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 returned field set (amount, cost, date, feed type, inventory used), which is useful, but says nothing about pagination behavior, ordering, or empty-result semantics beyond what the schema's page/limit descriptions already state.

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 what the record contains and followed by the exact endpoint shape. Nothing is wasted and the reader gets the core fact in the first few words.

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 compensates by enumerating the returned fields, which is exactly what an agent needs to decide whether to call this. Pagination and id constraints are fully covered by the schema; only ordering and result-shape details are missing, which is minor.

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 all four parameters (including the animals/livestock_groups enum and the pagination fields) are already documented in the schema. The description only echoes 'one animal or livestock group', adding no syntax, id format, or pagination guidance beyond the schema, so the 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 names a specific resource (feeding records), its scope (one animal or livestock group), and even the REST endpoint, so the agent can immediately tell what is returned. It does not explicitly contrast with the write sibling farmbrite_create_feeding, but the read intent is unambiguous from 'records' plus the GET path.

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 only implied: the parent/parent_id requirement makes clear it lists feedings for a single animal or group, and the endpoint notation reinforces that. There is no explicit 'use this when…' guidance, no exclusions, and no pointer to the sibling that creates feedings versus this one that lists them.

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