Run the TechEmpower ASP.NET Core benchmarks against a locally-built dotnet/runtime, either locally with an SDK overlay or on external infrastructure using Crank, to validate the end-to-end impact of a runtime change (e.g. sockets, io_uring, GC, JIT) under…
Generate breaking change documentation for merged dotnet/runtime PRs. USE FOR: creating breaking change docs, "document this breaking change", "write breaking change issue for PR #NNNNN", processing PRs labeled needs-breaking-change-doc-created. DO NOT USE…
Build and test dotnet/runtime locally. Covers the mandatory baseline build, per-component build and test commands, Windows/PowerShell equivalents, running individual tests, and troubleshooting. USE FOR: any build or test invocation in this repo, and before…
Analyze a concrete CI failure and draft a Known Build Error issue or update in dotnet/runtime. Publish only with explicit user authorization or scoped authorization from an executing workflow's documented publication contract. Use when a failure is…
Triage a dotnet/runtime GitHub issue with duplicate search, label check, reproduction, and ecosystem research, then recommend KEEP/CLOSE/NEEDS INFO. Use when asked to triage, evaluate, assess, or check a specific GitHub issue. Also use when asked "is this a…
Extract a standalone JIT regression test case from a given GitHub issue and save it under a JIT regression runner folder. USE FOR: creating JIT regression tests, extracting repro code from dotnet/runtime issues, "write a test for this JIT bug", "create a…
Generate and run ad hoc BenchmarkDotNet microbenchmarks to validate the performance impact of a code change. Use this when asked to benchmark, profile, or validate the performance impact of a code change in dotnet/runtime at the method/API level. For…

Analyze a dotnet/runtime PR's CI failures, skip failures already known to Build Analysis, find matching Known Build Errors, and create or draft new KBEs for the remaining failures. Supports dry-run output to local markdown files instead of creating GitHub…
Guidance for writing and reviewing SIMD / hardware-intrinsics code in dotnet/runtime. USE FOR: vectorizing a scalar algorithm, writing or reviewing code that uses Vector128/Vector256/Vector512, Vector<T>, or the platform intrinsics in…
Monitors .NET runtime CI test pipelines on Azure DevOps. Use this skill when asked to monitor CI pipeline test results, triage CI test failures across ADO pipelines, or generate CI test monitoring reports.
Review code changes in dotnet/runtime for correctness, performance, and consistency with project conventions. Use when reviewing PRs or code changes.
Narrowly quarantine failing dotnet/runtime tests while preserving unaffected coverage. USE FOR: disable a failing test, skip a test against an issue, add ActiveIssue, quarantine a flaky configuration, split failing theory data, suppress a runtime-test…
Resolve a CoreCLR runtime test from a generated .cmd or .sh wrapper path for the standalone-test-repro workflow. Use when the requested test is identified by a CI or Helix wrapper path, with or without a named test scenario. Continue with the parent…
Resolve a CoreCLR runtime test from a fully qualified method name for the standalone-test-repro workflow. Use for xUnit display names and methods in merged or multi-test assemblies, with or without a named test scenario. Continue with the parent…
Generate a standalone console application under artifacts/tmp from a managed test under src/tests so it can be run directly with corerun. USE FOR: "create a standalone repro for this runtime test", converting a CoreCLR test wrapper path such as…
Generate a CoreRun-compatible .env file for a named CoreCLR test scenario defined by src/tests/Common/testenvironment.proj. Optionally merge the effective common and target-specific environment items from a specific src/tests project. USE FOR: "create an env…
