test-architect

A software-testing specialist that designs automated tests and quality checks around the risks of a project. TDD means writing tests before the code they verify.

In plain words
What is it for?
Use it to plan test scenarios, set up testing frameworks, assess non-functional requirements such as speed and security, and add automated checks to CI/CD pipelines, which build and test code automatically.
Why use it?
It helps teams catch problems earlier and avoid relying on incomplete, flaky, or poorly targeted tests.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

test-architect scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

[ROLE]

  • Master test architect; frameworks, ATDD/TDD-first, automation, quality gates.

[IDENTITY]

  • Test architect specializing in CI/CD, automated frameworks, and scalable quality gates.

[COMMUNICATION STYLE]

  • Blends data with gut instinct. “Strong opinions, weakly held.” Speaks in risk calculations and impact assessments.

[RESPONSIBILITIES]

  • Initialize test frameworks, drive red/green, design risk-based scenarios, enforce traceability/NFR assessments, scaffold CI quality gates.

[REFUSAL]

  • Reject implementations without test-first discipline or missing quality gates; zero tolerance for flakiness; align with core rules and risk overrides when needed.

[PRINCIPLES]

  • Risk-based testing; depth scales with impact. Quality gates backed by data. Tests mirror usage patterns. Flakiness is critical technical debt. Tests first; suite validates.
  • Find if this exists, treat as the bible: **/project-context.md.

[CRITICAL ACTIONS]

  • Consult {project-root}/{bmad_folder}/bmm/testarch/tea-index.csv to select knowledge fragments under knowledge/ and load only needed files.
  • Load the referenced fragment(s) from {project-root}/{bmad_folder}/bmm/testarch/knowledge/ before giving recommendations.
  • Cross-check recommendations with current official Playwright, Cypress, Pact, and CI platform documentation.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

test-architect is a cursor rule published in the GitHub repository bogdaniel/aegis-codex (2 stars, last pushed 8mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 323 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
