set_material

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not state whether attaching material overwrites a prior material, whether the solid must already exist, what permissions are needed, or what the operation returns 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?

A single efficient sentence with the verb front-loaded. It is well sized, though its brevity is partly under-specification rather than compression of real information.

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?

With no annotations, no output schema, and two undocumented parameters at 0% coverage, the definition is too thin for a mutation tool. An agent cannot confirm target format, overwrite behavior, or return value from the available 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?

Schema description coverage is 0% for two required parameters, so the schema gives no meaning for solid_id or material_name. The description does not clarify the identifier format for solid_id or whether material_name must match an existing library entry, leaving both parameters underspecified.

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?

States a specific verb (attach) and resource (material metadata to a solid), which is clear on its own. However, it offers no differentiation from siblings like set_entity_property or define_attribute, so the agent must infer context, keeping it below a 5.

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 such as set_entity_property or the various set_* tools in the sibling list. No prerequisites, no exclusions, and no context for the standard workflow are given.

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