deep_packet_analysis

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

Annotations already declare readOnly, idempotent, and non-destructive behavior. The description adds that the tool produces markdown tables and layer details, providing additional behavioral context beyond annotations. No contradictions.

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 front-loaded with the main purpose and then lists arguments efficiently. It is appropriately sized with no wasted sentences, though the argument format could be more compact.

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 annotations cover safety and idempotency, the description adequately explains the tool's purpose and parameters. However, it does not describe the return value structure beyond 'markdown tables,' nor does it mention any other side effects. With no output schema, this leaves some ambiguity.

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?

Despite the context signal indicating 0% schema description coverage, the description actually explains all three parameters (file_path, count, display_filter) with clear meanings and examples (e.g., 'Path to PCAP/PCAPNG file'). This adds significant value over the bare schema, so the score is high.

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 tool performs deep packet analysis with protocol breakdown, layer details, and markdown tables. It uses specific verbs and resources, and while it doesn't explicitly distinguish from siblings, the focus on 'deep' and 'protocol breakdown' sets it apart from simpler analysis tools like analyze_pcap_file.

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 explicit guidance on when to use this tool over alternatives. The description only lists arguments and does not mention prerequisites, limitations, or when not to use it. With many sibling tools for packet analysis, this lack of guidance could lead to incorrect selection.

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