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

No annotations exist, so the description carries the burden. It states 'Returns' indicating a read operation, but does not explicitly confirm idempotence or absence of side effects. It mentions data frequency and source but lacks details on limits, caching, or authentication needs.

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 focused sentences. The first clearly identifies the tool's purpose and source; the second lists outputs and uses. No extraneous information, efficiently front-loaded.

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?

Given the presence of an output schema and well-documented parameters, the description covers purpose, source, variables, and use cases adequately. Minor omission: temporal data range or update frequency could be mentioned, but overall sufficient for a data retrieval tool.

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 baseline is 3. The description adds context about returned variables but does not enhance understanding of parameters beyond what the schema provides (e.g., coordinate system, date format). No extra parameter guidance.

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 clearly states it returns daily solar irradiance and climate variables from NASA POWER for any coordinate. It lists specific variables and use cases, distinguishing it from siblings focused on other environmental data.

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 implies usage through use cases (solar siting, agriculture, climate analysis) but does not explicitly state when to use this tool over alternatives or when to avoid it. No exclusions or sibling comparisons are provided.

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