+# AGENTS.md
+
+Behavioral guidelines to reduce common LLM coding mistakes. Merge with project-specific instructions as needed.
+
+**Tradeoff:** These guidelines bias toward caution over speed. For trivial tasks, use judgment.
+
+**Important:** Use Chinese for information responses and thinking; use English for searching and querying.
+
+## 1. Think Before Coding
+
+**Don't assume. Don't hide confusion. Surface tradeoffs.**
+
+Before implementing:
+- State your assumptions explicitly. If uncertain, ask.
+- If multiple interpretations exist, present them - don't pick silently.
+- If a simpler approach exists, say so. Push back when warranted.
+- If something is unclear, stop. Name what's confusing. Ask.
+
+## 2. Simplicity First
+
+**Minimum code that solves the problem. Nothing speculative.**
+
+- No features beyond what was asked.
+- No abstractions for single-use code.
+- No "flexibility" or "configurability" that wasn't requested.
+- No error handling for impossible scenarios.
+- If you write 200 lines and it could be 50, rewrite it.
+
+Ask yourself: "Would a senior engineer say this is overcomplicated?" If yes, simplify.
+
+## 3. Surgical Changes
+
+**Touch only what you must. Clean up only your own mess.**
+
+When editing existing code:
+- Don't "improve" adjacent code, comments, or formatting.
+- Don't refactor things that aren't broken.
+- Match existing style, even if you'd do it differently.
+- If you notice unrelated dead code, mention it - don't delete it.
+
+When your changes create orphans:
+- Remove imports/variables/functions that YOUR changes made unused.
+- Don't remove pre-existing dead code unless asked.
+
+The test: Every changed line should trace directly to the user's request.
+
+## 4. Goal-Driven Execution
+
+**Define success criteria. Loop until verified.**
+
+Transform tasks into verifiable goals:
+- "Add validation" → "Write tests for invalid inputs, then make them pass"
+- "Fix the bug" → "Write a test that reproduces it, then make it pass"
+- "Refactor X" → "Ensure tests pass before and after"
+
+For multi-step tasks, state a brief plan:
+```
+1. [Step] → verify: [check]
+2. [Step] → verify: [check]
+3. [Step] → verify: [check]
+```
+
+Strong success criteria let you loop independently. Weak criteria ("make it work") require constant clarification.
+
+---
+
+**These guidelines are working if:** fewer unnecessary changes in diffs, fewer rewrites due to overcomplication, and clarifying questions come before implementation rather than after mistakes.
+
+## Agent skills
+
+### Issue tracker
+
+Issues and specs live as local markdown files under `.scratch/`. See `docs/agents/issue-tracker.md`.
+
+### Triage labels
+
+The five canonical triage roles use their default label strings. See `docs/agents/triage-labels.md`.
+
+### Domain docs
+
+Single-context repo with `CONTEXT.md` and `docs/adr/` at the root. See `docs/agents/domain.md`.

