**Reverse-Skill provides built-in monitoring utilities across five architectural layers—Tool-Index detection, MCP HTTP hooks, zero-flag GDB callbacks, Wi-Fi monitor mode, and application-specific clipboard watchers—to capture telemetry from every security analysis workflow.**

Reverse-Skill functions as a **skill router** that orchestrates binary reverse-engineering, mobile inspection, penetration-testing, CTF challenges, and wireless assessments. Understanding how to monitor Reverse-Skill applications ensures you maintain visibility into tool execution, simplify debugging, and preserve evidence for forensic reporting. This guide walks through the monitoring architecture, activation workflows, and code-level integration points based on the `zhaoxuya520/reverse-skill` source code.

## Understanding Reverse-Skill's Monitoring Architecture

Monitoring in Reverse-Skill operates across five distinct layers, each targeting different telemetry sources. The table below maps each layer to its function and source location in the repository:

| Layer | Purpose | Source Location |
|-------|---------|-----------------|
| **Tool-Index** | Detects installed monitoring binaries (`ws_monitor`, `mojo_monitor`, `syscall_start_monitor`) | [`skills/tool-index.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/tool-index.md) (auto-generated) |
| **MCP Hooks** | Exposes monitoring functions as HTTP endpoints (`/monitor`, `/get_connections`) | `skills/pentest-tools/src-hunter/references/tools/mcp‑jshook.md` |
| **Zero-Flag Monitoring** | Receives zero-flag events during GDB decompilation to infer password bytes | [`skills/reverse-engineering/tools-advanced.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/reverse-engineering/tools-advanced.md) |
| **Wi-Fi Monitor Mode** | Puts wireless adapters into monitor mode for packet capture | [`skills/wifi-wireless/SKILL.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/wifi-wireless/SKILL.md) |
| **Application-Specific Monitors** | Mobile clipboard/pasteboard monitoring for iOS/Android | [`skills/mobile-reverse/references/frida-objection-deep.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/mobile-reverse/references/frida-objection-deep.md) |

## Step 1: Refresh the Tool Index to Discover Available Monitors

Before launching any monitor, you must generate a current inventory of installed binaries. Reverse-Skill provides platform-specific scripts in `skills/scripts/` that populate [`skills/tool-index.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/tool-index.md).

### Platform-Specific Commands

```bash

# Windows PowerShell

powershell -File skills/scripts/refresh-tool-index.ps1

# Linux or macOS

bash skills/scripts/refresh-tool-index.sh

# Kali Linux (specialized environment)

bash kali/scripts/refresh-tool-index.sh

```

The generated [`skills/tool-index.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/tool-index.md) lists all detected monitoring utilities. Inspect this file to confirm which binaries are available on your host before proceeding.

---

## Step 2: Select the Appropriate Monitor Type

Reverse-Skill's MCP layer exposes three primary monitor hooks for different interception targets. Choose based on your analysis objective:

- **`ws_monitor`** → WebSocket traffic interception
- **`mojo_monitor`** → Mojo-IPC message capture (Chromium-based applications)
- **`syscall_start_monitor`** → System-call activity logging

These hooks are defined in `skills/pentest-tools/src-hunter/references/tools/mcp‑jshook.md` and exposed through the MCP HTTP API.

---

## Step 3: Activate Monitors via MCP API

### WebSocket Monitor Example

Start the monitor as a background process, then retrieve captured frames through the REST endpoint:

```bash

# Start WebSocket monitor (background execution)

mcp__jshook__ws_monitor &

# After target application runs, pull captured connections

curl -s http://localhost:8080/api/ws_get_connections | jq .

# Terminate monitor when complete

pkill -f mcp__jshook__ws_monitor

```

The `mcp__jshook__ws_monitor` binary exposes frames at `/api/ws_get_connections` as documented in the MCP hook reference.

---

## Step 4: Integrate Zero-Flag Monitoring in Decompilation Workflows

For binary reverse-engineering, Reverse-Skill supports **callback-based monitoring** during GDB-driven decompilation. The `monitor` parameter of `decompileFunction` receives structured events.

### Python Integration Example

```python
def monitor(event):
    """Log zero-flag events to infer successful byte comparisons."""
    if event.type == 'zf' and event.value:
        print(f"[ZFLAG] Zero-flag set at address {event.addr:#x}")

# Pass monitor callback to decompiler

result = decomp.decompileFunction(target_func, max_steps=30, monitor=monitor)

```

This pattern appears in [`skills/reverse-engineering/tools-advanced.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/reverse-engineering/tools-advanced.md), where the monitor infers password bytes by observing when the zero flag is set during conditional jumps.

---

## Step 5: Enable Wi-Fi Monitor Mode for Wireless Assessment

Wireless security workflows require adapter-level monitoring. Reverse-Skill documents this in [`skills/wifi-wireless/SKILL.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/wifi-wireless/SKILL.md).

### Linux/macOS Monitor Mode Activation

```bash

# Kill interfering processes

airmon-ng check kill

# Enable monitor mode on wlan0

airmon-ng start wlan0

# Verify mode transition

iwconfig wlan0

```

This places the interface in **RFMON (monitor) mode**, enabling raw 802.11 frame capture without association to an access point.

---

## Step 6: Archive Evidence and Shutdown

Reverse-Skill's evidence chain contracts in `skills/ops/` automate case directory structure. After monitoring completes:

1. Copy logs from monitor processes to `work/<case>/evidence/`
2. Terminate background monitors with `pkill -f <monitor_name>`
3. Verify integrity using the timeline generation scripts in `skills/ops/`

The `case-init.ps1` script automatically creates `work/<case>/evidence/` directories during case setup.

---

## Summary

- **Refresh the tool index** before any monitoring session to confirm binary availability
- **Use MCP hooks** (`ws_monitor`, `mojo_monitor`, `syscall_start_monitor`) for network and IPC interception
- **Pass monitor callbacks** to `decompileFunction` for zero-flag event logging during reverse-engineering
- **Enable monitor mode** via `airmon-ng` for wireless packet capture
- **Archive all telemetry** to `work/<case>/evidence/` per `skills/ops/` contracts

## Frequently Asked Questions

### What is the Tool-Index in Reverse-Skill?

The **Tool-Index** is an auto-generated inventory at [`skills/tool-index.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/tool-index.md) that catalogs every monitoring binary installed on your host system. Run [`refresh-tool-index.sh`](https://github.com/zhaoxuya520/reverse-skill/blob/main/refresh-tool-index.sh) (Linux/macOS/Kali) or `refresh-tool-index.ps1` (Windows) to update it.

### How do I capture WebSocket traffic with Reverse-Skill?

Start `mcp__jshook__ws_monitor` as a background process, then query `http://localhost:8080/api/ws_get_connections` to retrieve captured frames. Stop the process with `pkill` when finished.

### Can I monitor system calls instead of network traffic?

Yes. Use `syscall_start_monitor` (exposed as `mcp__jshook__syscall_start_monitor`) through the same MCP hook infrastructure documented in `skills/pentest-tools/src-hunter/references/tools/mcp‑jshook.md`.

### Where does Reverse-Skill store monitoring evidence?

Evidence lands in `work/<case>/evidence/` directories created by `case-init.ps1`, following the chain-of-custody contracts defined in `skills/ops/`.
