What it does
Flutter Debug Runtime is an agent skill from bladeofgod/flutter-ai-harness. 适用：在 App Operator 或 Marionette 验证前，为 Android/iOS 构建、安装并启动 Flutter Debug App，获取 VM Service URI。不适用：Release 构建、签名配置、系统权限自动化、账号登录或测试数据准备。触发词：flutter run、Debug App、设备安装、VM Service URI、App Operator 前置环境。
Its SKILL.md is about 270 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Mobile, covering Cross-platform mobile apps. It works with Flutter, Android and iOS. The repository describes itself as: An AI-native engineering harness for production Flutter and hybrid mobile app repositories. The licence is MIT.
When your agent uses it
- Tasks that involve Cross-platform mobile apps
Example prompts
- “/flutter-debug-runtime”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- 读取 Spec，并只处理用户在 /execute-ui-spec 中明确选择的当前平台；不得自动扩展到 Spec 的其他声明平台。
- 运行 bash scripts/flutter-tool.sh devices，选择用户指定设备；存在多个候选且用户未指定时请求选择。
- 依赖发生变化时先运行 bash scripts/dart-tool.sh pub get。
- 使用以下入口构建、安装并保持 Debug App 运行
- 从输出中取得 ws://.../ws VM Service URI，只在当前调用中交给 Operator，不写入仓库产物。
- 确认 App 启动且 Marionette Binding 可连接后，将目标平台、非敏感 OS 版本、设备类型和 VM Service URI 仅在当前调用中交接给 Operator。
What it can do on your machine
Read from SKILL.md and the folder at commit 9f1a1ca. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
bash
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Flutter Debug Runtime loads about 274 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 57 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Flutter Debug Runtime
为运行态 UI 验证准备 App；完成交接后由 app-operator 专注执行 Spec。
流程
读取 Spec，并只处理用户在
/execute-ui-spec中明确选择的当前平台；不得自动扩展到 Spec 的其他声明平台。运行
bash scripts/flutter-tool.sh devices，选择用户指定设备；存在多个候选且用户未指定时请求选择。依赖发生变化时先运行
bash scripts/dart-tool.sh pub get。使用以下入口构建、安装并保持 Debug App 运行：
bash TOOL_WORKDIR=app/apps/demo bash scripts/flutter-tool.sh run --debug -d <device-id>从输出中取得
ws://.../wsVM Service URI，只在当前调用中交给 Operator，不写入仓库产物。确认 App 启动且 Marionette Binding 可连接后，将目标平台、非敏感 OS 版本、设备类型和 VM Service URI 仅在当前调用中交接给 Operator。
不得修改签名、Development Team、应用标识或发布配置。设备不可用、系统权限弹窗阻塞、账号/测试数据缺失或平台工具链需要人工处理时，准确说明阻塞并请求介入，不用伪造状态或产品行为绕过。
