user_telegram_user_post

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

No annotations are provided, so the description carries the full burden. It signals a mutation only implicitly through the HTTP verb, and says nothing about which settings are changed, whether changes are reversible, what permissions are required, or what the confirm/read-write preview mode means (that detail exists only in the schema). The 'Тег' and 'Спека' metadata are API spec bookkeeping, not behavior.

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 core sentence is short and front-loaded, but it is diluted by raw HTTP-method notation and tag/spec boilerplate ('Тег: Telegram bot', 'Спека: user') that carry no decision value for an agent.

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?

This is a mutation tool with no annotations, no output schema, and a nested body object whose properties are entirely empty ({}). The description supplies none of the compensating context an agent needs — what fields the body accepts, what the operation returns, or what the read-write preview mode implies — so it is materially incomplete.

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%, and the schema itself explains confirm's preview semantics and user_id's act-on-behalf meaning. The description adds no parameter detail at all, so this lands at the baseline of 3 for a fully-covered 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?

The Russian phrase 'Изменить настройки пользователя для Telegram бота' does give a verb (change) and a resource (Telegram bot user settings), and the 'POST /telegram/user' line confirms the write intent. However, it does not distinguish this from the sibling user_telegram_user_get or user_telegram_user_delete beyond the HTTP verb, so the agent must infer the difference from the name alone.

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 contains no when-to-use guidance, no prerequisites, and no reference to any alternative tool. With ~130 sibling tools available, the absence of any routing hint (e.g. use this vs. user_telegram_user_get for reading) leaves selection entirely to the name.

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