Read-only

Get a comprehensive overview of network traffic from a pcap file: file info, protocol hierarchy, top talkers, conversations, hostnames, and anomaly detection in one call.

Behavior3/5

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

Annotations already mark readOnlyHint=true, consistent with an analysis tool. Description adds no additional behavioral traits (e.g., performance impact, data volume). It does not contradict annotations, but provides minimal extra context beyond what annotations convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence listing outputs is fairly concise, but the list is somewhat lengthy. Overall proportion seems appropriate for the tool's purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Tool has no output schema, low schema coverage, and many siblings. Description is too brief to equip an agent with full understanding of usage, output expectations, or how this differs from other tools. Incomplete for a tool that appears to be an aggregate analysis.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Input schema has one parameter 'pcap_file' with 0% coverage in description. The description does not explain the parameter beyond the schema's bare definition. With low schema coverage, the description fails to compensate by adding meaning or format details.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description specifies verb 'quick analysis' on 'pcap file' and lists outputs (file info, protocols, top talkers, conversations, hostnames, anomalies), indicating a comprehensive overview. However, it does not differentiate from sibling tools like wireshark_get_file_info or wireshark_stats_*, so clarity is good but not excellent.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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. The description labels it as 'One-call traffic overview', implying an initial summary, but lacks explicit context or exclusions regarding when to use other specific tools like wireshark_stats_* or wireshark_detect_*.

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