Create Data Source Item

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

Annotations already indicate destructiveHint=false and readOnlyHint=false, so the description only repeats that it creates. No additional behavioral context is provided about side effects, authentication, rate limits, or response format.

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 sentences, front-loading the purpose and a key usage guideline. Every word is informative and no extraneous content.

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 the tool has a nested object parameter (properties) and no output schema, the description lacks guidance on what the return value looks like, error handling, or success behavior. More context would be beneficial for a create operation.

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%, baseline 3. The description adds meaning by clarifying the role of data_source_id (not database_id) and that properties should match the schema. This goes beyond the schema 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 clearly states the verb 'Create' and resource 'new page item in a Notion data source', and distinguishes by specifying to use data_source_id instead of database_id. However, it does not explicitly differentiate from the sibling tool 'notion_create_data_source_item_from_values', which has a similar purpose.

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 provides a specific guideline: 'Use the data_source_id, not the database_id, as the parent.' This implies when to use this tool over database_id-based tools. However, it does not mention when to use this versus other related tools like 'notion_create_data_source_item_from_values' or prerequisites.

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