delete-deny-rule

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

With no annotations, the description carries the full burden. It explicitly discloses that this is a write operation that 'changes PCE state' and warns about the approval pause in gated clients, advising against retries. This is valuable non-obvious behavior. It doesn't cover side effects or error cases, but for a single-parameter delete it is strong.

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 sentences with no filler. The purpose is front-loaded, and the critical operational warning follows immediately. Every word earns its place; the all-caps 'WRITE OPERATION' is a minor stylistic choice that doesn't harm clarity.

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 simple tool with one parameter and no output schema, the description sufficiently covers what it does and the most important runtime behavior (approval gating). Explicit return-value semantics would be nice but are not necessary given the simplicity and absence of an output schema.

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 coverage is 100%: the href parameter is fully described with an example path format. The description merely restates 'by its href' without adding new detail, so it meets the baseline but does not exceed it.

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 states a specific verb ('Delete'), a specific resource ('deny rule from a ruleset'), and a selection mechanism ('by its href'). This clearly differentiates it from sibling tools like delete-sec-rule or delete-ruleset without needing to open schemas.

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 context is clear: use this when deleting a deny rule. It does not explicitly name alternatives (e.g., update-deny-rule for modification), but the operation is unambiguous given the sibling set. The approval-gating note provides additional operational context, though it is more about behavior than tool selection.

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