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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the agent knows it is a safe read operation. The description adds context about scoping (owner wallet) and redaction, but does not explain what 'recent' means, whether there is pagination, or what fields are redacted. This is useful but not rich.

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, efficient sentence that front-loads the core purpose. Every word adds context: 'List', 'recent', 'redacted', 'MCP audit events', 'authenticated owner wallet'. No filler or redundancy.

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?

With no output schema, the description does not describe the return format or clarify vague terms like 'recent' or 'redacted'. However, the tool is relatively simple, annotations cover the safety profile, and the basic purpose is clear. Adequate but with gaps in filtering semantics and response structure.

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%, and the description does not mention any of the four parameters (limit, since, method, resultStatus). The names are somewhat self-explanatory, but the description adds no meaning beyond the schema, failing to compensate for the lack of property descriptions.

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 ('List'), identifies the resource ('MCP audit events'), and adds scope ('recent', 'redacted', 'authenticated owner wallet'). This clearly differentiates it from siblings like mcp.audit.summary (which likely summarizes) and mcp.access.list (which lists access events).

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 guidance is provided about when to use this tool versus alternatives such as mcp.audit.summary or mcp.access.list. The description implies usage for retrieving audit events but does not state any conditions, prerequisites, or exclusions.

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