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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint, so the safety profile is fully covered without the description. The description adds that the response includes all updates and affected components, which is useful given there is no output schema, but says nothing about behavior for unknown/invalid incident IDs or any rate limiting.

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?

One front-loaded sentence with no filler; the payload contents are appended after the core action, which is the right ordering. Nothing could be removed without losing information.

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 single-parameter read tool with no output schema, the description covers purpose and what the response contains, which is the main gap it needed to fill. The only missing piece is how to obtain a valid incident_id and what happens on a missing incident.

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 parameter carries its own description ('The incident ID to retrieve details for'), so the schema does the heavy lifting. The description adds no format, source, or example detail for incident_id beyond what is already structured.

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 ('status page incident') with scope qualifiers ('a specific', as opposed to a list), so it is distinguishable from list_statuspage_incidents. It does not explicitly name the sibling, but the singular/plural contrast is clear enough.

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: 'a specific incident' suggests the agent must already have an identifier, which in practice comes from list_statuspage_incidents, but the description never says so. There is no explicit when-to-use, when-not-to-use, or prerequisite guidance.

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