Write the test first. Watch it fail. Write minimal code to pass.

This skill guides you through creating custom external web service APIs for Moodle LMS, following Moodle's external API framework and coding standards.

Dispatch fresh subagents per task with two-stage review for fast, high-quality implementation execution. \n \n Assigns one subagent per task with spec compliance review first, then code quality review, ensuring both correctness and code standards \n Keeps execution in the current session with automatic review loops that re-run when issues are found, eliminating context switches \n Subagents ask clarifying questions before implementation begins and self-review their work before handoff to reviewe

Write failing tests first, then minimal code to pass, then refactor while keeping tests green. \n \n Follows the red-green-refactor cycle: write one failing test, verify it fails correctly, implement minimal code to pass, verify all tests pass, then refactor safely \n Requires watching each test fail before writing implementation code; tests that pass immediately prove nothing about correctness \n Applies to all new features, bug fixes, refactoring, and behavior changes; code written before test
