list_template_themes

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

readOnlyHint=true already declares this is a safe read, so the description's remaining value is the return payload (id, name, preview_url, thumbnail, categories) and the data source domain. It says nothing about pagination behavior or result limits, so this is adequate but not rich.

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?

Three short sentences, purpose front-loaded, then usage, then return shape. Every sentence carries information and none repeats structured data.

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 output schema, listing the returned fields is genuinely useful and covers the main gap. It leaves pagination semantics (how page/limit interact, total counts) unaddressed, which is a minor omission for a simple list tool.

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 100%, so q, lang, page, and limit are all documented in the schema itself. The description adds no syntax, format, or default guidance beyond the schema, so the baseline of 3 applies.

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?

States a specific verb+resource: search/list the public Webcake template marketplace, and scopes it to keyword matching. This implicitly separates it from semantic_search_themes and list_themes, though it never names them explicitly.

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?

Gives a clear context of use ('match customer brief against existing templates by keyword'), which tells the agent when to reach for this tool. It stops short of naming alternatives (e.g. semantic_search_themes for concept-based lookup) or stating exclusions.

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