analyze_traffic_flow

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

With no annotations, the description must disclose behavioral traits. It states the tool 'Analyzes' and returns results, but does not mention whether it modifies any state, requires special permissions, or has rate limits. As a read-only analysis tool, safety is implied but not explicit. This lack of transparency could leave an agent uncertain about side effects.

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 concise with a clear one-line summary followed by structured args and returns sections. It avoids unnecessary detail but is slightly repetitive with the schema (e.g., required field mentioned). Overall, it is efficient and front-loaded.

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?

For a tool with 3 parameters and a detailed output schema, the description is complete: it explains input semantics and output structure (structured dictionary with specific fields). The presence of a described return object compensates for the lack of an explicit output schema. No additional context is necessary.

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?

Schema description coverage is 0%, so the description fully explains each parameter: pcap_file is 'HTTP URL or absolute local file path', server_ip is 'Server IP address (required)', server_port is 'Optional filter for server port'. This adds essential meaning beyond the schema's type definitions.

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's purpose: 'Analyze bidirectional traffic flow characteristics' and lists specific outputs (traffic direction, asymmetry, RST sources, data transfer patterns). It is distinct from sibling tools like analyze_dns_packets or analyze_tcp_connections, focusing on overall flow rather than specific protocols or anomalies.

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 does not explicitly state when to use this tool versus alternatives. It implies usage for general traffic flow analysis, but lacks guidance on exclusions or scenarios where siblings (e.g., analyze_tcp_retransmissions) would be more appropriate. The context is clear but not exhaustive.

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