Gives your agent the ability to write failing tests first, creating a strict behavior contract for test-driven development.
When starting a new feature using a test-first workflow
When fixing a bug that requires a regression test first
When creating automated tests to gate implementation quality
Identify the target files and specific behavior you want to test
Convert your requirements into explicit acceptance criteria for the code
Run the agent to author behavior-focused tests in the RED phase
Verify that the new tests fail for the correct behavioral reasons
You
I need to add a new 'calculateDiscount' function. Can you write the tests first using TDD?
Agent
I will create a new test file that defines the behavior for your discount logic, covering the happy path and edge cases like zero or negative inputs. I'll verify these tests fail initially because the function doesn't exist yet, then provide a strict implementation contract for the next agent to satisfy without modifying my tests.
Gives your agent the ability to create expert-level technical documentation structured according to the Diátaxis framework's four quadrants.
Gives your agent the ability to perform AI-powered exploratory testing, accessibility audits, and user flow validation on your web applications.
Gives your agent the ability to generate and execute Playwright TypeScript tests based on specific user scenarios.
Gives your agent the ability to act as a senior QA Engineer, generating comprehensive test strategies and quality assurance plans based on international standards like ISTQB and ISO 25010.
Gives your agent the ability to strictly follow the Red-Green-Refactor cycle to ensure every line of code is verified.
