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

With no annotations, the description carries the full burden. It discloses that the tool is browser-based and generates copy-pasteable HTML for WordPress, adding useful behavioral context beyond the simple action. It does not mention any limitations or side effects, but for a 0-parameter client-side tool, it is reasonably transparent.

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 plus a parenthetical, every word earns its place. It front-loads the core function and adds useful usage context without wasting space.

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 low complexity (no params, no output schema), the description is sufficient to understand its purpose and output. It mentions the output format (HTML), target platform (WordPress), and speed, which covers the essential context an agent needs.

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 no parameters, so the schema is trivially complete. The description correctly implies no inputs are required, which aligns with the empty schema. The baseline for 0 params is 4, and nothing in the description contradicts this.

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 it generates product comparison table HTML, which is a specific verb and resource. It implies a distinct purpose, though it does not explicitly contrast with sibling tools that also generate HTML or templates.

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 usage by mentioning it can be pasted into WordPress and generates output in 30 seconds. However, it does not provide explicit when-to-use vs alternatives or exclusions, leaving the user to infer the best scenario.

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