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

The description adds meaningful behavioral details beyond the annotations, such as 'An omitted field is left alone' and 'Changing the slug moves the public URL and breaks existing links.' The 'Not read-only; idempotent' phrase largely restates the annotations, but the additional side-effect warning is valuable.

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 and front-loaded with the core actions, followed by important behavioral caveats. Every sentence contributes useful information, and there is no padding or unnecessary elaboration.

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 rich schema, annotations, and output schema, the description covers all essential calling context: what can be updated, how omitted fields behave, and the destructive consequence of changing the slug. No critical information for invoking the tool correctly is missing.

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 schema already documents the meaning and role of each parameter. The description reinforces that omitted fields are left unchanged and that new_slug is destructive, but it does not add substantial meaning beyond the schema.

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 identifies the resource (a status page) and the specific actions available: rename, change slug, publish, and unpublish. It is more specific than the generic title, though it does not explicitly name sibling tools like update_status_page_component to draw the contrast.

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 usage context is implied through the listed operations, but there is no explicit guidance about when to choose this tool over related siblings such as create_status_page or update_status_page_component. An agent can infer the use case, but the description does not state exclusions or alternatives.

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