Format and deliver rich Telegram messages with HTML formatting via direct Telegram API. Auto-invoked by the main session for substantive Telegram output — no other skills need to call it. Decision rule: If your Telegram reply is >3 lines or contains structured data (lists, stats, sections, reports), spawn this as a Haiku sub-agent to format and send. Short replies (<3 lines) go directly via OpenClaw message tool. Handles: research summaries, alerts, status updates, reports, briefings, notifications — anything with visual hierarchy.
**Summary:** This update requires callers to explicitly specify the Telegram bot account for all deliveries; auto-selection of accounts is no longer allowed. - The bot account name (e.g., "main") must now be provided by the caller for every message; the skill will not auto-select or iterate accounts. - Session/task templates and documentation updated to require explicit `Bot account: <account_name>` specification. - Credentials section and all usage examples revised to validate and use only the specified account. - Added `metadata` with OS, binary, network, and credential requirements. - Improved error handling and validation message if account is missing or invalid. - No runtime/code file changes—documentation only.
