create_chat_session

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

No annotations are present, so the description must fully disclose behavioral traits. It only states it creates a session and lists parameters. It does not mention whether the operation is destructive, if it requires specific permissions, or if there are limits on session creation.

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 short and to the point, with a clear one-line purpose followed by structured args and returns. It is front-loaded and efficient, though it could be slightly more detailed without losing conciseness.

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?

The tool is simple with two required parameters and an output schema (not shown). The description mentions a return value but is vague. It provides enough for a basic understanding but lacks completeness in usage context and behavioral details.

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 coverage is 0%, so the description must add meaning. The Args section provides brief explanations: 'Notebook ID for the session' and 'Session title'. This adds some context beyond the schema's type and title, but lacks details on constraints or formats.

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 clearly states 'Create a new chat session.' which is a specific verb+resource combination. It distinguishes from sibling tools like create_note or create_model. However, it could elaborate on what a chat session is in this context.

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 create versus update or delete a chat session. Sibling tools include update_chat_session and delete_chat_session, but the description does not clarify scenarios where creating is appropriate.

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