get_theme_presets

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

The description discloses the behavioral change (no default, presets must be chosen) and the version context, which is useful. However, with no annotations provided, the description carries the full burden and could clarify what exactly is returned (e.g., a list of preset identifiers or objects), but it stops short.

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 two sentences, front-loaded with the main purpose ('Available DS theme presets'), and the second sentence adds valuable context without redundancy. No wasted words.

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 tool with no output schema, the description adequately conveys that it returns available theme presets and explains the broader context of brand-neutralization. It could be more explicit about the output format, but given the simplicity, it is reasonably complete.

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 has zero parameters, and the schema coverage is 100% (vacuously). According to baseline guidance, 0 params earns a 4. The description adds no parameter details, but none are needed.

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 'Available DS theme presets' clearly indicates the tool returns a list of theme presets, and the 'get' prefix reinforces the retrieval action. It is not a tautology and distinguishes from siblings like get_design_tokens by focusing on theme presets specifically.

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 description provides context that after v0.34, there is no baked brand default, so users must pick a preset or apply their own ramps. This implies when to use the tool (to discover available presets) and gives an alternative (custom ramps), though it does not name specific sibling tools.

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