products_batch_update

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

With no annotations provided, the description carries full burden for behavioral disclosure. It states this is an update operation (implying mutation) but doesn't mention permissions required, whether updates are atomic/partial, error handling for invalid batches, rate limits, or what the response contains. This is a significant gap for a batch mutation tool.

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 wasted words. It's appropriately sized for what it covers and front-loads the core action ('Update a batch of products').

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 batch mutation tool with no annotations, 0% schema description coverage, and no output schema, the description is incomplete. It doesn't address behavioral aspects (permissions, atomicity, errors), parameter details beyond a brief mention of 'idProperty', or what to expect in return. The context signals indicate high complexity that isn't adequately covered.

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. It mentions 'idProperty' but doesn't explain its relationship to the 'id' field in the schema or what 'unique values' means. It doesn't describe the 'inputs' array structure, required 'properties' object, or any of the nested property fields (name, price, etc.). The description adds minimal value 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 clearly states the verb ('Update') and resource ('batch of products'), and specifies the identification method ('by internal ID, or unique values specified by the `idProperty` query param'). However, it doesn't explicitly differentiate from sibling tools like 'products_update' (single update) or 'products_batch_create', which would require a 5.

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 like 'products_update' (single update) or 'products_batch_create'. It mentions the 'idProperty' parameter but doesn't explain when to use internal ID versus custom ID property, or any prerequisites for batch operations.

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