CS_FluorLine

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

The description adds that the output is in cm2/g, which is useful. However, with no annotations and no mention of side effects or state changes, it does not fully disclose behavioral traits. Since it is a calculation tool, 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.

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

The description is concise with no redundant phrases. It uses a clear header for the purpose and a list for parameters. The structure is efficient, though the parameter list could be slightly more compact.

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 large number of sibling tools focusing on fluorescence lines, the description fails to provide context about when this specific tool is appropriate (e.g., which model or database it uses). The existence of an output schema partially mitigates the need for output format description.

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?

Despite 0% schema coverage, the description provides meaningful details for each parameter: Z's integer range (1-120), line with examples ('KL3_LINE', 'KA_LINE', 'LA1_LINE'), and E's unit (keV). This compensates for the schema's lack of descriptions.

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 fluorescence line cross section in cm2/g, specifying the exact physical quantity and units. It distinctly separates from sibling tools like CS_FluorShell (which is for shells) and CS_FluorLine_Kissel (which 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 the many similar siblings (e.g., CS_FluorLine_Kissel, CSb_FluorLine). The description does not mention any prerequisites, limitations, or compare with alternatives, leaving the agent to guess the appropriate selection.

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