render_variants

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

No annotations are provided, so the description carries the full behavioral burden. It discloses that outputs are look-dev renders plus a sheet and are not game views, but says nothing about file writes, output location, side effects, or whether rendering is expensive or requires a prior bake.

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 front-loaded sentence with no filler, which is efficient. Its terseness, though, leaves key concepts and parameters under-specified rather than making every word earn interpretive value.

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 only partial schema coverage across three parameters, the definition is too thin for a tool that likely produces files. An agent lacks the input/output and side-effect information needed to invoke it reliably.

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 only 33%, so the description should compensate, but it explains neither the required 'bake_folder' nor the 'variants' parameter. The schema's 'views' description ('right, left, close') is not elaborated on, leaving required-parameter meaning and accepted variant values unclear.

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 names a specific action ('renders') and object ('the variants'), and adds that it produces 'a sheet of them' in a look-dev context. However, 'variants' is never defined, and the tool is not differentiated from related siblings like bake or read_finish, so an agent cannot confidently tell when this render step applies.

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 versus bake, read_finish, or other sibling tools, nor any prerequisites or exclusions. The only usage clue is the parenthetical 'not a game's view', which hints at intent but does not route the agent among alternatives.

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