Api chat sessions create

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

Annotations already convey the safety profile (readOnlyHint=false, idempotentHint=false, openWorldHint=true, destructiveHint=false), so the description's burden is lighter, but it adds nothing beyond them. It does not say whether creating a session returns an identifier, whether a title/body is expected, or what the 'streaming' mention implies for this endpoint.

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 a single short sentence with no padding, so length is fine. But the one clause it contains is framework jargon about a different endpoint, so the brevity comes at the cost of any useful information.

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 non-idempotent, open-world create endpoint with an opaque body parameter and no output schema, the description should explain the expected payload and what gets returned. Neither is covered, leaving the agent unable to invoke the tool correctly without guessing.

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?

There is one parameter, an untyped free-form object named 'body' with 0% schema description coverage, and the description says nothing about it. An agent cannot tell whether body should carry a session title, an initial message, or be omitted entirely (default null).

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 restates the framework class rather than the action: 'ViewSet for chat sessions with streaming message endpoint' names a resource family but never says what 'create' does. Worse, the only concrete detail mentioned ('streaming message endpoint') belongs to the sibling chat_sessions_message_create, not to this tool, so it actively blurs 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?

There is no statement of when to call this versus chat_sessions_list, chat_sessions_message_create, or chat_sessions_upload_create. With dozens of sibling chat tools, an agent gets no routing signal at all from the text.

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