agri_food_price

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

The description implies a read-only data retrieval operation by referencing the 'FAO Food Price Index' and 'trends', but it does not explicitly state that no modifications are made. With no annotations, the burden is on the description to confirm safety; it partially meets this but lacks details on data freshness or limits.

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 a single, concise sentence that immediately communicates the tool's domain (FAO Food Price Index) and scope (global commodity trends). Every word is meaningful, and no extraneous information is present.

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 lack of parameters, output schema, and annotations, the description is adequate but minimal. It does not explain what the output looks like (e.g., a number, table, or time series) or how it might be used. Sibling tools often have similarly brief descriptions, so it meets minimal expectations but could be more informative.

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, so the schema is fully covered (100%). Per guidelines, the baseline is 4. The description does not need to add parameter info, and it correctly implies no inputs are required, but it could mention that no filters are available.

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 provides the 'FAO Food Price Index' and 'global food commodity price trends', which distinguishes it from sibling agricultural tools like agri_crop_health that focus on crop conditions rather than prices. However, it lacks specificity on what exactly is returned (e.g., current index value, historical trends).

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 on when to use this tool versus alternatives. There are no mentioned use cases, prerequisites, or comparisons to other siblings that might offer price data (such as trade or commodity tools). The description is purely factual without contextual advice.

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