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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds the underlying REST path (GET /api/v1/wineries/{wineryId}/growerReceipts/{vintage}), which helps map to the API but reveals nothing extra about auth, rate limits, or result shape. Pagination behaviour is left entirely to the schema's offset description.

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?

Two short, front-loaded sentences with no filler; the resource and scope come first. The raw endpoint path is arguably redundant with the tool name but is compact and not distracting.

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, the description does not say what a receipt record contains or whether results are paginated, though the offset parameter implies paging. For a simple read-only list endpoint with fully documented params and safety annotations, this is adequate but not complete.

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 limit, offset, vintage and winery_id are all documented in the schema itself, including the next_offset paging hint. The description only restates that vintage is a year, adding nothing beyond the schema baseline.

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 resource ('Fruit receipts from growers') scoped to one vintage, so an agent can tell it apart from innovint_list_growers or innovint_list_receive_fruit_actions. The verb is only implied (list) from the name rather than written out, but the object and scope are unambiguous.

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 over the sibling list tools (growers, receive fruit actions), nor any prerequisite note beyond the required winery_id and vintage. An agent must infer applicability from the resource name alone.

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