create_paragraph

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

Without annotations, the description carries the full burden. It states that the tool creates a new paragraph, which is non-destructive, but does not disclose potential side effects (e.g., shifting existing paragraphs when inserting at an index). The behavior is basic and implied, so a 3 is appropriate.

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, front-loaded sentence that covers the core action and optional parameters. Every word earns its place, with no waste.

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 simple create tool with three parameters, the description is mostly complete. It could mention the return value or that inserting at an index shifts positions, but given the simplicity and schema richness, it is nearly sufficient.

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 the schema already explains each parameter. The description adds 'Optionally specify text and position index', which merely restates the schema without adding new meaning. Baseline 3 is correct.

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 'Add' and the resource 'paragraph to a notebook', making the purpose unambiguous. However, it does not explicitly differentiate from sibling tools like 'create_notebook' or 'run_paragraph', which reduces the score from perfect.

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 mentions optional parameters (text and position index) but provides no guidance on when to use this tool versus alternatives like 'update_paragraph' or 'delete_paragraph'. No when-not-to-use or context for selection is provided.

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