get_conversation_stats

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

The annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true, so the safety profile is clear. The description does not add additional behavioral context (e.g., performance, side effects, requirements for the PCAP file). Without annotations, this would be lower, but with them, the description adds minimal extra value.

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 concise: a brief one-line purpose followed by parameter details in a list format. It is well-structured and front-loaded with the main functionality. Every sentence adds value, though the parameter list could be more integrated.

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 there is no output schema, the description fails to explain the return format or structure of the statistics. For a statistics tool, this is crucial for an agent to use the result correctly. Additionally, the description does not guide on choosing conv_type or any constraints. It feels incomplete despite the parameter details.

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%, so the description must explain the parameters. It does add basic explanations: file_path is 'Path to PCAP/PCAPNG file', conv_type is mentioned with options (eth, ip, ipv6, tcp, udp), and display_filter is 'Optional Wireshark display filter'. This is helpful but not exhaustive (e.g., default for conv_type is not explained, but the schema shows default 'ip'). It does not clarify the expected format or behavior of the display filter.

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 it provides IP/TCP/UDP/Ethernet conversation statistics from a PCAP file. It specifies the resource (PCAP file) and the action (get conversation statistics), though it could be more specific about what statistics are included. It somewhat distinguishes from siblings like follow_tcp_stream or get_packet_summary, but not explicitly.

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?

The description does not provide any guidance on when to use this tool versus alternatives. No when-to-use or when-not-to-use statements are given, and no mentioning of alternatives. The agent must infer from the purpose alone.

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