Implementation Reference

• src/tools/file-tools.ts:286-326 (handler)

  The implementation of the delete_lines tool, which reads a file, splits its content into lines, uses splice to remove the specified range, writes the updated content back, and emits a change event.

    name: "delete_lines",
    description: "Delete a range of lines from a file. Line numbers are 1-based.",
    schema: {
      path: z.string().describe("Path to the file"),
      start: z.number().int().min(1).describe("First line to delete (1-based)"),
      end: z.number().int().min(1).describe("Last line to delete (1-based, inclusive)"),
    },
    handler: async (ctx) => {
      const { path, start, end } = ctx.args;
      validatePath(path);
      try {
        const content = readFileSync(path, "utf-8");
        const lines = content.split("\n");
  
        if (start < 1 || end > lines.length || start > end) {
          return makeTextResponse({
            error: `Invalid line range: ${start}-${end} (file has ${lines.length} lines)`,
            data: null,
          });
        }
  
        const deleted = lines.splice(start - 1, end - start + 1);
        writeFileSync(path, lines.join("\n"), "utf-8");
  
        await eventBus.emit("file:changed", {
          path,
          type: "modified",
        });
  
        return makeTextResponse({
          data: { deletedLines: deleted.length, path },
          metadata: { source: "fallback" },
        });
      } catch (err) {
        return makeTextResponse({
          error: `Failed to delete lines: ${(err as Error).message}`,
          data: null,
        });
      }
    },
