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 elsewhere. The description adds nothing beyond the raw endpoint path — no note on pagination behavior, result ordering, or what a read-only grower list contains.

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 sentences with no filler; the resource description is front-loaded. The trailing HTTP path is slightly redundant given the tool abstraction but is compact and occasionally useful to API-aware agents.

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?

A read-only, fully documented four-parameter list endpoint with no output schema does not demand much, and the schema carries pagination and filtering detail. Still, the description omits any sense of what is returned or how results are ordered, leaving an agent to infer the response shape entirely.

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%, with id filtering, limit range and default, offset semantics including 'next_offset', and winery_id format all documented inline. The description contributes no parameter meaning beyond the schema, so the baseline of 3 applies.

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 names the resource ('the growers the winery buys fruit from') and the underlying GET endpoint, so the retrieval intent is inferable. However, it never uses a verb like 'list' and offers no differentiation from siblings such as innovint_list_vendors or innovint_list_grower_receipts, leaving the agent to lean on the title.

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 statement of when to use this tool versus alternatives, no exclusions, and no prerequisites in the description itself. The only routing hint (use innovint_list_wineries for winery_id) lives in the schema, not the description.

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