get_packet_statistics

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does not state that the operation is read-only, does not mention error conditions or side effects, and only vaguely says 'Returns: Packet statistics' without detailing behavior beyond the operation itself.

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 a short, front-loaded docstring with a clear top-line purpose and clearly separated Args/Returns sections. Every sentence is purposeful and no filler is present.

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 the simple one-parameter interface and the presence of an output schema, the description provides enough context for basic selection and invocation. It falls short only in missing explicit caveats or when-not-to-use guidance, but overall it is complete for a simple read-analyze tool.

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 Args section adds meaning to file_path by describing it as 'Path to the PCAP file', which is absent from the schema's bare 'File Path' title. This compensates well for the 0% schema description coverage.

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 states a specific verb and resource ('Get statistics about packets in a PCAP file'), making the basic purpose clear. However, it does not distinguish this from sibling tools like analyze_pcap_file or extract_packet_details, so it misses the last bit of differentiation.

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 provides no guidance on when to use this tool versus alternatives, no exclusions, and no prerequisites. The only implicit context is that the tool is for packet statistics, but it lacks any comparison to sibling tools.

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