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

Annotations already declare destructiveHint=true, indicating mutation. The description adds that acknowledgment stops escalation/paging, but does not disclose potential side effects like not resolving the incident or whether it can be undone. The HTTP method and path are provided, which adds some transparency.

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 two sentences long, front-loaded with key verb and resource, and every sentence provides essential information. No wasted words.

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 the tool has only one parameter, no output schema, and annotations provide destructive hint, the description covers the basic action but does not mention that the incident must be in 'triggered' state to be acknowledged, nor what happens after acknowledgment. It is adequate but not fully comprehensive.

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 one parameter described. The description does not add meaning beyond the schema's own description of incidentId. Baseline 3 is appropriate since the schema already documents the parameter adequately.

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 verb 'acknowledge' and the resource 'incident', specifies it stops escalation/paging, and distinguishes it from siblings like resolve_incident by noting the action stops escalation.

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 description implies use for triggered incidents needing acknowledgment to stop paging, but does not explicitly state when not to use it or mention alternatives like resolve_incident. The context is clear but lacks explicit guidance on conditions or exclusions.

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