Instructions

Implementation Reference

• src/tools/level-management.ts:36-53 (registration)

  Complete tool registration for create_level including name, description, input schema, and handler function.

  {
    name: 'create_level',
    description: 'Create a new empty ice puzzle level. This becomes the current working draft.',
    inputSchema: {
      type: 'object',
      properties: {
        name: { type: 'string', description: 'Level name' },
        width: { type: 'number', description: 'Grid width (5-25, default 10)', minimum: 5, maximum: 25 },
        height: { type: 'number', description: 'Grid height (5-25, default 10)', minimum: 5, maximum: 25 },
      },
      required: ['name'],
    },
    handler: async (args) => {
      const draft = draftStore.createDraft(args.name, args.width, args.height);
      const viz = renderLevel(draft, { showCoords: true });
      return { content: [{ type: 'text', text: `Level "${args.name}" created!\n\n${formatDraftSummary(draft)}\n\n${viz}` }] };
    },
  },

• src/tools/level-management.ts:39-47 (schema)

  Input schema defining the accepted arguments: name (required string), width (optional number 5-25, default 10), height (optional number 5-25, default 10).

  inputSchema: {
    type: 'object',
    properties: {
      name: { type: 'string', description: 'Level name' },
      width: { type: 'number', description: 'Grid width (5-25, default 10)', minimum: 5, maximum: 25 },
      height: { type: 'number', description: 'Grid height (5-25, default 10)', minimum: 5, maximum: 25 },
    },
    required: ['name'],
  },

• src/tools/level-management.ts:48-52 (handler)

  Handler function that creates a new level draft using draftStore.createDraft() and returns a formatted response with level summary and visualization.

  handler: async (args) => {
    const draft = draftStore.createDraft(args.name, args.width, args.height);
    const viz = renderLevel(draft, { showCoords: true });
    return { content: [{ type: 'text', text: `Level "${args.name}" created!\n\n${formatDraftSummary(draft)}\n\n${viz}` }] };
  },

• src/store/draft-store.ts:88-116 (helper)

  The createDraft method in DraftStore that initializes a new DraftState with default positions (bottom-left start, top-right goal), empty obstacles/warps, and resets history.

  createDraft(name: string, width: number = 10, height: number = 10): DraftState {
    this.warpCounter = 1;
    this.undoStack = [];
    this.redoStack = [];
    this.lastSolvableSnapshot = null;
    const draft: DraftState = {
      id: null,
      previewId: null,
      name,
      description: '',
      gridWidth: width,
      gridHeight: height,
      par: 0,
      startPosition: { x: 1, y: height - 2 }, // bottom-left
      goalPosition: { x: width - 2, y: 1 }, // top-right
      obstacles: [],
      warpPairs: [],
      thinIceTiles: [],
      pushableRocks: [],
      pressurePlate: null,
      barrier: null,
      manualSolveMechanicsBaseline: null,
      manualSolveFingerprint: null,
      isDirty: false,
      lastSolverResult: null,
    };
    this.currentDraft = draft;
    return draft;
  }

• src/tools/level-management.ts:14-32 (helper)

  formatDraftSummary helper function used by the handler to display level information including grid size, par, start/goal positions, obstacles, warps, and solver status.

  function formatDraftSummary(draft: DraftState): string {
    const solverInfo = draft.lastSolverResult
      ? formatSolverResult(draft.lastSolverResult)
      : 'Not yet solved';
    return [
      `Name: ${draft.name}`,
      `Grid: ${draft.gridWidth}x${draft.gridHeight}`,
      `Par: ${draft.par > 0 ? draft.par : 'not set'}`,
      `Start: (${draft.startPosition.x}, ${draft.startPosition.y})`,
      `Goal: (${draft.goalPosition.x}, ${draft.goalPosition.y})`,
      `Obstacles: ${draft.obstacles.length}`,
      `Warps: ${draft.warpPairs.length} pairs`,
      `Thin Ice: ${draft.thinIceTiles.length}`,
      `Pushable Rocks: ${draft.pushableRocks.length}`,
      draft.pressurePlate ? `Pressure Plate: (${draft.pressurePlate.x}, ${draft.pressurePlate.y})` : '',
      draft.barrier ? `Barrier: (${draft.barrier.x}, ${draft.barrier.y})` : '',
      `Solver: ${solverInfo}`,
    ].filter(Boolean).join('\n');
  }
