**The authorization gate mechanism in reverse-skill is a mandatory, non-bypassable security checkpoint that requires `auth.status=granted` and a valid `network_profile` in the case scope before any target interaction (ACT) can occur, enforced through policy documents, initialization scripts, and runtime guards.**

The reverse-skill repository implements a strict authorization gate mechanism to prevent accidental or unauthorized operations against live systems. According to the source code in [`RULES.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/RULES.md) and the automation scripts in `skills/scripts/`, every workflow must pass through a documented permission checkpoint before execution. This design ensures that penetration testing, CTF sandboxes, and routing operations cannot proceed without explicit administrative approval recorded in the case scope.

## Policy Foundation: RULES.md and the Authorization Contract

The authorization gate mechanism originates in the project's security policy documentation. In [`RULES.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/RULES.md) (and its Chinese counterpart [`RULES_zh.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/RULES_zh.md)), the policy explicitly states that `auth.status=granted` plus a valid `network_profile` (or authorized offline sample) must be present before any ACT.

This policy appears at multiple critical points in the file, including lines 20, 157, and 391, establishing the single source of truth for gate logic. The documentation explicitly clarifies that `-Force` or `--force` flags **never bypass** this gate, ensuring hard enforcement regardless of execution context.

## Case Initialization: Creating the Authorization Scope

The `case-init` scripts serve as the factory for authorized work environments. Located at `skills/scripts/case-init.ps1` for Windows and [`skills/scripts/case-init.sh`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/scripts/case-init.sh) for Linux/macOS/Kali systems, these scripts generate the `work/<case>/` directory structure containing a [`scope.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/scope.md) file.

During initialization, the scripts create the mandatory [`scope.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/scope.md) with empty fields that must be manually or programmatically completed:

- `auth.status` — Must be set to `granted`
- `network_profile` — Must contain a legal network identifier or authorized offline sample reference

According to [`AGENTS.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/AGENTS.md), these scripts represent the first required step in any workflow, ensuring that no case exists without the structural foundation for authorization tracking.

## Runtime Enforcement: The case-guard Scripts

The `case-guard` scripts act as the runtime enforcement layer for the authorization gate mechanism. Implemented in both PowerShell (`skills/scripts/case-guard.ps1`) and Bash ([`skills/scripts/case-guard.sh`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/scripts/case-guard.sh)), these utilities inspect the current case's [`scope.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/scope.md) before allowing any operation to proceed.

The guards perform the following validation checks:

- Verify that `auth.status` equals `granted`
- Confirm that `network_profile` exists and contains valid data
- Abort execution with error messages if either requirement is missing
- Explicitly ignore `-Force` flags to prevent bypass attempts

These scripts are invoked automatically by primary routing scripts, as documented in [`AGENTS.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/AGENTS.md) and implemented in `skills/scripts/test-p0-friction.ps1`, creating a mandatory chokepoint for all operations.

## Scope Contract Validation

The [`skills/ops/scope-contract.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/ops/scope-contract.md) file defines the formal checklist that validates a properly authorized scope. This contract explicitly requires `auth.status = granted` as a prerequisite condition, providing both automated scripts and human reviewers with an unambiguous verification standard.

Individual skill implementations, including [`skills/routing.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/routing.md), [`skills/pentest-tools/SKILL.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/pentest-tools/SKILL.md), and [`skills/ctf-sandbox/SKILL.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/ctf-sandbox/SKILL.md), reinforce this contract in their "NOW" blocks. Each skill's entry point checks the authorization status and refuses to continue without valid scope documentation.

## Practical Workflow: Passing the Authorization Gate

Implementing the authorization gate mechanism requires following a strict three-step workflow before executing any target interaction.

