Update Document Title

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

Annotations already indicate a non-readonly, non-destructive write operation. The description adds value by revealing that the rename updates both workspace metadata and the internal page block title, which is not derivable from annotations alone. No contradiction exists.

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 a single, well-structured sentence that leads with the core action and then adds specific detail. Every word contributes value with no redundancy.

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 simple rename tool with annotations and an output schema present, the description adequately explains the tool's effect. It lacks edge-case or prerequisite details, but these are not necessary for such a straightforward operation.

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 schema describes docId and title, but the description clarifies that the title parameter affects both the sidebar and internal page block, adding meaning beyond the schema's 'New title'. With 67% schema coverage, the description partially compensates, though workspaceId remains unspecified.

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 'Rename a document' with a specific verb and resource, and further clarifies the scope by mentioning both the sidebar title and internal page block title. This distinguishes it from sibling tools like update_doc_icon or move_doc.

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 description implies usage for renaming documents but does not explicitly state when to use it versus alternatives or provide exclusions. It gives context about what is updated but no direct guidance on when this tool is preferred over others.

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