analyze_icmp_packets

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

Discloses file input limitations and return type, but lacks explicit mention that the tool is read-only or non-destructive, though it's implied. No annotations exist to contradict.

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?

Well-structured with clear sections, but slightly verbose; could trim redundant phrasing like 'comprehensive analysis results'.

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?

Despite having an output schema, the description adequately covers input constraints and purpose, making it complete for a single-parameter 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?

With 0% schema description coverage, the description fully compensates by detailing that pcap_file must be an HTTP URL or absolute local path, and what formats are unsupported.

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?

Clearly states 'Analyze ICMP packets from a PCAP file', using a specific verb and resource, and is easily distinguishable from sibling tools that analyze other protocols like DHCP, DNS, etc.

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?

Explicitly lists supported and unsupported input formats, including a warning about Claude's file upload limitation, guiding the agent on when and how to use the tool.

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