Implementation Reference

• src/index.ts:435-455 (handler)

  Handler for the delete_mode tool: extracts slug, reads config, removes the matching mode, persists changes, and returns success message or error if not found.

  case 'delete_mode': {
    const { slug } = request.params.arguments as { slug: string };
    const config = await this.readConfig();
    const index = config.customModes.findIndex((m) => m.slug === slug);
  
    if (index === -1) {
      throw new McpError(ErrorCode.InvalidParams, `Mode not found: ${slug}`);
    }
  
    config.customModes.splice(index, 1);
    await this.writeConfig(config);
  
    return {
      content: [
        {
          type: 'text',
          text: `Mode "${slug}" deleted successfully`,
        },
      ],
    };
  }

• src/index.ts:291-304 (registration)

  Tool registration in list_tools handler: defines name, description, and input schema for delete_mode.

  {
    name: 'delete_mode',
    description: 'Delete a custom mode',
    inputSchema: {
      type: 'object',
      properties: {
        slug: {
          type: 'string',
          description: 'Slug of the mode to delete',
        },
      },
      required: ['slug'],
    },
  },

• src/index.ts:294-303 (schema)

  Input schema validation for delete_mode tool: requires a string 'slug' parameter.

  inputSchema: {
    type: 'object',
    properties: {
      slug: {
        type: 'string',
        description: 'Slug of the mode to delete',
      },
    },
    required: ['slug'],
  },
