notion_import_file_from_url

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

No annotations exist, so the description carries full responsibility. It discloses async polling behavior, plan-dependent size limits, the absence of sha256 reporting, and the server-side transfer path without sending bytes through this server. This is exemplary transparency for a tool with no annotations.

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 compact—four sentences—with the core purpose front-loaded. Every sentence adds essential context: constraints, async behavior, size limits, and integrity caveat. It is dense but not bloated, and each statement earns its place.

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's complexity (async import, size limits, integrity concerns) and the presence of an output schema, the description covers all necessary operational aspects. It explains the critical behaviors without needing to describe return values, which are already handled by the output schema.

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?

With 0% schema description coverage, the description compensates well by explaining url requirements, filename semantics (determines block type), wait_seconds as polling timeout, and referencing notion_upload_file for parent_page_id and position. However, the caption parameter is not mentioned, leaving a gap for a minor field.

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 opens with a specific action: 'Import a file into Notion directly from a public HTTPS URL' and clearly distinguishes this tool from notion_upload_file by noting the bytes go Notion-side, never through the server. It also references notion_upload_file for parameter behavior, making the scope and differentiation explicit.

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?

It provides clear usage context: url must be publicly accessible, filename must have an acceptable extension, and the import is asynchronous with wait_seconds timeout. It recommends notion_download_file for integrity checks, offering an alternative for a related need, but does not explicitly state when to prefer this over notion_upload_file for local files.

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