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

No annotations are provided, so the description carries the disclosure burden. It helpfully enumerates the return fields (slug, name, tagline, category, website, detail URL), but says nothing about auth requirements, result ordering, or pagination behavior even though a limit parameter exists.

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?

Two tight sentences with no filler, and the purpose is front-loaded before the return-value list. Nothing is wasted, though the second sentence is a somewhat mechanical field enumeration.

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, the description correctly compensates by listing returned fields, and the schema covers all parameters. Remaining gaps (pagination, result ordering, query matching defaults) are minor for a simple search 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 the schema already documents query, limit and category fully, including the category slug list. The description's mention of category in the return fields adds only marginal context beyond the schema, 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 specific verb (Search) and resource (VaneTools plugin directory, editor and agent plugins), which is distinguishable from siblings like search_mcp_servers, search_tools and search_skills by the 'plugin' resource. It does not, however, explicitly contrast itself with those sibling search tools.

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?

No when-to-use guidance, no alternatives named, and no exclusions. With seven sibling search/get tools available, the description offers nothing to help the agent choose search_plugins over search_tools or search_mcp_servers.

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