Behavior2/5

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

With no annotations, the description should fully disclose behavior. It mentions the parameter range for Z (1-120) and provides transition examples, but does not describe side effects, performance, or assumptions. The tool's read-only nature is implied but not explicit.

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

Conciseness4/5

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

The description is short and front-loaded with purpose, followed by parameter details in a clear 'Args:' format. Every sentence is useful, though the 'Args:' prefix is slightly redundant but not harmful.

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?

The tool has simple inputs and an output schema exists, so the description is somewhat adequate. However, it lacks any explanation of the return value or additional context like units or typical usage, which would help an AI agent fully understand the tool's behavior.

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 0%, so description must compensate. It explains Z as atomic number with range and auger_trans as a transition name with two examples. However, it does not specify the exact format or accepted values beyond the examples, which is a gap for correct invocation.

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

Purpose4/5

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

The description clearly states the tool gets the Auger rate for a given transition, with specific verb 'Get' and resource 'Auger rate'. It lists parameters and examples, but does not differentiate from siblings like AugerYield which might be confusing for an AI, though the name itself provides some distinction.

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

Usage Guidelines2/5

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

No explicit guidance on when to use or not use this tool compared to alternatives like AugerYield or other rate functions. The description lacks context about prerequisites or scenarios, leaving the AI to infer usage from the tool name alone.

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