Quality Engineer
by Matthew King
A risk-first QA agent that hunts bugs via personas, extracts BDD requirements, and drives TDD fixes.
- Map technical debt and quality risks to business impact priorities.
- Identify edge-case bugs using specialized user-behavior personas.
- Reverse-engineer a legacy codebase into BDD requirements and a traceability matrix.

Sample input
Identify the most risky areas in this repo and suggest which personas I should use to hunt for bugs.
Sample output
| Area | Risk | Priority | Persona | Rationale | |---|---|---|---|---| | /api/payments | Critical | High | The Cynic | High complexity, lacks idempotency checks. | | /auth/session | High | Med | The Wanderer | Potential leaks in middleware session state. |
Hunt suggested for /api/payments first.

About This Skill
Professional Quality Engineering for Your Repository
The Quality Engineer skill transforms your AI agent into a proactive QA partner that goes beyond simple bug catching. It implements a structured loop to understand, assess, cover, find, fix, and verify your codebase. Unlike generic AI prompting, this skill uses persona-based testing and a risk-first methodology to identify where failures would cause the most business impact.
What it does
- Risk Analysis: Generates a repo-specific risk map, identifying high-priority areas that lack sufficient coverage.
- Persona-Based Bug Hunting: Employs specialized user personas to "stress test" your application through different behavioral lenses.
- Requirements Extraction: Reverse-engineers your code and existing tests into a BDD-style requirements pack and traceability matrix.
- Test Generation: Automatically scaffolds unit, integration, and E2E (Playwright) tests in your project's native style.
- TDD Loop: Drives a strict Red-Green-Refactor cycle to fix bugs or implement features with 100% test confidence.
Why use this skill?
Standard AI agents often write superficial tests or hallucinate requirements. This skill enforces a disciplined engineering workflow, ensuring that every bug report is backed by code evidence and every new test addresses a documented risk.
Use Cases
- Map technical debt and quality risks to business impact priorities.
- Identify edge-case bugs using specialized user-behavior personas.
- Reverse-engineer a legacy codebase into BDD requirements and a traceability matrix.
- Automate the Red-Green-Refactor cycle for TDD-based bug fixing.
- Audit and expand Playwright E2E suites based on discovered persona gaps.
