CSb_Photo_Total_CP

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

No annotations provided. The description mentions 'using Kissel' but does not disclose other behavioral traits (e.g., return format, energy range constraints, or any side effects). For a tool with zero annotations, more behavioral context is needed.

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 appropriately short and front-loaded with the purpose. The argument list is clear. However, a slightly more structured format could improve readability.

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 simplicity (2 params, no nested objects) and presence of an output schema, the description is adequate but lacks details on return value format or constraints. It is complete enough for a basic calculator tool.

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 input schema has 0% coverage, but the description adds meaning: compound as 'Chemical formula, e.g. SiO2, H2O' and E as 'Photon energy in keV'. This provides examples and units that are not in the schema, compensating well.

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 calculates the total photoionization cross section using Kissel, with a specific verb 'Calculate' and resource 'total photoionization cross section' in barn/atom. This distinguishes from sibling tools like CS_Photo_Total which likely uses a different method.

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 on when to use this tool versus alternatives like CSb_Photo_Total or CS_Photo_Total_CP. The description lists arguments but does not specify context or exclusions.

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