Update a space

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

The description only repeats the HTTP method 'PATCH' and the endpoint. It adds no behavioral details beyond what annotations already imply (readOnlyHint=false). It does not disclose what fields can be updated, side effects, or error conditions, which is critical for a mutation tool without output schema.

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 extremely concise at 6 words plus the endpoint in parentheses. No wasted text; it efficiently conveys the core 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?

With no output schema and a complex nested input for 'body', the description is insufficient to fully inform the agent. It lacks details on what properties can be updated, how to construct the body, or what the response looks like, making it incomplete for an operation of this complexity.

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?

Input schema coverage is 100% with descriptions for both parameters. However, the description for 'body' is generic ('Request body as a JSON object, per the GitBook API'), offering minimal additional meaning beyond the schema. Baseline 3 is appropriate.

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 the verb 'Update' and the resource 'space', making the tool's purpose clear. However, it does not differentiate from sibling tools like gitbook_duplicate_space or gitbook_move_space, which are also mutations on spaces.

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. There is no mention of prerequisites, context, or conditions for use, leaving the agent to infer from the tool name alone.

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