Analyze an existing test suite in any supported language and apply a standardized set of trait tags to each test method, giving teams visibility into their test distribution (positive vs. negative, critical-path coverage, smoke tests, etc.).
Language-specific guidance
Call the
test-analysis-extensions
skill to discover available extension files, then read the file matching the target codebase. The extension file documents framework-specific tag attributes and a "tag-support capability" (auto-edit, report-only, or convention-based) that drives whether this skill modifies source files or only emits a report.
When to Use
Auditing a test project to understand the mix of test types
Adding trait attributes to untagged tests
Generating a summary report of trait distribution across a test suite
Reviewing whether critical paths have sufficient coverage
When Not to Use
Writing new tests from scratch (use
code-testing-agent
for any language, or
writing-mstest-tests
for MSTest)
Running or filtering tests (use
run-tests
for .NET; equivalent native runners elsewhere)
Migrating between test frameworks
