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 the GET endpoint path, which is mild extra context, but says nothing about pagination defaults, archived handling, or response shape beyond what the schema states.

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?

Three terse fragments with no wasted words, but the clipped noun-phrase style reads as under-specification rather than disciplined conciseness. The endpoint string consumes space without adding agent-relevant meaning.

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 read-only list tool with full schema coverage and no output schema, this is minimally viable: filters and pagination are documented in the schema. What is missing is the routing information an agent needs to pick this over innovint_list_vineyards or other list_* siblings.

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%, including detailed docs for limit, offset, archived, vineyard_in and id_in, so the schema carries nearly all parameter meaning. The description's only contribution is the 'filter by vineyard' hint, matching the existing vineyard_in description. 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 description identifies the resource (vineyard blocks belonging to the winery's vineyards) and the endpoint, but it is a noun fragment rather than a verb+resource statement, so the 'list' action comes only from the title/name. It does partially distinguish scope from innovint_list_vineyards by saying these are blocks of vineyards, but the distinction is implicit.

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?

'Filter by vineyard' hints at using vineyard_in but gives no when-to-use guidance, no exclusions, and no reference to siblings like innovint_list_vineyards or innovint_get_lot. An agent is left to infer pagination and archived-record behaviour entirely from the schema.

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