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 real value beyond that by describing the payload contents (analyses with type/value/unit, linked lots and vessels), which matters since there is no output schema. It does not mention pagination behavior or whether deleted/edited actions appear by default, which are the remaining gaps.

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 sentences, front-loaded with the entity definition, with no filler prose. The trailing raw endpoint path is largely redundant with the tool contract but is short enough not to hurt.

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 13-parameter read-only listing tool with no output schema, the description does explain the returned data and is backed by complete schema docs and safety annotations. What it lacks is routing context against the many sibling list/get tools and any note on defaults (e.g. action state inclusion, pagination via next_offset), leaving an agent to infer how this differs from adjacent endpoints.

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 all 13 parameters (id, state, date bounds, limit/offset, sort, reference_number, winery_id) are individually documented in the schema with formats, defaults and cross-references. The description adds no parameter meaning of its own, 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 a specific resource (analysis actions = lab and in-house results entered in the winery) and enumerates the content returned (analyses with type/value/unit, plus lots and vessels). It is clear what the tool retrieves, but it never distinguishes this from close siblings like innovint_list_lot_analyses or the generic innovint_list_actions, so an agent cannot tell from the text why it would pick this one.

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 when-to-use or when-not-to-use guidance, no mention of alternates, and no prerequisites beyond the endpoint path. The agent must infer that this is the way to enumerate analysis/lab results per winery, and it gets no help deciding versus list_lot_analyses or list_actions.

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