load_pcap

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

With no annotations, the description carries the full burden of behavioral disclosure. It only mentions the return of a session ID but fails to disclose potential side effects, resource usage, session lifecycle, or error handling. It does not mention how max_packets affects loading or whether the file is fully read into memory.

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 single, direct sentence with no unnecessary words. It is efficiently front-loaded with the primary action and outcome, making it easy to parse. Every word earns its place.

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 that initializes session state, the description is too sparse. It doesn't explain that the returned session ID is required by sibling analysis tools, how max_packets affects the loaded data, or what happens if the file is invalid. Given there is no output schema, more context is necessary for an agent to use this tool effectively.

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 description does not mention parameters; however, the input schema fully describes both pcap_path and max_packets (including their descriptions and defaults). Since schema coverage is 100%, the description adds no additional parameter context beyond what the schema already provides, matching the baseline of 3.

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 loads a PCAP file and returns a session ID, with a specific verb ('Load') and resource ('PCAP file'). It distinguishes itself from sibling tools like list_pcaps or capture_packets by its loading action and explicit outcome of a session ID.

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 guidance is given on when to use this tool versus alternatives, nor any prerequisites or follow-up steps. The phrase 'for analysis' hints at its role but doesn't explicitly mention that the returned session ID is needed by other analysis tools or that this is the entry point for PCAP processing.

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