The chat and model +management surfaces are usable, while local image generation is still +experimental and should be tested per device and model bundle. + +Current release status: + +- Alpha APKs are published through + [GitHub Releases](https://github.com/lyydfys/MCA/releases). +- The first public package target is `arm64-v8a` Android devices. +- Local chat is the primary stable local path. +- Web search is available after the user configures a search provider in + Settings. MCA supports manual, smart-auto, and always-on trigger modes for + SearxNG, Brave Search, Tavily, Jina Search, and custom JSON search endpoints. +- Local image generation is experimental and requires complete model bundles. + Do not treat phone-side image generation as a guaranteed stable feature yet. + +## Features + +- **Local chat**: native `llama.cpp` bridge, streaming generation, stop support, + token speed labels, reasoning-content filtering, and local benchmark support. +- **Cloud chat**: user-configured OpenAI-compatible or Anthropic Messages + endpoints with locally encrypted API key storage. +- **Smart web search**: user-configured SearxNG, Brave Search, Tavily, Jina + Search, or custom JSON search providers. MCA can identify URLs, detect + explicit search intent, expand time-sensitive or documentation-style queries, + rank/deduplicate sources, summarize results into the current turn only, and + display source cards under the assistant reply. Trigger modes are manual, + smart-auto, and always-on; the Settings page keeps recent local search + diagnostics for trigger reasons, closed-loop evidence, provider errors, + partial expanded-query warnings, expanded queries, source counts, latency, + clickable source URLs, provider labels, source snippets, and a local source + quality score based on usable sources, readable content length, independent + hosts, and safety blocks. Direct URL + reading works after web search is enabled even before a search API is + configured; keyword search still requires SearxNG, Brave, Tavily, Jina, or a + custom JSON endpoint. Custom JSON endpoints can use URL templates such as + `/search?q={query}&limit={max_results}` or common `q/query/max_results` + parameters. Provider endpoints may be self-hosted, but readable page fetching + and direct URL reading block localhost, private LAN, link-local, and reserved + addresses by default for safety. When Jina Search is selected with a + key, MCA can fall back to Jina Reader for public pages whose direct readable + content is too weak, while keeping the same private-network guard. MCA reads multiple + direct URLs, expanded search queries, and fetched page bodies concurrently to + keep live search responsive on mobile networks. Keyword search successes use + a short in-memory local cache to avoid repeating the same provider call within + a brief window; direct URL reads are not cached and API keys are never stored + in cache entries. The search test in Settings + uses the fields currently typed into the form, so users can verify an endpoint + before saving it. The closed-loop self-test records whether MCA produced + provider results, prompt context, source-card data, quality scoring, and local + diagnostics. Settings also includes a no-key public JSON self-check filler so + users can verify the integration path before entering their own provider. MCA + labels this source as `公开 JSON 自检源` in the app because it is only a protocol + check with limited coverage, not a general web-search engine; production use + should rely on a trusted or self-hosted search service. Custom JSON endpoints may return a top-level array, an + object containing `results`, `items`, `data`, `hits`, or `organic_results`, or nested + variants such as `data.results` and `response.items`. It accepts common URL/title fields such as + `url`, `link`, `href`, `html_url`, `story_url`, `canonical_url`, `displayLink`, + `formattedUrl`, `source.url`, `title`, `full_name`, `story_title`, and + `source.title`, plus summary/body fields such as `summary`, `excerpt`, and + `pageContent`. When smart query expansion creates multiple + searches, MCA keeps successful sources even if one expanded query fails. + Tavily and Jina use `Authorization: Bearer `; Brave uses + `X-Subscription-Token` and supports both the Web Search endpoint and the + LLM Context endpoint for AI grounding/RAG-style snippets. Public SearxNG + instances often rate-limit or disable JSON responses, so a self-hosted or + explicitly approved endpoint is recommended for reliable search. + Brave and Tavily official API root URLs are accepted and normalized to their + search paths during preflight and request execution. +- **Image page**: MCA image workspace with local/cloud engine switching, + prompt composer, generation states, template cards, and image library. +- **Local image engines**: `stable-diffusion.cpp` bridge with progress/cancel + hooks and bundle-aware model registration. +- **Model hub**: local/imported models, ModelScope recommendations, resumable + downloads, file classification, and engine grouping. +- **Assistants and role cards**: multiple local assistants with system prompts, + default model preference, generation parameters, memory/search