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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds useful context by saying the profile is 'live' and comes from 'Matrix and DB,' but it does not describe not-found behavior, permissions, or response characteristics. It does not contradict the annotations.

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?

The description is a single front-loaded sentence with the verb 'Read' and the resource 'Abyar crop/cultivar profile' stated immediately. It contains no filler or redundant phrasing.

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 one-parameter read operation, the annotations cover safety and idempotency, and the description supplies the data-source context. However, it omits meaningful detail about the crop_id parameter and does not explain return or error behavior despite there being no output schema. It is adequate but incomplete.

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%, and the only parameter, crop_id, has no description beyond a string pattern. The description mentions 'crop/cultivar profile' but does not clarify whether crop_id is an internal Abyar identifier, a cultivar code, or what format it should take. With low schema coverage, the description should compensate but does not.

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 states a specific verb and resource: 'Read one live Abyar crop/cultivar profile.' It also identifies the data sources as 'Matrix and DB,' making the operation clear. It does not explicitly distinguish itself from sibling tools such as abiyar_get_taxonomy, 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 explicit guidance on when to use this tool versus alternatives like abiyar_get_taxonomy or abiyar_describe. The retrieval-by-ID usage is implied by the name and description, but no conditions, exclusions, or alternatives are stated.

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