set_instance_overrides

Copy overrides from a source instance and apply them to selected target instances, swapping to the source component with all properties.

Instructions

Apply previously copied overrides to selected component instances. Target instances will be swapped to the source component and all copied override properties will be applied.

Input Schema

NameRequiredDescriptionDefault
targetNodeIdsYesArray of target instance IDs. Currently selected instances will be used.
sourceInstanceIdYesID of the source component instance
Behavior2/5

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

No annotations provided, so description carries full burden. Discloses the effect (swap and apply) but omits details on reversibility, permissions, or error conditions. Limited transparency for a mutation tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

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

Two concise sentences with no fluff. Information is front-loaded and every sentence adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Adequate for a 2-param mutation tool with no output schema. Missing details on the source of overrides and return behavior, but sufficient for basic usage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, baseline 3. Description adds meaning by explaining the effect of each parameter: targetNodeIds become swapped, sourceInstanceId defines the source. This goes beyond schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states the action 'Apply previously copied overrides' and the resource 'selected component instances', with specific effect of swapping to source component. Distinguishes from sibling tools like get_instance_overrides.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Implies prerequisite of previously copied overrides but does not explicitly state when to use versus alternatives like set_component_property. No exclusions or when-not-to-use guidance.

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