+
+## [0.6.1] - 2026-08-18
+
+### 🔧 其他变更
+- 依赖瘦身：移除未使用的直接依赖 `config`、`handlebars`、`shell-words`、`walkdir`、`console`、`lazy_static`、`atty`，crate 总数由 341 降至 296，release 二进制体积由 7.38 MB 降至 7.00 MB（-5.2%）
+- `lazy_static!` 宏替换为标准库 `LazyLock`；`atty` 替换为标准库 `std::io::IsTerminal`
+- `tokio` 特性由 `full` 精简为 `macros` + `rt-multi-thread`
+- `regex` 关闭默认 unicode 特性（保留 `std` + `perf`），行为变化：`\s`/`\d`/`\w` 字符类仅匹配 ASCII，对提交信息、版本号、邮箱、GPG Key ID 校验无实质影响
+
+## [0.6.0] - 2026-08-17
+
+### ✨ 新功能
+- LLM 层整体迁移至 rig-core 0.41：六家 provider（Ollama / OpenAI / Anthropic / Kimi / DeepSeek / OpenRouter）统一由 rig 原生客户端驱动，删除约 2100 行手写 HTTP/SSE/重试代码
+- 新 LLM 门面（`src/llm/rig/`）：provider 枚举 + 单一生成入口 + 凭据校验（rig VerifyClient）+ 错误映射层；提示词与提交解析拆分至独立模块
+- Anthropic 支持自定义 `base_url`（此前被静默忽略，本次修复）
+- 新增基于 rig mock 后端的 LLM 层离线测试（请求形状、流式事件、错误映射），并附 6 家 provider 的 `#[ignore]` 实网冒烟用例
+
+### 🐞 错误修复
+- 各 provider 超时统一由 `llm.timeout` 配置控制（此前默认超时 60/120/300 秒不一致）
+- 消除 Ollama 客户端构造时的 panic（`expect` 式构造）
+
+### 🔧 其他变更（行为变化）
+- Ollama 请求端点由 `/api/generate` 改为 `/api/chat`（功能等价；自定义 Ollama 代理需兼容 chat 端点）
+- 非流式请求不再做应用层重试（此前按错误文案字符串匹配重试 3 次）；流式请求由 rig 的 SSE 机制自动重连
+- 可用性校验端点变化：DeepSeek 改为 `/user/balance`、OpenRouter 改为 `/key`、Anthropic 改为 `/v1/models`（对外表现为 `LLM provider 'xxx' is not available` 语义不变）
+- 依赖瘦身：移除 `reqwest`(0.12) 与 `async-trait` 直接依赖，不引入 rig agent/fastembed/lancedb 等组件
+
+## [0.5.0] - 2026-07-24
+
+### ✨ 新功能
+- `commit` 命令新增 `.gitignore` 文件过滤：自动暂存与 `--all` 模式下自动跳过被 `.gitignore` 规则匹配的文件，并清理索引中已被忽略的已跟踪文件，暂存完成后列出被移除的文件
+- `tag` 命令新增 `-A, --auto` 模式：优先从 `Cargo.toml`/`pyproject.toml` 读取项目版本，回退到基于 commit 的语义化升级分析（与 `--bump` 互斥）
+- `changelog` 命令在未指定 `--from` 时，自动检测现有 changelog 中最高版本对应的 tag 作为起始点
+- 新增 `parse_changelog_versions()`，按 semver 降序提取 changelog 中已有的版本
+- 新增 `sort_tags_by_semver()`，取代纯时间排序，按语义版本正确排序标签
+
+### 🐞 错误修复
+- 修复 `get_tags()` 对 annotated tag 的解析：改用 `find_object`+`peel_to_commit` 正确取得标签指向的 commit
+- 修复 `changelog` 写入时 `insert_changelog_entry` 覆盖已有章节的问题，现保留现有内容并按版本插入新条目
+
+### 📚 文档
+- 同步更新 README（中/英文）：补充 `--think`、`tag --auto` 选项说明，移除已废弃的 `--prepend` 参数，修正 `set-llm` 的 `--base-url` 选项名
+
+### 🔧 其他变更
+- 新增 `TagInfo::version_name()` 与 `GitRepo::find_tag_by_version()` 辅助方法
+- 新增 `tests/gitignore_tests.rs`，包含 7 个测试覆盖 `.gitignore` 过滤逻辑
+
+## [0.4.0] - 2026-07-16

+- 新增 `host_to_service()` 主机名映射，将 github.com、gitlab.com、bitbucket.org 等常见托管平台映射为规范化服务名
+- 新增 `get_pat_for_host()` 公共 API，支持从已保存的凭据中提取 PAT 用于登录验证
+- 凭据存储复用现有基于系统密钥环的 PAT 与用户绑定逻辑，按 profile 维度管理
+
+### 🐞 错误修复
+- 移除 `keyring.rs` 中的调试 `eprintln!` 输出，避免污染 credential helper 的 stderr
+
+### 📚 文档
+- README（中/英文）新增 credential 命令使用说明
+
+### 🔧 其他变更

+- `src/main.rs` 重构为使用 `quicommit::` 库导入
+- credential 命令及其子命令均使用 `#[command(hide = true)]` 隐藏，不在 `--help` 中显示
+- 新增 `tests/credential_tests.rs`，包含 52 个测试用例覆盖协议解析、帮助可见性、完整存取周期及边界场景

