# Changelog

Format: [Keep a Changelog](https://keepachangelog.com/)

## [5.0.0] - 2025-11-28

### Added
- **CLIProxy OAuth Profiles**: Three new zero-config profiles powered by CLIProxyAPI
  - `ccs gemini` - Google Gemini via OAuth (zero config)
  - `ccs codex` - OpenAI Codex via OAuth (zero config)
  - `ccs agy` - Antigravity (AGY) via OAuth (zero config)

  - Headless mode fallback (`ccs gemini --auth --headless`)
  - Token storage in `~/.ccs/cliproxy-auth/<provider>/`
  - 2-minute OAuth timeout protection

- **CLIProxy Diagnostics** in `ccs doctor`:
  - Binary installation status + version
  - Config file validation
  - OAuth status per provider (gemini/codex/agy)
  - Port 8317 availability check

- **Enhanced Error Messages** (`src/utils/error-manager.ts`):
  - OAuth timeout troubleshooting

  3. Account-based profiles (work, personal)
  4. Default Claude CLI
- **Help Text**: Updated with new OAuth profiles (alphabetically sorted)
- **Profile Detector**: Added `cliproxy` profile type

### Technical Details
- **Binary Version**: CLIProxyAPI v6.5.27
- **Default Port**: 8317 (TCP polling for readiness, no PROXY_READY signal)

  - Gemini: gemini-2.0-flash (opus: thinking-exp, haiku: flash-lite)
  - Codex: gpt-4o (opus: o1, haiku: gpt-4o-mini)
  - Antigravity: agy (sonnet: agy-pro, haiku: agy-turbo)
- **Storage**:
  - Binary: `~/.ccs/bin/cliproxyapi`
  - Tokens: `~/.ccs/cliproxy-auth/<provider>/`
  - Config: `~/.ccs/cliproxy.config.yaml`

### Migration
- **No breaking changes**: All existing profiles (glm, glmt, kimi, accounts) work unchanged
- **Zero configuration**: OAuth profiles work out-of-box after browser login
- **Backward compatible**: v4.x commands and workflows unchanged

---

## [4.5.0] - 2025-11-27 (Phase 02 Complete)

### Changed
- **Modular Command Architecture**: Complete refactoring of command handling system
  - Main entry point (src/ccs.ts) reduced from 1,071 to 593 lines (**44.6% reduction**)
  - 6 command handlers extracted to dedicated modules in `src/commands/`
  - Enhanced maintainability through single responsibility principle
  - Command handlers can now be developed and tested independently

### Added
- **Modular Command Handlers** (`src/commands/`):
  - `version-command.ts` (3.0KB) - Version display functionality
  - `help-command.ts` (4.9KB) - Comprehensive help system
  - `install-command.ts` (957B) - Installation/uninstallation workflows
  - `doctor-command.ts` (415B) - System diagnostics
  - `sync-command.ts` (1.0KB) - Configuration synchronization
  - `shell-completion-command.ts` (2.1KB) - Shell completion management

- **New Utility Modules** (`src/utils/`):
  - `shell-executor.ts` (1.5KB) - Cross-platform shell command execution
  - `package-manager-detector.ts` (3.8KB) - Package manager detection (npm, yarn, pnpm, bun)

- **TypeScript Type System**:
  - `src/types/` directory with comprehensive type definitions
  - Standardized `CommandHandler` interface for all commands
  - 100% TypeScript coverage across all new modules

### Improved
- **Maintainability**: Each command now has focused, dedicated module
- **Testing Independence**: Command handlers can be unit tested in isolation
- **Development Workflow**: Multiple developers can work on different commands simultaneously
- **Code Navigation**: Developers can quickly locate specific command logic
- **Future Extension**: New commands can be added without modifying main orchestrator

### Technical Details
- **Zero Breaking Changes**: All existing functionality preserved
- **Performance**: No degradation, minor improvement due to smaller main file
- **Quality Gates**: All Phase 01 ESLint strictness rules maintained
- **Type Safety**: Comprehensive TypeScript coverage with zero `any` types
- **Interface Consistency**: All commands follow standardized `CommandHandler` interface

## [4.4.0] - 2025-11-23

### Changed
- **BREAKING**: settings.json now shared across profiles via symlinks
  - Each profile previously had isolated settings.json
  - Now all profiles share ~/.claude/settings.json
  - Migration automatic on install (uses ~/.claude/settings.json)
  - Backups created: `<instance>/settings.json.pre-shared-migration`
  - Rollback: restore backup manually if needed

### Added
- Doctor validates settings.json symlink integrity
- Sync repairs broken settings.json symlinks
- Migration from isolated to shared settings (automatic)

### Fixed
- Consistent shared data architecture across all .claude/ items

## [4.3.10] - 2025-11-23

### Fixed
- **Update Cache Issue**: Fixed `ccs update` serving cached package versions instead of fresh downloads
- Package manager cache is now automatically cleared before updating
- Update now ensures users always receive the latest version from registry

