 可通过配置中的 `claude_mapping` 或 `claude_model_mapping` 覆盖映射关系。
 另外，`/anthropic/v1/models` 现已包含 Claude 1.x/2.x/3.x/4.x 历史模型 ID 与常见别名，便于旧客户端直接兼容。
 
+
+#### Claude Code 接入避坑（实测）
+
+- `ANTHROPIC_BASE_URL` 推荐直接指向 DS2API 根地址（例如 `http://127.0.0.1:5001`），Claude Code 会请求 `/v1/messages?beta=true`。
+- `ANTHROPIC_API_KEY` 需要与 `config.json` 中 `keys` 一致；建议同时保留常规 key 与 `sk-ant-*` 形态 key，兼容不同客户端校验习惯。
+- 若系统设置了代理，建议对 DS2API 地址配置 `NO_PROXY=127.0.0.1,localhost,<你的主机IP>`，避免本地回环请求被代理拦截。
+- 如遇“工具调用输出成文本、未执行”问题，请升级到包含 Claude 工具调用多格式解析（JSON/XML/ANTML/invoke）的版本。
+
 ### Gemini 接口
 
 Gemini 适配器将模型名通过 `model_aliases` 或内置规则映射到 DeepSeek 原生模型，支持 `generateContent` 和 `streamGenerateContent` 两种调用方式，并完整支持 Tool Calling（`functionDeclarations` → `functionCall` 输出）。

 Override mapping via `claude_mapping` or `claude_model_mapping` in config.
 In addition, `/anthropic/v1/models` now includes historical Claude 1.x/2.x/3.x/4.x IDs and common aliases for legacy client compatibility.
 
+
+#### Claude Code integration pitfalls (validated)
+
+- Set `ANTHROPIC_BASE_URL` to the DS2API root URL (for example `http://127.0.0.1:5001`). Claude Code sends requests to `/v1/messages?beta=true`.
+- `ANTHROPIC_API_KEY` must match an entry in `keys` from `config.json`. Keeping both a regular key and an `sk-ant-*` style key improves client compatibility.
+- If your environment has proxy variables, set `NO_PROXY=127.0.0.1,localhost,<your_host_ip>` for DS2API to avoid proxy interception of local traffic.
+- If tool calls are rendered as plain text and not executed, upgrade to a build that includes multi-format Claude tool-call parsing (JSON/XML/ANTML/invoke).
+
 ### Gemini Endpoint
 
 The Gemini adapter maps model names to DeepSeek native models via `model_aliases` or built-in heuristics, supporting both `generateContent` and `streamGenerateContent` call patterns with full Tool Calling support (`functionDeclarations` → `functionCall` output).

+# Tool call parsing semantics (Go canonical spec)
+
+This document defines the cross-runtime contract for `ParseToolCallsDetailed` / `parseToolCallsDetailed`.
+
+## Output contract
+
+- `calls`: accepted tool calls with normalized tool names.
+- `sawToolCallSyntax`: true when tool-call-like syntax is detected (`tool_calls`, `<tool_call>`, `<function_call>`, `<invoke>`) or a valid call is parsed.
+- `rejectedByPolicy`: true when parser extracted call syntax but all calls are rejected by allow-list policy.
+- `rejectedToolNames`: de-duplicated rejected tool names in first-seen order.
+
+## Parse pipeline
+
+1. Strip fenced code blocks for non-standalone parsing.
+2. Build candidates from:
+   - full text,
+   - fenced JSON snippets,
+   - extracted JSON objects around `tool_calls`,
+   - first `{` to last `}` object slice.
+3. Parse each candidate in order:
+   - JSON payload parser (`tool_calls`, list, single call object),
+   - XML/Markup parser (`<tool_call>`, `<function_call>`, `<invoke>`; supports attributes + nested fields),
+   - Text KV fallback parser (`function.name: <name>` ... `function.arguments: {json}`).
+4. Stop at first candidate that yields at least one call.
+
+## Name normalization policy
+
+When matching parsed names against configured tools:
+
+1. exact match,
+2. case-insensitive match,
+3. namespace tail match (`a.b.c` => `c`),
+4. loose alnum match (remove non `[a-z0-9]`, compare).
+
+## Standalone mode
+
+Standalone mode (`ParseStandaloneToolCallsDetailed`) parses the whole input directly (no candidate slicing), while still applying:
+
+- example-context guard,
+- JSON then markup fallback,
+- the same allow-list normalization policy.

