split_tile
Partition solution spaces into MECE subsets using specific attributes to systematically organize research ideas and analyze gaps in hierarchical tile-based exploration.
Instructions
Split a tile into MECE (Mutually Exclusive, Collectively Exhaustive) subsets using a specific attribute/dimension. This is the core operation of the tiling trees method - partitioning the solution space systematically. Use physics/math-oriented splits when possible.
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| tileId | Yes | ID of the tile to split | |
| splitAttribute | Yes | The attribute/dimension used to split (e.g., 'energy source', 'scale', 'physical mechanism', 'timeframe') | |
| splitRationale | Yes | Why this attribute was chosen for splitting | |
| subsets | Yes | The mutually exclusive and collectively exhaustive subsets |
Implementation Reference
- src/research-tree.ts:169-205 (handler)Core implementation of the split_tile tool logic in ResearchTreeManager class. Creates child tiles from subsets, updates parent with split info, and ensures tile hasn't been split before.splitTile( tileId: string, splitAttribute: string, splitRationale: string, subsets: Array<{ title: string; description: string; isLeaf?: boolean }> ): { parentTile: Tile; createdTiles: Tile[] } { const tile = this.tiles.get(tileId); if (!tile) { throw new Error(`Tile ${tileId} not found`); } if (tile.childrenIds.length > 0) { throw new Error(`Tile ${tileId} has already been split. Use addTilesToSplit to add more tiles.`); } // Create the child tiles const createdTiles = subsets.map((subset) => this.createTile( subset.title, subset.description, tileId, subset.isLeaf || false ) ); // Update parent with split information tile.splitAttribute = splitAttribute; tile.splitRationale = splitRationale; tile.isMECE = undefined; // Needs validation tile.isLeaf = false; // No longer a leaf tile.updatedAt = new Date(); return { parentTile: tile, createdTiles, }; }
