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

No annotations are provided, so the description carries full burden. It does not explicitly state that this is a read-only or non-destructive operation, though the name 'get_pricing' strongly implies it. The description also doesn't hint at any rate limits, response formats, or potential errors. However, for a simple pricing lookup, the behavioral surface 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?

The description is a single, well-structured sentence that immediately states the tool's purpose. No unnecessary words; every word adds value.

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?

Given that the tool has zero parameters and no output schema, the description is nearly complete. It identifies the product areas (offboarding export and compliance API) that pricing covers, which is the main information an agent needs to decide to invoke it. A minor gap is the lack of an explicit statement about what the response looks like, but this is not critical for a simple pricing lookup.

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 has zero parameters, so the input schema is empty. The description adds no parameter-specific detail, but none is needed. Baseline for zero-parameter tools is 4, which is appropriate here.

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 returns pricing for two specific MyDataPass offerings: the offboarding export and the compliance API. The verb 'get' plus the specific resource makes the purpose unambiguous and distinguishes it from sibling tools that cover other topics like guides or certificates.

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 implies this tool is used when pricing information for those specific offerings is needed. While no explicit alternatives are mentioned, the sibling tool names (about_mydatapass, check_compliance_requirement, etc.) clearly cover different purposes, so the usage context is evident.

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