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

Annotations already declare readOnly, idempotent and non-destructive, so the safety profile is covered. The description adds the authorization constraint (admin/moderator only), which annotations cannot express, and clarifies the queue semantics. Minor gaps: no pagination or ordering behavior for the queue.

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?

Four short sentences, each carrying a distinct fact: what the queue is, who can call it, what it returns, and which sibling handles deletion. The first fragment slightly duplicates the second sentence but costs little.

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 single-parameter read tool with full schema coverage and annotations, the description supplies everything needed to select and call it: scope, permission, and the follow-up action. Only queue ordering/pagination is unaddressed, which is minor here.

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% and the single 'group' parameter is fully documented with an example in the schema. The description adds no format or scoping detail beyond that, so baseline 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 and resource ('Lists the posts in the group's Reported queue that members flagged against the rules'), which clearly separates it from list_posts and get_post. The opening fragment ('Posts members reported to the admins') is slightly loose but the second sentence nails the scope.

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?

Names the access condition (admins and moderators only) and routes the removal case to delete_post, which is genuine when-to-use guidance. It does not explicitly contrast with list_posts, so an agent must infer that non-reported posts come from elsewhere.

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