Check WordPress Environment

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

With no annotations, the description carries the full burden of behavioral disclosure. It reveals that the tool returns the site URL and environment label, and its 'SAFETY CHECK' framing implies a read-only, non-destructive operation. While it doesn't explicitly state 'read-only,' the context is sufficient and adds value beyond the raw name.

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 exceptionally concise, using a warning symbol, a clear imperative, and a terse explanation of return values. Every sentence earns its place, and the critical safety instruction is front-loaded.

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 the tool's simplicity (no parameters) and the absence of an output schema, the description is complete. It explains the purpose, usage, and return values (site URL and environment label), covering all essential context an agent needs to invoke the tool 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, so the description need not explain parameter semantics. The schema already provides full coverage (vacuously), and the description does not introduce any confusing parameter-related information, earning the baseline score for no-parameter tools.

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 uses a specific verb+resource ('Check WordPress Environment') and clearly states it returns the site URL and environment label. It distinguishes itself from sibling write/update/delete tools by being a safety check, making its purpose unambiguous.

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 explicitly instructs to call this tool before any write, update, or delete operation, and strongly emphasizes 'Never skip this on write operations.' This provides clear, actionable guidance on when to use the tool, even without naming alternatives.

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