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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so safety is covered. The description adds only the raw REST path, which conveys nothing about pagination behavior, result ordering, or error conditions beyond what the schema and annotations already state.

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 clauses, front-loaded, nothing padded. The endpoint URL is marginal value for an agent but costs little and does anchor the response shape.

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?

No output schema exists, so the description is the only place an agent can learn what is returned — additive names, amounts, units, application dates, or whether entries are paginated objects. It says none of this, leaving the response shape entirely unknown.

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% and the schema itself explains all four parameters, including that offset should come from the previous reply's next_offset. The description adds no parameter meaning on top of that, so the baseline 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 fragment 'Additives that have been added to a lot' identifies the resource and its scope (per-lot), which does imply a listing. But it is a noun phrase rather than a verb+resource statement, and it never distinguishes this from the sibling innovint_list_additives (winery-wide additive catalog), which an agent could easily confuse.

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 call this versus innovint_list_additives, innovint_list_addition_actions, or innovint_get_lot_composition. No prerequisites, no exclusions, nothing beyond the resource statement.

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