Update rate-limit settings

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

The '[WRITE]' marker merely restates readOnlyHint=false, which annotations already provide, so it adds no new behavioral information. Nothing is said about whether the update is a partial merge or full replacement, what happens to unspecified keys, which permissions are required, or what the response returns.

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 a single terse fragment with no filler, but this is under-specification rather than conciseness — the brevity leaves the agent with nothing actionable beyond the endpoint path already implied by 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?

For a write tool with a nested, fully open settings object, no output schema, and only safety annotations, the definition should at minimum describe the accepted settings keys or the patch semantics. Those omissions leave an agent unable to construct a correct call.

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% with two required parameters, and the 'settings' object is an unconstrained free-form map (additionalProperties: {}) with no documented keys. The description supplies no field names, no format hints, and no examples, so it does nothing to compensate for the coverage gap.

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 gives an HTTP method and resource path (PATCH /domains/{domain}/rate-limit/settings), which identifies the resource and the mutation intent, but it never states in prose what the tool actually does or how the settings differ from rate-limit rules. It does not distinguish this tool from get_rate_limit_settings or update_rate_limit_rule beyond the raw path.

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, no prerequisites, and no mention of the sibling tools (get_rate_limit_settings, update_rate_limit_rule) that an agent must choose between. The only implicit cue is the PATCH verb itself.

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