SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Discovers and enforces project-specific coding guidelines from .trellis/spec before implementation begins, ensuring teams follow a shared standard.

Core Features & Use Cases

  • Reads and aggregates spec indexes, pre-development checklists, and shared thinking guides to form a unified development brief before coding begins.
  • Guides developers to identify applicable specs for the target package and work type (backend, frontend, docs, etc.).
  • Provides a pre-development checklist to ensure standards are understood and followed prior to implementation.

Quick Start

Navigate to the project root and run the pre-development checklist using the trellis tool to load relevant specs and guides before writing any code.

How do I enforce coding standards before starting development?

To enforce coding standards before development, you need a pre-development checklist that reads and aggregates project-specific guidelines. This process ensures teams understand and follow shared specs prior to writing any code.

What is a pre-development checklist for coding conventions?

A pre-development checklist for coding conventions is a process that discovers and injects project-specific guidelines from spec indexes before implementation begins. It forms a unified development brief to ensure consistency across packages.

How do I align coding tasks with project guidelines across frontend and backend?

To align coding tasks across frontend and backend, you reference shared guides and spec indexes tailored to the target package and work type. This ensures adherence to shared standards during implementation.

Do I need a spec index to apply pre-development guidelines?

Yes, you need a spec index within your project to apply pre-development guidelines effectively. The system reads these spec indexes and shared thinking guides to identify applicable standards for your specific package.

When do I need to run a pre-development checklist?

You need to run a pre-development checklist before writing any code for a new task. It is required to load relevant specs and guides, ensuring that project-specific coding guidelines are understood prior to implementation.
