VPS_updateFirewallRuleV1

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

The description warns that VMs with this firewall activated will lose sync and need manual re-sync, a key behavioral trait. However, no annotations exist, so the description bears full burden, yet it omits other behaviors like idempotency or error states.

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?

Three sentences, each relevant. The warning is front-loaded. No fluff, but could be more structured with bullet points.

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?

Without output schema or annotations, the description is minimal. It lacks preconditions, error handling, or return value expectations. For a tool with 6 required params, more context is needed.

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 has 100% description coverage for all 6 parameters. The description adds no additional semantics beyond what the schema already provides.

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 clearly states the verb 'Update' and the resource 'firewall rule from a specified firewall'. However, it lacks explicit differentiation from sibling tools like VPS_createFirewallRuleV1 or VPS_deleteFirewallRuleV1, though the action itself is distinct.

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 on when to use this tool versus alternatives. It does not mention prerequisites or scenarios where use of this tool is preferred over others.

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