user_telegram_web_auth_init_get

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 does disclose non-obvious behavioral content — that this initializes an OIDC flow producing state, nonce and PKCE — which is real context beyond the schema. It still omits auth/credential requirements, whether it issues a redirect, and what the caller receives.

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?

It is short and the purpose line comes first, but it spends lines on low-value boilerplate — the raw HTTP path duplicates the tool name, and 'Тег: Telegram bot' / 'Спека: user' are metadata rather than usable instruction.

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 security-sensitive auth-init endpoint with zero annotations and no output schema, the definition is too thin: it never explains credential/permission needs, what the init returns, or how it relates to the sibling start/post/callback tools an agent must sequence after it.

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%, so the schema already documents limit, offset and user_id; baseline is 3. The description adds no parameter meaning at all, and notably the listed params (pagination, user_id) look unrelated to an OIDC init step, which it does not clarify.

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 verb and resource ('GET /telegram/web/auth/init', 'Инициализация Telegram Login OIDC'), so the basic action is identifiable. However, it gives no differentiation from near-identical siblings such as user_telegram_web_auth_start_get, user_telegram_web_auth_post, user_telegram_web_callback_get and user_telegram_webapp_auth_get, leaving the agent unable to tell which init/start step it should call.

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?

There is no when-to-use guidance, no prerequisites, and no mention of the alternative Telegram auth endpoints. The word 'init' weakly implies it is a first step, but nothing tells the agent when to prefer this over the sibling start/callback/webapp variants.

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