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

With no annotations, the description carries the burden and usefully discloses that this performs a REAL external send during human takeover and requires exact-text approval. It does not cover permissions, rate limits, failure behavior, or whether delivery is idempotent.

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 two tightly written sentences with the core action and critical precondition front-loaded. Every phrase contributes useful information without repetition.

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?

It covers the most important safety context for a real outbound message, but with no annotations, no output schema, and low parameter coverage it remains incomplete on chat_id semantics and what a successful or failed send returns.

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 only 33%, so the description should compensate for undocumented parameters. It does not explain chat_id at all and only vaguely implies the message via 'exact text', leaving key parameter meaning to the schema gaps.

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 states a specific action and resource: sending a REAL Telegram message from the bot to a person. It also distinguishes the tool from its preview counterpart by naming preview_send_telegram_message and the approval requirement.

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?

It gives an explicit prerequisite: use only after preview_send_telegram_message and after the user approves the exact text. This clearly routes the agent away from calling it directly without preview or approval.

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