find_parameter_by_name

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

The description notes case-insensitive search, which is helpful. But it does not disclose behavior for no matches or multiple matches, and no annotations are provided. With no annotations, the description could be more thorough on behavioral specifics.

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 a clear summary, usage hint, and parameter list. It includes examples and avoids fluff, though the parameter list could be integrated better.

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?

The description explains parameters and usage well. Since an output schema exists, the lack of output details is acceptable. It covers the core functionality sufficiently for correct invocation.

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?

Schema coverage is 0%, but the description adds meaningful details: explains index base (0-based) and provides examples for name_substring. This adds value beyond the schema's minimal titles.

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 the tool finds a device parameter index by searching a substring in the parameter name. This distinguishes it from siblings like get_device_parameters or set_device_parameter, which serve different purposes.

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 explicitly states it is useful for discovering parameter indices without manual inspection, providing clear context. However, it does not mention when not to use it or alternatives.

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