wp_detect_page_builder

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

Discloses a key dependency (companion plugin) and the reason the check matters, but does not specify output format, failure behavior if plugin missing, or confirm read-only nature. With no annotations, more could be said.

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 focused sentences: purpose first, then consequence and prerequisite. No 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?

For a simple zero-parameter detector, description covers what, why, and prerequisite. Omits explicit output shape but domain context implies a simple boolean/list; acceptable for low complexity.

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?

Tool has zero parameters, so schema already fully covers inputs; baseline 4 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?

Clearly states it detects specific page builders (Elementor, Divi, Beaver Builder, WPBakery) and why this matters (content outside post_content), distinguishing it from general detection tools like wp_seo_detect_provider.

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?

Explains the use case: detecting page builders that limit MCP editing, and notes a prerequisite (companion plugin). It does not explicitly name alternatives or state when not to use, but context is clear.

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