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 safety profile is clear. The description adds the 'recent' time scoping, but it does not disclose pagination behavior, ordering, default time windows, or result count limits.

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 verb and resource, then lists the optional filters. There is no filler or redundant restatement of the tool name.

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 should explain what a successful response contains or at least mention pagination/limits; it does neither. Time filter units are also unexplained. The description is adequate for a basic call with workspaceSlug, but incomplete for full tool understanding.

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 very low at 20%, and the description only names 'actor, action, and time filters' without explaining formats or semantics. In particular, fromAt and toAt are numbers with no stated unit or timestamp convention, so the description does not compensate for the schema's gaps.

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') and a concrete resource ('workspace audit events'), and names the optional filters (actor, action, time). This clearly distinguishes it from sibling list_* tools like list_assets or list_reports, even without reading the schema.

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 intended use is implied: an agent can infer to call this tool when it needs recent workspace audit events. However, it provides no explicit when-not-to-use guidance, no mention of alternatives, and no discussion of prerequisites beyond the required workspaceSlug.

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