Invoices_getInvoicesAttributes

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

With no annotations, the description carries more weight and does provide some behavioral context: it is a catalog entry, executes in a Kuudo deployment rather than here, and returns marketplace-dependent results. However, it is vague about what 'not here' means, does not address side effects or auth requirements, and gives no detail on how the schemas and values are delivered.

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 short and front-loaded, with no real verbosity. However, 'Catalog entry' and 'Kuudo deployment' are unexplained jargon that could confuse an agent instead of clarifying the tool's role.

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?

For a zero-parameter tool with no output schema, the description gives a high-level idea of the return value but not the structure of the schemas or the meaning of the execution/environment caveat. An agent still cannot confidently determine whether this tool is callable from the current environment or how the response will be shaped.

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 input schema has zero properties and zero required parameters, so there is little for the description to add. The 0-parameter baseline applies, and the description introduces no parameter confusion, although it also does not clarify the additionalProperties: true allowance.

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 concrete action: it returns marketplace-dependent schemas and their set of possible values, and the tool name ties this to invoice attributes. It does not explicitly say 'invoice attributes' or contrast itself with the other Invoices_* siblings, leaving some disambiguation to the agent.

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 guidance on when to use this tool versus alternatives like Invoices_getInvoices or Invoices_getInvoicesDocument. The line about running in a Kuudo deployment hints at an environment restriction, but it does not explain whether the agent should invoke this tool, ignore it, or route the call elsewhere.

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