fuel_price_guide

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

No annotations provided, so description carries the burden. It implies a read-only informational tool by mentioning 'prices' and 'trend', but does not explicitly state behavioral traits like read-only, authentication needs, or data source reliability.

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?

Single sentence with no wasted words. Front-loads key information: fuel types and data provided.

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 no parameters and an output schema exists, the description adequately covers what the tool returns. It could mention any prerequisites or limitations, but overall 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?

No parameters in the input schema, so baseline is 4. Description adds meaning by specifying the output content (fuel types, committee info, trend).

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 monthly UAE fuel prices for specific fuel types (Super 98, Special 95, E-Plus 91, diesel) and includes committee mechanism, snapshot, and trend. It distinguishes itself from all sibling tools which cover unrelated topics.

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 implicitly tells when to use (to get fuel price info) but lacks explicit guidance on when not to use or alternatives. Since sibling tools are all distinct, no confusion arises, but it could be more explicit.

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