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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is fully covered. The description adds no behavioral context beyond restating the read nature, and does not clarify what 'per installation' means when the only parameters are company and environment.

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?

A single sentence with no redundancy, but it is essentially the title repeated rather than a front-loaded value statement. Minimal size without corresponding information gain.

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?

With no output schema, the description partially compensates by naming one return aspect ('whether the managed runtime is enabled'), but it does not describe the rest of the settings returned or the relationship between company/environment and an installation. Minimal but arguably callable.

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 description coverage is 100% with only two required parameters, so the schema fully documents company UUID and environment enum. The description adds no additional meaning about how these parameters identify the installation, making 3 the appropriate baseline.

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 verb ('Read') and resource ('assistant settings') plus a scope ('per installation'), which is more than a bare name restatement. However, it is near-verbatim identical to the title, and the only sibling differentiation is implied by contrast with summer_messenger_assistant_update.

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 indication of when to use this tool versus the update sibling, no prerequisites, and no exclusions. The agent must infer usage entirely from the name.

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