get_dfw_rule_stats

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

Annotations declare readOnlyHint=true, destructiveHint=false, idempotentHint=true. Description adds '[READ]' label and lists specific returned fields (packet_count, byte_count, etc.), providing good transparency beyond annotations.

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?

Description is concise with a clear one-liner followed by an args list. Front-loads the purpose, but the args section could be more structured.

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?

Given no output schema, description adequately explains return fields. Parameter semantics are weak, but for a simple read tool with self-explanatory parameter names, it is reasonably complete.

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?

Schema description coverage is 0%. Description only lists parameter names without adding meaning or constraints beyond what is in the schema (e.g., no explanation of 'target' or format requirements).

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 explicitly states 'Get packet/byte hit-count statistics for a DFW rule' and lists returned fields. Distinguishes itself from sibling tools like list_dfw_rules or get_dfw_policy by focusing on statistics.

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?

Implied usage: use this tool to retrieve statistics for a specific DFW rule. No explicit when-to-use or alternatives mentioned, leaving some ambiguity among sibling tools.

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