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

Annotations already declare this as a non-read-only, non-destructive mutation, and the description usefully adds that the change is Organization-wide rather than per-server. However, with both parameters optional it never explains partial-update behavior (does omitting a parameter preserve or reset it?) or whether the change is reversible, which is the key behavioral gap for a mutation.

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 front-loaded sentence with the resource named first and the two affected aspects listed after the colon. No filler, though the trailing clause is a slightly loose paraphrase of the schema.

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 two-optional-parameter mutation with no output schema, the description covers the what and the org-wide scope but omits partial-update semantics, permission requirements, and any indication of what a successful call returns or changes. Adequate but with clear gaps.

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% and both parameters already carry their own descriptions and an enum, so the schema does the heavy lifting. The description's phrasing of 'the Release Channel every upgrade follows' essentially restates the channel schema text rather than adding format, default, or interaction semantics.

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 (Change) and resource (the Organization's upgrade policy) and enumerates the two mutable aspects, so an agent can distinguish it from server_upgrade_policy_show or server_upgrade. It stops short of explicitly naming the read sibling it complements, which keeps it out of the top band.

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 or when-not-to-use guidance, no mention of prerequisites or permissions, and no reference to the closely related server_upgrade_policy_show or server_upgrade tools. The agent must infer the routing 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.
