+## [2.2.0] - 2025-11-03
+
+### Added
+- **Auto PATH Configuration**: Installer automatically detects shell (bash/zsh/fish) and adds `~/.local/bin` to PATH
+- **Terminal Color Support**: ANSI color codes with TTY detection for enhanced visual feedback
+- **NO_COLOR Support**: Respects NO_COLOR environment variable for accessibility
+- **Enhanced Error Messages**: Box-drawing characters for critical errors (╔═╗ style)
+- Multi-shell support with shell-specific syntax (bash/zsh: `export`, fish: `set -gx`)
+- Idempotent PATH configuration (checks for existing entries before adding)
+- Shell profile detection logic with automatic configuration
+- Reload instructions after installation (source profile or new terminal)
+- Manual PATH fallback instructions if auto-config fails
+- **Install Location Display**: --version output shows installation path
+
+### Changed
+- **Unified Install Location**: All Unix systems now use `~/.local/bin` (consistent across macOS/Linux)
+- **No Sudo Required**: User-writable location eliminates permission issues
+- **All Emojis Removed**: Replaced with ASCII symbols for universal compatibility
+  - [!] for warnings
+  - [OK] for success
+  - [X] for errors
+  - [i] for information
+- **PATH Warnings Enhanced**: Step-by-step instructions for shell configuration
+- **GLM API Key Notices Improved**: Actionable guidance with URLs and examples
+- **Error Message Format**: Consistent boxed formatting across all scripts
+- **Success/Warning/Info Messages**: Unified styling with color support
+- Enhanced PATH configuration workflow with clear user instructions
+- Simplified installation process (one location for all platforms)
+
+### Fixed
+- **Shell Injection Vulnerability**: Critical security fix in shell detection (CVE-level)
+- Error handling for profile directory creation
+- Profile file creation errors now properly handled
+- SHELL environment variable edge cases
+
+### Technical Details
+- **Files Modified**:
+  - installers/install.sh: Auto PATH config functions, shell detection, security fixes
+  - installers/install.ps1: Color function equivalents
+  - installers/uninstall.sh: Color functions, simplified cleanup
+  - installers/uninstall.ps1: Color function equivalents
+  - ccs: Color functions, enhanced error messages, install location display
+  - ccs.ps1: Enhanced error messages with PowerShell colors
+- **Lines Added**: ~200+ (new auto PATH logic)
+- **Lines Removed**: ~50 (platform-specific code)
+- **Test Coverage**: 100% pass rate (syntax, idempotent, shell detection, security)
+- **Security Review**: Approved after fixes (shell injection vulnerability patched)
+- **Cross-Platform Parity**: Maintained across macOS, Linux, Windows
+
+### Migration Notes
+
+#### For All Unix Users (macOS & Linux)
+Installation location: `~/.local/bin/ccs`
+
+**What Happens Automatically:**
+1. Installer detects your shell (bash/zsh/fish)
+2. Checks if ~/.local/bin in PATH
+3. If not, adds to shell profile with clear comment
+4. Shows reload instructions
+
+**Manual PATH Config (if auto-config fails):**
+```bash
+# For bash/zsh
+echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc  # or ~/.zshrc
+
+# For fish
+echo 'set -gx PATH $HOME/.local/bin $PATH' >> ~/.config/fish/config.fish
+
+# Reload
+source ~/.bashrc  # or ~/.zshrc or restart terminal
+```
+
+#### For Windows Users
+No changes. Installation remains at `~/.ccs/ccs.ps1` with automatic PATH configuration.

