First, summarize what it does, its dependencies, license status if identifiable, and any risks. Show the exact files you propose to add under .agents/skills/rexboard-board-and-chess/. Do not write files or run scripts until I approve.

After I approve, install the complete skill folder, including required referenced files, into that project location. Verify it is discoverable, then tell me its actual invocation name and how to use it. Do not claim it is installed until you have verified it.

RexBoard Board And Chess

Use this skill for the core RexBoard data model: a board with a grid, dimensions, chess pieces, tile layers, occupancy, and optional input events.

Use This First

Establish these before writing board logic:

Need	Decide
Coordinate system	Which `QuadGrid` or `HexagonGrid` backs the board
Board extent	Fixed `width`/`height`, `wrap`, or `infinity`
Layers	What each `tileZ` value means
Chess type	Phaser game object or plain data object
Input	Whether `board.setInteractive()` is needed

Required Setup

This skill assumes RexBoard setup and a grid are already available. If not, use rexboard-setup-and-factory and rexboard-grids-and-coordinates.

References

Read these only when needed:

references/board-config.md: board construction, embedded grid configs, wrap/infinity settings.
references/chess-model.md: tile/chess placement, tileZ layers, occupancy, blockers, and plain data pieces.
references/board-events.md: interactive tile, game-object, pointer, tap, press, and swipe events.
references/chess-recipes.md: reduced add/remove/move/swap/iterate recipes.

Core Rules

Board extends the logic board with scene input support; LogicBoard is the core data model.
Always create or pass a grid before board operations that require coordinate conversion.
Treat tileZ as part of the chess coordinate, not optional metadata.
Use align: true when adding or moving rendered chess that should snap to grid world coordinates.
Use isEmptyTileXYZ, tileXYZToChess, and tileXYToChessArray for occupancy checks.
Keep plain data chess and Phaser game object chess workflows distinct.

Gotchas

wrap and infinity change containment, neighbor, and movement behavior.
Board input events require board.setInteractive(...).
Some emitted event names are only obvious in plugins/board/board/input/*.js; inspect source when documenting exact events.
A tile can be occupied on one tileZ layer and empty on another.
