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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered; the description adds genuine value beyond that by explaining what an alert actually represents (escalation-rule output for serviced accounts), the default filter state, and that each alert carries a human-readable message. It stops short of describing pagination or result volume behavior.

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?

Three compact sentences that front-load the resource definition before the filtering behavior and the return-content note. Dense but every clause carries information; no filler or repetition.

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 correctly notes alerts carry human-readable messages, and it covers status semantics, but it omits the `limit` pagination parameter and the meaning of company_id. For a zero-required-param listing tool this is adequate but leaves real gaps an agent would want filled.

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 3 parameters, so the description must compensate and only partly does: it maps the status enum values and states the default (open), but leaves limit and company_id entirely unexplained beyond the loosely implied 'for a partner account' scoping.

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 specific verb and resource with scope: the partner account's maintenance 'needs attention' inbox, defined as alerts opened by escalation rules for serviced accounts, with concrete examples (problem thresholds, printers out of order too long, overdue jobs, visits due). This is distinguishable from siblings like list_maintenance_problems and get_partner_maintenance_overview without opening either schema.

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 description establishes the default behavior ('Open alerts by default') and enumerates the status filter options, which is useful invocation context. However, it never says when to choose this tool over list_maintenance_problems, list_maintenance_visits, or get_partner_maintenance_overview, so alternative selection is left to inference.

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