set_object_filament

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

With no annotations, the description carries the full burden and falls short: it does not say whether assignments overwrite prior ones, whether the filament slot must be loaded/exist, or whether the object must be selected or already on a plate. Only the part-level capability is disclosed beyond the schema.

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 front-loaded sentence with no filler, and the primary object-level behavior leads before the part-level nuance. Brevity is a virtue here, though it borders on under-specification.

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?

A mutation tool with zero annotation coverage, no output schema, and three undocumented parameters warrants more: valid filament indices, part-name resolution, and side effects on existing assignments are all absent.

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 coverage is 0%, so the description must compensate. It usefully clarifies that 'filament' is a slot identifier and 'part' is a part name, but gives no valid range, index base, or format for either, leaving real gaps.

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 ('Assign') and resource ('a filament slot'), plus the two scopes it can target: whole object or a named part. This distinguishes it reasonably from the plate/global 'set_filament' sibling by scope, though it never names that sibling explicitly.

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 'or to one of its parts' phrasing implies when to use the optional part parameter, but there is no explicit guidance on when to choose this over set_filament, use_ams_filaments, or set_object_setting, and no prerequisites are stated.

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