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

With no annotations, the description carries the full behavioral burden, and it only hints that data is 'current'. It does not disclose that this is a read-only lookup, the reporting cadence/source (weekly NASS), whether history is excluded, or how defaults (CORN/US) are applied.

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 front-loaded sentence with no filler; the resource and the returned metrics are stated immediately and every clause earns its place.

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 two-optional-parameter read tool with full schema coverage and no output schema, the description is nearly sufficient. The remaining gap is the absence of any note on recency/cadence or how to choose between this and the condition/stats siblings.

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 both parameters are already documented with defaults and accepted values in the schema. The description adds no parameter-level detail (e.g., accepted commodity/state codes) beyond that, 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?

States a specific verb (Get) and resource (NASS crop progress) and clarifies the payload with metric examples ('% planted, emerged, harvested, etc.'). It is distinguishable from get_crop_condition (ratings) and get_crop_stats (aggregate stats), but it never names or contrasts those siblings explicitly.

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?

No when-to-use guidance and no alternatives named, despite several adjacent siblings (get_crop_condition, get_crop_stats, and the *_history tools). The word 'current' implicitly scopes it to the latest report, but the agent gets no explicit routing instructions.

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