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

Annotations already declare readOnlyHint=true, openWorldHint=true and destructiveHint=false, so the safety profile is covered. The description adds only the raw endpoint path; it does not say whether multiple filters combine with AND, what the default page size/result cap is, or whether the list is truncated.

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?

Three short sentences, zero padding, front-loaded with what the tool returns before the filtering guidance and the endpoint. Every clause carries information an agent can act on.

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 output schema, enumerating the returned fields is the right compensating move, and all 10 parameters are optional and schema-documented. What's missing is pagination guidance (max/first interaction, default page size) for a list endpoint that can return large result sets.

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 100%, so every parameter is already documented with types, patterns, enum values and defaults. The description restates the filter dimensions at a higher level without adding syntax, combination rules, or pagination semantics beyond the schema.

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?

States a specific verb and resource ("List sales orders") and enumerates the returned fields (customer, status, price list, line items, totals, invoice date), so the agent knows exactly what comes back. The list-vs-get distinction from vintrace_get_sales_order is only implicit in the naming rather than called out.

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 filtering sentence ("Filter by status, customer, order date range or invoice date range") implies when the tool is appropriate, but never states when to prefer vintrace_get_sales_order for a single order or what happens with no filters applied. Usage is inferable rather than prescribed.

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