b24_chat_send

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states that a message is sent to private or group chat; it does not mention permissions, webhook requirements, side effects, idempotency, rate limits, or return behavior. The personal_webhook schema description hints at read-only behavior, but the tool description itself adds no behavioral depth.

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 a single, front-loaded sentence with no filler. It is concise and readable, though it could earn a 5 by adding usage routing in the same compact form.

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?

With no annotations, no output schema, and partial schema coverage, the description is too thin to be fully self-sufficient. It gives no guidance on when to prefer this tool over sibling messaging/notification tools, no expected result information, and no behavioral caveats.

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?

The description adds no parameter meaning beyond the schema, but the schema already documents 3 of 4 parameters, including important guidance for dialog_id and personal_webhook. The main gap is webhook_url, which lacks a description, so the overall parameter semantics is acceptable but not strongly enriched by the description.

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 verb ('Envía'), resource (mensaje), and target context (chat privado o grupal en el IM de Bitrix24). It is clear, though it does not explicitly differentiate from sibling tools such as b24_notify_send or b24_feed_post.

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 guidance about when to use this tool versus alternatives like b24_notify_send, b24_feed_post, or b24_call. The description implies IM chat usage but provides no exclusions, prerequisites, or routing hints.

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