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

Annotations already cover the safety profile (readOnlyHint, destructiveHint=false, openWorldHint), so the bar is lower. The description adds useful non-annotation behavior: results are ranked and trimmed, include id/title/summary/docs_url, and the 'detail' setting controls verbosity and bounds — that return-shape disclosure is valuable given there is no output schema.

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?

Front-loaded verb+resource followed by scope and the retrieval follow-up. The long enumeration of covered areas is verbose but earns its place by helping keyword matching; there is little true filler.

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?

No output schema exists, and the description compensates by describing the returned fields and the two-step search→elementor_get flow, plus the concise/detailed behavior. Adequate for an optional-parameter search tool, though pagination/ranking specifics are not detailed.

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, category, detail, and limit (including the detailed=12 widening). The description body adds no parameter syntax or format meaning beyond that, 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 a clearly bounded resource (the Elementor + WordPress development knowledge base), then enumerates the covered domains (widgets, controls, dynamic tags, hooks, best practices, etc.). This distinguishes it from sibling tool elementor_get (full guide) and elementor_categories (browsing 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?

Explicitly states when to use it ('whenever building an Elementor widget/control/dynamic tag/form/theme location OR a WordPress plugin feature') and names the follow-up alternative, elementor_get(id), for full detail. It does not, however, say when not to use it or compare against other search-like siblings.

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