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

Annotations already establish the safety profile (readOnlyHint=true, idempotent, non-destructive, closed-world), so those traits need no restating. The description does add one piece of domain context — that these entries originated from a simulation — but says nothing about pagination, ordering, or scope of the returned set.

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 filler that leads directly with the resource and its state. Every word earns its place, and nothing important is buried.

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?

An output schema exists, so return values need not be explained, and the read-only annotations cover safety. For a no-parameter list tool the description is nearly sufficient; only the relationship to the action-handling siblings is left unstated.

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?

The tool takes zero parameters, so the baseline of 4 applies. There is nothing for the description to disambiguate, and it introduces no misleading parameter framing.

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 names a specific resource and its state: changes that were simulated and now await human approval or rejection. That is more precise than a restated title, but it never names the sibling tools (get_action, manage_action) that operate on the same objects, so an agent gets resource clarity without differentiation.

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 phrase 'waiting for a person to approve or reject' implies its place in an approval workflow, which is useful implied context. However, it names no alternatives (get_action, manage_action) and states no explicit when-to-use or when-not-to-use condition.

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