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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds only the account-scoping context; it says nothing about pagination, result size, or ordering. With annotations carrying the load, a 3 is appropriate.

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, but the second largely restates the first ('List all the Integrations' vs 'Get the details of all Integrations available for the account'). Only the 'available for the account' scoping is new information, so the second sentence only partially earns its place.

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 read-only list tool with full annotation coverage and no output schema, the description is minimally adequate. It omits differentiation from the many integration/connector siblings, which is the one thing an agent actually needs here, leaving a real gap in an otherwise crowded namespace.

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% and the single optional 'fields' parameter is fully documented in the schema, including its enum of selectable fields. The description adds no syntax or behavioral detail beyond what the schema provides, so the baseline 3 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?

The description states a clear verb (list/get) and resource (Integrations) and scopes it to the account, so an agent knows exactly what it returns. However, it does not distinguish this from similarly named siblings such as list_crm_integrations, list_connectors, or get_connector, which an agent could easily confuse it with.

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?

There is no when-to-use guidance and no mention of alternatives. With siblings like list_crm_integrations and list_connectors in the same namespace, the description should say when this generic integration list is the right call versus those narrower ones, but it offers nothing.

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