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

Annotations already declare readOnlyHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is covered structurally. The description adds one genuinely new behavioral fact — that this is an admin-level read — but does not say whether credentials/secrets are surfaced, whether the call hits live provider APIs, or how failures per provider are reported.

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 no filler; the verb and scope come first and the admin qualifier last. It is efficient, though the parenthetical '(admin)' is terse enough to be slightly cryptic.

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 should convey what a 'status' result looks like (connection state, webhook health, errors per provider), and it doesn't. Combined with the undocumented workspace parameter and 0% schema coverage, the definition is minimally viable but leaves gaps an agent must discover by calling.

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%, so the description must carry parameter meaning, and it only partly does. It enumerates the provider categories that correspond to the 'sections' enum, but those values are already self-documenting in the schema, while the required 'workspace' parameter is left ambiguous ('per environment' conflates workspace with environment) and the default behavior when 'sections' is omitted is unstated.

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 ('Read') plus the concrete resource: payment provider and webhook status across Stripe, PayPal, Stripe Billing, Digistore24 and partner webhooks, scoped per environment. This is clearly distinguishable from the write-side sibling payments_update, though it doesn't explicitly name that sibling.

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 '(admin)' marker implies a privileged read context and 'per environment' implies scoping, but there is no explicit statement of when to use this versus payments_update, billing_get, stripe_checkout_purchases_get, or subscriptions_list. Usage is only implied by the read-only phrasing.

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