apply_modifier

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

The description does not disclose the destructive nature of applying a modifier (it permanently alters the mesh). No annotations are present to compensate. The lack of any behavioral detail leaves the agent unaware of the irreversible side effects.

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 extremely brief and front-loaded, which is efficient. However, the brevity sacrifices essential detail, making it borderline too terse. Still, it is not verbose, so it earns a decent score for conciseness.

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 large number of sibling modifier tools, this description lacks almost all necessary context: it does not clarify the precise operation, prerequisites (e.g., a modifier must already exist), or consequences. A user or agent cannot confidently choose this tool based solely on the provided information.

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?

Both parameters (object and modifier) are only typed as strings with no description. The schema provides no additional information (0% coverage). The description does not explain how to specify the object (by name? reference?) or what identifier is expected for the modifier. This is a significant gap.

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 clear action ('apply modifier to mesh'), but it does not specify what 'apply' means in Blender (i.e., permanently baking the modifier's effect), nor does it differentiate from sibling tools like add_modifier, set_modifier, or remove_modifier. The action is understandable but ambiguous without domain knowledge.

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 alternatives. For example, it does not mention that it should be used only when a modifier is meant to be permanently applied, or that set_modifier might be more appropriate for adjusting settings. No usage context is provided.

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