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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds a genuine behavioral fact beyond them — the owner-only authorization requirement — but leaves the main unknown for a zero-parameter read tool unexplained: how far back 'recent' reaches and roughly how much data comes back.

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 short sentences with zero filler; the resource and its content are front-loaded and the access restriction follows immediately. Nothing is repeated from the title or annotations.

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 zero-parameter, read-only tool with full annotation coverage and no output schema, this is close to sufficient: resource, content shape, and access requirement are all stated. The only shortfall is the undefined recency window, which an agent would need to set expectations about result volume.

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?

With zero parameters the schema baseline is 4, and the description is consistent with that by implying the tool is a fixed, unfiltered view. The only marginal loss is that 'recent' is undefined, so the agent cannot know whether any implicit scoping applies.

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?

Names a specific verb and resource ('Show the workspace's recent audit log') and expands it with 'who did what, when', which tells the agent what fields the log carries. It is distinguishable from siblings like get_connection_activity or list_alert_events by resource, though no sibling is named explicitly.

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?

States the permission gate ('Workspace owners only'), which implicitly tells a non-owner agent not to call it. However, there is no guidance on when to prefer this over adjacent activity tools such as get_connection_activity, and no mention of what 'recent' covers or whether any alternative exists for older history.

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