### Technical Details
- **Node.js (bin/ccs.js)**: Added cache clearing for npm, yarn, pnpm before update
  - npm: `npm cache clean --force`
  - yarn: `yarn cache clean`
  - pnpm: `pnpm store prune`
  - bun: No explicit cache clearing needed
- **Bash (lib/ccs)**: Added `npm cache clean --force` before npm update
- **PowerShell (lib/ccs.ps1)**: Added `npm cache clean --force` before npm update
- **Non-blocking**: Update continues even if cache clearing fails (with warning)
- **Manual fallback commands**: Updated to include cache clearing step

### Impact
- Users no longer need to manually run `npm cache clean --force` before `ccs update`
- Resolves issue where update reported success but installed cached/outdated version
- Ensures fresh package downloads from npm registry on every update

## [4.3.8] - 2025-11-23

### Fixed
- **ora v9 Compatibility**: Fixed "ora is not a function" errors in `ccs doctor` and installer utilities
- Properly handle ora v9+ ES module format when using CommonJS `require()`
- All spinner-based operations now work correctly with ora v9.0.0

### Technical Details
- ora v9+ is an ES module, requiring `.default` property access in CommonJS
- Updated import: `const oraModule = require('ora'); ora = oraModule.default || oraModule`
- Fallback spinner implementation ensures graceful degradation when ora is unavailable
- Affects: `bin/management/doctor.js`, `bin/utils/claude-dir-installer.js`, `bin/utils/claude-symlink-manager.js`
- Impact: `ccs doctor` command and postinstall scripts now work correctly with latest ora version

## [4.3.7] - 2025-11-23

### Fixed
- **Postinstall Script**: Fixed missing `~/.ccs/.claude/` directory during `npm install`
- Made `ora` dependency optional in `ClaudeDirInstaller` and `ClaudeSymlinkManager`
- Postinstall script now gracefully handles missing `ora` module during installation
- Ensures `.claude/` directory and symlinks are properly created even when `ora` is unavailable

### Technical Details
- Root cause: `ora` module not available during `npm install` postinstall execution
- Solution: Optional require with fallback to `console.log` when `ora` is unavailable
- Affects: `bin/utils/claude-dir-installer.js`, `bin/utils/claude-symlink-manager.js`
- Impact: All npm installations now properly create `~/.ccs/.claude/` and CCS symlinks

## [4.3.6] - 2025-11-23

### Added
- **Plugin Support**: Claude Code plugins now shared across all CCS profiles via `~/.ccs/shared/plugins/`
- Symlink architecture: `~/.claude/plugins/` ← `~/.ccs/shared/plugins/` ← `instance/plugins/`
- Install plugins once, use across GLM, GLMT, Kimi, and all Claude accounts
- Cross-platform support with Windows fallback (copy mode)

## [4.3.5] - 2025-11-22

### Changed
- **Deprecated Agent Cleanup**: Removed deprecated `ccs-delegator.md` agent file from installations
- Enhanced installation process to automatically clean up obsolete files
- Improved `ccs sync` command with migration logic for deprecated components

### Removed
- **ccs-delegator.md**: Agent file deprecated in favor of `ccs-delegation` skill (v4.3.2)
- Clean up of package copy in `~/.ccs/.claude/agents/ccs-delegator.md`
- Clean up of user symlink in `~/.claude/agents/ccs-delegator.md`

### Added
- Automatic migration marker system for tracking cleanup completion
- Intelligent backup system for user-modified deprecated files
- Version-aware migration logic following existing patterns

### Migration
- **Automatic**: Users upgrading from v4.3.2 or earlier will have deprecated files cleaned up automatically
- **Manual**: Run `ccs sync` to trigger cleanup manually
- **Backups**: User-modified files are backed up with timestamp before removal
- **Idempotent**: Cleanup is safe to run multiple times

### Technical Details
- Integrated into `npm postinstall` script for automatic cleanup on package updates
- Added to `ccs sync` command for manual cleanup operations
- Uses migration markers in `~/.ccs/.migrations/v435-delegator-cleanup`
- Follows existing SharedManager migration patterns for consistency

## [4.3.4] - 2025-11-22

  - Old: `/ccs:glm`, `/ccs:kimi`, `/ccs:glm:continue`, `/ccs:kimi:continue`
  - New: `/ccs` (auto-selects profile), `/ccs:continue` (auto-detects profile)
  - Override with flags: `/ccs --glm "task"`, `/ccs --kimi "task"`

### Changed
- Updated `--help` text across Node.js, Bash, and PowerShell implementations
- Updated delegation examples in README.md and workflow documentation
- Fixed CCS Doctor health checks to validate new command files
- Updated user configuration templates with new command syntax

### Added

### Migration
| Old Command | New Command |
|-------------|-------------|
| `/ccs:glm "task"` | `/ccs "task"` (or `/ccs --glm "task"`) |
| `/ccs:kimi "task"` | `/ccs "task"` (or `/ccs --kimi "task"`) |
| `/ccs:glm:continue` | `/ccs:continue` |
| `/ccs:kimi:continue` | `/ccs:continue` |

### Fixed
- Duplicate .claude/ resources across multiple profiles
- Installer logic now handles symlink creation during setup
- Orphaned `claude -p` processes after parent termination
- Slash commands broken by IMPORTANT safety prefix
- Slash commands detected as file paths (/home vs /cook)
