create_profile_variant

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 discloses key behaviors: merging overrides, writing to a specific file path, and tracking in profile_hierarchy.json. However, it does not mention whether validation occurs, permissions needed, or potential side effects beyond file creation. A bit more detail would be ideal, but the current disclosure is strong.

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 a compact paragraph with clear front-loading of purpose, followed by process and parameters. It could be slightly more concise by removing the 'Params:' listing that partially repeats the schema, but it remains efficient overall.

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?

Given the tool has 4 parameters, no annotations, and an output schema (not shown), the description covers the merging logic, file output, and hierarchy tracking. It does not describe the return value explicitly, but the output schema likely handles that. The description feels sufficiently complete for a creation tool with moderate complexity.

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 input schema has zero parameter descriptions (0% coverage), so the description compensates by listing parameters and providing an example for 'overrides'. However, it does not fully describe constraints for 'parent_profile' (name vs path), 'variant_name' (allowed characters), or 'description' format. The example helps, but ambiguity remains.

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 starts with 'Create a child PP3 profile variant derived from a parent template,' which clearly states the action and resource. The details about merging overrides and tracking relationships further clarify what the tool does, distinguishing it from siblings like 'generate_pp3_profile' or 'apply_template'.

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 explains the process but lacks explicit guidance on when to use this tool versus alternatives. Users must infer from context when to choose this over similar siblings like 'update_base_profile' or 'generate_pp3_profile'. No when-not-to-use or alternative references are given.

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