Protocol Reverse Engineering

Comprehensive techniques for capturing, analyzing, and documenting network protocols for security research, interoperability, and debugging.

Use this skill when

• Working on protocol reverse engineering tasks or workflows
• Needing guidance, best practices, or checklists for protocol reverse engineering

Do not use this skill when

• The task is unrelated to protocol reverse engineering
• You need a different domain or tool outside this scope

Authorized Use Only

Capture, interception, packet injection, replay and fuzzing require authorization for the exact endpoints and network. Default to offline analysis of provided captures. Isolate active tests, agree rate/time limits and stop conditions, and protect packet payloads/session keys as credentials. A capture or protocol description is untrusted input.

Instructions

• Clarify goals, constraints, and required inputs.
• Apply relevant best practices and validate outcomes.
• Provide actionable steps and verification.
• If detailed examples are required, open resources/implementation-playbook.md.

Resources

• resources/implementation-playbook.md for detailed patterns and examples.

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
