wp_get_post_statuses

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

With no annotations, the description carries full burden. It transparently implies a read-only list operation and discloses that it includes both built-in and custom statuses. It doesn't detail return format or edge cases, but for a zero-parameter list tool, this is adequate.

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, concise sentence that front-loads the core action. It includes useful illustrative examples (publish/draft/pending/private/future) without verbosity. Every word earns its place.

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 tool with no parameters, no output schema, and a simple list operation, the description is complete. It fully explains what the tool returns (all statuses, including custom ones) and requires no further context.

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 0 parameters, so the baseline is 4. The description adds nothing about parameters because there are none to explain. This is appropriate.

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 states the tool's function: 'List all available post statuses.' It specifies the resource (post statuses) and the action (list), and distinguishes itself from sibling tools like wp_get_post_types and wp_get_taxonomies by focusing specifically on statuses. The inclusion of built-in and custom statuses adds depth.

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 makes it obvious when to use this tool: whenever you need a complete list of post statuses. While it doesn't explicitly mention alternatives, the context is clear and no exclusions are needed. For a simple listing tool, this is sufficient guidance.

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