toggles, and + JSON role-card import/export. MCA exports its own `mca.assistant.card` schema + and can import common nested character-card `data` fields into a usable + system prompt. +- **Agent diagnostics**: local device profiling, model recommendations, + benchmark-based tuning, and explainable parameter plans. +- **Local API**: OpenAI-compatible local server for trusted same-device and + same-LAN clients, including `/v1/models`, `/v1/chat/completions`, JSON + replies, and SSE streaming. + +## Install + +Download the latest alpha APK from +[GitHub Releases](https://github.com/lyydfys/MCA/releases). Android may ask you +to allow installation from your browser or file manager. + +The APK does not include model weights or cloud credentials. After installing: + +1. Add a local GGUF chat model or configure a cloud chat engine. +2. Configure an image engine if you want cloud or local image generation. +3. Configure web search in Settings if you want live search. You can use a + self-hosted SearxNG endpoint, Brave Search, Tavily, Jina Search, or a + compatible custom JSON endpoint, test the current form values, then choose + manual, smart-auto, or always-on triggering. Brave can use either + `/res/v1/web/search` for normal search or `/res/v1/llm/context` for + grounding-oriented snippets; Brave/Tavily official root URLs are auto-filled + to the normal search paths. Direct page reading will refuse + localhost, LAN, link-local, and reserved addresses unless a development build + explicitly enables private-network fetching. See + [docs/WEB_SEARCH.md](docs/WEB_SEARCH.md) for the full configuration, + trigger-mode, source-card, and troubleshooting guide. + Quick source guide: choose Tavily or Brave for the fastest API-key setup, + choose self-hosted SearxNG when privacy and control matter most, choose Jina + when page-body extraction needs help, or choose custom JSON when you operate + your own search gateway. +4.

MCA does not bundle +provider keys or model weights. + +## Web Search + +Web search is disabled until the user configures and enables a search provider +in Settings. MCA supports manual, smart-auto, and always-on trigger modes. When +a turn triggers keyword web search, MCA sends the search query to the configured +SearxNG, Brave Search, Tavily, Jina Search, or custom JSON endpoint, then injects a shortened +source summary into that turn only. If the user provides a direct URL, MCA can +read that page after web search is enabled even when no search API is configured. +Source URLs may be fetched to improve answer quality when page fetching is +enabled. Provider endpoints may be self-hosted, but readable page fetching and +direct URL reading block localhost, private LAN, link-local, and reserved +addresses by default for safety. When Jina Search is selected with a key, MCA +may use Jina Reader to retrieve cleaned Markdown for public pages whose direct +readable content is too weak; this does not bypass the private-network guard. +Multiple direct URLs, expanded search queries, and fetched page bodies are read +concurrently to reduce latency. Successful keyword searches may be kept in a +short in-memory local cache to reduce repeated provider requests; direct URL +reads are not cached, and cache entries do not contain API keys. Search provider API keys are stored on device and encrypted with Android Keystore when +available. Recent search diagnostics are stored locally for troubleshooting and +can be cleared from the web search settings page; they include queries, status +summaries, latency, trigger reasons, partial expanded-query warnings, source +counts, source URLs, provider labels, source snippets, and closed-loop evidence +showing whether prompt context and source-card data were produced, but not API keys. +MCA also computes a local source quality score from +usable source count, readable content length, independent hosts, and safety +blocks; this score is used for diagnostics and prompt caution only. The web +search test in Settings uses the current form values, so it can verify a +provider or direct URL reading before saving the configuration or loading any +chat model. The closed-loop self-test simulates one chat turn and records +provider results, prompt context, source-card data, quality scoring, and cache +status. The optional public JSON self-check filler uses a no-key public endpoint +only to verify the integration path; user questions typed for that test are sent +to that endpoint just like any configured provider. Custom JSON endpoints may return a top-level array, an object +containing `results`, `items`, `data`, `hits`, or `organic_results`, or nested variants +such as `data.results`; common URL and title fields such as `html_url`, +`story_url`, `full_name`, and `story_title` are accepted. When smart query expansion creates multiple searches, +MCA keeps successful sources even if one expanded query fails. Public SearxNG instances may rate-limit, block automated +JSON requests, or change policy without notice; use a self-hosted SearxNG +instance, Brave Search, Tavily, Jina Search, or another trusted endpoint for +reliable keyword search. + +## Diagnostics + +Diagnostic logs are local files.

