Get OPEC Production

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

Annotations already provide readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds meaningful context: an eligible account entitlement is required, results are country-level, and the API response is authoritative. It does not specify units or data availability nuances, but for a zero-parameter read tool this is strong.

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?

Five short sentences, each earning its place: core purpose, usage triggers, return content, entitlement prerequisite, and fallback guidance. The information is front-loaded and there is no filler.

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 zero-parameter, read-only data lookup, the description covers what the tool returns, when to use it, what precondition exists, and where to route access questions. No output schema exists, but the essential return information is present.

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?

The tool has zero parameters and the schema coverage is 100%, so the description has no parameter burden. The 0-parameter baseline applies, and the description adds no misleading or unnecessary parameter detail.

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 opens with a specific verb and resource: 'Get the latest OPEC oil production data.' It clarifies the data product as country-level production figures, which distinguishes it from siblings like opa_get_price or opa_get_rig_counts.

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?

It explicitly states when to use the tool: 'Use when the user asks about OPEC output, production quotas, supply cuts, or OPEC+ compliance.' It also points to opa_get_plans for access and pricing questions, giving clear routing to an alternative.

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