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

Annotations already indicate readOnlyHint=false, idempotentHint=true, and destructiveHint=false. The description adds valuable context by explaining the state change ('marks it as seen/being-handled') and emphasizing it does not resolve the alert. The write scope requirement is also disclosed, which aligns with readOnlyHint=false. No contradictions with annotations.

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 exceptionally concise: two sentences that front-load the core purpose, then add key constraints (not resolving, optional note, scope requirement). Every sentence contributes meaningful information with no fluff.

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 simple acknowledgment tool, the description covers the essential context despite lacking an output schema. It states the input source, the effect, and the access requirement. It does not describe the response format, but the action is straightforward and annotations plus schema provide adequate completeness.

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% with clear descriptions for both parameters. The description repeats that alert_id comes from list_my_alerts and note is optional, but these details are already fully captured in the schema. Thus the description adds no significant semantic value beyond the schema, warranting the baseline score.

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 clearly states the action: 'Acknowledge one of YOUR alerts' with a specific resource (alert id). It distinguishes from the sibling tool 'resolve_alert' by explicitly noting 'without resolving it', making the purpose unambiguous.

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?

It provides explicit guidance on when to use the tool: when you want to mark an alert as seen/being-handled but not resolve it. It also specifies that the alert id comes from 'list_my_alerts' and requires write scope, effectively telling the agent the prerequisite context and excluding the resolve path.

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