merge_pcap_files

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

Annotations indicate idempotence and non-destructiveness, but the description adds minimal behavioral context. It does not explain file overwrite behavior, error handling, or the effect of the 'chronological' flag beyond its basic definition.

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 extremely concise: one sentence for purpose followed by a simple Arg list. No redundant information, and the most important information appears first.

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 no output schema, the description adequately covers inputs and behavior for a straightforward merge operation. It lacks mention of return value (the created file) but is otherwise complete.

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 compensates by explaining parameter semantics: filepaths are lists, output_file expects .pcap/.pcapng, chronological controls timestamp order. However, it could clarify that filepaths must be existing valid PCAP files.

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 action 'Merge multiple PCAP files into one' using a specific verb and resource. It distinguishes itself from sibling tools like 'diff_pcap_files' or 'analyze_pcap_file' by focusing solely on merging.

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 on when to use this tool versus alternatives. It does not mention prerequisites, limitations, or scenarios where other tools (e.g., 'diff_pcap_files') might be more appropriate.

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