search_themes

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds no behavioral context beyond that: it says nothing about pagination behavior, the default layout filter, or what the catalog results contain.

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 front-loaded sentence with zero waste. It is efficient, though arguably under-specified rather than maximally concise — nothing is padded, but nothing extra is offered either.

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 simple, all-optional, read-only catalog search with a fully documented schema and no output schema, the description is adequate but thin. It omits how results are paged or filtered, which an agent browsing a catalog would benefit from knowing.

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 limit, offset, and theme_layout_types are already documented in the schema, including their defaults. The description adds no extra meaning about filtering or paging, so the baseline 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 clear verb ('Browse') and resource ('catalog of available wedding-website themes'), which is enough to distinguish it from get_current_theme or update_current_theme. However, it does not explicitly name a sibling or clarify how it differs from browsing related catalogs like search_card_catalog.

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?

Usage is implied — you browse themes presumably to pick one — but there is no explicit statement of when to use this versus get_current_theme (inspect the active theme) or update_current_theme (apply a theme). No prerequisites or exclusions are given.

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