This skill should be used when a developer is ready to implement a GitHub Task issue and needs to read the full spec hierarchy (Task + Feature + Epic), explore the codebase, produce a concrete Technical Approach with real file paths, and drive TDD implementation against Gherkin scenarios. Triggers on phrases like "implement task
Implements SDD plan tasks following specs and design, marking progress in tasks.md as it goes. Trigger: /sdd-apply <change-name>, implement change, apply SDD tasks, write code for change.
Fix a bug with systematic debugging, TDD, and PR workflow
Execute implementation plans with checkpoint validation, progress tracking, and quality gates. Use for task implementation, plan execution, progress tracking. Skip if no plan exists.
Test-driven development with Kent Beck's canonical 5-step workflow: Test List, Write Test, Make Pass, Refactor, Repeat. Strict vertical-slice cycles with automatic project detection. Use when the user asks to "write tests first", "use TDD", "red-green-refactor", "test-driven development", "build a feature with TDD", "fix a bug with TDD", wants test-first development for any language or framework, or mentions "tracer bullet" or "vertical slice".
Implements transactional emails with Action Mailer and TDD. Use when creating email templates, notification emails, password resets, email previews, or when user mentions mailer, email, notifications, or transactional emails.
Create work-order with minimal context for isolated subagent execution, optionally linked to GitHub issue
Use when writing tests, adding coverage, implementing business logic, or building features with TDD. Enforces output-based testing of pure functions only - never test imperative shell directly.
Use when writing new functions, adding features, fixing bugs, or refactoring by applying TDD principles - write failing tests before implementation code, make them pass, then refactor.
Refactor code after tests pass. The "Refactor" phase of Red-Green-Refactor.
Enforce Test-Driven Development (TDD) workflow for all code changes. Apply PROACTIVELY by default using Red-Green-Refactor cycles for features, bug fixes, and refactoring.
Full feature pipeline — pre-flight checks, TDD cycle, scope guard, quality commit. Combines pre-flight + tdd + scope-check + quality-commit into one flow. Use when implementing a feature, adding an endpoint, or building any non-trivial code change.
