Should I use this
Quality & Safety
A
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
~12,436Tokens (tool definitions)
~4.0 KBTypical response size
Significant attention impact (9.72% of 128k context)
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

}π’get_formatting_capabilities
Use this when composing or formatting any Postlyra post: call it FIRST, once per task. Postlyra creates beautifully structured rich Telegram posts, illustrated instructions, articles and presentations. Returns the complete RichDocument contract: exact JSON examples for every block and inline mark, nesting, limits, file uploads, error recovery, presets and which tool to use next. Use this contract for formatting; Telegram MarkdownV2/parse_mode documentation is not needed.

}π’search_post_drafts(query, limit, cursor)
Use this when finding an existing draft by topic, title or content. Search first when draftId is unknown; do not ask for a link. Matches all keywords/fragments in title and rich text, ignoring case. Empty query lists recent drafts. Follow nextCursor while hasMore. For an in-chat card, pass the returned draftId as postId to show_post_card; use preview_post for a screenshot/browser preview. Returns owner-only IDs and snippets. Never edits, enables sharing or publishes.

}π‘create_post_draft(topic, style, formatPreset, language, channelId, ...)
Use this when creating a Telegram draft. Read get_formatting_capabilities; prefer finished richDocument, which overrides text/preset/template. Bind mediaFile1..mediaFile6 or mediaFiles slots as media.src. Returns draftId, JPEG and public preview link. Display the image in the FINAL answer via native attachment or display.imageMarkdown. Inspect preview_post. May fetch external image URLs during import or screenshot rendering. Never publishes.

}π΄update_post_draft(draftId, instructions, text, richDocument, references, ...)
Use this when editing a draft. Read preview_post and get_formatting_capabilities. Send the complete edited richDocument, preserving untouched content and media; text replaces layout. Bind imported file slots as media.src. Returns JPEG and enables a public preview link. Display the image in the FINAL answer via native attachment or display.imageMarkdown. Inspect preview_post. May fetch external image URLs during import or screenshot rendering. Never publishes.

}π΄publish_post(draftId, channelId, confirmed, confirmationText, idempotencyKey)
Use this when the user explicitly authorizes publishing a reviewed existing Postlyra rich draft to a connected Telegram channel. Resolve channelId using list_channels, inspect preview_post, and supply confirmed=true plus confirmationText containing the user's authorization. Reuse idempotencyKey on retry. Queued/retrying means pending, not delivered. This is the external publication action; draft tools never send.

}π’show_post_card(postId)
Use this when the author asks to show a post card inside the chat or choose publication controls there. After search_posts or search_post_drafts, pass the found post ID as postId.

If unavailable, refresh the connection's tool metadata; clients without UI retain text/tool workflows.
