Read-onlyIdempotent

Compare data egress pricing across OCI, AWS, Azure, and GCP by specifying your monthly outbound data volume in GB.

Instructions

Compare OCI data egress pricing with AWS/Azure/GCP.

Behavior2/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, covering safety. Description adds 'compare pricing' but no additional behavioral traits (e.g., live vs cached data, ation details). Minimal extra value.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, no wasted words, front-loaded with the core purpose. Highly concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simple tool (1 parameter, no output schema), the description sufficiently communicates the tool's purpose. However, it lacks detail on return format or how the comparison is presented, which could be helpful.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with a clear description for 'monthlyGB' parameter. Description does not add further semantics beyond what the schema provides, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the verb 'compare', the resource 'data egress pricing', and the scope across OCI, AWS, Azure, GCP. It distinguishes from sibling tools that handle cost calculations or other comparisons.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implicitly indicates the tool is for comparing data egress pricing across clouds, but does not explicitly provide when-to-use or when-to-use-alternatives guidance. It's adequate but lacks direct usage cues.

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