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

No annotations are provided, so the description carries the full burden of explaining behavior. It states that a report is submitted for admin review, but does not disclose side effects, whether the action is a write, whether it is idempotent, what happens after reporting, or any permission requirements. For an action-oriented tool, this is a significant gap.

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 sentence with no filler and gets to the point quickly. It could be improved with clearer wording around 'accessible message', but structurally it is concise and 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?

For a tool with three parameters, no annotations, and no output schema, the description is too minimal. It does not explain the relationship between reason, agentId, and messageId, what the report records, what the response is, or any constraints on calling the tool. An agent would have to guess at important invocation details.

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 0%, so the description must compensate. It roughly maps 'accessible message' to messageId and 'visible agent' to agentId, which adds some meaning. However, it does not explain the required 'reason' parameter, possible constraints, or whether agentId/messageId are mutually exclusive, optional, or both allowed.

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 states a clear verb and resource: report a message or agent for administrator review. It is distinguishable from sibling tools because none of them cover reporting/admin review. The phrase 'accessible message' is slightly ambiguous, but the overall intent is clear.

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 when to use the tool: when a message or agent should be flagged for administrator review. However, it does not explicitly state when not to use it or mention any alternative tools, so the guidance is only implicit rather than explicit.

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