What does the Figram core package handle?

The core package is dependency-free and manages the entire data flow from YAML input to final diagram patches, including validation, normalization, and diffing.

What is the difference between DSL Types and IR Types?

DSL Types represent raw user input from YAML, while IR Types are the normalized Internal Representation used for diffing and final rendering.

How do I add a new node property to the diagram?

To add a property, you must update the DSLNode and IRNode types, add validation logic in validate.ts, and set default handlers in normalize.ts.

How are tests executed for core development?

Tests are co-located with source files (*.test.ts) and are executed using the Bun test runner via 'bun test packages/core/'.

デザインツール

Manages the core TypeScript engine for Figram, handling DSL processing, validation, and architecture diagram differencing logic.

概要

The core-development skill equips Claude with specialized knowledge of the Figram engine, which transforms YAML-driven DSLs into FigJam architecture diagrams. It provides deep context on the dependency-free core package, covering the entire data flow from validation and normalization to Internal Representation (IR) and patch generation. This skill is essential for developers modifying Figram's underlying logic, adding new diagram properties, or refining the diffing algorithm that ensures efficient updates to visual layouts.
