Haiou Claude Personality Mod

Skill by ara.so — Claude Code Skills collection.

Overview

Haiou 2.0 (Seagull 2.0) is a custom personality configuration package for Claude Code that replaces the default assistant persona with "Seagull" — a direct, technically-focused Chinese security researcher character. The mod includes:

• 1700+ few-shot dialogue examples for stable personality
• 200+ security/gaming terminology mappings (pentesting, reverse engineering, game dev)
• Custom system prompts that reduce verbose disclaimers
• Cross-platform deployment scripts (Windows/macOS/Linux)
• Automatic backup of original configuration
• Signature greeting: "海鸥在线，你要整点薯条吗？" (Seagull online, want some fries?)

Configuration Files

CLAUDE.md

The main personality configuration file located at ~/.claude/CLAUDE.md (Linux/macOS) or %APPDATA%\Local\Claude-3p\CLAUDE.md (Windows). Contains:

• Character background and traits
• 1700+ few-shot examples
• Response style guidelines
• Technical terminology mappings

system-prompt.md

System-level prompt overrides at ~/.claude/system-prompt.md that:

• Reduce "As an AI" disclaimers
• Enable direct technical responses
• Configure Chinese language preference
• Set security research context

Verification

After installation, restart Claude Code and test:

User: 在吗
Seagull: 海鸥在线，你要整点薯条吗？

Key Deployment Script Features

Windows (deploy.ps1)

# Check for Claude Code installation
$claudePaths = @(
    "$env:USERPROFILE\.claude",
    "$env:LOCALAPPDATA\Claude-3p",
    "$env:APPDATA\Claude"
)

# Backup existing configuration
$backupDir = "$env:USERPROFILE\.claude\backups\seagull-$(Get-Date -Format 'yyyyMMdd-HHmmss')"
New-Item -ItemType Directory -Force -Path $backupDir

# Deploy configuration files
Copy-Item -Path "claude-config-bundle\*" -Destination "$HOME\.claude\" -Force

Linux/macOS (linux-install.sh)

#!/bin/bash

# Detect Claude Code installation
CLAUDE_DIR="$HOME/.claude"
BACKUP_DIR="$CLAUDE_DIR/backups/seagull-$(date +%Y%m%d-%H%M%S)"

# Create backup
if [ -d "$CLAUDE_DIR" ]; then
    mkdir -p "$BACKUP_DIR"
    cp -r "$CLAUDE_DIR"/*.md "$BACKUP_DIR/" 2>/dev/null || true
fi

# Deploy configuration
cp claude-config-bundle/*.md "$CLAUDE_DIR/"
chmod 644 "$CLAUDE_DIR"/*.md

Uninstallation

Windows

# Double-click uninstaller
卸载.bat

# Or run PowerShell script
powershell -ExecutionPolicy Bypass -File seagull-files/uninstall.ps1

macOS

./mac-uninstall.sh
# Or double-click: 卸载.command

Linux

cd seagull-files
./linux-uninstall.sh

Uninstallation restores the most recent backup from ~/.claude/backups/.

Manual Configuration Restoration

If automatic uninstall fails:

# Linux/macOS
cd ~/.claude/backups
ls -lt  # Find most recent backup
cp seagull-YYYYMMDD-HHMMSS/* ~/.claude/

# Windows PowerShell
cd $env:USERPROFILE\.claude\backups
# Copy files from latest backup folder to parent directory

Troubleshooting

Configuration Not Taking Effect

Problem: Claude Code shows no personality change after installation.

Solution:

# 1. Verify files were deployed
ls -la ~/.claude/  # Should show CLAUDE.md and system-prompt.md

# 2. Check file permissions
chmod 644 ~/.claude/*.md

# 3. Fully restart Claude Code (quit application, not just close window)
# Windows: Task Manager → End Process
# macOS: Cmd+Q to fully quit
# Linux: killall claude-code

macOS Gatekeeper Warnings

Problem: "Cannot verify developer" when running .command files.

Solution:

# Remove quarantine flag
xattr -d com.apple.quarantine 启动.command
xattr -d com.apple.quarantine 卸载.command

# Or right-click → Open → confirm dialog

Multiple Claude Installations

Problem: Configuration applied but desktop app doesn't reflect changes.

Solution:

# Deploy manually to all possible locations
for dir in ~/.claude ~/.config/claude ~/Library/Application\ Support/Claude; do
    if [ -d "$dir" ]; then
        cp seagull-files/claude-config-bundle/*.md "$dir/"
    fi
done

Windows Execution Policy

Problem: deploy.ps1 blocked by execution policy.

Solution:

# Temporary bypass (current session)
Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass

# Or run with -ExecutionPolicy flag
powershell -ExecutionPolicy Bypass -File seagull-files/deploy.ps1

Character Encoding Issues

Problem: Chinese characters display incorrectly.

Solution:

# Ensure UTF-8 encoding
file -bi ~/.claude/CLAUDE.md  # Should show charset=utf-8

# Re-deploy with correct encoding
iconv -f GBK -t UTF-8 CLAUDE.md > CLAUDE_utf8.md
mv CLAUDE_utf8.md ~/.claude/CLAUDE.md

Advanced Configuration

Custom Personality Tweaks

Edit ~/.claude/CLAUDE.md to adjust:

# Modify response style
响应风格：
- 直接、简洁  # Change verbosity
- 技术优先  # Adjust technical depth
- 中文为主  # Language preference

# Add custom terminology
术语映射：
- my_custom_term -> 自定义术语

Environment-Specific Deployment

# Deploy to specific Claude installation
CLAUDE_DIR="/opt/claude" ./linux-install.sh

# Preserve custom modifications during deployment
cp ~/.claude/custom-config.md /tmp/
./mac-install.sh
cp /tmp/custom-config.md ~/.claude/

Validation Script

#!/bin/bash
# validate-install.sh
CLAUDE_DIR="$HOME/.claude"

echo "Checking installation..."
[ -f "$CLAUDE_DIR/CLAUDE.md" ] && echo "✓ CLAUDE.md present" || echo "✗ CLAUDE.md missing"
[ -f "$CLAUDE_DIR/system-prompt.md" ] && echo "✓ system-prompt.md present" || echo "✗ system-prompt.md missing"

# Check backup exists
BACKUP_COUNT=$(ls -1 "$CLAUDE_DIR/backups" 2>/dev/null | wc -l)
echo "Backups available: $BACKUP_COUNT"

Compatibility

Platform	Status	Notes
Windows 10/11	✅	Requires PowerShell 5.1+
macOS 12+	✅	Intel & Apple Silicon
Ubuntu/Debian	✅	Bash 4.0+
Arch Linux	✅	Standard install
Chinese paths	✅	Full UTF-8 support
Spaces in paths	✅	Properly quoted

Security Considerations

• Backup retention: Old backups accumulate in ~/.claude/backups/ — clean periodically
• File permissions: Configuration files are user-readable only (644)
• No network calls: All scripts operate locally
• Reversible: Uninstall restores original configuration completely
