setup_vellum_sim

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

No annotations are provided, so the description carries full burden. It discloses only that it sets up a Vellum simulation, with no details about node creation, side effects, required context, or return behavior. This is insufficient for a setup 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 a single sentence, which is concise and front-loaded. However, it sacrifices essential information; despite being short, it doesn't fully exploit the space to add value beyond the tool name.

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 4 parameters and no output schema, the description is severely incomplete. It does not describe the setup process, parameter semantics, or expected outcomes, making it hard for an agent to select and invoke correctly.

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 0%, and the description does not elaborate on any parameters. The schema defines name, sim_type, parent_path, and source_path, but the description adds no meaning to these, leaving the agent to infer parameter purposes from names alone.

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 tool's function: setting up a Vellum simulation for cloth, hair, or grain. It uses a specific verb ('set up') and resource ('Vellum simulation'), and distinguishes it from sibling simulation setup tools like setup_pyro_sim, setup_rbd_sim, and setup_flip_sim.

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 implies use for Vellum simulations but does not explicitly state when to use this tool over alternatives or provide exclusions. There is no mention of prerequisites, conditions, or alternative tools, so usage context is only inferred.

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