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

Annotations already disclose the safety profile (readOnly=false, destructive=false, openWorld=true, idempotent=false), so the description only needs to add context. It contributes the @BotFather prerequisite and the accepted chat target types, but never addresses the non-idempotent behavior — e.g., what happens if the same bot/chat is connected twice — which is the one trait the annotations flag as risky.

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?

Two short sentences with the action front-loaded and the prerequisite sequence immediately after. No filler, no repetition of the title, every clause earns its place.

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?

For a two-parameter connect tool with no output schema and annotations covering safety, the description supplies the essential setup prerequisite and target scope. It is nearly complete; only post-connection behavior and duplicate-connect handling are unaddressed.

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?

Schema description coverage is 100%, with chat_id formats and the bot_token source fully documented in the schema itself. The description restates 'pass the bot token and the chat ID (user, group, or channel)' without adding syntax or format detail beyond what the schema already carries, so the baseline 3 applies.

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?

States a specific verb and resource (connect a Telegram bot) plus the required setup path, so the agent knows exactly what the call accomplishes. It does not explicitly differentiate itself from the connect_* siblings, but the platform-specific naming makes the distinction obvious without opening schemas.

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?

Provides a prerequisite workflow (create the bot with @BotFather first, then pass token and chat ID), which is useful implied guidance for invoking it correctly. It offers no when-to-use vs. when-not guidance and does not mention chirpie_disconnect_account or reconnection scenarios as alternatives.

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