Set Configuration Operand Value

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

No annotations are provided, so the description carries the full burden. It touches on the two modes (direct value vs pickup solve), which is useful, but says nothing about what a pickup solve does, whether offset/scaleFactor only apply in pickup mode, whether value and pickup parameters are mutually exclusive, or what permissions/state are required.

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?

A single tight sentence with the operation front-loaded and no filler. It is appropriately sized, though very terse for a tool where the two operating modes need clarification.

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?

For a 6-parameter mutation tool with no annotations and no output schema, the description is too thin. It never explains how value/offset/scaleFactor/pickupConfig interact, nor what happens to the cell's existing solve, which an agent needs in order to call it correctly.

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 description coverage is 100%, so all six parameters are already documented (value, offset, operandRow, scaleFactor, pickupConfig, configurationNumber). The description's 'value or pickup solve' hints at the mode distinction that the schema does not resolve, but adds no syntax or interaction detail beyond that. Baseline 3 applies.

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?

States a specific verb ('Set') and resource ('configuration operand cell') with the supported value types (value or pickup solve). It is clear on its own but does not differentiate itself from nearby siblings like zemax_add_configuration_operand, zemax_delete_configuration_operand, or zemax_mce_add_operand.

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 versus adding/deleting an operand, or versus zemax_get_configuration_operands for reading. Usage is only implied by the verb 'Set'. No prerequisites (e.g., the configuration and operand row must already exist) are mentioned.

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