Telegram MCP Server & Channel Monitor

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations indicate readOnlyHint=false and destructiveHint=false, confirming this is a write operation that doesn't destroy data. The description adds that it sends media groups/albums (implying multiple items sent together as a unit) and specifies the 2-10 item range, which provides useful behavioral context beyond the annotations. However, it doesn't mention rate limits, authentication requirements, error conditions, or how the album appears in the chat interface.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise - just one sentence that efficiently communicates the tool's purpose, target, content type, and quantity constraint. Every word earns its place with no redundant information. The structure is front-loaded with the core action and resource.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given that there's an output schema (which handles return values), annotations covering safety profile, and a simple parameter structure, the description provides adequate context. It clearly explains what the tool does, what it sends, and the quantity constraints. For a media-sending operation with good structural support, this description is reasonably complete, though it could benefit from mentioning sibling tool relationships more explicitly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage (the schema has descriptions but they're in Korean, matching the description language), the description carries the full parameter documentation burden. It effectively explains the core parameters: it specifies the action (send media group), target (Telegram chat), media types (photos/videos), and quantity constraint (2-10 items). While it doesn't detail individual parameter fields like chat_id format or media item structure, it provides sufficient semantic context for the main operation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('전송합니다' - send) and resource ('텔레그램 채팅에 사진/동영상 앨범' - photo/video album to Telegram chat), and specifies the quantity constraint (2-10 items). It distinguishes itself from single-media sending tools like telegram_send_photo or telegram_send_video by mentioning '미디어 그룹' (media group/album). However, it doesn't explicitly contrast with telegram_send_with_buttons or other multi-message tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage context through the quantity constraint (2-10 media items) and media type specification (photos/videos), suggesting this is for sending albums rather than single media. However, it doesn't provide explicit guidance on when to choose this over alternatives like sending multiple individual messages or using other multi-content tools like telegram_send_with_buttons. No prerequisites or exclusions are mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
