azure_estimate_architecture_cost

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

No annotations are provided, so the description carries the burden of behavioral disclosure. It conveys that this is a compute/estimate operation rather than a mutation and adds the behavioral detail 'Resolves prices in parallel.' However, it does not disclose response shape, auth requirements, or failure 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?

The description is two short sentences with the primary purpose front-loaded. The parallel-resolution note is minor but not wasteful, making the definition appropriately concise.

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 four top-level parameters, nested component objects, no annotations, and no output schema, the description is too high-level. It omits guidance on required SKU/region inputs, reservation vs consumption pricing, currency handling, and response format selection.

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 the description adds no parameter-level meaning. It does not explain the components array requirements, priceType, currency, response_format, or includeReservationAlternative, so it fails to compensate for the low 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 states a specific verb ('Estimate') and resource ('multi-component Azure architecture') with a clear monthly/annual scope. This differentiates it from sibling tools focused on single price lookups, VM comparisons, actual cost queries, or 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 clear context: use when an aggregate monthly/annual cost estimate for a multi-component Azure architecture is needed. It does not explicitly name alternatives or exclusions, so it stops short of full routing guidance.

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