SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides a structured, TDD-driven implementation phase that ensures feature code aligns with pre-defined specifications after analysis.

Core Features & Use Cases

  • TDD-driven implementation: Enforces tests before coding, ensuring features meet acceptance criteria.
  • Quality gates enforcement: Integrates typecheck, lint, tests, and PRD constraints before marking tasks complete.
  • PRD-driven workflow guidance: Guides the transition from spec to coding with traceable progress and governance.

Quick Start

Run the Relentless implementation phase for a given feature after analysis, plan, and tasks are prepared. For example: relentless run --feature my-feature --phase implement

FAQPage Schema
How do I automate feature implementation with TDD and PRD alignment?

Automated feature implementation uses a structured, test-driven workflow to enforce tests before coding and align final code with PRD requirements. It runs through plan, tasks, convert, and analyze stages to ensure deliverables satisfy quality gates.

What quality gates are enforced during test-driven implementation?

Test-driven implementation enforces quality gates by integrating typecheck, lint, and tests before marking tasks complete. It continuously runs validations to guarantee code changes meet pre-defined acceptance criteria and PRD constraints.

How do I run the implementation phase after analysis passes?

To run the implementation phase after analysis passes, execute the implementation command with the target feature and phase flags. This initiates the automated workflow covering plan, tasks, convert, and analyze stages for that specific feature.

Do I need a PRD before starting the TDD implementation workflow?

Yes, a PRD is required before starting the TDD implementation workflow. The process is PRD-driven, meaning it guides the transition from specification to coding with traceable progress and governance based on your pre-defined requirements.

What is the best way to ensure code meets acceptance criteria before completion?

The best way to ensure code meets acceptance criteria is using a disciplined TDD cycle that enforces tests before coding. This approach applies continuous quality validations and checks PRD constraints before marking any implementation task complete.

Why does implementation fail if prerequisite checks do not pass?

Implementation fails when prerequisite checks do not pass because the workflow enforces strict quality gates and TDD cycles. This prevents incomplete or non-compliant code from progressing to subsequent stages and ensures all artifacts align with PRD requirements.
