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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so safety is covered. The description adds genuine value by disclosing the underlying endpoint (GET /alerts) and the content of each alert (type, severity, title, message), though it omits pagination behavior beyond the schema.

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 the field list and endpoint appended; no filler and nothing redundant.

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 helpfully enumerates the returned fields, which is the main thing an agent needs to know. The only gap is that pagination is left entirely to the schema, which is acceptable given full coverage there.

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% and the single page parameter is already documented with default, bounds and next_page guidance. The description adds nothing about parameters, 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?

Names a specific verb (list) and resource (active alerts and system messages) plus the dashboard scope and returned fields. No sibling tool overlaps with alerts, so no differentiation is needed, but it stops short of the 5 mark because it doesn't explicitly state that only active/current alerts are returned versus historical ones.

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?

Implied usage only: the mention of 'shown on the Sellasist dashboard' hints at the context an agent would use it in, but there is no explicit when-to-use, when-not-to-use, or alternative guidance. For an alerts listing this is largely self-evident, keeping it at minimum viable.

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