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

Annotations already declare readOnlyHint=true, so the read-only safety profile is covered. The description adds useful behavioral context beyond annotations by disclosing the response composition and update ordering (newest first, with UUIDs).

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 description is a single compact sentence that front-loads the resource and includes the key return details without filler or redundancy.

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 low-complexity single-parameter read tool with no output schema, the description adequately conveys what the response contains: the incident, its updates in order with UUIDs, status pages, and affected components. Nothing essential is missing for correct invocation.

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 uuid parameter is already documented with its format ('inci_...'). The description mentions UUIDs of updates but does not add further meaning to the input parameter itself, 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?

The description states a specific verb and resource: retrieving one status page incident. It also specifies what is included—every update newest-first with UUIDs, status pages, and affected components—which clearly distinguishes it from list_status_page_incidents and create/update/resolve incident siblings.

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 singular phrasing 'One status page incident' combined with the required uuid parameter makes the get-by-id use case clear. It does not explicitly contrast with list_status_page_incidents or other incident tools, so it stops short of a 5.

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