Individual skill
code-testing
ALWAYS USE for test work that requires changes: write, add, generate, repair, or strengthen tests for existing code in xUnit, MSTest, NUnit, pytest, Vitest/Jest, Go, or another framework. Includes regression cases, failing or flaky tests, coverage-driven additions, and audit-then-fix requests. Focused work stays direct; broad or multi-stage work invokes test-engineer. DO NOT USE for only running tests, analysis-only audits, framework/platform migrations, a test blocked on a missing production seam (testability-obstacle), or MSTest API/configuration corrections that do not design new cases (writing-mstest-tests). Within an active test-engineer pipeline, reuse supplied guidance and do not re-enter this skill.

# Code Testing Skill
The reliable implicit entry point for generating, repairing, and strengthening
tests. It handles focused work directly and invokes the public `test-engineer`
agent for broad or multi-stage requests.
## Non-negotiable execution contract
**Check pipeline ownership first.** If the active agent is
`test-engineer` (including a plugin-qualified name such as
`dotnet-test:test-engineer`), or the caller assigned you a phase of
that pipeline, do not delegate to another generator. Continue the assigned
work inline. This guard takes precedence over every broad-scope delegation
instruction below, even if this skill was loaded automatically.