 ## Key Constraints
 
-1. **NO EMOJIS in terminal output** - Users of this `ccs` project may lack encoders by default. Try to find alternatives to illustrate signals
-2. **Idempotent installations** - Running install scripts multiple times must be safe
-3. **Non-invasive** - Never modify `~/.claude/settings.json`
-4. **Cross-platform parity** - Identical behavior on Unix/Linux/macOS/Windows
-5. **Edge case handling** - Handle all scenarios gracefully (see tests/edge-cases.sh)
+1. **NO EMOJIS in terminal output** - Use ASCII symbols ([OK], [!], [X], [i]) for compatibility
+2. **TTY-aware color output** - Colors only when output to terminal, respects NO_COLOR env var
+3. **Unified install location** (v2.2.0+):
+   - All Unix: `~/.local/bin` (auto PATH config, no sudo)
+   - Windows: `%USERPROFILE%\.ccs`

 ### Process
 
-1. **Create directories**: `~/.ccs/`, `~/.local/bin/`
-2. **Install executables**:
+1. **Platform Detection**: Windows vs Unix
+2. **Create directories**: `~/.ccs/`, `~/.local/bin`
+3. **Clean old installs**: Remove old `/usr/local/bin` installations (if CCS symlinks)
+4. **Install executables**:
    - Git mode: Symlink from repo
    - Standalone: Download from GitHub
-3. **Install .claude folder**: Commands and skills
-4. **Create config**: `config.json` if missing
-5. **Create GLM profile**: `glm.settings.json` if missing
-6. **Backup**: Single `config.json.backup` (overwrites)
-7. **Validate**: Check JSON syntax
+5. **Install .claude folder**: Commands and skills
+6. **Create config**: `config.json` if missing
+7. **Create GLM profile**: `glm.settings.json` if missing
+8. **Backup**: Single `config.json.backup` (overwrites)
+9. **Validate**: Check JSON syntax
+10. **Configure PATH**: Auto-detect shell, add to profile
+11. **Display instructions**: Shell reload, GLM API key (if needed)
+
+### Unified Install Location (v2.2.0+)
+
+**All Unix Systems**: `~/.local/bin/ccs`
+- User-writable, no sudo required
+- Auto PATH configuration for bash, zsh, fish
+- Idempotent setup (safe to run multiple times)
+
+**Windows**: `%USERPROFILE%\.ccs\ccs.ps1`
+- Auto-added to user PATH
+
+### Shell Profile Management
+
+**Auto-detection** (`detect_shell_profile()`):
+- Extracts shell from `$SHELL` variable
+- Returns appropriate profile file:
+  - bash: `~/.bashrc` (Linux) or `~/.bash_profile` (macOS)
+  - zsh: `~/.zshrc`
+  - fish: `~/.config/fish/config.fish`
+- Validates shell name (alphanumeric only)
+- Defaults to `~/.bashrc` if unknown
+
+**PATH checking** (`check_path_configured()`):
+- Tests if `~/.local/bin` in current `$PATH`
+- Returns true if already configured
+
+**PATH addition** (`add_to_path()`):
+- Creates profile file if missing
+- Checks for existing CCS marker comment
+- Adds shell-specific PATH export:
+  - bash/zsh: `export PATH="$HOME/.local/bin:$PATH"`
+  - fish: `set -gx PATH $HOME/.local/bin $PATH`
+- Idempotent: skips if already added
+
+**Configuration workflow** (`configure_shell_path()`):
+- Checks if PATH already configured
+- Detects shell profile
+- Adds PATH entry
+- Shows reload instructions
+- Fallback to manual instructions if fails

+## Terminal Output Standards
+
+### Color Functions
+
+**TTY Detection**: Colors only shown when output is to terminal (not piped/redirected)
+```bash
+if [[ -t 2 ]] && [[ -z "${NO_COLOR:-}" ]]; then
+  # Enable colors
+else
+  # Disable colors
+fi
+```
+
+**NO_COLOR Support**: Respects `NO_COLOR` environment variable

+export NO_COLOR=1  # Disables all color output
+```
+
+### Message Types
+
+**Error Messages** (red, boxed):
+```
+╔═════════════════════════════════════════════╗
+║  ERROR                                      ║
+╚═════════════════════════════════════════════╝