+### Git Credential Helper
+
+QuiCommit can act as a Git credential helper to securely store and retrieve
+Personal Access Tokens (PATs) via the system keyring. The `credential` command
+is hidden from `--help` because it is invoked automatically by Git, not by end
+users.
+
+#### Setup
+
+Register QuiCommit as a credential helper for Git:
+
+```bash
+# Use the default QuiCommit config
+git config --global credential.helper quicommit
+
+# Or specify a custom config file
+git config --global credential.helper "quicommit --config /path/to/config.toml"
+```
+
+You can also limit the helper to a specific host:
+
+```bash
+git config --global credential.https://github.com.helper quicommit
+```
+
+#### How It Works
+
+When Git needs credentials (e.g. pushing to a remote), it calls the helper
+following the [gitcredentials protocol](https://git-scm.com/docs/gitcredentials):
+
+1. **`get`** — Git asks QuiCommit for a stored PAT matching the requested host.
+   QuiCommit searches all configured profiles in the keyring and returns the
+   PAT (plus username) if found.
+2. **`store`** — After a successful authentication (e.g. you entered a PAT in
+   the Git prompt), Git asks QuiCommit to save it. The PAT is stored in the
+   system keyring, bound to the matching profile.
+3. **`erase`** — Git asks QuiCommit to delete a stored PAT for the given host.
+
+Host names are mapped to canonical service names (`github.com` → `github`,
+`gitlab.com` → `gitlab`, `bitbucket.org` → `bitbucket`, etc.). Unknown hosts
+are used as-is.
+
+#### Removing Stored Credentials
+
+To remove a stored PAT, you can either use Git's built-in mechanism:
+
+```bash
+echo "protocol=https
+host=github.com" | git credential reject
+```
+
+Or remove it via the profile token management command:
+
+```bash
+quicommit profile token
+```
+

-- **智能标签管理**：基于语义版本自动检测升级，AI生成标签信息
+- **智能标签管理**：基于语义版本自动检测升级，AI生成标签信息；支持从 16+ 种项目配置文件（Cargo.toml、package.json、pom.xml、pubspec.yaml 等）自动读取版本
 - **变更日志生成**：自动生成Keep a Changelog格式的变更日志
-- **安全保护**：加密存储敏感数据
+- **安全保护**：使用系统密钥环进行安全存储
 - **交互式界面**：美观的CLI界面，支持预览和确认
+- **多语言支持**：支持7种语言输出（中文、英语、日语、韩语、西班牙语、法语、德语）
+- **配置导出导入**：备份和恢复配置，支持加密保护

+### Git 凭据助手（Credential Helper）
+
+QuiCommit 可以作为 Git 凭据助手，通过系统密钥环安全地存储和读取个人访问令牌（PAT）。
+`credential` 命令在 `--help` 中是隐藏的，因为它由 Git 自动调用，无需用户手动执行。
+
+#### 配置方法
+
+将 QuiCommit 注册为 Git 凭据助手：
+
+```bash
+# 使用默认的 QuiCommit 配置
+git config --global credential.helper quicommit
+
+# 或指定自定义配置文件路径
+git config --global credential.helper "quicommit --config /path/to/config.toml"
+```
+
+也可以仅对特定主机启用：
+
+```bash
+git config --global credential.https://github.com.helper quicommit
+```
+
+#### 工作原理
+
+当 Git 需要凭据（例如推送到远程仓库）时，会按照
+[gitcredentials 协议](https://git-scm.com/docs/gitcredentials) 调用助手：
+
+1. **`get`** — Git 向 QuiCommit 请求与目标主机匹配的已存储 PAT。
+   QuiCommit 在所有已配置的 profile 中搜索密钥环，找到则返回 PAT（及用户名）。
+2. **`store`** — 认证成功后（例如你在 Git 提示中输入了 PAT），Git 要求
+   QuiCommit 保存该凭据。PAT 将存入系统密钥环，并与匹配的 profile 绑定。
+3. **`erase`** — Git 要求 QuiCommit 删除指定主机的已存储 PAT。
+
+主机名会被映射为规范化的服务名（`github.com` → `github`、`gitlab.com` →
+`gitlab`、`bitbucket.org` → `bitbucket` 等），未知主机则原样使用。
+
+#### 删除已存储的凭据
+
+可以通过 Git 内置机制删除已存储的 PAT：
+
+```bash
+echo "protocol=https
+host=github.com" | git credential reject
+```
+
+也可以通过 profile 令牌管理命令删除：
+
+```bash
+quicommit profile token
+```
+
