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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered structurally. The description adds real operational context beyond that: this is an aggregate snapshot that collapses several sibling list calls into one, and it enumerates the freshness signal ('last update') the agent will receive.

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 returned content is front-loaded in the first sentence, followed by a short directive and the raw endpoint. Efficient and scannable, though the REST path line is mildly redundant for an agent that already has the tool binding.

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?

No output schema exists, so the description carries the burden of describing return values, and it does so thoroughly (overall status, components, containers, incidents, maintenance windows). For a zero-required-parameter read tool, nothing needed to invoke or interpret it 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?

With 100% schema description coverage and a single optional parameter whose default is documented in the schema, the baseline is 3. The description's endpoint line echoes the '{statuspage_id}' placeholder but adds no format, constraint, or default behavior 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?

States a specific verb and resource ('current state of the status page') and enumerates the exact payload: overall status, components/containers with status codes and last update, open incidents, active/upcoming maintenance. The 'in one call' framing distinguishes it from the granular siblings ('list_components', 'list_active_incidents', 'list_maintenance') without opening their schemas.

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?

'Start here' is an explicit entry-point recommendation, which tells the agent to call this before the per-resource list tools. It stops short of explicitly naming the alternatives or stating exclusions, so it is clear context rather than full routing guidance.

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