Workflow Routing (SYSTEM PROMPT)

Set up testing: "set up testing", "init testing", "bootstrap test infra" -> READ: ${PAI_DIR}/skills/tdd-qa/workflows/init-project.md -> EXECUTE: Copy templates, create specs/ dir, configure bunfig.toml

Define test scenarios: "write scenarios for X", "define test cases", "spec out the feature" -> READ: ${PAI_DIR}/skills/tdd-qa/workflows/write-scenarios.md -> EXECUTE: Create Given/When/Then specs from requirements

Run a TDD cycle: "run TDD on X", "red green refactor", "TDD this feature" -> READ: ${PAI_DIR}/skills/tdd-qa/workflows/tdd-cycle.md -> EXECUTE: RED→GREEN→VERIFY loop with 2-retry escalation

Run test pyramid: "run the pyramid", "run all test layers", "full test suite" -> READ: ${PAI_DIR}/skills/tdd-qa/workflows/run-pyramid.md -> EXECUTE: Static→Unit→Integration→E2E in sequence

Check for regressions: "backtest", "check regressions", "compare test results", "quality gate" -> READ: ${PAI_DIR}/skills/tdd-qa/workflows/backtest.md -> EXECUTE: Compare JUnit XML baselines, check coverage delta, enforce gates

E2E browser verification: "verify E2E", "browser test", "e2e scenarios", "smoke test the UI" -> READ: ${PAI_DIR}/skills/tdd-qa/workflows/e2e-verify.md -> EXECUTE: Run scenarios via devtools-mcp, auto-draft .spec.ts

Mutation testing: "run mutation tests", "check mutation score", "how good are my tests" -> READ: ${PAI_DIR}/skills/tdd-qa/workflows/mutation-check.md -> EXECUTE: Run StrykerJS, report mutation score (advisory)

Philosophy/patterns/mocking: Not in this skill — see CORE testing-guide.md, mocking-guidelines.md, interface-design.md.

Boundary: CORE/testing-guide.md = philosophy (always loaded). This skill = executable blueprints (on-demand fork context).

Usage Modes

ModeFlow
New featurewrite-scenarios -> tdd-cycle -> backtest
Bug fixtriage-issue -> fix -> backtest
Confidencebacktest or run-pyramid
New projectinit-project (once)

Workflow steps are typed deterministic or agentic (Stripe Minions pattern). See references/blueprint-pattern.md.

Bombadil (v0.3.2) is experimental — invoke explicitly, not routed by default. → READ: workflows/explore-bombadil.md when user asks for Bombadil exploration.

Lifecycle Completion

Minimum Complete Cycle

  1. write-scenarios — Given/When/Then specs (mandatory human review gate at step 4)
  2. tdd-cycle — RED→GREEN→REFACTOR for each scenario
  3. backtest — regression check, baseline update

Complete when backtest passes with zero regressions and baseline updated.

Optional Extensions

ExtensionWhen to suggestPrerequisite
mutation-checkAfter backtest passes, for critical code pathsStrykerJS installed
e2e-verifyWhen feature has a browser UIdevtools-mcp available
run-pyramidBefore merging a PR, as final confidence checkTests exist at multiple layers

System-Level "Done"

A feature is fully tested when:

  • All quality gates pass (zero regressions, coverage not decreased)
  • Baseline updated
  • JM has reviewed and approved scenarios

Do not proactively run optional extensions unless JM asks or the feature touches critical code paths.

Composing Workflows

Canonical Sequences

Request typeSequenceSkippable steps
New featurewrite-scenarios → tdd-cycle → backtestwrite-scenarios skippable if JM provides inline requirements
Bug fixtdd-cycle (RED: failing test for bug) → backtestwrite-scenarios usually skipped for single bugs
Confidence checkbacktest or run-pyramidBoth standalone
Refactoringbacktest (before) → refactor → backtest (after)No TDD cycle — existing tests are the safety net

Ambiguous Requests

If a request spans multiple workflows, ask which workflow to start with rather than guessing. Example: "add auth and make sure nothing breaks" could mean write-scenarios + tdd-cycle + backtest, or just a confidence backtest on existing code.
