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

No annotations supplied, so the description carries full behavioral burden. It states it returns install commands but not the result shape, ranking, whether it's read-only, pagination, or match behavior (substring vs fuzzy). Significant gaps.

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 compact sentences, front-loading purpose then return value. No wasted words, though the return clause is the only behavioral content.

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 search tool with 0 required params and no output schema this is roughly adequate, but limit semantics, default behavior, and result format are left unspecified and there are no annotations to compensate.

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 coverage is 67%; query and category already documented in schema. limit is undocumented in both schema and description (no semantics on default or purpose), and the description doesn't clarify whether query and category combine or are alternatives.

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?

Clear verb (Search) + resource (seoskills.sh catalog of SEO agent skills) + scope (by keyword and/or category). Distinguishes itself from siblings get_skill (fetch one) and list_categories (enumerate categories).

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?

Implies discovery/searching use but gives no explicit when-to-use or when-not, and does not point to the siblings get_skill or list_categories for alternative flows. Minimal guidance.

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