API。只有“关键词搜索”“最新资料”“调研对比”这类需要全网检索的问题，才需要配置下面任意一种搜索源。 + +| 适合谁 | 推荐搜索源 | 获取方式 | 在 MCA 里怎么填 | +|---|---|---|---| +| 想最快跑通的普通用户 | Tavily Search | 打开 [Tavily Quickstart](https://docs.tavily.com/documentation/quickstart)，注册或登录 Tavily Platform，在 Dashboard 里复制 API Key。 | 选择 `Tavily`；搜索接口地址填 `https://api.tavily.com` 或 `https://api.tavily.com/search`；API Key 填 Tavily Key。 | +| 想用独立搜索索引的用户 | Brave Search API | 打开 [Brave Search API](https://brave.com/search/api/) 或 [Brave API Quickstart](https://api-dashboard.search.brave.com/documentation/quickstart)，创建账号、订阅可用计划，然后在 Dashboard 获取 Search API Key。 | 选择 `Brave`；搜索接口地址填 `https://api.search.brave.com` 或 `https://api.search.brave.com/res/v1/web/search`；API Key 填 Brave Search API Key。 | +| 想增强网页正文读取的用户 | Jina Search | 打开 [Jina API Dashboard](https://jina.ai/api-dashboard/) 创建或管理 API Key。Jina 官方提供 `s.jina.ai` 做搜索，`r.jina.ai` 做网页读取。 | 选择 `Jina`；搜索接口地址填 `https://s.jina.ai`；API Key 填 Jina Key。 | +| 想隐私和可控优先的用户 | 自建 SearxNG | 按 [SearXNG Installation](https://docs.searxng.org/admin/installation.html) 或 [Docker 安装文档](https://docs.searxng.org/admin/installation-docker.html) 部署自己的实例；也可以临时试用 [searx.space](https://searx.space/) 上的公开实例，但公共实例可能限流、关闭 JSON 或不可用。 | 选择 `SearxNG`；地址填你的实例根地址，例如 `https://search.example.com`。多数实例不需要 API Key。 | +| 有自己后端或聚合服务的用户 | 自定义 JSON | 自己搭一个搜索网关，后端可以转发 Brave、Tavily、Jina、SearxNG 或其它搜索服务，并统一返回 JSON。 | 选择 `自定义`；地址填你的网关 URL，可使用 `/search?q={query}&limit={max_results}` 这类模板；如需鉴权，API Key 会按 Bearer 发送。 | + +推荐选择： + +- **最快上手**：先用 Tavily 或 Brave，拿到 Key 后填入 MCA，点击 `网络预检` 和 `闭环自检`。 +- **更重视隐私**：自建 SearxNG，再把实例地址填入 MCA。不要长期依赖陌生公共实例。 +- **网页正文经常读不全**：配置 Jina，MCA 会在正文抓取不足时尝试 Reader 增强。 +- **团队或高级用户**：做一个自定义 JSON 网关，统一管理 Key、限流、缓存和搜索源。 + +`公开 JSON 自检源` 只用于验证 MCA 的请求、JSON

`https://your-searxng.example` | 通常不需要 | 填实例根地址即可，MCA 会请求 `/search?format=json`。公开实例可能禁用 JSON 或限流。 | +| Brave Search | `https://api.search.brave.com`、`https://api.search.brave.com/res/v1/web/search` 或 `https://api.search.brave.com/res/v1/llm/context` | `X-Subscription-Token` | 常规搜索可直接填官方根地址，MCA 会自动补全到 `/res/v1/web/search`；需要 Brave 聚合好的 grounding 片段时可手动填写 LLM Context。不要填控制台、聊天接口或非搜索路径。 | +| Tavily Search | `https://api.tavily.com` 或 `https://api.tavily.com/search` | `Authorization: Bearer ` | 填官方根地址时，MCA 会自动补全 `/search`，并使用 POST JSON 调用。 | +| Jina Search | `https://s.jina.ai` | `Authorization:

