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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The description adds the temporal nuance that composition can be as-of-now or as-of-after-an-action, but says nothing about pagination, size, permissions, or what the composition payload 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, front-loaded with the purpose. The raw endpoint path is low-value filler for an agent that already has the schema, 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?

No output schema exists, so the description carries the burden of describing what a 'composition' returns (components, quantities, percentages?) and does not. For a read tool with three simple params this is workable, but an agent cannot predict the response shape.

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 lot_id, winery_id and after_action are already fully documented with examples. The description's 'right after a given action' merely echoes the after_action schema text, adding no syntax or edge-case meaning.

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 the resource and the concept being fetched ('the lot's makeup composition (what it is made of)'), disambiguating an unusual domain term. It does not, however, distinguish this from the close sibling innovint_get_lot_components_summary, so an agent could still confuse the two.

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?

The phrase 'now or right after a given action' implies when to supply after_action, but there is no explicit when-to-use vs. when-not, and no mention of the components_summary or get_lot siblings as alternatives.

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