batch_update_documents

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

With no annotations provided, the description carries full burden but only states the basic operation. It doesn't disclose behavioral traits such as permissions required, whether updates are atomic or partial, error handling for failed updates, rate limits, or what happens to unspecified fields. 'Update' implies mutation but lacks critical details for safe usage.

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, efficient sentence with zero waste. It's appropriately sized and front-loaded, directly conveying the core functionality without unnecessary elaboration.

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?

Given the complexity of a batch mutation tool with no annotations, 0% schema coverage, and no output schema, the description is incomplete. It lacks details on usage context, parameter semantics, behavioral implications, and expected outcomes, making it inadequate for safe and effective tool selection.

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 0%, so the description must compensate but adds no parameter information. It doesn't explain the 'updates' array structure, required 'documentId', optional fields like 'title' and 'text', or the 'append' boolean behavior. The description fails to provide meaning beyond the bare schema.

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 'Update multiple documents at once' clearly states the action (update) and resource (documents) with a specific scope (multiple/batch). It distinguishes from single-document updates like 'update_document' by emphasizing batch capability, though it doesn't explicitly name alternatives.

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 like 'update_document' or 'batch_create_documents'. The description implies batch operations but doesn't specify prerequisites, constraints, or comparative use cases with sibling tools.

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