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 useful context beyond that: the filterable dimensions and the shape of each returned record (action type, effective date, lots and vessels involved), plus the underlying GET endpoint. Pagination behavior is left to the schema rather than repeated here.

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 tight sentences plus the endpoint reference. The umbrella scope lands first, the record shape second, and the sibling routing last — no filler.

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 14-parameter list tool with no output schema, the description supplies the missing return-shape signal (action type, effective date, involved lots and vessels) that the schema cannot convey. The remaining gap is minor: how the many concurrent filters combine and how pagination continues is only in the schema.

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 one of the 14 parameters is already documented at the field level. The description echoes the filter dimensions (type, state, reference number, dates) but adds no syntax, precedence, or semantics beyond what the schema states, 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?

States a specific verb+resource (work history across all action types) and enumerates the concrete action kinds covered (additions, analyses, transfers, racking, blending, bottling, fruit receiving). It also explicitly distinguishes itself from the typed sibling list tools, so an agent can choose without opening schemas.

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?

Explicitly routes the agent to 'the typed list tools' when full detail of a single action kind is needed, which cleanly separates it from innovint_list_addition_actions, innovint_list_analysis_actions, etc. It lacks an explicit 'when not to use' (e.g. cross-winery or bulk export), but the context is otherwise clear.

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