wireshark_verify_ssl_decryption

Read-only

Verify TLS decryption by testing pcap file against a keylog file in SSLKEYLOGFILE format to confirm successful decryption.

Instructions

[TLS] Verify TLS decryption with SSLKEYLOGFILE-format keylog file.

Input Schema

NameRequiredDescriptionDefault
pcap_fileYes
keylog_fileYes
Behavior3/5

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

Annotations already indicate readOnlyHint=true, so the tool is read-only. The description adds context about using an SSLKEYLOGFILE-format keylog file, but does not disclose what happens on failure or any side effects, which is acceptable given the annotation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One sentence with a [TLS] prefix for domain context. Efficient and front-loaded, though could be slightly expanded for clarity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema and minimal parameter descriptions. The description does not explain what the tool returns (e.g., success/failure, details), error conditions, or input format specifics beyond the keylog hint. Incomplete for a verification tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must add meaning. It clarifies that keylog_file is an SSLKEYLOGFILE-format file, but pcap_file receives no extra context beyond being a string. This is insufficient for full semantic understanding.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description specifies the action (verify) and resource (TLS decryption) with the method (SSLKEYLOGFILE-format keylog file), distinguishing it from similar sibling 'wireshark_decrypt_tls' by implying verification rather than decryption.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 like 'wireshark_decrypt_tls'. No exclusions or context for selection are provided.

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