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

Annotations already indicate this is a write operation (readOnlyHint=false, destructiveHint=false, openWorldHint=true). The description adds a key behavioral detail: the page is public as soon as it exists, and the need for user confirmation. This goes beyond the annotations and helps the agent understand side effects and required pre-checks.

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 three sentences with zero filler. It front-loads the core action, immediately flags the public-visibility consequence, and then notes what is not covered. 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?

For a tool with 10 parameters and a nested sections array, the schema covers parameter details thoroughly, and the description covers the critical behavioral context (immediate public access, user confirmation, dashboard-only settings). No output schema exists, but the description doesn't need to explain returns. Slightly missing is explicit error handling or permission requirements, but overall adequate.

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 all parameters. The tool description does not add new parameter-specific semantics beyond what the schema provides (e.g., subdomain pattern, sections structure). Baseline 3 is appropriate since the description adds no extra meaning to parameters.

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 a specific verb (create) and resource (status page on hyperping.app subdomain), and specifies it includes sections of monitors and components. This distinguishes it from sibling tools like update_status_page or create_status_page_incident, so an agent knows exactly what it does.

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 explicitly instructs to confirm name, address, and services with the user first because the page becomes public immediately. It also notes that password protection, SSO, custom domain, and logo are set in the dashboard, implicitly excluding those from this tool. It does not explicitly contrast with update_status_page, but the usage context is clear.

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