ai_create_session

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

There are no annotations, and the description adds no behavioral information. It does not disclose side effects, permissions, or any internal behavior beyond what the name already implies. The description is essentially a tautology.

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 brief, but this is under-specification rather than conciseness. It provides no substantive information beyond restating the tool's purpose.

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 create operation with no annotations and an output schema (not visible here), the description is severely lacking. It does not explain what an AI session is, the expected outcome, or any contextual details needed for correct invocation.

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 input schema has 0% description coverage, and the tool description does not explain the parameters 'name' or 'assistant_id'. The agent has no idea what values to provide or the meaning of these fields.

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 'Create an AI session' clearly states the action (create) and the resource (AI session). This is specific enough to distinguish from sibling tools like get_session or clear_session, though it does not elaborate on what an AI session is.

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?

No guidance is provided on when to use this tool versus alternatives. It does not explain the relationship to ai_list_assistants or ai_query_assistant, nor does it mention any prerequisites or exclusions.

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