wp_seo_detect_provider

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

With no annotations, the description carries the behavioral transparency burden. It explains what the tool reports (provider and capabilities) and connects that to downstream persistence/rendering behavior. However, it does not explicitly state side effects or permissions, though the name 'detect' implies a read-only operation.

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?

The description is concise—two sentences—with the core purpose front-loaded and the usage guideline following immediately. Every word earns its place; there is no redundant detail or 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?

Given its simplicity (0 params, no output schema), the description is complete. It states what the tool does, what it reports, and why to use it before wp_seo_set_meta. No critical information is missing for an agent to select and invoke it correctly.

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?

The tool has zero parameters, and the input schema is empty. Baseline for 0 params is 4. The description adds context about possible return values (provider list and capabilities), which is helpful even though it does not pertain to parameter semantics.

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?

The description clearly identifies the tool's function with the verb 'detect' and specifies the resource: the active SEO provider (bridge/yoast/rankmath/null). It also distinguishes itself from siblings by noting that it reports capabilities relevant to wp_seo_set_meta, making its purpose unmistakable.

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?

The description provides an explicit usage directive: 'Use this before calling wp_seo_set_meta to know what fields will actually be persisted and rendered.' This tells the agent exactly when to invoke this tool and why, differentiating it from alternatives.

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