status_page_overview

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

Annotations already declare readOnly/idempotent/non-destructive, so the description's main added value is the explicit auth disclosure 'No credentials needed', which tells the agent this is an unauthenticated public read. It also describes the return payload shape, which matters since there is no output schema; it does not cover error behavior for an unknown slug.

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?

A single sentence, front-loaded with the resource and followed by the returned contents plus the no-credentials note. Every clause carries information an agent needs; nothing is padded.

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 one-parameter, read-only, non-openWorld tool with no output schema, the description adequately covers what comes back and the auth posture. The only gap is failure behavior when the slug does not resolve to a public page.

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 the slug parameter already documents its format and the /status/<slug> address pattern. The description adds no further parameter meaning, 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+resource ('Current state of a public status page') and enumerates exactly what is returned: overall status, per-component status and 90-day uptime, and active incidents. This clearly separates it from write-oriented siblings like update_status_page, though it does not explicitly name status_page_incidents or status_page_maintenance as alternatives.

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?

Usage is only implied: an agent can infer this is the read path for a status page's public snapshot, reinforced by 'No credentials needed'. There is no explicit when-to-use/when-not guidance and no mention of the sibling tools (status_page_incidents, status_page_maintenance) that offer narrower slices of the same resource.

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