**The reverse-skill repository defines ten distinct expert roles—including Red-Team, Blue-Team, Purple-Team, and Malware Analyst—that govern how its skill-routing engine authorizes and dispatches security operations based on user intent and platform constraints.**

The `zhaoxuya520/reverse-skill` project implements a **role-based access control** system where **reverse-skill expert roles** determine which skill modules users can invoke. These specializations are formally documented in [`skills/ops/role-map.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/ops/role-map.md) and enforced through the routing configuration in [`skills/config/routing.json`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/config/routing.json), ensuring that sensitive operations remain restricted to authorized personnel.

## How the Role Map Structures Expert Permissions

In [`skills/ops/role-map.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/ops/role-map.md), the repository categorizes security practitioners into distinct operational personas. Each role encapsulates specific capabilities, toolsets, and authorization boundaries that the routing engine uses to enforce **hard gate** controls—preventing unauthorized actions like live network scans or credential-borne operations from inappropriate contexts.

## The 10 Expert Roles Defined in reverse-skill

### Red-Team / Offensive Security

**Red-Team** operators simulate attackers to discover exploitable weaknesses. Their typical tasks include exploit development, penetration testing, reverse-engineering binaries, and crafting payloads. This role requires elevated privileges for offensive operations.

### Blue-Team / Defensive Security

**Blue-Team** personnel focus on detecting, responding to, and mitigating security incidents. They perform log analysis, threat hunting, digital forensics, and execute incident-response playbooks according to [`skills/ops/role-map.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/ops/role-map.md).

### Purple-Team / Hybrid

**Purple-Team** members bridge offensive and defensive disciplines to improve detection capabilities. They design detection rules derived from attack techniques and conduct joint exercises that validate both offensive exploits and defensive countermeasures.

### Threat-Intelligence Analyst

This role focuses on gathering, analyzing, and disseminating adversary information. Analysts research threat actors, map techniques to the ATT&CK framework, and produce intelligence briefs that inform other roles.

### Reverse-Engineering Engineer

**Reverse-Engineering Engineers** perform deep binary analysis and de-obfuscation. They conduct static and dynamic analysis of ELF/PE files using tools like Ghidra, IDA Pro, and radare2 as specified in the role capabilities matrix.

### Malware Analyst

**Malware Analysts** dissect malicious software to understand behavioral patterns. Their workflow includes sample triage, sandbox execution, and authoring YARA rules for signature-based detection.

### Incident Responder

**Incident Responders** provide rapid containment and remediation of security events. They perform triage, evidence collection, root-cause analysis, and remediation planning during active security incidents.

### Security Researcher

**Security Researchers** explore novel vulnerabilities and attack vectors. They develop proof-of-concept exploits, publish security advisories, and manage vulnerability disclosure processes.

### CTF Participant / Challenge Designer

This role involves creating and solving capture-the-flag challenges. Participants design realistic challenge scenarios, write exploit scripts, and build competition infrastructure for training exercises.

### Tool-Builder / Automation Engineer

**Tool-Builders** develop reusable security tooling and automation pipelines. They write scripts, maintain CI/CD pipelines for security assets, integrate APIs, and manage sandbox environments.

## Role-Based Routing Implementation

The routing engine references [`skills/config/routing.json`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/config/routing.json) to match user hints against authorized **reverse-skill expert roles**. When a user requests an operation, the system checks the role map to verify that the requested action aligns with the user's assigned specialization.

```json
{
  "hint": "enumerate AD secrets",
  "role": "Red-Team",
  "platform": "windows",
  "skill": "AD-enumeration"
}

```

Entry point scripts located in `skills/scripts/` handle the dispatch logic. **[`master-route.sh`](https://github.com/zhaoxuya520/reverse-skill/blob/main/master-route.sh)** serves Linux and macOS environments, while **`master-route.ps1`** handles Windows execution. Both scripts accept `--role` or `-Role` parameters to enforce the hard-gate restrictions defined in [`RULES.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/RULES.md).

## Practical Code Examples for Role Selection

To invoke a role-specific module from the command line, specify the expert role using the appropriate script for your platform.

On Linux or macOS:

```bash
bash skills/scripts/master-route.sh --hint "run malware analysis" --role "Malware Analyst"

```

On Windows:

```powershell
powershell -NoProfile -ExecutionPolicy Bypass -File skills/scripts/master-route.ps1 -Hint "investigate suspicious logins" -Role "Blue-Team"

```

These commands trigger the routing engine to validate the role against [`RULES.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/RULES.md) before executing the corresponding skill module.

## Summary

- The `zhaoxuya520/reverse-skill` repository defines **ten distinct expert roles** ranging from Red-Team to Tool-Builder specializations.
- Role definitions reside in [`skills/ops/role-map.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/ops/role-map.md) and enforce **hard-gate authorization** rules specified in [`RULES.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/RULES.md).
- The routing configuration in [`skills/config/routing.json`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/config/routing.json) maps user intents to authorized roles.
- **[`master-route.sh`](https://github.com/zhaoxuya520/reverse-skill/blob/main/master-route.sh)** and **`master-route.ps1`** serve as cross-platform entry points for role-based skill dispatch.
- Each role encapsulates specific operational boundaries that prevent unauthorized access to sensitive security functions.

## Frequently Asked Questions

### Where are the reverse-skill expert roles documented?

The expert roles are formally defined in **[`skills/ops/role-map.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/ops/role-map.md)**. This file contains the complete capability matrix describing the ten security specializations and their respective operational boundaries.

### How does the hard-gate authorization model restrict user actions?

According to **[`RULES.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/RULES.md)**, the hard-gate mechanism verifies the user's assigned role from [`skills/ops/role-map.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/ops/role-map.md) before permitting access to sensitive operations. This prevents users without Red-Team or Incident Responder credentials from invoking live network scans or credential-borne functions.

### What distinguishes the Purple-Team role from Red-Team and Blue-Team roles?

While Red-Team focuses exclusively on offensive operations and Blue-Team handles defensive monitoring, the **Purple-Team** role bridges both disciplines. Purple-Team members use insights from attack simulations to design detection rules and validate defensive controls, effectively translating offensive techniques into defensive signatures.

### Which scripts handle role-based skill routing in the repository?

The **[`skills/scripts/master-route.sh`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/scripts/master-route.sh)** script manages role dispatch on Linux and macOS systems, while **`skills/scripts/master-route.ps1`** performs the same function on Windows. Both scripts accept a `--role` or `-Role` parameter that the routing engine validates against [`skills/config/routing.json`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/config/routing.json) before execution.
