Sync Firewall

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

No annotations are provided, so the description must fully disclose behavior. It only says 'Sync firewall rules to a VPS' without explaining side effects, whether it overwrites existing rules, whether the firewall must be active, or whether it is reversible. This is a minimal disclosure for a mutating operation.

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 extremely concise at one sentence of five words, front-loaded with the core action. It is efficient, though it sacrifices valuable detail; thus not a perfect score.

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?

The tool has no annotations or output schema, and the description is a single clause. It fails to clarify the operational semantics of 'sync' (e.g., does it replace all rules? does it require activation?), leaving the agent under-informed for a complex firewall action.

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 input schema already provides descriptions for both vm_id and firewall_id, covering 100% of parameters. The description adds no extra semantic information about the parameters or their relationship.

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 uses a specific verb 'sync' with explicit target 'firewall rules to a VPS'. It clearly identifies the operation's resource and destination, and distinguishes from sibling tools like vps_firewall_activate or vps_firewall_create_rule by implying a bulk replication action. However, it doesn't elaborate on what 'sync' includes, so it's not a 5.

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 use this tool versus alternatives such as vps_firewall_activate or vps_firewall_update_rule. The description simply states what it does, with no context about prerequisites, typical scenarios, or exclusions.

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