How the Authorization Gate in reverse-skill Enforces Access Control Before Task Execution

The Authorization Gate in reverse-skill is a hard-coded, mandatory checkpoint defined in AGENTS.md that prevents any skill execution until the user initializes a case scope, sets auth.status=granted, and declares valid targets, with explicit rejection of force-bypass attempts.

The zhaoxuya520/reverse-skill repository provides a structured framework for reverse-engineering and penetration-testing operations. At its core sits the Authorization Gate, a non-configurable security mechanism that blocks accidental or unauthorized execution of potentially destructive tasks. This gate enforces strict pre-conditions—encompassing case scoping, authentication flags, and target validation—before dispatching any skill routine.

How the Authorization Gate Works

The Authorization Gate operates as a hard-wired enforcement layer within the routing scripts. According to AGENTS.md, the gate implements five mandatory controls that cannot be overridden at runtime, ensuring every operation respects organizational security policies.

Case Initialization and Scope Definition

Every target operation must begin with case initialization, which creates a project-specific scope file at work/<case>/scope.md. This file records the intended task, target environment, and operational constraints. The initialization is performed via platform-specific scripts:

• Linux/macOS/Kali: bash skills/scripts/case-init.sh --hint "<task>"
• Windows: powershell -File skills/scripts/case-init.ps1 -Hint "<task>"

These scripts automatically generate the scope document, establishing the legal and technical boundaries for subsequent actions.

Offline-Sample Guard Requirements

When operating with the offline-sample preset, the gate requires two simultaneous conditions. First, the global flag auth.status=granted must be present in the scope document. Second, the target sample must be explicitly declared. If either condition is absent, the framework aborts execution immediately, preventing accidental operations on unspecified targets.

Network-Profile Guard for Live Environments

For real-world network interactions, the gate enforces auth.status=granted and mandates a valid network_profile configuration. Unlike offline operations, live targeting requires explicit network authorization credentials. The routing scripts validate this profile before dispatching any network-touching skills, blocking execution if the authentication context is incomplete.

Force-Bypass Prohibition

The Authorization Gate is deliberately resistant to override attempts. Commands such as case-guard --force or -Force flags are explicitly rejected by the enforcement logic. This design choice eliminates the risk of accidental circumvention, ensuring that no script or tool can skip the mandatory security checks through command-line arguments.

Evidence Tracking and Audit Trails

After passing the gate, the system records operational metadata to skills/ops/evidence-finding-path.md and skills/ops/role-map.md. These files provide immutable audit trails, documenting who authorized the action and under what scope. This evidence tracking reinforces compliance requirements and enables post-operation reviews.

Implementing the Authorization Workflow

Practical usage requires executing the initialization scripts followed by verification of the authentication flag. The routing scripts will reject execution if auth.status=granted is missing or improperly configured.

Initializing a Case on Linux/macOS/Kali:

# Create the case scope and set task context

bash skills/scripts/case-init.sh --hint "Enumerate AD trust relationships"

# Verify the authorization status was written

grep "auth.status" work/AD-Trust/scope.md

# Attempt execution—blocked if gate conditions fail

bash skills/scripts/master-route.sh --hint "Enumerate AD trust relationships"

Initializing a Case on Windows:

# Create the case scope via PowerShell

powershell -File skills/scripts/case-init.ps1 -Hint "Dump LSASS memory"

# Confirm authorization flag exists

Select-String -Path work\LSASS-Dump\scope.md -Pattern "auth.status"

# Execute skill—abort if gate checks fail

powershell -NoProfile -ExecutionPolicy Bypass -File skills/scripts/master-route.ps1 -Hint "Dump LSASS memory"

If authorization requirements are not met, the scripts output a fatal error:

[!] Authorization gate not passed – set auth.status=granted and specify a valid sample or network_profile.

Key Source Files Controlling the Gate

The Authorization Gate is implemented across several critical files within the repository:

• AGENTS.md: Defines the human-readable policy specification, including the "授权门禁（硬性）" (Authorization Gate - Hard) requirements and routing logic.
• skills/scripts/case-init.sh and skills/scripts/case-init.ps1: Implement case initialization, creating the work/<case>/scope.md files that store auth.status and task parameters.
• skills/scripts/master-route.sh and skills/scripts/master-route.ps1: Entry points for skill execution that enforce the gate checks before dispatching tasks.
• skills/ops/evidence-finding-path.md: Documents the evidence collection workflow activated after successful authorization.
• skills/ops/role-map.md: Maps operational roles to permissions, supporting the audit trail requirements of the gate.

Summary

• The Authorization Gate is a mandatory, non-configurable checkpoint defined in AGENTS.md that prevents unauthorized skill execution.
• Case initialization via case-init.sh or case-init.ps1 is required to create work/<case>/scope.md before any operations.
• Execution requires auth.status=granted paired with either an explicit offline sample declaration or a valid network profile.
• Force-bypass attempts using --force or -Force flags are explicitly rejected by the gate logic.
• Comprehensive audit trails are maintained through skills/ops/evidence-finding-path.md and role-map.md.

Frequently Asked Questions

What triggers the Authorization Gate in reverse-skill?

The gate triggers automatically whenever skills/scripts/master-route.sh or master-route.ps1 is invoked to execute a skill. The script inspects the corresponding work/<case>/scope.md file for auth.status=granted and valid target declarations before allowing the operation to proceed.

Can I bypass the Authorization Gate with force flags?

No. The gate explicitly rejects case-guard --force and -Force parameters. This hard-coded prohibition prevents accidental circumvention of security checks, ensuring that authorization requirements cannot be overridden via command-line arguments.

Where is the authorization status stored?

The authorization status is stored in the case-specific scope document at work/<case>/scope.md, created during case initialization. The case-init scripts write auth.status=granted to this file only when proper validation criteria are met.

How does the gate differentiate between offline samples and live networks?

For offline samples, the gate requires auth.status=granted plus an explicit sample declaration. For live networks, it requires auth.status=granted plus a valid network_profile configuration. The routing scripts distinguish these contexts based on the parameters stored in the scope document and fail closed if the specific requirements for the chosen mode are not satisfied.
