SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Carta-builder converts ambiguous design directions into structured, user-validated planning artifacts by investigating a Carta .carta/ workspace and the associated MCP Carta document, then producing only todo-tasks/ for an implementer.

Core Features & Use Cases

  • Workspace-driven design investigation: Uses .carta/ structure plus Carta’s document/model summaries to understand constructs and schemas without reading source code.
  • Tradeoff-focused design discussion: Helps users choose between options and clarifies scope, constraints, and decision rationale before anything is implemented.
  • Actionable planning outputs: Creates correctly formatted todo-tasks/ (including optional epic files) that include motivation, design decisions, and a required verifiability section.

Quick Start

Ask the AI to evaluate the current Carta workspace and propose a concrete design plan, then create the needed todo-tasks/ based on your chosen direction.

FAQPage Schema
How do I turn Carta workspace explorations into implementer-ready planning artifacts?

You can convert design explorations into deterministic planning artifacts by investigating the Carta `.carta/` workspace and MCP document summaries, then generating structured `todo-tasks/` files with motivations and verifiability sections.

What is the best way to plan features in a Carta workspace without reading source code?

To plan features without source-code access, use Carta document and model summaries to understand schemas and constructs, enabling tradeoff-focused design discussions that clarify scope and constraints before implementation.

How do I generate todo-tasks for architecture investigations when source-code reads are prohibited?

Generate todo-tasks for architecture investigations by compiling MCP document summaries and workspace structures to guide decisions, enforcing no code edits and writing only to `todo-tasks/` using specified epic and task formats.

Does carta-builder require direct source-code access to create design specs?

No, carta-builder does not require source-code access. It explicitly enforces no source-code reads and no code edits, relying entirely on workspace and document compilation outputs to guide design decisions and produce planning artifacts.

Can I use Carta document summaries to evaluate design tradeoffs before implementation?

Yes, you can use Carta document summaries to evaluate design tradeoffs. The process helps you choose between options, clarifies scope and constraints, and documents the decision rationale before any implementation begins.

What format do todo-tasks need to follow for deterministic workflow planning in Carta?

Todo-tasks must follow a specified epic and task format that includes motivation, design decisions, and a required `## Verifiability` section to ensure deterministic, implementer-ready planning artifacts.
