add_activate_variant_set_node

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

No annotations are provided, so the description must disclose side effects, prerequisites, and mutation behavior. It only states that it adds a node and activates variants, without mentioning required existing assets (blueprint, variant set), whether compilation is triggered, or potential errors. This is a significant gap 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.

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

The description is well-structured with a title, main purpose, args list, KB reference, and example. It is front-loaded with the core action. There is some redundancy ('From Ch. 20: Activates all variants within a Variant Set' repeats the purpose), but overall it is concise and organized.

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 blueprint node-add operation, the description covers the essential parameters and provides an example. However, it omits prerequisites (e.g., blueprint must exist, variant set must be valid), expected output or return value, and failure modes. The KB reference helps but is not sufficient for full autonomous execution.

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?

The description includes an 'Args' section that explains each parameter: blueprint_name, lvs_variable, variant_set_name, and node_position. This adds meaning beyond the schema, which has no descriptions (0% coverage). The example also demonstrates usage, so parameters are well contextualized.

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 verb (add) and resource (ActivateVariantSet node), and explains the effect: 'activate all variants in a set.' It distinguishes itself from the singular sibling add_activate_variant_node by emphasizing 'all variants,' but does not explicitly name alternatives. The purpose is clear and specific.

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 gives a use case ('Useful for resetting or applying a full configuration') but does not specify when to avoid this tool or mention alternatives like add_activate_variant_node for single-variant activation. Usage context is implicit rather than explicit.

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