Feature

"Write failing Behat scenarios for: [feature]. Suite: api. Run vendor/bin/behat --suite=api, confirm all scenarios fail."

Task B — PHPUnit (unit + feature layer):

"Write failing PHPUnit tests for: [feature]. Run php artisan test (Laravel) or vendor/bin/phpunit (Symfony/agnostic), confirm all tests fail."

Do NOT proceed to Step 3 until:

• All Behat scenarios are written and confirmed failing
• All PHPUnit tests are written and confirmed failing

Report: "X Behat scenarios written (all failing). Y PHPUnit tests written (all failing)."

3. Implement (GREEN)

Write minimal code to pass tests. Implementation is complete when BOTH pass:

• vendor/bin/behat --suite=api exits 0
• php artisan test (Laravel) or vendor/bin/phpunit (Symfony/agnostic) exits 0

4. Refactor

• Split methods > 20 lines
• Extract repeated logic
• Full type coverage
• Remove dead code

5. Review

Delegate to code-reviewer agent:

"Review all changed files against CLAUDE.md and org conventions."

Fix any blocking issues.

6. Commit

• Branch: feature/<short-description>
• Message: imperative mood, max 72 chars, body explains why
• Stage only related files

7. Report

Summarize: files changed, tests written, pass rate, review result, branch name.
