create_dataset_run_item

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

With no annotations, the description must fully disclose behavior. It mentions 'flush the ingestion write', hinting at a side effect, but does not clarify what that means or any implications (e.g., data persistence, performance impact). It lacks details on required permissions, reversibility, or response behavior.

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 sentence with two clauses, which is relatively concise but not optimally structured. The phrase 'flush the ingestion write' is tacked on without explanation, reducing clarity. Could be reordered for better front-loading.

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?

Despite a full schema and output schema, the description lacks context about the relationship between dataset runs, items, and the 'ingestion write' concept. It does not explain when this tool is appropriate or what the side effect entails, leaving gaps for an agent.

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%, so baseline is 3. The description adds no additional parameter meaning beyond what the schema already provides, such as format or context for 'run_name' or 'dataset_item_id'.

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 tool creates a dataset run item, specifying the verb and resource. It distinguishes from siblings like 'create_dataset_item' by adding 'flush the ingestion write', though this phrase is somewhat cryptic. It's specific enough to avoid confusion with other create tools.

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 'create_dataset_item' or 'create_dataset'. The description does not mention prerequisites, context, or situations where this tool should not be used.

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