list_themes

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

With no annotations, the description carries the burden of behavioral disclosure. 'List' reasonably implies a read-only, non-destructive operation, and 'identifiers' clarifies the granularity of results. However, it does not disclose ordering, failure behavior, or whether the operation accesses persistent storage or memory, which would add useful transparency.

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 concise sentence that front-loads the core action and resource. Every word contributes meaning, with no filler or redundant detail.

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, the description is nearly complete: it states the action, result granularity, and workspace scope. The absence of an output schema means the description could optionally specify the return format, but 'list theme identifiers' adequately conveys that the result is a collection of identifiers.

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 an empty schema, so there is nothing to document. Baseline 4 applies because no parameter explanation is needed and the description is not missing any parameter semantics.

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 states a specific verb ('List'), a precise resource ('theme identifiers'), and a scope ('current workspace'). This clearly differentiates it from the sibling tool 'list_tags', which targets tags rather than themes.

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 implies when to use the tool (when you need all theme identifiers), but it provides no explicit guidance about when not to use it or when a sibling tool like 'tag_theme', 'trace_theme', or 'search' would be more appropriate. No alternatives or exclusions are mentioned.

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