+description: Run DeviceLab tests for Flutter PRs using LUCI's `led` CLI tool. Use when asked to run, launch, try, or deflake a post-submit or devicelab test against a PR using `led`.
+---
+
+<!--
+Host assumptions:
+    Installed and on path:
+        * led (from depot_tools)
+        * git
+        * gh
+    Had authentication setup:

+        * gcert / glogin (SSO auth required for recipes repository git operations)

+# Running DeviceLab Tests with `led`
+
+This skill guides running post-submit and DeviceLab tests for pull requests (PRs) using LUCI's `led` CLI tool. For additional context, see [docs/infra/Running-Devicelab-Tests-For-PR.md](../../../docs/infra/Running-Devicelab-Tests-For-PR.md).
+
+## Prerequisites
+
+1. **`led` tool**: Must be installed (via `depot_tools`) and available in your `PATH`. Verify via `led auth-info`.
+2. **SSO authentication**: Verify valid SSO / LOAS credentials via `gcertstatus` or `glogin status`. If expired, instruct the user to run `glogin` or `gcert`.
+3. **`recipes` repository** (when including `led edit-recipe-bundle`): If testing local recipe changes or recipe-only PRs, commands containing `led edit-recipe-bundle` must be executed from the root of a local checkout of the Flutter [`recipes`](https://flutter.googlesource.com/recipes) repository (`git clone https://flutter.googlesource.com/recipes`).
+
+## Workflow
+
+### 1. Gather Inputs based on PR Type
+
+Collect the following required arguments:
+* **`PR_NUMBER`**: The pull request number (e.g., `123456`).
+* **`PRESUBMIT_TEST`**: The exact name of the LUCI staging builder to run (e.g., `Windows_mokey hot_mode_dev_cycle_win__benchmark` or `Mac_ios microbenchmarks_ios`).
+
+### 2. Execute `led` Pipeline
+
+If you are using `led edit-recipe-bundle` to test local recipe modifications, navigate to the root of your local `recipes` repository checkout (`$CWD` is packaged by `led edit-recipe-bundle`). If only testing without recipe edits, `led edit-recipe-bundle` can either be run from a `recipes` checkout or omitted.
+
+Run the command pipeline corresponding to the PR type:
+
+#### Command
+
+```bash
+led get-builder 'luci.flutter.staging:PRESUBMIT_TEST' \
+  | led edit -pa git_ref='refs/pull/PR_NUMBER/head' \
+  | led edit -pa git_url='https://github.com/flutter/flutter' \
+  | led edit-recipe-bundle \
+  | led launch
+```
+
+### 3. Report Launched Task Details
+
+`led launch` outputs details about the launched build, including Swarming / LUCI task links. Provide the resulting URL to the user so they can track execution progress and examine logs.
+
+## Example
+
+- **User Prompt**: "Run the devicelab test `Windows_mokey hot_mode_dev_cycle_win__benchmark` for framework PR 12345 with led."
+- **Action**: Run the `led` command (navigate to local `recipes/` directory if using `led edit-recipe-bundle` for local recipe edits):
+  ```bash
+  led get-builder 'luci.flutter.staging:Windows_mokey hot_mode_dev_cycle_win__benchmark' \
+    | led edit -pa git_ref='refs/pull/12345/head' \
+    | led edit -pa git_url='https://github.com/flutter/flutter' \
+    | led edit-recipe-bundle \
+    | led launch
+  ```

 - **Search for counter-examples**: Identify scenarios or edge cases that the proposed code does not handle. If a counter-example is found, propose a test case to demonstrate the gap.
 - **Suggest simplification and refactoring**: Assess whether the code can be made simpler or refactored to enhance readability and maintainability.
 
+### What Not to Report
+
+- **Do not report syntax errors**: Leave the detection of syntax errors to the analyzer. The review agent should focus on higher-level concerns such as logic, design, and maintainability rather than issues that automated tooling already catches.
+
 ## General Philosophy
 
 - **Optimize for readability**: Code is read more often than it is written.
