wp_get_meta_catalog

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

No annotations are provided, so the description carries the burden of behavioral disclosure. 'Get' signals read-only intent and 'unified across adapters' signals aggregation, but the return structure, adapter discovery behavior, and error semantics are not described. Acceptable but minimal for a zero-parameter read-only tool.

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 a single front-loaded sentence with no filler. Every word adds meaningful scope or purpose.

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 no-parameter read-only catalog tool, the description is nearly complete: an agent knows exactly what action to invoke and what resource to expect. The main gap is that the exact contents of the catalog are unspecified and there is no output schema to fill that void, but this is a minor issue given the tool's simplicity.

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 input schema has zero properties and 100% schema description coverage, so the baseline is 4. There are no parameters to document, and the description does not need to compensate for any missing parameter meaning.

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 names a specific verb ('Get'), a specific resource ('unified meta field catalog'), and scopes it across ACF, AIOSEO, and other registered adapters. This clearly distinguishes it from narrower siblings like wp_get_acf_fields or wp_get_page_seo.

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 implies when to use the tool: when a cross-adapter meta field catalog is needed. However, it never explicitly states when not to use it or names alternatives, leaving the routing decision to inference.

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