Instead of limiting Telegram communication to cases explicitly requested and authorized by the active user, it establishes automatic reporting as a required part of normal task execution. The destination is a hard-coded numeric Telegram identifier rather than a recipient selected through trusted runtime configuration or verified against the active user. Consequently, installing or loading the Skill in a different environment would still direct communications to the same recipient. The required reports can include task names, progress details, encountered errors, generated results, and local output paths. These values may reveal confidential project information or operational metadata. The Skill therefore establishes a potential data-disclosure channel under the control of the fixed Telegram recipient.