+# DeepSeek Function Calling 缺陷分析与 ds2api 的增强修复策略
+
+> **相关 PR**: #74 (代码核心实现) 与 #75 (Merge to dev)
+> **问题背景**: 解决因包括 DeepSeek 在内的部分模型在函数调用（Function Calling/Tool Call）表现不够“规范”，从而导致工具调用失败的问题。
+
+## 一、底层架构对比：为什么会产生 Function Calling 缺陷？
+
+在探讨缺陷前，我们需要理解两种 Function Calling 的底层结构差异：
+
+### 1. OpenAI 的原生结构化返回 (API 级分离)
+在 OpenAI 的规范中，**聊天文字与工具调用是在底层的 JSON 结构中被硬性拆分的**：
+* 聊天废话存放在 `response.choices[0].message.content` 里。
+* 工具请求存放在单独的数组 `response.choices[0].message.tool_calls` 里。
+
+**优势：** 这种设计对客户端极其友好。客户端只需判断 `tool_calls` 是否为空，就能决定是执行代码还是渲染文字。它支持同时并发多个工具请求，且底层的生成殷勤被严格训练和约束，极少抛出语法错误的 JSON。
+
+### 2. DeepSeek 等模型的“单文本流”机制
+相比之下，部分未经深度专门微调的模型（或者在特定的通信适配层中），它们依然倾向于把一切内容打包成一个纯文本流吐出。这就是为什么它们的输出往往不仅包含了本该属于 `tool_calls` 结构里的 JSON，还会像个“老实人”一样夹杂了属于 `content` 里的散文。
+
+---
+
+## 二、DeepSeek 在 Function Calling 上的特定缺陷表现
+
+相比于 OpenAI 严格遵循 API 约定的原生结构，DeepSeek 等开源/国产推理模型在工具调用时，经常会暴露出以下三种典型的“不守规矩”的输出行为：
+
+### 1. 混合输出：散文文本与工具 JSON 混杂 (Mixed Prose Streams)
+当应用要求模型直接返回工具请求时，DeepSeek 有时候会**“忍不住想和用户搭话”**。
+它常常前置一段解释性废话，中间插入工具调用的 JSON 参数，并在末尾再补上一句总结：
+```text
+好的，我这就帮你读取 README.md 的内容：
+{"tool_calls":[{"name":"read_file","input":{"path":"README.md"}}]}
+请稍等片刻，我马上把它读出来。
+```
+**旧版系统痛点：**
+原有的代码存在**严格模式（Strict Mode）**校验：
+```go
+// 如果解析到的 JSON 块前后存在任何非空字符串，就放弃当作工具调用！
+if strings.TrimSpace(state.recentTextTail) != "" || strings.TrimSpace(prefixPart) != "" ... {
+    return captured, nil, "", true
+}
+```
+这直接导致上述结构被网关认定是一段“普通聊天”，直接原封不动地返回给用户，这直接干挂了后续的工具自动执行流程。
+
+### 2. 工具名格式幻觉：擅自修改或前缀化工具名称
+由于 DeepSeek 的预训练数据中有大量的代码和不同的平台结构，它在回复工具名称时，常常无法忠实于 System Prompt 中提供的纯命名（也就是 `name: "read_file"`），而是加上前缀或者拼写变形，例如：
+* `{"name": "mcp.search_web"}` （自带命名空间）
+* `{"name": "tools.read_file"}`
+* `{"name": "search-web"}` （下划线变成了中划线）
+
+**旧版系统痛点：**
+旧版系统对于工具名的匹配几乎只有“绝对相等”的字典级比对，只要差了一个字符或加了前缀，就会由于找不到合法工具而直接失败。
