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 that this is a GET over a parent-scoped subresource and lists which fields come back, but says nothing about paging through results or result ordering.

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: what a note contains and where notes hang. Scope is front-loaded and nothing is redundant.

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?

With no output schema, the description usefully enumerates the returned fields (description, category, date, keywords), which is the main thing an agent needs. The remaining gap is paging behavior, which is at least documented in the schema's page/limit descriptions.

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 coverage is 100%, so the baseline is 3, but the description adds real value by mapping the enum tokens to domain concepts ('plots' = field, 'plants' = plant type, 'crops' = crop planting, 'inventory_types' = inventory type), which an agent would otherwise have to guess. Page and limit semantics remain schema-only.

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 the resource (notes) and its attachment scope (animal, field, plant type, crop planting, inventory type), plus the underlying GET endpoint, so the agent can tell it apart from farmbrite_create_note. It stops short of explicitly contrasting with the write sibling, but the retrieval intent is unmistakable.

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?

Usage is implied: call it when you need the notes on a known parent record. There is no explicit when-to-use statement, no mention of the create_note alternative, and no note about pagination or repeated calls being needed to gather all notes.

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