enable_firewall

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

No annotations provided; description discloses activation but fails to mention potential side effects (e.g., network disruption, required permissions). Minimal behavioral disclosure beyond stating the action.

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?

Single sentence with no wasted words. Information is front-loaded and immediately clear.

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?

Adequate for a simple 0-parameter tool. Description states what the tool does, and output schema exists so return values need not be explained. Some might want warnings about disrupting active connections, but overall sufficient.

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?

No parameters, so schema coverage is 100%. Description adds context by specifying 'nftables firewall ruleset', which adds meaning beyond the empty schema. Baseline 4 is appropriate.

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?

Description uses specific verb 'Activate' and resource 'nftables firewall ruleset', clearly distinguishing it from sibling tools like disable_firewall and replace_firewall_rules.

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?

Implies usage when firewall needs to be enabled, but no explicit guidance on when not to use it or prerequisites. Sibling tool 'disable_firewall' indicates toggle usage, but description lacks exclusions.

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