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

Annotations already declare readOnlyHint=true and destructiveHint=false. The description adds valuable context about the data source (local desktop app cache), that no API token is required, and the condition that only visited/offline pages are cached. This goes beyond the annotations and explains behavior.

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 with zero filler. The main purpose is front-loaded, followed by essential caveats. Every sentence 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?

The tool is simple with one optional parameter and an output schema. The description covers the scope, source, and limitations, making it fully complete for the agent to invoke correctly.

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 'limit' parameter is fully documented in the schema. The description does not add any extra detail about parameters, which is acceptable given the schema already covers it. Baseline 3 is appropriate.

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 lists Notion pages cached on the Mac, including the kinds of info (titles, last edited, hierarchy) and sort order (newest first). It distinguishes itself from sibling tools like notion_search or notion_read_page by specifying the local cache 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?

The description implies when to use this tool: when you need cached pages from the local Notion app without API access. It notes the limitation that only visited or offline-marked pages are cached, which helps the agent decide whether this tool fits. However, it doesn't explicitly name alternative tools like notion_search.

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