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

With no annotations, the description carries the full burden. It usefully discloses the tier max_endpoints cap, but says nothing about authentication, what happens when the cap is exceeded, whether the endpoint is immediately active or paused, or name-uniqueness behavior for a write operation.

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 short sentences with the purpose front-loaded and the quota constraint immediately after. Nothing is wasted or buried.

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 mutation tool with no annotations, no output schema, and four undocumented parameters, the description is too thin. It should convey invocation constraints and basic parameter meaning to compensate for the structured-data gaps.

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 0%, so the description must explain url, name, method, and interval_seconds, yet it mentions none of them. The schema's defaults (method=GET, interval_seconds=900) provide a little implicit meaning, but format expectations for url and uniqueness of name are undocumented anywhere.

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 ("Create a new monitored endpoint"), which clearly separates it from delete_endpoint and update_endpoint_interval. It stops short of naming a sibling or clarifying scope (e.g. user vs workspace), so it is clear but not fully differentiated.

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?

There is no when-to-use guidance, no prerequisites, and no reference to alternatives among the many create_* and *_endpoint siblings. The only contextual hint is a quota note about the tier's max_endpoints cap.

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