Behavior2/5

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

No annotations are provided, so the description bears the full burden of behavioral disclosure. It only says 'Delete' without explaining whether deletion is permanent, whether special permissions are required, or what side effects occur. No additional context is given.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, short sentence with no redundant words. It is front-loaded and easy to parse, earning its place as a concise description.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite the low complexity, the description is under-specified for a mutation tool. It does not mention that deletion is likely permanent, what the project parameter does, or any prerequisites. The output schema exists, so return values need not be described, but the tool still lacks important contextual depth.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description does not compensate. It only mentions 'by ID' without clarifying that this maps to item_id or explaining the optional project parameter. The schema provides no descriptions, so the description adds almost no meaning to the parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Delete a dataset item by ID' clearly states the action (delete), the resource (dataset item), and the method (by ID). It distinguishes itself from sibling tools like get_dataset_item and create_dataset_item, which are different CRUD operations.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No usage guidance is provided. The description only states what the tool does, with no mention of when to use it, when not to, or alternatives. There are no prerequisites or exclusions.

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