Which Routing Rule Handles IDA Pro Reverse Engineering in reverse-skill?

The routing rule is defined in skills/config/routing.json and maps hints matching the regex pattern \bida\b|decompile|disassembl|... to the ida-reverse/SKILL.md skill.

The zhaoxuya520/reverse-skill repository uses a JSON-based routing configuration to dispatch reverse engineering tasks to specialized skill handlers. When an analyst submits a hint containing IDA Pro keywords, the routing engine evaluates it against a specific must condition that targets IDA-specific terminology.

Routing Rule Configuration

According to the source code in skills/config/routing.json, the IDA Pro routing rule is identified by its target skill path and its matching pattern. The rule is located approximately at line 52 within the configuration array.

The Must Regex Pattern

The rule employs a must regex designed to catch IDA Pro and reverse engineering terminology. The pattern includes:

• \bida\b – word-boundary match for "ida"
• decompile and disassembl – core IDA operations
• Chinese equivalents: 反编译 (decompile) and 反汇编 (disassemble)
• Binary format indicators: \.so, \.elf, and jni

When the routing engine processes a hint, it checks for the presence of any these keywords. If the regex matches, the hint is classified for IDA Pro processing.

Skill Target Mapping

Upon successful pattern matching, the routing rule resolves the request to "skill": "ida-reverse/SKILL.md". This file contains the skill definition that implements the actual IDA Pro reverse engineering workflow, including decompilation and disassembly instructions.

Entry Point Scripts

The routing system is invoked through platform-specific master scripts that parse hints and query routing.json:

• skills/scripts/master-route.ps1 – PowerShell implementation for Windows environments
• skills/scripts/master-route.sh – Bash implementation for Linux and macOS

These scripts accept a hint argument, evaluate it against the routing rules, and execute the corresponding skill file.

Practical Usage Examples

# Windows: Route a hint for IDA decompilation

powershell -NoProfile -ExecutionPolicy Bypass -File skills/scripts/master-route.ps1 -Hint "IDA decompile libnative.so"

# Linux/macOS: Route a hint for ELF disassembly

bash skills/scripts/master-route.sh --hint "disassemble ELF binary with IDA"

Both commands trigger the routing rule in skills/config/routing.json, match the hint against the IDA-related regex, and invoke ida-reverse/SKILL.md.

Summary

• The routing rule resides in skills/config/routing.json and uses a must regex to identify IDA Pro requests
• Matching hints route to ida-reverse/SKILL.md for skill execution
• Entry points are master-route.ps1 (Windows) and master-route.sh (Unix)
• Trigger keywords include "ida", "decompile", "disassembl", .so, .elf, jni, and Chinese reverse engineering terms

Frequently Asked Questions

What file defines the IDA Pro routing rule?

The rule is defined in skills/config/routing.json within the zhaoxuya520/reverse-skill repository. This file contains the must regex pattern and the mapping to ida-reverse/SKILL.md.

Which regex patterns activate the IDA Pro skill?

The routing rule activates when hints contain \bida\b, decompile, disassembl, 反编译, 反汇编, \.so, \.elf, or jni. These patterns cover common IDA Pro operations and binary formats.

How do I manually trigger the IDA Pro routing?

Use the master route scripts with a hint containing IDA keywords:

• Windows: powershell -File skills/scripts/master-route.ps1 -Hint "your IDA hint"
• Unix: bash skills/scripts/master-route.sh --hint "your IDA hint"

Can I extend the routing rule to include additional IDA terms?

Yes. Modify the must regex in skills/config/routing.json to include additional patterns. The routing engine applies these changes immediately to subsequent hints without requiring updates to the skill definition in ida-reverse/SKILL.md.
