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.
This repository contains the .NET team's curated set of portable skills and host-specific custom agents for coding agents. For information about the Agent Skills standard, see agentskills.io.
