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

Description goes beyond annotations by disclosing the 48-hour time constraint, the bot-ownership requirement, and error handling details. Annotations indicate idempotentHint=true but description explains the 'message is not modified' error, adding behavioral context.

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?

Description is well-structured with a clear overview, constraints, Args list, Returns, and Error Handling sections. Every sentence provides value, no fluff, and the most critical info is front-loaded.

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 4-parameter tool with no output schema, description covers purpose, constraints, and error handling. Not specifying exact return fields is a minor gap, but 'Confirmation that the message was updated' is adequate given simplicity.

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 100% schema description coverage, the baseline is 3. The description partly repeats schema but adds minor value, such as character limits for text and formatting explanations for parse_mode. No significant new meaning beyond schema.

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?

Description clearly states 'Edit the text of a previously sent bot message.' The verb 'edit' and resource 'text of a previously sent bot message' are specific. It distinguishes from siblings like telegram_send_message (send new) and telegram_delete_message (delete).

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?

Description specifies that only messages sent by this bot and younger than 48 hours can be edited, providing clear context. Error handling gives situations when it won't work. However, it does not explicitly name alternative tools for when not to use this tool.

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