bulk_upload_replace_data_list

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. The phrase 'replace all entries' hints at a destructive overwrite, but it does not disclose whether the operation is irreversible, whether it requires special permissions, what happens to the existing list structure, or what the response looks like. Given the absence of annotations and the mutating nature of the tool, this is a significant gap.

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, concise sentence that front-loads the action ('Bulk replace'). It is appropriately sized for the simple purpose, though it could include a bit more detail without becoming verbose. The structure is clean and every word contributes to the meaning.

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 that this is a bulk mutation with no annotations and no output schema, the description is too sparse to be fully actionable. It lacks critical context such as the destructive/irreversible nature of the operation, prerequisites (e.g., the data list must exist), what the CSV format should be (headers, column structure), and the expected response. An agent would need to guess these details, making the description insufficient for reliable invocation.

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 'id' and 'data' are described in the input schema. The description adds no additional meaning beyond the schema, so the baseline of 3 is appropriate. The schema already explains that 'data' is CSV content and 'id' is the data list identifier, and the description does not clarify format or constraints further.

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 'Bulk replace all entries in a data list' uses a specific verb ('replace') and resource ('data list'), clearly indicating the action and scope. It distinguishes from sibling tools like bulk_upload_add_data_list and bulk_upload_remove_data_list by specifying 'replace all entries', which is a unique operation.

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 when to use the tool (when you need to replace all entries in a data list) but does not explicitly state alternatives or exclusion criteria. There is no mention of when to use bulk_upload_add_data_list or bulk_upload_remove_data_list instead, so usage guidance is only implied, not explicit.

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