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

It adds crucial behavioral context by specifying that it operates as a 'deep link' and targets the 'desktop app,' which is essential for an agent deciding whether to use a web-based or application-based tool. This context is not present in the structure or 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 two sentences are highly efficient. The first defines the mechanism, and the second immediately follows with practical use cases, maximizing information density without redundancy.

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?

The description provides all necessary context regarding the tool's scope (desktop app interaction) and acceptable input formats, making it complete for this type of OS-level deep linking utility.

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?

Since schema coverage is 100%, the description provides high-value semantics for the single required parameter. It clarifies that the 'page' input can be a 'Page id (UUID) or title (partial, case-insensitive),' informing the agent exactly what input format is acceptable.

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 specifies exactly what the tool does: 'Opens a Notion page in the desktop app (deep link).' This clearly differentiates it from tools that might just retrieve content (like reading a page).

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 use cases, stating the tool is 'Useful to let the user view or edit a page, or to pull an uncached page into the local cache.' While it doesn't name competing tools, the suggested intent is highly directional.

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