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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=false, and the pause/resume framing is consistent with a non-destructive status flip. However, the description adds nothing beyond the annotations: no confirmation that this is reversible, no permission requirements, no side effects on active leads or deliveries.

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 short sentence with the action front-loaded and no filler. It is efficient, though its brevity is also the source of the coverage gaps rather than a sign of completeness.

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 mutation touching four required identifiers with no output schema and no parameter documentation, the description is too thin. It should at least clarify what ruleId/siteId/projectId refer to and whether the status change is immediately effective.

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% and all four parameters (projectId, siteId, ruleId, status) are required but wholly undocumented in both schema and description. The 'pause or resume' wording loosely maps to the status enum, but the three identifier parameters get no explanation of what they must reference.

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 pair ('pause or resume') and resource ('alert rule'), making the operation understandable in isolation. It doesn't distinguish itself from siblings like create_lead_alert_rule, delete_lead_alert_rule, or list_lead_alert_rules, and the title's fuller 'lead alert rule' phrasing is trimmed to 'alert rule'.

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 guidance on when to pause versus resume, no prerequisites, and no routing to alternatives such as delete_lead_alert_rule or list_lead_alert_rules. The agent must infer usage entirely from the name and enum values.

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