get_apirro_pricing

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

No annotations are supplied, so the description carries the full burden. It partially discharges that by disclosing the actual content returned (Free Trial, Discovery, Activate, Enterprise), which is valuable given there is no output schema. It does not state that this is a static, safe read with no arguments, but for a zero-param lookup the residual risk is minimal.

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?

A single front-loaded sentence with no filler; the resource is stated first and the enumeration of tiers adds concrete value rather than padding.

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 params, no annotations and no output schema, the description must convey what comes back — and it does by naming the tiers. It would be fully complete if it noted the data is static/current only, but for a simple lookup this is close to sufficient.

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?

The tool takes zero parameters, so there is nothing to document and the baseline of 4 applies. The schema is empty and the description correctly introduces no spurious parameter concepts.

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 names the exact resource (Apirro pricing tiers) and enumerates the specific tiers returned, so an agent knows precisely what it gets back. It is a noun phrase rather than a verb+resource construction, but the intent is unambiguous and clearly distinct from siblings like scan_agent_readiness or get_agent_link_details.

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?

There is no statement of when to use this tool versus alternatives. With seven siblings including search_apirro_resources and get_agentic_commerce_overview, the description gives no routing signal — though for a zero-parameter static lookup the usage is largely self-evident.

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