Implement the run command executor that makes REPL `run(...)` behave like a real workflow `run:` step by reusing the runner's existing infrastructure. Key design choices: - Shell resolution mirrors ScriptHandler: job defaults → explicit shell from DSL → platform default (bash→sh on Unix, pwsh→powershell on Windows) - Script fixup via ScriptHandlerHelpers.FixUpScriptContents() adds the same error-handling preamble as a real step - Environment is built from ExecutionContext.ExpressionValues[`env`] plus runtime context variables (GITHUB_*, RUNNER_*, etc.), with DSL-provided env overrides applied last - Working directory defaults to $GITHUB_WORKSPACE - Output is streamed in real time via DAP output events with secrets masked before emission through HostContext.SecretMasker - Only the exit code is returned in the evaluate response (avoiding the prototype's double-output bug) - Temp script files are cleaned up after execution Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
GitHub Actions Runner
The runner is the application that runs a job from a GitHub Actions workflow. It is used by GitHub Actions in the hosted virtual environments, or you can self-host the runner in your own environment.

Note
Thank you for your interest in this GitHub repo, however, right now we are not taking contributions.
We continue to focus our resources on strategic areas that help our customers be successful while making developers' lives easier. While GitHub Actions remains a key part of this vision, we are allocating resources towards other areas of Actions and are not taking contributions to this repository at this time. The GitHub public roadmap is the best place to follow along for any updates on features we’re working on and what stage they’re in.
We are taking the following steps to better direct requests related to GitHub Actions, including:
-
We will be directing questions and support requests to our Community Discussions area
-
High Priority bugs can be reported through Community Discussions or you can report these to our support team https://support.github.com/contact/bug-report.
-
Security Issues should be handled as per our SECURITY.md
We will still provide security updates for this project and fix major breaking changes during this time.
You are welcome to still raise bugs in this repo.
