add-dotnet-aot-command

Add, enable, or review a dotnet CLI command or feature in the Native AOT CLI (src/Cli/dotnet-aot) and prove its compatibility. USE FOR: migrating a command or option to AOT, reviewing an AOT migration PR, defining conservative eligibility and managed fallback, changing AotSourceFiles.props or AotDependencies.props, validating AOT/managed parity, NativeAOT-publishing tests, checking binary-size impact, or using the dn harness and separated SDK layout. DO NOT USE FOR: resolving IL trim/AOT analyzer warnings alone (use dotnet-aot-compat), running dotnet.Tests incrementally (use incremental-test), or pure managed CLI work.

run-tests

Select and run .NET SDK tests through the repository's diagnostic-preserving test entry point. REQUIRED whenever an agent will select, run, or rerun local dotnet/sdk tests, including a project, class, method, targeted test, focused test, smallest relevant test, or completed-change validation. NEVER invoke when the user says not to run tests yet.

2026-11-02

code-review

Review code changes in dotnet/sdk for problems — either a GitHub pull request or local changes in your branch before a PR exists. Use when asked to review a PR, review local or uncommitted changes, do a code review, check a PR or branch for issues, or review pull request changes. Focuses only on identifying problems — not style nits or praise.
