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

The readOnlyHint annotation already establishes this is a non-mutating read, so the description is not carrying the safety burden. It adds the concrete API route (GET /status_pages/{subdomain}/services/{service_id}/status), which confirms the read semantics and path shape, but says nothing about return content, freshness, or caching.

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?

Two short sentences with the purpose front-loaded and no filler. The trailing endpoint reference is somewhat redundant with the name and schema but is compact enough to be tolerable.

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?

With no output schema, the description would ideally say what 'current status' contains (state, uptime, incident linkage). It stops at the endpoint, leaving the response shape for the agent to discover. Adequate but with a clear gap for a status-retrieval tool.

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%, with both subdomain and service_id documented in the schema, so the baseline is 3. The description adds only that the lookup is 'by its id'; it does not explain the subdomain override behavior already noted in 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 (Get) and resource (the current status of a single service) scoped by id, which sets it apart from the fleet-level siblings such as statuspal_list_services. It does not explicitly distinguish itself from statuspal_get_status, so the sibling differentiation is only implied.

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 phrase 'a single service by its id' implies the case where you already have a service_id, and by contrast implies statuspal_list_services is used to discover ids. However, there is no explicit when-to-use statement or named alternative, and the overlap with statuspal_get_status is left unaddressed.

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