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 the authorization constraint (owners only), which is genuinely beyond the structured data, but leaves the scope of 'recent', ordering, and truncation behavior undisclosed.

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 purpose and then the access constraint. No filler and nothing redundant.

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 one-parameter read tool with no output schema, the definition covers purpose and permission adequately. It is still thin on the two things an agent needs to call it well: what 'recent' means and how 'limit' behaves.

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 single parameter 'limit' has 0% schema description coverage and no mention in the description, so nothing in the definition explains its default, its max of 200, or whether omitting it returns a default page. No meaning is added beyond the bare schema.

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?

States a specific verb and resource ('Show recent alert events') and parenthetically enumerates the event kinds (crashes, kills, rate limits, failed deploys), which distinguishes the content from list_alert_rules. It stops short of naming the sibling alert-rule tools, so an agent must infer the boundary.

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?

Adds a real usage precondition, 'Workspace owners only', which tell an agent whether to attempt the call at all. However, it never states when to use this versus list_alert_rules or get_audit_log, and does not define what 'recent' means (time window, default limit).

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