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

With no annotations provided, the description fully discloses behavior: it makes exactly one minimal audit-log request, reports pass/fail with a plain explanation plus remediation steps, and never echoes secret material (the access key shows only the last 4 characters). This goes well beyond a bare operation statement and gives the agent confidence about side effects and output safety.

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 purpose is front-loaded in the first sentence, and the remaining sentences carry useful information about behavior, triggering, and secret handling. The 'Returns' section slightly overlaps with the provided output schema, but it only lists the key dictionary fields and is not padded. Overall it is tightly written for the information it needs to convey.

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 no parameters and a full output schema, the description covers everything an agent needs: what is checked, when to run it, what side effects occur (one request, no secret disclosure), and what the result looks like. There are no missing pieces that would cause an agent to misuses the tool.

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 zero parameters, so the baseline is 4. The description does not need to explain parameter meaning, and the empty input schema leaves nothing ambiguous; the description instead focuses on the output, which is appropriate here.

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 opens with a specific verb and resource: 'Verify the configured API keys can actually read the audit log,' which clearly states what the tool does. It also distinguishes itself from the sibling data-retrieval tools (list_activity_events, summarize_activity, etc.) by positioning this as a diagnostic preflight check rather than an analytics operation.

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 gives an explicit trigger condition: 'Run this first when another tool returns an authentication or permission error.' This is clear contextual guidance, but it does not mention when not to use it or name alternative tools—though no sibling performs the same diagnostic role, so exclusions are not necessary.

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