Repository-wide instructions for agents

This file applies to the entire deck.gl-community repository. Directories may add more specific guidance in their own AGENTS.md files.

Tooling

Use the Yarn 4 workspace that ships with the repo. Install dependencies with yarn and run scripts via yarn <script> from the repo root. See package.json for the canonical script list.
Prefer TypeScript and ES module syntax when authoring source files. Most packages ship dual ESM/CJS bundles via build tooling defined per workspace package.
if any dependencies are changed, the yarn.lock file must be rebuilt by running yarn in the root before committing.

Run yarn lint or yarn lint-fix before committing JavaScript/TypeScript changes.
Run the relevant Vitest project: yarn test (Node), yarn test-browser, or yarn test-headless as appropriate for your change.

Follow the contribution flow in docs/CONTRIBUTING.md before landing breaking changes.
When adding or removing packages or examples, update any related documentation, sidebars, or release notes under docs/.
