A3.8/5.0

Behavior4/5

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

Annotations establish it is a non-read-only, non-destructive, closed-world operation, and the description adds genuinely new behavioral context: it produces a complete affected-resource snapshot with validation, rejects raw operations, and requires explicit affected campaigns for shared resources. It does not explain that a prepare step must be followed by a confirm call, which is a notable omission but not a contradiction.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The lead sentences are front-loaded and each states a real constraint (snapshot+validation, shared-resource rule, no raw operations). The sixteen-item tool list is long but is the core routing payload and each entry is a distinct alternative, so it largely earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with a very large discriminated-union schema and no output schema, the description covers prepare semantics, constraints, and routing adequately, but omits what the prepare step returns and that a separate confirm step is required before changes take effect. Those are material gaps given the sibling *_confirm tools in the same family.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 33%, so the description carries more of the burden than usual. The list of named tools maps implicitly onto the sixteen `kind` discriminator values in the body oneOf, which is useful, but the description never mentions the `body` discriminator, the `kind` field, or the `connection_context` parameter, leaving the schema to do the work.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb+resource combination ('Prepare a typed management change') and immediately signals it is a compatibility entrypoint, which lets an agent place it relative to the many *_prepare siblings. The phrase 'typed management change' is somewhat abstract on its own, but the enumeration of the sixteen matching named tools clarifies the exact scope of change kinds it accepts.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explicitly tells the agent to prefer the matching named tool and lists all sixteen alternatives, which is strong routing guidance and effectively a 'when not to use this' statement. What it does not state is the positive condition under which this compatibility entrypoint is the right choice, so the agent must infer that it exists only for legacy/backward-compatible callers.

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