How Many Core Skill Modules Are Tracked in reverse-skill?

The reverse-skill repository tracks exactly 23 core skill modules, each representing a distinct cybersecurity or reverse-engineering domain with its own SKILL.md documentation file.

The reverse-skill project (maintained at zhaoxuya520/reverse-skill) organizes penetration testing, malware analysis, and reverse-engineering knowledge into modular, routable skill units. Understanding how these modules are enumerated helps developers and security researchers navigate the repository's structured learning paths.

Where the 23 Core Skill Modules Are Defined

The authoritative count resides in skills/scripts/verify-routing-coherence.ps1. This PowerShell validation script contains a $trackedSkills array (lines 195–217) that declares every core module the routing engine recognizes.

Each entry follows this pattern:

@{ N = 'identifier'; Sub = 'path/to/SKILL.md' }

The N property provides a short routing key, while Sub points to the module's documentation. This array is the single source of truth for module enumeration—no other file in the repository overrides this count.

Complete List of Core Skill Modules

Based on the source code in verify-routing-coherence.ps1, the 23 tracked modules cover:

• Reverse engineering domains: dsl (DSL/VM), apk (Android APK), ghidra (Ghidra workflow), protocol (network protocols), extension (browser extensions), macos (macOS binaries), thick (thick clients), gorust (Go/Rust binaries), hw (hardware security)
• Offensive security: malware (analysis), pentest (tools), attack (kill chains), ad (Windows Active Directory), wifi (wireless attacks)
• Infrastructure & cloud: cloud (Kubernetes/container escape), ot (ICS/OT systems), db (database security), email (email security), sso (identity federation), sdr (software-defined radio)
• Defensive operations: forensics (digital forensics), codeaudit (source code review), hunt (threat hunting)

How to Programmatically Verify the Count

You can reproduce the module count using this PowerShell snippet derived directly from the repository's validation logic:

$coreSkills = @(
    @{ N = 'dsl';        Sub = 'reverse-engineering/dsl-vm-reverse/SKILL.md' },
    @{ N = 'apk';        Sub = 'apk-reverse/SKILL.md' },
    @{ N = 'malware';    Sub = 'malware-analysis/SKILL.md' },
    @{ N = 'pentest';    Sub = 'pentest-tools/SKILL.md' },
    @{ N = 'attack';     Sub = 'attack-chain/SKILL.md' },
    @{ N = 'protocol';   Sub = 'protocol-reverse/SKILL.md' },
    @{ N = 'ghidra';     Sub = 'ghidra-reverse/SKILL.md' },
    @{ N = 'cloud';      Sub = 'cloud-k8s/SKILL.md' },
    @{ N = 'ad';         Sub = 'windows-ad/SKILL.md' },
    @{ N = 'forensics';  Sub = 'digital-forensics/SKILL.md' },
    @{ N = 'codeaudit';  Sub = 'code-audit/SKILL.md' },
    @{ N = 'hunt';       Sub = 'threat-hunting/SKILL.md' },
    @{ N = 'ot';         Sub = 'ot-ics/SKILL.md' },
    @{ N = 'wifi';       Sub = 'wifi-wireless/SKILL.md' },
    @{ N = 'extension';  Sub = 'browser-extension-reverse/SKILL.md' },
    @{ N = 'macos';      Sub = 'macos-reverse/SKILL.md' },
    @{ N = 'thick';      Sub = 'thick-client/SKILL.md' },
    @{ N = 'gorust';     Sub = 'go-rust-reverse/SKILL.md' },
    @{ N = 'hw';         Sub = 'hardware-security/SKILL.md' },
    @{ N = 'db';         Sub = 'database-security/SKILL.md' },
    @{ N = 'email';      Sub = 'email-security/SKILL.md' },
    @{ N = 'sso';        Sub = 'identity-federation/SKILL.md' },
    @{ N = 'sdr';        Sub = 'radio-sdr/SKILL.md' }
)

Key Files Supporting Module Tracking

File	Purpose
skills/scripts/verify-routing-coherence.ps1	Contains the canonical $trackedSkills array with all 23 entries
skills/scripts/master-route.ps1	Routes user queries to the appropriate SKILL.md based on intent matching
skills/INDEX.md	Auto-generated index aggregating module metadata
skills/apk-reverse/SKILL.md	Example module documentation for Android reverse engineering
skills/cloud-k8s/SKILL.md	Example module for cloud/container security techniques

The coherence between verify-routing-coherence.ps1 and master-route.ps1 ensures that every tracked module has a routable path and valid documentation.

Summary

• 23 core skill modules are tracked in reverse-skill
• The definitive enumeration lives in skills/scripts/verify-routing-coherence.ps1
• Each module maps a short identifier to a SKILL.md file path
• Modules span reverse engineering, offensive security, cloud infrastructure, and defensive operations
• The routing system validates that all 23 modules have coherent, loadable documentation

Frequently Asked Questions

Can I add a 24th core skill module to reverse-skill?

Yes. To add a new module, append an entry to the $trackedSkills array in verify-routing-coherence.ps1, create the corresponding SKILL.md file in skills/<module-name>/, then run the verification script to ensure routing coherence passes.

What happens if a module is listed in $trackedSkills but its SKILL.md is missing?

The verify-routing-coherence.ps1 script will fail validation. It explicitly checks that every Sub path resolves to an existing file, preventing broken routing in master-route.ps1.

Is the module count of 23 documented anywhere else in the repository?

The skills/INDEX.md file reflects this count indirectly—it aggregates metadata from all discovered SKILL.md files. However, verify-routing-coherence.ps1 remains the authoritative source because it actively validates rather than merely indexes.

Do all 23 modules follow the same documentation structure?

Yes. Each SKILL.md uses standardized front-matter (title, description, difficulty, prerequisites) parsed by the indexing system. The coherence validator checks for required fields to ensure consistency across the 23 core skill modules.
