analyze_tcp_anomalies

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

With no annotations, the description carries full burden. It clearly explains the tool is purely observational, reports factual metrics, and does not attempt to diagnose. It covers its non-destructive nature and scope, though it could explicitly state it is read-only or safe.

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 well-structured with sections for args, returns, and pattern categories. It is slightly verbose but each sentence adds value. It front-loads the main purpose and is easy to parse, though a bit longer than necessary.

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?

It describes return values comprehensively, covering statistics, patterns, and summary, and lists pattern categories. However, it omits error conditions or prerequisites for the pcap_file (e.g., accessibility). Given the presence of an output schema, the description fills gaps well.

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 input schema has 0% description coverage, but the description fully compensates by explaining each parameter: pcap_file (HTTP URL or absolute local file path), server_ip and server_port (optional filters). This adds valuable meaning beyond the schema types.

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 detects TCP traffic patterns through statistical analysis and lists specific pattern categories. It differentiates itself by emphasizing observational analysis without diagnosing root causes, but does not explicitly distinguish from sibling tools like analyze_tcp_connections or analyze_tcp_retransmissions.

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 implies usage for observational pattern detection and advises against using it for diagnosis, but it does not explicitly state when to prefer this tool over siblings or provide exclusions. Better guidance on alternatives would improve it.

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