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

Annotations already cover safety properties: read-only, idempotent, non-destructive, and not open-world. The description adds useful behavioral context that the service is 'live' and that forecast values are time-sensitive, but it does not mention authentication, rate limits, caching, or data freshness expectations beyond that single phrase.

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 two short sentences with no wasted words. The primary purpose is front-loaded, and the time-sensitivity note follows as useful context.

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 tool with three required parameters, zero schema descriptions, and no output schema, the description is too thin. It identifies the general concept but omits parameter formats, return value shape, and any guidance about the live service's behavior or freshness.

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% for all three required parameters. The description implies location via 'location-aware' and crop identity via 'crop calendar,' but it does not explain the lat/lon conventions, expected crop_id format, or where crop_id values come from. This leaves parameter semantics substantially under-specified.

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 uses a specific verb, 'Return,' and names the resources: Abyar crop calendar and weather alerts. It also clarifies the result is location-aware and sourced from the live calendar service. It does not explicitly distinguish itself from sibling tools such as abiyar_chill_profile or abiyar_variety_fit, but its purpose is clear.

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?

The description gives no guidance on when to use this tool versus alternatives, nor does it state exclusions or prerequisites beyond noting that forecast values are time-sensitive. An agent must infer usage from the tool name and parameters.

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