rmfw_rule

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

With no annotations, the description must fully disclose behavior. It mentions optional apply changes, but does not explain what 'apply' entails (e.g., immediate effect, rollback), nor does it describe potential side effects like breaking connectivity or dependencies.

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?

The description is a single sentence that is efficient and front-loaded with the main action. No extraneous words.

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 deletion tool with 2 parameters and no output schema, the description is too sparse. It lacks context about the behavior when apply is false, prerequisites (e.g., rule existence), and relation to other firewall tools.

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?

Input schema has 100% description coverage for both parameters. The description adds minimal value beyond the schema by restating the apply parameter's optional nature. It does not elaborate on rule_uuid format or constraints.

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 'Delete a firewall rule and optionally apply changes' clearly states the verb (delete) and resource (firewall rule). Among siblings like mkfw_rule (create) and set_fw_rule (update), this is the only delete tool, so it effectively distinguishes itself.

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?

No guidance is provided on when to use this tool versus alternatives, such as set_fw_rule or toggle_fw_rule. There is no mention of prerequisites, consequences of deletion, or when not to use it.

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