list_procedural_textures

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds only the scope of what is enumerated; it says nothing about catalog size, pagination, or whether the list is static or reflects user-saved content, which are the remaining behavioral questions for a discovery 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 sentence with the verb front-loaded and zero filler. Every element (types, palettes, presets) carries information about the return scope, and nothing is repeated from the title or annotations.

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 parameters and no output schema, the description carries the burden of describing what the caller receives, and it only names three categories without indicating structure, grouping, or size. For a zero-arg discovery tool this is adequate but leaves the agent guessing about the shape of the result before calling it.

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, so there is no parameter semantics for the description to explain and the baseline of 4 applies. Nothing is undocumented or misleading on this axis.

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?

Specific verb ('List') plus resource ('procedural texture types, palettes, and presets') that enumerates exactly what comes back, so the agent knows the scope without opening a schema. It does not name or distinguish itself from nearby siblings such as list_custom_palettes, list_decorations, or apply_procedural_texture, so it falls short of 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?

The listing framing implies this is a discovery step that precedes apply_procedural_texture, but no when-to-use statement or alternative is given. An agent cannot tell from the description whether this overlaps with list_custom_palettes or list_decoration_presets, which is a real ambiguity in this crowded sibling set.

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