`title`、`name`、`full_name`、`story_title`、`question`、`source.title` | +| 摘要 | `snippet`、`description`、`summary`、`excerpt`、`text`、`content` | +| 正文 | `raw_content`、`rawContent`、`body`、`page_content`、`pageContent`、`markdown`、`content_text` | + +设置页的 `填入公开 JSON 协议自检源` 只用于验证 JSON 接入、上下文注入、来源卡片和诊断链路。它不是通用搜索服务，正式使用时请配置自己的可信搜索源。如果聊天页或诊断记录显示 `公开 JSON 自检源`，说明当前还处在协议验证状态，适合做链路测试，不适合拿来搜索全网实时资料。 + +聊天页会把公开 JSON 自检源视为 `协议自检`，不会把它当作真实关键词搜索源自动使用。此时仍可读取用户消息里的公开 URL；如果要让“联网检索”真正搜索全网，需要配置 SearxNG、Brave、Tavily、Jina 或可信自建搜索网关。 + +## 判断是否真的联网成功 + +一次成功的联网回答应该同时具备： + +- 聊天回复下方有 `检索过程` 卡。 +- 来源卡里有可打开的 URL、站点名和摘要。 +- 展开过程卡能看到触发依据、检索目标、来源数量和闭环检查。 +- 设置页 `最近检索` 里能看到同一次记录。 +- 回答正文里尽量出现 `[1]`、`[2]` 这样的来源编号。 + +如果回答说“我无法联网”或“主要基于知识库”，但下方已经有来源卡，说明云端或本地模型没有完全遵守上下文。MCA 会通过提示词和引用审计尽量压制这种话术，但不同模型的服从度仍会有差异。 + +## 常见失败 + +| 现象 | 可能原因 | 处理建议 | +|---|---|---| +| `联网检索未配置` | 只开启了开关，没有配置关键词搜索服务 | 配置 SearxNG/Brave/Tavily/Jina/自定义 JSON；如果只是读 URL，确保消息里有完整公开链接。 | +| `网络预检需检查` | 手机网络未验证、公网 DNS、VPN/代理/私人 DNS、应用联网权限、Base URL 域名或必要 API Key 有问题 | 先确认浏览器能打开公网网页；再检查 Wi-Fi 登录页、系统/安全中心是否禁止 MCA 使用 WLAN 或移动数据、私人 DNS/VPN/代理规则、搜索接口域名、协议路径和 Key。 | +| `鉴权失败` 或 401/403 | API Key 错误、权限不足、额度不可用 | 重新复制 Key，确认服务商账号和接口权限。 | +| 404 | Base URL 或接口路径不对 | 使用服务商文档里的搜索端点，不要把聊天模型端点填到搜索页。 | +| 429 | 服务限流 | 换自建/付费/备用搜索源，或稍后重试。 | +| 无来源 | 搜索服务返回空、公共实例屏蔽 JSON、相关性过滤后没有可用资料 | 换更明确的问题，增加官方关键词，或配置备用搜索源。 | +| 网页读取被阻止 | URL 指向 localhost、局域网、link-local 或保留地址 | 这是默认安全策略；公开版本不建议绕过。 | +| 搜索很慢 | 开启了正文抓取、多组研究查询、移动网络不稳定 | 降低结果数量，关闭正文抓取，或使用更快的搜索源。 | + +## 真实服务排障矩阵 + +最近检索卡片会把失败转换成 `处理建议`，复制诊断时也会带上这些建议。常见服务按下面口径排查： + +| 服务 | 404 时优先检查 | Key / 权限 | 备注 | +|---|---|---|---| +| SearxNG | 通常填实例根地址，MCA 会自动访问 `/search?format=json` | 多数实例不需要 Key | 公共实例可能关闭 JSON、限流或返回空结果，稳定使用建议自建。 | +| Brave Search | 常规搜索可填 `https://api.search.brave.com` 或 `https://api.search.brave.com/res/v1/web/search`；AI grounding/RAG 可用 `https://api.search.brave.com/res/v1/llm/context` | `X-Subscription-Token` | 官方根地址会自动补全到 Web Search。不要填写 Brave 首页、控制台、聊天模型接口或非搜索路径；Web Search 返回的 News/Discussions/FAQ/Videos 也会被解析为来源。 | +| Tavily Search | 可填 `https://api.tavily.com` 或 `https://api.tavily.com/search` | `Authorization: Bearer ` | 官方根地址会自动补全 `/search`；MCA 使用 POST JSON，正文抓取开启时会请求 advanced 搜索深度。 | +| Jina Search | 搜索服务推荐 `https://s.jina.ai` | `Authorization: Bearer ` | Reader 只用于网页正文增强，不要把 Reader 地址当作搜索地址。 | +| 自定义 JSON | 确认网关接收 `q/query/max_results`、自带查询参数，或 URL 模板如 `/search?q={query}&limit={max_results}` | 可选 Bearer Key | 返回结构建议包含 `results/items/data/hits/organic_results`，条目里至少有 `url/link/href` 和标题/摘要。 | + +如果诊断显示 `公开 JSON 自检源`，说明当前只是验证协议链路，不代表已经接入全网搜索。它能证明请求、JSON 解析、上下文注入和来源卡片可用，但正式使用仍应配置上表中的真实搜索服务或可信自建网关。 + +## 隐私说明 + +- 关键词搜索会发送到你配置的搜索服务。 +- 直接 URL 读取会访问该网页。 +- 本地模型不会自己联网，MCA 只把摘要注入当前一轮。 +- API Key 存在本机设置中，优先使用 Android Keystore 加密。 +- 最近检索诊断只保存在本机，可在联网检索设置页清空。 +- 短缓存只保留搜索结果摘要，不保存 API Key；直接 URL 读取不缓存。 diff --git a/docs/assets/demo/mca-demo.gif b/docs/assets/demo/mca-demo.gif new file mode 100644 index 0000000..007c703 Binary files

联网检索升级 + +- 新增联网检索入口和本轮检索状态，聊天页可以在输入框 `+` 菜单中切换联网检索。 +- 研究模式改为类似思考模式的二级胶囊选择，不再把复杂搜索配置塞进快捷菜单。 +- 支持完整 URL 直读、关键词搜索、来源卡片、检索追踪、质量评分和本地诊断记录。 +- 搜索源支持 `SearxNG`、`Brave Search`、`Tavily Search`、`Jina` 和自定义 JSON 网关。 +- 自定义 JSON 网关支持 URL 模板和常见字段解析，例如 `/search?q={query}&limit={max_results}`。 +- 设置页新增折叠区：使用说明、高级设置、备用搜索源、更多测试、最近检索，降低长页面压力。 +- README 和 `docs/WEB_SEARCH.md` 补齐“如何获取搜索源”，说明 Tavily、Brave、Jina、SearxNG、自定义 JSON 的获取方式和填写方式。 + +### 2. 本地 API 与第三方客户端兼容 + +- App 内新增 `API使用文档` 页面，说明 Base URL、API Key、`/v1/models`、`/v1/chat/completions` 和可信局域网使用边界。 +- 本地 API 继续使用 OpenAI-compatible 形态，便于同设备、局域网、浏览器或通用第三方客户端调用 MCA 已加载的本地聊天模型。 +- 强化第三方客户端兼容：保留客户端传入的 system/角色设定，不再因为重新载入模型导致第三方角色设定被 MCA 覆盖。 +- 强化多模态请求转发兼容：保留 inline image data URL，为后续视觉模型和多模态模型识图链路做准备。 +- 未加载模型时，API 会给出明确状态提示，避免第三方客户端误判为空回复。 + +### 3. 助手与角色卡能力 + +- 保留 MCA 本地助手体系，支持角色设定、默认模型偏好、生成参数和联网检索能力配置。 +- 优化常见角色卡导入兼容，把嵌套 `data` 字段里的 description、personality、scenario、first message、examples 合并为 MCA system prompt。 +- 角色卡导入后可继续由 MCA 本地存储管理，不依赖外部服务。 + +### 4. 模型管理和云端接入体验 + +- 云端推理引擎和图像生成引擎继续分开管理，避免聊天模型和生图模型混在一起。 +- 云端推理引擎接入从小弹窗改为完整页面，移动端可读性更好。 +- 图像生成引擎接入也改为完整页面，支持 `OpenAI Images`、`DashScope Image`、`Custom Image Path`。 +- 新增页面内测试结果区域，测试反馈不再被弹窗遮挡。 +- 输入表单不再预填指定模型名，用户自行填写模型、Base URL、API Key、图像路径和尺寸。 +- 云端模型页按钮布局保持紧凑，避免操作按钮遮挡模型名称。 +- 推荐页保留 ModelScope 优先口径，本地生图继续标注为实验功能。 + +### 5. UI 和交互打磨 + +- 保留 MCA 原有清爽、低对比、圆润的移动端设计语言，不重构聊天主界面。 +- 历史 / 工作区首页保持轻量结构：默认突出图片和最近聊天，不把模型管理放入历史页。 +- 右上角菜单继续承载系统设置、模型管理、本地 API、智能调参等入口。 +- 除历史抽屉外，二级页面统一为从右往左进入、返回时向右退出，修正部分页面方向不一致的问题。 +- 菜单项去掉冗余小字说明，页面内再展示必要说明，移动端更干净。 +- 图像页、本地 API、联网检索、模型管理等关键页完成真机可见性检查。 + +## 兼容矩阵 + +| 能力 | 当前状态 | 说明 | +|---|---|---| +| 本地聊天 | 支持 | GGUF / llama.cpp CPU 后端，适合小到中等参数量量化模型。 | +| 云端聊天 | 支持 | OpenAI-compatible 和 Anthropic Messages。具体可用性取决于服务商 Base URL、模型名和协议路径。 | +| 本地 API | 支持 alpha | OpenAI-compatible，本机或可信局域网使用。需要先加载本地聊天模型。 | +| 云端生图 | 支持 alpha | OpenAI Images、DashScope Image、自定义图像路径。 | +| 本地生图 | 实验功能 | 需要完整引擎包：diffusion 主模型 + VAE/AE + 文本编码器/LLM。CPU 生图不承诺稳定高速。 | +| 联网检索 | 支持 alpha | 直读公开 URL；关键词搜索需要用户配置搜索源。 | +| 本地识图 | 预留链路 | 需要兼容的多模态 GGUF 模型和 projector；纯文本 GGUF 不能识图。 | +| 云端识图 |

+- release APK 可安装，版本显示为 `0.2.0-alpha` / `versionCode 4`。 +- 首次启动正常，未出现闪退。 +- 历史 / 工作区首页正常，只展示图片入口和最近聊天。 +- 右上角菜单正常，入口包括助手与角色、模型管理、智能调参、本地 API、系统设置等。 +- 系统设置 -> 联网检索正常，`使用说明` 可展开，`如何获取搜索源` 内容可见。 +- 本地 API 页面正常，`API使用文档` 可打开，Base URL、API Key、模型列表和聊天补全说明可见。 +- 模型管理页正常，本地、云端、推荐等 Tab 可切换。 +- 云端推理引擎接入页正常，包含显示名称、模型名、协议、Base URL、API Key、测试和保存。 +- 图像生成引擎接入页正常，包含 OpenAI Images、DashScope Image、Custom Image Path、图像路径和尺寸。 +- 最终 logcat 未发现 `FATAL EXCEPTION`、`ANR`、`RuntimeException` 或 MCA 相关崩溃。 + +构建验证： + +- `:app:assembleRelease` 通过。 +- 早前调试构建验证：`:feature:settings:compileDebugKotlin :app:assembleDebug` 通过。 + +## 已知限制 + +- 本地 API 的真实对话需要先加载本地聊天模型；本轮 release 验收没有加载大模型做长对话压测。 +- 云端模型兼容性依赖服务商协议实现。Anthropic Messages、OpenAI-compatible、DashScope Image 等都需要用户填写正确 Base URL、模型名、Key 和路径。 +- 联网检索关键词搜索必须配置搜索源。公开 JSON 自检源只能验证协议链路，不能当正式搜索服务。 +- 本地生图仍是实验功能，CPU 生图速度和稳定性高度依赖设备、模型包、尺寸、步数和散热。 +- 本地识图不等于普通 GGUF 识图，必须使用多模态模型和匹配 projector。 +- APK 不包含模型权重、云端账号或 API Key。 + +## 发布建议 + +- GitHub Release 标记为 pre-release / alpha。 +- Release 附件上传 release APK 和 SHA-256 校验值，不把 APK 提交进源码仓库。 +- Release 标题建议：`MCA v0.2.0-alpha - Web Search, Local API Docs, Cloud Engine Pages` +- 对外宣传主推：本地聊天、云端 / 本地生图能力已接入、本地 API、隐私边界清晰。 +- 对本地生图继续使用“实验功能”口径，不宣传为稳定高速主功能。 +- 发布前再次确认 README、截图、release notes 和源码中没有账号 Key、私有测试接口、本机路径或个人隐私信息。 diff --git a/feature/agent/build.gradle.kts b/feature/agent/build.gradle.kts new file mode 100644
