Azure Cost Alerts

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

With no annotations provided, the description carries the transparency burden. The verb 'Lists' clearly implies a read-only operation. It adds context about the types of alerts and the WAF purpose. While it doesn't mention pagination, auth, or side effects, for a list tool the description effectively conveys non-destructive 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?

Two sentences, front-loaded with the core function, then a relevant WAF context and sibling compliment. Every sentence earns its place, with no redundant phrasing.

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 single-parameter list tool with no output schema, the description is remarkably complete. It covers what alerts are returned, the scope, a usage scenario, and the relationship to a sibling tool. No critical gaps for an agent to invoke correctly.

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 the scope parameter is fully described in the schema. The description adds no additional parameter-level detail, sticking to the baseline of 3 for high schema coverage.

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 clearly states the tool lists active cost alerts for a scope, enumerating alert types (budget breaches, credit warnings, quota violations, anomalies). It uses a specific verb+resource+scope structure and distinguishes itself from sibling azure_budget_list by focusing on alerts rather than budgets.

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 provides a clear use case: 'monitor alerts to detect unexpected cost spikes before they escalate.' It explicitly recommends complementing with azure_budget_list to correlate alerts with budget thresholds. It does not explicitly state when not to use it, but the context and sibling reference give adequate guidance.

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