SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill automates the creation of unique byte signatures for specific instructions within executable code, enabling precise runtime patching.

Core Features & Use Cases

  • Instruction Patching: Generates signatures to locate instructions for modification (e.g., NOPing calls, altering branches).
  • Automated Signature Generation: Uses IDA Pro MCP to find the shortest unique byte signature for a given instruction address.
  • Use Case: When a game update breaks a specific function, this Skill can generate a signature to precisely target and patch the problematic instruction at runtime, restoring functionality without recompiling.

Quick Start

Use the generate-signature-for-patch skill to create a signature for the instruction at address 0x180A00E2F to skip the conditional branch.

Frequently Asked Questions about generate-signature-for-patch

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate a unique byte signature for runtime instruction patching in IDA Pro?▼

To generate a unique byte signature for runtime instruction patching, this Skill uses IDA Pro MCP to find the shortest fully-defined byte signature for a specific instruction address, validating its uniqueness against the executable's memory space.

What is the best way to locate specific instructions for modification when a game update breaks a function?▼

The best way to locate specific instructions for modification after a game update is generating a unique byte signature targeting the problematic instruction, enabling precise runtime patching to restore functionality without recompiling.

Does this signature generation approach support forward-only expansion?▼

Yes, this signature generation approach supports forward-only expansion to find the shortest unique byte signature for a specific instruction address, ensuring precise code modification in reverse engineering scenarios.

Can I use this tool to generate signatures for NOPing calls or altering conditional branches?▼

Yes, you can use this tool to generate byte signatures for instruction patching tasks such as NOPing calls or altering conditional branches by targeting specific instruction addresses within executable code.

Why does my generated byte signature fail to uniquely identify an instruction in memory?▼

A generated byte signature may fail to uniquely identify an instruction if it is not fully-defined or lacks sufficient length; this Skill validates uniqueness against the entire executable memory space to prevent mismatches.

Do I need IDA Pro MCP to automate signature creation for code modification?▼

Yes, you need IDA Pro MCP to automate signature creation for code modification, as it provides the necessary environment to analyze executable memory and validate the uniqueness of generated byte signatures.
