Legacy compatibility alias for the code-testing skill. Do not self-activate for user requests and do not treat this name as a custom agent. When invoked explicitly by older instructions, load code-testing and follow it instead.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Legacy Code Testing Alias This skill preserves explicit calls that still use the former `code-testing-agent` name. The public custom agent is `test-engineer`; the model-facing implicit skill is `code-testing`. 1. Invoke the `code-testing` skill with the original user request. 2. Follow that skill's workflow without adding another interpretation layer.
Read the whole file at its exact version.
How to install
mdr add dotnet/skills/code-testing-agent@sha256:76f48e19182a147cThe line at the top of this page pins the label git:20261008.a51399b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
