Create classification items

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

Beyond the annotations, it discloses that all items are added in one undo step, that item IDs must be unique within the system, and it gives the exact return shape including per-item error handling and created/failed counts. For a write tool with no output schema, this is substantial behavioral context.

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 two dense sentences, front-loading the action and then constraints and return shape. Every clause earns its place with no filler.

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 nested write tool with no output schema, the description covers purpose, nesting, uniqueness, undo behavior, and return format. It could be slightly more explicit about partial success semantics, but overall it is quite complete.

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 75%, and the description mostly restates what the schema already documents: the nested item shape, optional parent, and before/append insertion. It adds little new parameter meaning beyond what is already in the field descriptions.

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 states a specific verb ('Adds') and resource ('classification items') with the scope 'to an existing classification system'. This implicitly distinguishes it from create_classification_system and from modify/delete item tools, but it never names a sibling alternative, which keeps it from 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?

Usage is implied by 'existing classification system' and the detailed insertion behavior, but the description never states when to use this tool instead of modify_classification_items, import_classifications_xml, or create_classification_system. No exclusions or alternative routing are provided.

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