recurrent_payments_update_recurrent_payment_config

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

Annotations already declare readOnlyHint=false, destructiveHint=true, idempotentHint=false and openWorldHint=true, so the safety profile is covered by structured data. The description adds nothing beyond that: it does not say what is overwritten, whether the body replaces the whole config or merges fields, nor whether missing fields are preserved or cleared - a critical gap for a destructive PATCH.

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?

It is short and front-loaded with no filler, but the brevity comes from under-specification rather than efficiency. The endpoint line is the only content beyond the name.

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?

This is a destructive mutation on a nested object body with no output schema and no annotations explaining consequences, so the description should carry the burden - and it does not. An agent cannot tell from this text whether the update is a full replacement, what happens to omitted fields, or what errors to expect.

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 reported as 0% at the parameter level, so the description must compensate for the single nested body parameter, and it says nothing about it. The only meaning an agent gets comes from the nested property descriptions inside the schema, not from the description text.

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 reads 'Recurrent payments update recurrent payment config' plus the HTTP route, which essentially restates the tool name. The PATCH path hints that this modifies configuration, but it does not say what configuration is being changed or how it differs from the sibling create/get config tools.

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 guidance at all: no mention of when to call this versus recurrent_payments_create_recurrent_payment_config or get_current_recurrent_payment_config, and no prerequisites such as requiring an existing config. The agent must infer the usage 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.
