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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered structurally. The description adds genuinely new context by disclosing that resuming requires an approved plan, but it does not state what pausing actually disables (live storefront checkout? a single rule?), whether it takes effect immediately, or whether it is reversible without that approval.

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 clauses, verb front-loaded, with no filler. It is efficient, though the terseness tips into under-specification rather than tight completeness.

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 destructive mutation with three undocumented parameters and no output schema, the description is too thin. An agent cannot tell the blast radius of a pause, what the response returns, or how to specify which rule or reason before acting destructively.

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 0% across three parameters, so the description must carry the semantic load and largely fails. The 'checkout/rules' phrasing hints that 'rule' targets a single rule versus workspace-wide scope, but 'reason' and the UUID format of 'rule' are left entirely unexplained.

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 ('Pause') and resource scope ('checkout/rules'), which an agent can distinguish from siblings like checkout_get, checkout_manage, and checkout_plan_edit. It stops short of explicitly naming those alternatives, so it is clear but not fully differentiated.

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 only usage-like content is the precondition 'approved plan required to resume', which is a state requirement rather than a when-to-use rule. It never says when to pause versus using checkout_manage or checkout_plan_edit to change settings, nor what conditions justify pausing.

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