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

Annotations declare readOnlyHint=false and destructiveHint=false, so the agent knows this is a non-destructive mutation, but the description adds no behavioral context of its own. It does not say whether pausing is reversible, whether the pause has a duration, whether in-flight deliveries are stopped, or whether the alert's history is preserved.

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 single short sentence is front-loaded and free of padding, but this is under-specification rather than true conciseness; there is room for one clarifying clause at no cost to brevity.

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?

The tool is structurally simple (one required integer, no nested objects, no output schema), yet a mutation tool with a 0%-documented parameter and no return information leaves the agent without enough to call it confidently or predict its effect.

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 0% on the single required parameter alert_id, and the description supplies nothing about where the ID comes from, its format, or what happens if it refers to an already-paused or nonexistent alert. The description therefore does not compensate for the schema gap.

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?

"Pause an active alert." gives a verb and a resource, but it is nearly a restatement of the title "Pause Alert" and adds only the qualifier "active." It does not distinguish this reversible pause from the sibling delete_alert, which is the most consequential ambiguity for an agent choosing among alert tools.

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?

No when-to-use guidance is given: nothing says to prefer this over delete_alert when an alert should be temporarily silenced versus permanently removed, and nothing states the prerequisite that the alert must currently be active.

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