update_file_library_sync_status

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

With no annotations, the description carries full responsibility for disclosure. It only states the action ('Update') without revealing side effects, reversibility, permission requirements, or what 'sync status' actually entails. There is no mention of what happens to the link or whether the update is destructive.

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, front-loaded sentence that wastes no words. It immediately communicates the action and resource. Despite being minimal, it is appropriately concise for the simplicity of the tool.

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 has no annotations and no output schema, so the description must provide context. It fails to explain what 'synchronization status' means, possible update values, whether a link must already exist, or any return behavior. The description is too sparse for an agent to confidently invoke the tool in a real workflow.

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 description coverage is 100% (both fileId and libraryId have descriptions). The tool description adds no additional meaning to the parameters, so the baseline of 3 applies. The description simply repeats the concept of a file->library link without elaborating on parameter roles.

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 a specific action ('Update') on a specific resource ('synchronization status of a file->library link'). While it does not differentiate from sibling tools like 'ignore_file_library_sync_status' or 'link_file_to_library', the core purpose is unambiguous and the verb+resource structure is strong.

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 provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, exclusions, or context. An agent has no information about whether this should be used instead of 'ignore_file_library_sync_status' or when a sync status update is appropriate.

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