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

Annotations already declare the write profile (readOnlyHint=false, openWorldHint=true, idempotentHint=false, destructiveHint=false). The description adds genuinely new behavioral context: the page is publicly exposed immediately upon creation, user confirmation is required, and several common settings are not settable through this tool. It stops short of saying anything about failure modes or what is returned.

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?

Three sentences, no waste, and the highest-risk fact (the page goes public immediately, confirm first) is front-loaded right after the purpose statement. 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 10-parameter creation tool with full schema coverage, annotations covering the safety profile, and no output schema, the description supplies exactly the missing pieces: public exposure, confirmation prerequisite, and what must be done in the dashboard instead. Nothing an agent needs to call this correctly is absent.

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% and each parameter (including nested section services with their ID prefixes and the paused-monitor refusal) is documented in the schema itself. The description's mention of sections of monitors/healthchecks/components/servers echoes the schema but adds no syntax or format detail beyond it, so the baseline 3 applies.

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?

States a specific verb (Create) and resource (status page) plus the scope (hyperping.app subdomain) and what the page is composed of (sections of monitors, healthchecks, components, servers). An agent can distinguish it from update_status_page or add_status_page_services without opening any schema.

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?

Gives a clear precondition — the page is public the moment it exists, so confirm name, address and services with the user first — and explicitly routes password protection, SSO, custom domains and logos out of scope (set in the dashboard). It does not name sibling tools as alternatives, so it stops short of a full when/when-not routing map.

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