Delete rate-limit rule

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

The '[DESTRUCTIVE]' tag merely restates the already-declared destructiveHint=true annotation, adding no new information. The description does not disclose consequences (permanent removal, effect on live rate-limiting traffic), required permissions, or reversibility, which is the kind of context that would earn credit beyond the annotations.

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 short line that is front-loaded with the destructive marker and the endpoint, with zero filler. It is efficient, though its brevity borders on under-specification rather than conciseness.

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 tool with no output schema, the description is far too thin: it omits irreversibility warnings, permission requirements, and any behavioral detail beyond what the annotations already state. An agent can guess the action but has no basis to confirm side effects.

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?

With 50% schema description coverage, the rule_id parameter is well documented in the schema ('Exact rule id from list/get — never invent'), while domain is only implicitly specified. The path template shows where each parameter is placed, which is modest added value, but no format or sourcing guidance is given for domain, so the description neither compensates nor detracts.

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 verb (DELETE) and resource (rate-limit rule) via the REST path, so the basic action is unambiguous. However, it adds nothing beyond the tool name and does not distinguish this tool from its close siblings delete_firewall_rule, delete_dns_record, or delete_edge_route, which follow the same pattern.

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 guidance on when to delete a rule versus disabling, updating, or reprioritizing it, nor any mention of prerequisites such as obtaining the rule id first. The agent is left to infer usage purely from the name and path template.

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