### Step 1: Initialize the Case

First, create a properly scoped working directory using the platform-appropriate initialization script:

```powershell

# Windows PowerShell initialization

powershell -File skills/scripts/case-init.ps1 -CaseRoot work\my-case

```

```bash

# Linux/macOS/Kali initialization

bash skills/scripts/case-init.sh --case-root work/my-case

```

### Step 2: Grant Authorization

Edit the generated `work/<case>/scope.md` file to set the required authorization fields:

```markdown
auth.status = granted
network_profile = corporate-vpn

```

Without these explicit values, the gate remains closed to all subsequent operations.

### Step 3: Execute Through the Guard

Any subsequent action automatically invokes the guard. Manual verification can be performed using:

```powershell

# Windows verification

powershell -File skills/scripts/case-guard.ps1 -CaseRoot work\my-case

```

```bash

# Linux/macOS verification

bash skills/scripts/case-guard.sh --case-root work/my-case

```

If `auth.status` is not granted or the network profile is missing, the script exits immediately with an authorization error, preventing any downstream execution.

## Bypass Resistance and Security Guarantees

The authorization gate mechanism implements defense-in-depth by ignoring compatibility flags that might otherwise override safety checks. The `-Force` and `--force` parameters, while accepted for interface consistency, **do not** override the authorization requirements enforced by `case-guard` scripts.

This design creates both static enforcement (through documentation in [`RULES.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/RULES.md) and checklists in [`scope-contract.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/scope-contract.md)) and dynamic enforcement (through runtime validation in `case-guard`). No code path in the repository can execute against a live target without the explicit `auth.status=granted` marker and valid network context.

## Summary

- The **authorization gate mechanism** requires `auth.status=granted` and a valid `network_profile` before any ACT can execute against targets.
- **Policy enforcement** originates in [`RULES.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/RULES.md) (lines 20, 157, 391) and propagates through all skill documentation.
- **Case initialization** scripts (`case-init.ps1` and [`case-init.sh`](https://github.com/zhaoxuya520/reverse-skill/blob/main/case-init.sh)) create the mandatory [`scope.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/scope.md) structure in `work/<case>/`.
- **Runtime guards** (`case-guard.ps1` and [`case-guard.sh`](https://github.com/zhaoxuya520/reverse-skill/blob/main/case-guard.sh)) validate authorization at execution time and cannot be bypassed with `-Force` flags.
- The **scope contract** defined in [`skills/ops/scope-contract.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/ops/scope-contract.md) provides the formal verification checklist used by both automated tools and human reviewers.

## Frequently Asked Questions

### What happens if I try to run a command without initializing a case?

The `case-guard` scripts will abort execution immediately. According to the source code in [`skills/scripts/case-guard.sh`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/scripts/case-guard.sh) and `skills/scripts/case-guard.ps1`, the scripts check for the existence of [`scope.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/scope.md) with valid `auth.status` before allowing any routing or operational scripts to proceed. Without initialization via `case-init`, the required files do not exist, triggering an authorization failure.

### Can I bypass the authorization gate using the -Force flag?

No. The `-Force` and `--force` flags are explicitly designed **not** to bypass the authorization gate. As documented in [`RULES.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/RULES.md) and implemented in the `case-guard` scripts, these flags are ignored during authorization checks. The gate requires the explicit `auth.status=granted` value in [`scope.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/scope.md) regardless of force flags provided at the command line.

### Where is the network_profile requirement defined?

The `network_profile` requirement appears in multiple authoritative locations. [`RULES.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/RULES.md) mandates its presence alongside `auth.status`, while [`skills/ops/scope-contract.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/ops/scope-contract.md) formalizes it as a required checklist item. The `case-guard` scripts validate this field at runtime, ensuring that every operation includes documented network context or authorized offline sample references.

### Which files should I review to understand the complete authorization flow?

Start with [`RULES.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/RULES.md) for the core policy, then examine `skills/scripts/case-init.ps1` (or `.sh`) for initialization logic. Review [`skills/ops/scope-contract.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/ops/scope-contract.md) for validation requirements, and inspect `skills/scripts/case-guard.ps1` (or `.sh`) for runtime enforcement details. The routing documentation in [`AGENTS.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/AGENTS.md) explains how these components integrate into the execution workflow.
