get_resource_cost_breakdown_azure

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

Discloses that no storage account needed, data is queried live, and it's a team plan feature. No destructive side effects implied. Without annotations, description adequately covers behavior, though return format is not detailed.

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?

Concise with a short summary, structured Args block, and relevant examples. Every sentence serves a purpose; no redundancy.

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?

Covers essential aspects: purpose, parameters, live query, team feature. Missing explicit return structure, but examples imply a list of resources with costs. Adequate given no output schema.

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%, but the description fully explains all 6 parameters with defaults, filtering options, and example usage. Adds significant value beyond schema types/titles.

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?

Clearly states 'Return per-resource Azure cost detail via the Cost Management Query API.' The name and description together specify verb (return), resource (Azure resource cost), and scope (per-resource), distinguishing it from the AWS sibling tool.

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?

Provides clear context: live query without storage setup, multi-subscription support, and team plan feature. Includes example intents. However, no explicit comparison to alternatives or when-not-to-use guidance.

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