faostat_get_report_headers

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

No annotations are provided, so the description carries the full behavioral burden. It conveys only that this is a read-style metadata lookup; it says nothing about whether the payload requires a report identifier, auth requirements, rate limits, or failure modes. That is thin for a tool with a required opaque object parameter.

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?

One front-loaded sentence with zero filler, and the purpose is stated immediately. It is perhaps terse given the unexplained required object parameter, but nothing in it is wasted.

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?

An output schema exists, so return values need not be described. But for a tool whose only required input is an undescribed nested object and which has no annotations, the description omits the request-shape information an agent needs to actually invoke it correctly.

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% and the required 'payload' is an opaque object with additionalProperties=true, so the schema provides no semantic help. The description mentions 'a report' but never explains what belongs in payload or what 'lang' does, leaving the caller to guess the request shape.

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 and resource: 'Get the column headers/schema for a report.' It also distinguishes itself from the data-fetching sibling by noting this happens 'before fetching its data,' though it never names faostat_get_report_data 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?

The phrase 'before fetching its data' implies a workflow position (call this first, then fetch), which is useful implied guidance. However, it names no alternative tool and gives no when-not-to-use condition, so an agent must infer the pairing with faostat_get_report_data.

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