list_procedural_textures

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

No annotations are provided, so the description carries the full burden. It does disclose a behavioral trait — 'all available' implies an unfiltered, complete catalog with no arguments and no pagination — but it says nothing about permissions, rate limits, or result size/caching.

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 tight sentence with the verb and the full result enumeration front-loaded. Nothing is padded, though it is minimal enough that it borders on under-specification rather than model 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?

For a zero-parameter, no-annotation read tool with no output schema, the description usefully enumerates the three categories returned, effectively standing in for a return-value summary. It does not distinguish built-in palettes from the custom palettes exposed by list_custom_palettes, leaving a small ambiguity for the agent.

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?

The tool takes zero parameters, and the schema is empty, so there is nothing to document beyond the baseline. The description correctly spends no words on parameter syntax.

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 gives a specific verb (List) plus the resources returned (procedural texture types, palettes, presets), so the agent knows exactly what comes back. It stops short of naming the counterpart tool apply_procedural_texture, so sibling differentiation is implicit rather than stated.

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 when-to-use guidance, no mention of apply_procedural_texture as the follow-up action, and no statement about when this list is relevant. The agent can infer it is a discovery step before applying a texture, but nothing in the text says so.

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