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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds useful context that results are org-scoped and sorted newest-first, but says nothing about pagination, truncation at the limit, or what happens when status='any'.

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 filler; scope and ordering are stated immediately and nothing is repeated from the structured fields.

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 zero-required-param read-only list tool with full schema coverage this is close to adequate, but with no output schema the description could usefully sketch what an alert record contains or note pagination behavior. Ordering is the only return-value hint provided.

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%, so every parameter including defaults (limit=100, status=active, since_hours=168) is already documented in the schema. The description adds no parameter-level meaning such as filter interaction or severity values, 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?

States a clear resource (alerts), scope (this organization's agents), and ordering (newest first), which is enough to distinguish it from the agent-oriented siblings list_agents and get_agent. It does not explicitly name those siblings or contrast itself with them, so it stops short of a 5.

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?

There is no when-to-use guidance, no mention of alternatives such as get_fleet_summary for aggregate health, and no exclusions or prerequisites. The agent must infer from the name alone that this is the tool for retrieving alert rows.

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