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

No annotations exist, so the description carries the burden, and it does disclose the data source (official Statuspage) and freshness (refreshed every 3 minutes), which are useful behavioral traits. It says nothing about coverage limits, caching, or what happens for an unknown service key.

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 front-loaded sentence with no wasted words, though it packs the service list and refresh cadence into a slightly dense clause.

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 simple read tool with one optional param and full schema coverage, the description is adequate: source and freshness are covered. It remains silent on the no-argument default behavior and return shape, leaving gaps for an agent deciding whether to pass a service key.

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% and the single optional 'service' parameter is documented in the schema with an example, so the baseline is 3. The description's mention of service names adds marginal context but no syntax 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 resource (live status feeds for named services via Statuspage) with a clear refresh property, which distinguishes it from siblings like check_ip and my_exit. It does not explicitly contrast with ai_availability, which is the closest sibling, so it misses the top mark.

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 implies when to use it (checking whether Claude/OpenAI/etc. are up) but never says when not to use it or how it differs from the sibling ai_availability, leaving the agent to infer the division of labor.

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