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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds only the REST path, which confirms the read-only listing nature but says nothing about default state filtering (ACTIVE vs DELETED), pagination behavior, or result size that an agent would want to know.

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 with the substance front-loaded; nothing is padding. The trailing raw endpoint is of marginal value to an agent that invokes the tool rather than the HTTP API, but it costs little.

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 list tool with no output schema, the description says what the records are about but not what a record contains (additive type, rate, unit, timestamps, related lot/vessel ids). An agent knows what to query but not what it will get back.

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 every one of the 13 parameters is documented in-schema, including the pointer to innovint_list_wineries for winery_id and the next_offset convention. The description adds no parameter meaning beyond that, which is the expected baseline when the schema does the work.

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?

Names a specific resource (addition actions) and states its content precisely: which additives were added to which lots and vessels, and when. That content description implicitly separates it from list_transfer_actions or list_analysis_actions, though no sibling is named explicitly.

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 guidance at all. With siblings such as innovint_list_actions, innovint_list_lot_additives and innovint_list_lot_analyses available, the agent must infer whether this is the canonical addition source or a subset of the generic action list.

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