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

With no annotations provided, the description carries full burden. It adds valuable behavioral context by disclosing what data is returned (spend vs limit, forecast, overage risk), compensating for missing output schema. However, it lacks operational details like permission requirements, Azure subscription scoping, or whether this triggers any notifications/alerts.

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?

Single dense sentence with action-front-loaded structure ('Check Azure budget status:'). The colon-separated list efficiently communicates four distinct data points returned. No filler words or redundant explanations. Every token earns its place.

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 simple 1-parameter tool with 100% schema coverage but no output schema, the description adequately compensates by detailing the conceptual return values (spend, limits, risk). Missing explicit error handling or subscription scoping details that would be necessary for a 5, but sufficient for agent selection and basic invocation.

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 has 100% coverage with the single 'provider' parameter already documented as 'Cloud provider to query'. The description reinforces the Azure constraint by explicitly mentioning 'Azure budget status' in the text, but does not add semantic depth beyond what the schema and const value already specify. Baseline score appropriate 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?

Description uses specific verb 'Check' with clear resource 'Azure budget status' and enumerates specific metrics returned (current spend vs limit, percentage used, forecast, overage risk). This clearly distinguishes it from siblings like get_cost_summary (general costs) or detect_anomalies (pattern detection) by focusing on budget limit adherence and overage risk.

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 explicit when-to-use or alternative recommendations provided. However, the specific metrics listed (percentage used, overage risk) implicitly signal this is for budget monitoring and limit compliance checks, distinguishing it from general cost analysis tools. Agent must infer appropriate use cases from output descriptions.

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