+[!] WARNING
+```
+
+**Success Messages** (green):
+```
+[OK] Success message
+```
+
+**Info Messages** (plain):
+```
+[i] Information
+```
+
+### ASCII Symbols (No Emojis)
+
+All output uses ASCII symbols for compatibility:
+- `[OK]` - Success
+- `[!]` - Warning
+- `[X]` - Error/Failure
+- `[i]` - Information
+
 ## Key Points
 
-1. **Installation**: Creates 2 profiles (glm + default), validates JSON
+1. **Installation**: Unified location (`~/.local/bin`), auto PATH config, validates JSON
 2. **Runtime**: Simple delegation to Claude CLI via `--settings` flag
-3. **Cross-platform**: Identical behavior on Unix/Linux/macOS/Windows
+3. **Cross-platform**: Unified Unix location, identical behavior
 4. **Non-invasive**: Never touches `~/.claude/settings.json`
 5. **Validation**: JSON syntax checking prevents errors
 6. **Backup**: Single file, overwrites each install
+7. **Terminal Output**: TTY detection, NO_COLOR support, ASCII symbols only
+8. **Shell Support**: Auto-detects bash, zsh, fish

+## Auto PATH Configuration
+
+The installer automatically configures your shell PATH:
+
+**Supported Shells**:
+- bash (`.bashrc` or `.bash_profile`)
+- zsh (`.zshrc`)
+- fish (`.config/fish/config.fish`)
+
+**How It Works**:
+1. Detects your current shell from `$SHELL` environment variable
+2. Checks if `~/.local/bin` already in PATH
+3. If not, adds appropriate export to shell profile
+4. Shows reload instructions
+
+**Idempotent**:
+- Safe to run multiple times
+- Checks for existing CCS PATH entry before adding
+- Won't create duplicate entries
+
+**Manual PATH Setup** (if auto-config fails):
+
+Bash/Zsh:
+```bash
+echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc  # or ~/.zshrc
+source ~/.bashrc  # or source ~/.zshrc

-## Environment Issues
+## PATH Configuration Issues
 
-### PATH not set
+### Auto PATH Configuration
 
-```
-⚠️  Warning: ~/.local/bin is not in PATH
-```
+v2.2.0+ automatically configures shell PATH. If you see reload instructions after install, follow them:
 
-**Fix**: Add to `~/.bashrc` or `~/.zshrc`:
+**For bash**:
 ```bash
-export PATH="$HOME/.local/bin:$PATH"
+source ~/.bashrc
 ```
-Then `source ~/.bashrc` or restart shell.
+
+**For zsh**:
+```bash
+source ~/.zshrc
+```
+
+**For fish**:
+```fish
+source ~/.config/fish/config.fish
+```
+
+**Or open new terminal window** (PATH auto-loaded).
+
+### PATH Not Configured
+
+If `ccs` command not found after install and reload:
+
+**Verify PATH entry exists**:
+```bash
+# For bash/zsh
+grep "\.local/bin" ~/.bashrc ~/.zshrc
+
+# For fish
+grep "\.local/bin" ~/.config/fish/config.fish
+```
+
+**Manual fix** (if auto-config failed):
+
+Bash:
+```bash
+echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
+source ~/.bashrc
+```
+
+Zsh:
+```bash
+echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc
+source ~/.zshrc
+```
+
+Fish:
+```fish
+echo 'set -gx PATH $HOME/.local/bin $PATH' >> ~/.config/fish/config.fish
+source ~/.config/fish/config.fish
+```
+
+### Wrong Shell Profile
+
+If auto-config added to wrong file:
+
+**Find active profile**:
+```bash
+echo $SHELL  # Shows current shell
+```
+
+**Common scenarios**:
+- macOS bash uses `~/.bash_profile` (not `~/.bashrc`)
+- Custom shells need manual config
+- Tmux/screen may use different shell
+
+**Solution**: Manually add PATH to correct profile file.
+
+### Shell Not Detected
+
+If installer couldn't detect shell:
+
+**Symptoms**:
+- No PATH warning shown
+- `ccs` command not found after install
+
+**Solution**: Manual PATH setup (see above).
