wireshark_extract_fingerprints

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

Annotations declare readOnlyHint=true, which matches extraction. The description adds behavioral context: it uses local fingerprint files and provides a caveat about JA3 interpretation. No contradictions.

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 two sentences, compact and direct. Every sentence adds value: one states the action and outcome, the other provides important context and a caution.

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?

No output schema is provided, and the description does not mention return value format or structure. The limit parameter is undocumented. However, the core extraction purpose and behavioral notes are covered. Incomplete for a tool that likely returns a list of fingerprints.

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 coverage is 0%, and the description does not explain any parameters. The required pcap_file and optional limit are not mentioned. Parameter semantics are left entirely to the schema, which has no descriptions.

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 extracts JA3 and JA3S TLS fingerprints, which is a specific verb and resource. It distinguishes from sibling extract tools like extract_credentials and extract_dns_queries by focusing on TLS fingerprints.

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 explains that matches are against local fingerprint files and warns that JA3 identifies a TLS configuration, not an application, so treat matches as leads. It gives context for when to use, though it doesn't explicitly state when not to use.

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