notion_create_database

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

With no annotations, the description carries the full burden. It does disclose a critical non-obvious behavior: the JSON payload must be written to a file and passed via file_path, and it clarifies the creation scope. However, it does not mention permissions, idempotency, error behavior, or any side effects beyond the creation itself.

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 with zero filler. The most urgent operational requirement (write JSON to file first) is front-loaded in all caps, and the core action is stated immediately after. Every word contributes.

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 two-parameter tool with 100% schema coverage, the description covers the essential non-obvious requirement (file-based payload), the required payload fields, and the resource being created. It does not explain the structure of the parent object or what happens after creation, but the schema and extract parameter cover most of the remaining operational context.

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 baseline is 3. The description reinforces that the file must contain 'parent', 'properties', and optionally 'title' but adds no meaning beyond what the file_path parameter description already provides. No additional parameter semantics are introduced.

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 and resource: 'Creates a database as a subpage in a specified parent.' This clearly distinguishes it from sibling tools like notion_create_page and notion_retrieve_database, and the parent/subpage scope adds precision beyond the tool name.

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 gives no guidance on when to use this tool versus alternatives among the siblings, such as notion_create_page or notion_update_database. The 'IMPORTANT' instruction explains how to call the tool (write JSON to a file first) but does not cover when it is the right choice or when another tool should be preferred.

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