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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds only that retrieval is keyed by noteId, and says nothing about return content, not-found behavior, or access requirements, so it contributes little beyond the structured fields.

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?

A single compact sentence with the lookup key front-loaded and no filler. It is efficient, though the brevity borders on under-specification rather than true conciseness.

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 simple single-record getter with no output schema or nested objects, the description is minimally adequate: the agent knows what it retrieves and by which id. However, with two undocumented parameters and no return/error context, it leaves gaps an agent may need to fill.

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 0%, so both farmId and noteId are undocumented in the schema. The description mentions noteId only as a lookup key and never explains farmId or the relationship between the two, so it does not compensate for the coverage gap.

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 gives a specific verb ('Get') and resource ('Farm Note') scoped to a single record ('one ... by noteId'), which cleanly distinguishes it from list_farm_notes. It does not explicitly name the sibling alternatives (list/create/update/delete_farm_note), so it falls short of a 5.

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 guidance on when to use this versus list_farm_notes, nor any prerequisite or error condition mentioned. The only implied usage is the presence of a noteId in hand.

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