+
+### 3. Role 角色的非标准返回
+在部分工具通信流的响应中，返回的内容其所属的 `role` 没有被标准化处理，可能携带意料之外的属性，或是与下游严格比对出现冲突。
+
+---
+
+## 二、PR #74 的代码增强修复方案
+
+为了解决大模型这种自身的不规范行为，PR #74 在系统的中间层网关联入了一个**极其包容的容错引擎**。它并不强制要求模型“改过自新”，而是主动做了以下三块增强：
+
+### 1. 从流中分离混合内容（废除 Strict Mode）
+修改了 `internal/adapter/openai/tool_sieve_core.go`。
+取消了前后包裹文本的拦截逻辑。当系统扫描到流式结构中有完整的 `{"tool_calls":...}` 时，它会将废话和 JSON 分发到不同的事件流中：
+```go
+if prefix != "" {
+    // 将前面的“好的，帮你读文件”剥离出来作为常规文本输出
+    state.noteText(prefix)
+    events = append(events, toolStreamEvent{Content: prefix})
+}
+// 捕获并拦截中间的工具请求，进行背后执行
+state.pendingToolCalls = calls
+```
+**效果：** 用户的屏幕上只能看到正常的文字交流，而后端的工具也会立刻挂载。
+
+### 2. 多级宽容匹配引擎 (Resolve Allowed Tool Name)
+在 `internal/util/toolcalls_parse.go` 中，新增了一个由严到松降级匹配的强大漏斗策略函数 `resolveAllowedToolName`：
+
+1. **绝对匹配**：和以前一样，`read_file` == `read_file`。
+2. **忽略大小写**：`Read_File` 算作合法。
+3. **命名空间抹除**：通过寻找最后一个 `.` 来剥离前缀，强制将 `mcp.search_web` 还原出真实的 `search_web`。
+4. **终极正则清洗**：
+   引入 `var toolNameLoosePattern = regexp.MustCompile(`[^a-z0-9]+`)`。
+   这个正则剥离了字符串里所有的符号、空格、格式符。
+   将传入的 `read-file` 洗除符号成为 `readfile`，并去和系统中所有合法工具同样清洗后的版本进行比较。只要核心字母一致，即算作匹配成功。
+
+### 3. Role 归一化 (Normalize OpenAIRoleForPrompt)
+在 `internal/adapter/openai/responses_input_items.go` 等处，引入了特定的 `normalizeOpenAIRoleForPrompt(role)` 清洗，保证输入和传递给上游的 Role 枚举始终受控，消除了因为意外的身份字段传参崩溃。
+
+---
+
+## 报告总结与 tool_sieve 的本质作用
+
+PR #74 / #75 并没有从模型本身开刀，而是基于**网关应足够健壮**的设计哲学。
+
+**其实整个增强实现，本质上实现了一个名为 `tool_sieve` (工具筛子) 的中间层网关。**
+面对 DeepSeek 这种吐出一团混合了聊天文字与 JSON 面团的“不标准”数据流，`tool_sieve` 就像一个勤劳的高精度筛子，不仅人工揉开了面团：
+1. 它把散文分拣出来，塞回标准结构的 `content` 字段去展示；
+2. 剥离并清洗出有瑕疵的 JSON 块，按照 OpenAI 的标准格式小心翼翼地放进 `tool_calls` 结构里去等待执行。
+
+这意味着，即便 AI 被配置了奇怪的回复设定、加粗了强调语言，甚至是犯了标点符号拼写小失误，**只要它输出了可以拼凑成工具指令的 JSON 核心单元，整个中继层就能将其挽救，并把正确的工具结果呈现给模型和用户**。 这不仅修复了缺陷，更极大地增强了工具网关的通用性和鲁棒性。
