set_instance_overrides

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

With no annotations, the description carries the full burden of behavioral disclosure. It explicitly reveals the main mutating effect: target instances will be swapped to the source component and all copied override properties will be applied. It does not discuss reversibility, errors, or permissions, but the core behavioral transformation is clearly stated, which is strong for a tool with no annotation support.

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 two concise sentences with no filler. The main action is front-loaded in the first sentence, and the second sentence adds the essential behavioral detail. Every word contributes to the agent's understanding.

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 tool with two required parameters, no annotations, and no output schema, the description covers the action, the target selection context, and the resulting transformation. It could mention prerequisites more explicitly or describe failure behavior, but the essential information needed to invoke the tool correctly is present.

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 the schema already documents both parameters. The tool description adds minimal parameter-level meaning beyond restating that target instances are involved; it does not clarify the relationship between sourceInstanceId and targetNodeIds beyond what the schema already provides. Thus the baseline score of 3 is appropriate.

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 opens with a specific verb and resource ('Apply previously copied overrides to selected component instances') and then states the concrete outcome: target instances are swapped to the source component and all copied overrides are applied. This clearly distinguishes it from the sibling get_instance_overrides, which reads rather than applies.

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 phrase 'previously copied overrides' and 'selected component instances' conveys the intended workflow context, making it clear the tool is used after copying overrides and on a current selection. It does not explicitly state when not to use it or name alternatives like get_instance_overrides, but the context is sufficient for an agent to infer the correct situation.

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