Create Company Exchange Rates

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

Annotations show readOnlyHint=false and destructiveHint=false, which are consistent with a creation operation. The description adds behavioral context: it returns the created object on success with HTTP 201. This goes beyond annotations, though it does not discuss side effects or error conditions.

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 front-loaded with purpose and includes key details like required parameters and endpoint. It is slightly repetitive (two sentences about creating), but overall concise with 4-5 sentences.

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?

The description covers purpose, return value (created object with HTTP 201), and endpoint. However, it lacks explanation of the exchange_rates parameter format and potential error responses. For a tool with no output schema, more context would be beneficial.

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 coverage is 100%, so baseline is 3. The description lists the three required parameters but adds minimal new meaning beyond what the schema already provides (e.g., 'URL path parameter' for company_id is already in schema). No elaboration on the structure of exchange_rates array.

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 verb 'create' and the resource 'company exchange rates' or 'Currency Configurations'. It provides the specific endpoint and required parameters. However, it does not differentiate from the sibling tool 'create_company_currency_configuration', which overlaps in concept.

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 says 'Use this to create a new Currency Configurations' and lists required parameters, but does not explicitly state when to use this tool versus alternatives like 'get', 'update', or 'create_project_exchange_rates'. No when-not-to-use guidance is provided.

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