Nsc Add Object

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

No annotations are provided, so the description carries the full behavioral burden and fails to disclose mutation semantics: nothing about whether the object is added at the end, what happens on failure, or any permissions required. For a mutating tool with zero annotation coverage this is a significant gap.

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 short sentence with no wasted words. It is concise, though the brevity comes at the cost of useful detail rather than by editing away redundancy.

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 mutation tool with no annotations, no output schema, and optional parameters, the description should explain state changes, return behavior, and how it differs from insert/set siblings. It omits all of this.

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 both parameters (comment, objectType) are already documented in the schema. The description adds no syntax, format, or default information beyond the schema, so 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?

The description states a verb and resource ('Append a non-sequential object'), which is clearer than a bare name restatement but adds almost nothing beyond the title 'Nsc Add Object'. It does not distinguish itself from close siblings like zemax_nsc_insert_object or zemax_nsc_set_object.

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?

There is no guidance on when to use this tool versus zemax_nsc_insert_object, zemax_nsc_set_object, or zemax_nsc_remove_object. The agent must infer from the one-word difference between 'append' and 'insert'.

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