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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, so the safety profile is fully covered by structured data. The description adds nothing beyond that — no mention of pagination behavior, default page size, or result ordering — so it contributes no behavioral context of its own.

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?

A single front-loaded sentence with zero verbosity and no redundancy. It is efficient, though the brevity edges toward under-specification rather than disciplined conciseness.

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?

Against a 5-parameter, fully-documented schema and complete read-only annotations, the definition is minimally sufficient but leaves gaps: no return-shape or pagination note that would help an agent page through comments, and no routing to the moderation/reply siblings. Adequate, not complete.

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?

Schema description coverage is 100%, so all five parameters (page, post, status, site_id, per_page) are already documented in the schema with defaults and bounds. The description's 'optional filters' adds no syntax, format, or constraint detail beyond that, so the baseline of 3 applies.

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?

States a specific verb+resource ('List WordPress comments'), which is clearly distinct from mutation tools like wp_moderate_comment or wp_reply_comment. However, it offers no explicit differentiation from sibling read tools (wp_list_posts, wp_search_content), and 'with optional filters' is generic filler rather than naming the filterable dimensions.

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?

No when-to-use guidance and no alternatives named. The phrase 'with optional filters' implies filtering is possible but never says which filters matter or when to prefer this over wp_search_content or wp_moderate_comment.

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