create_status_page

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

Annotations are all false, so the description carries the behavioral burden. It excellently discloses that pages are private by default, that public pages are served at unauthenticated URLs and expose monitor names, that slug conflicts return 409, that invalid check_ids return 400 with nothing saved, and that the free tier allows only one public page. This goes well beyond the annotations.

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 dense sentences with no filler. The purpose is stated first, followed by the primary use case and then the most critical behavioral caveat about privacy. 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 create tool with four parameters and no output schema, the description covers the key context: when to use it, the privacy implications, failure modes (400, 403, 409), and how to handle the optional slug safely. An agent has enough information to invoke it correctly and avoid the most common mistakes.

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 coverage is 100%, so the baseline is 3, but the description adds meaningful decision guidance: omit slug unless a specific URL is requested, random slugs are safer, private is the safer default for visibility, and monitor names may be sensitive. These are important operational semantics not fully captured in the schema alone.

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 uses a specific verb ('Create') and resource ('status page') and immediately defines what a status page is: a single page showing current status and recent history of chosen monitors. This clearly separates it from sibling tools like update_status_page, delete_status_page, and list_status_pages.

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 explicitly states when to use the tool: when monitor health needs to be visible to someone who cannot log in to the project. It gives strong contextual guidance about privacy and visibility but does not explicitly name alternatives or state when not to use it, so it falls just short of a 5.

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