get_firewall_settings

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered and the bar is lower. The description adds nothing beyond that — it doesn't say whether it returns current active settings only, whether levels are per-profile (IPv4 vs IPv6), or what any auth/session requirement is.

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 certainly short and free of waste, but the brevity is under-specification rather than economy: a four-word fragment with a parenthetical. Adding one verb ('Retrieve current...') would cost almost nothing and materially improve it.

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?

An output schema exists, so return values needn't be explained, and annotations cover the read-only nature. Still, for a settings-retrieval tool in a crowded family of getters, the description gives no action verb and no scope qualifier, leaving the agent to infer intent from the name alone.

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?

The tool takes zero parameters, so there is no parameter semantics to explain; baseline 4 applies. The parenthetical '(IPv4/IPv6)' is the only hint and is not needed to invoke the tool.

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 the resource (firewall security levels) and scope (IPv4/IPv6), so the subject matter is identifiable, but it is a bare noun phrase with no verb — the agent must infer 'get/read' from the tool name alone. It does not distinguish itself from adjacent getters like get_remote_admin_settings or get_dmz_settings beyond the word 'firewall'.

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 when-to-use guidance, no mention of alternatives, and no exclusions are given. An agent gets no signal about whether this is the right tool versus get_dmz_settings, get_upnp_settings, or read_router_page when investigating firewall-related state.

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