Create Data Source Item

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

Annotations indicate it's non-destructive, non-idempotent, and not read-only. The description adds no further behavioral context (e.g., idempotency implications, permission requirements, side effects like creating duplicate items on repeat calls). With annotations present, some burden is lifted, but the description should at least clarify that each call creates a new page.

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?

Two sentences: first states the action, second gives a key usage tip. No redundant information. Front-loaded and efficient.

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 three parameters, no output schema, and sibling tools, the description covers the essential action and parent identifier. But it lacks guidance on: what happens if 'properties' do not match schema, whether the tool supports nested objects, and what the response includes (e.g., created page ID). Also does not differentiate from similar creation tools.

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 coverage is 100% and includes descriptions. The description adds important value for the 'data_source_id' parameter by specifying it must be the data source ID, not database ID. This is not in the schema description. Other parameters (format, properties) are already well-described in the schema, so the description's contribution is moderate.

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 it creates a new page item in a Notion data source. It distinguishes parent type (data_source_id vs database_id). However, 'page item' is slightly ambiguous; could specify that it creates a page (row) within a database represented as a data source.

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?

Provides a critical guideline: use data_source_id not database_id. But no guidance on when to use this tool versus its sibling 'notion_create_data_source_item_from_values' or other creation tools. Does not mention prerequisites or when not to use.

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