chats_create

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

Annotations already declare readOnlyHint=false, destructiveHint=true and openWorldHint=true. The description adds a confirmation requirement and the fact that it 'reaches other people on the platform', which is useful, but the 'deletes, or redirects data' clause is generic boilerplate that never states what is actually affected by creating a chat.

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 action is front-loaded, but the middle sentence is generic policy boilerplate that does not earn its place, and the trailing endpoint/gRPC/socket parenthetical is debug metadata rather than agent-facing guidance.

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 destructive, open-world mutation with no output schema and 0% parameter coverage, the description should explain what is created, in which channel, and with whom. None of that is covered, leaving significant gaps for a tool with a required channelId.

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 0% and the description mentions none of the three parameters (name, channelId, participants). Only the vague term 'group' hints at participants; the required channelId and name are left entirely to the schema's bare examples.

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?

States a specific verb+resource ('Create a chat') and clarifies that it is a group where the platform supports them. However, it does not distinguish itself from the many sibling tools (e.g. channels_create, chats_update), so an agent gets a clear action but no sibling differentiation.

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 only guidance is a generic confirmation warning ('say exactly what will happen and get the user's confirmation first'), which is a policy reminder rather than when-to-use context. No conditions, prerequisites, or alternatives (e.g. channels_create) are named.

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