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

Annotations are absent, so the description must disclose behavioral details such as read-only nature, result limits, ordering, and the meaning of 'newly.' The description only says it gets wells and gives a few output fields; it does not mention limit behavior, pagination, or how 'newly' is defined.

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 sentence front-loads the action and scope, then adds one useful use-case clause. There is no filler or redundancy, and every clause adds context about what the resource or purpose is.

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 two-parameter read tool, the description covers the main query and returned fields, but without an output schema or annotations it leaves important gaps: the definition of 'newly,' how limit applies, and the exact shape of the result. It is adequate but not fully self-sufficient.

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%, so the description must explain both parameters. It covers the state parameter through 'Texas or Oklahoma' but never explains the 'limit' parameter or whether fields like operator/county/formation are return columns vs filters.

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 identifies the verb ('Get'), the resource ('wells that newly began producing'), the geographic scope (Texas or Oklahoma), and expected fields. It is specific enough to distinguish from siblings like get_recently_spudded_wells, but it does not explicitly name the alternatives or contrast them.

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 guidance is given about when to prefer this tool over alternatives such as get_top_producing_wells or get_recently_spudded_wells. The phrase 'leading indicator of fresh royalty income' implies an audience, but it does not state when to use it or when not to use it.

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