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

No annotations provided, so description carries full burden. It describes what is retrieved but does not disclose potential behavioral traits such as pagination, rate limits, or required permissions. Since output schema exists, response structure is documented, but behavioral aspects beyond that are lacking.

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?

Two sentences, front-loaded with main action, no wasted words. Perfectly concise while still providing examples and usage guidance.

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?

Given 6 parameters all documented in schema and an output schema available, the description covers purpose and usage adequately. Missing some context about default behaviors (e.g., startTime defaults) but those are in schema. Overall complete for a tool with rich structured metadata.

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 coverage is 100%, so baseline 3 applies. Description does not add extra meaning to individual parameters beyond what schema already provides. It offers general context but no additional semantic guidance.

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?

Description clearly states the tool retrieves audit logs of Chrome browser activity with specific examples like login events, policy violations, extension installs. Differentiates from sibling tools like DLP rule management or authentication by specifying use for security investigations and DLP tuning.

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?

Explicitly says 'Use this for security investigations, auditing user actions, and to help tune DLP rules,' providing clear context. Does not mention when not to use or list alternative tools, but the context is sufficient for most cases.

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