include at least one tool call using the ```json action``` format above.
