- Updated TypeScript SDK to use new LLMX APIs and endpoints
- Fixed all TypeScript compilation and linting errors
- Updated SDK tests to support both API backends
- Enhanced mock server to handle multiple API formats
- Updated build scripts for cross-platform packaging

### Phase 5: Configuration & Documentation
- Updated all configuration files to use LLMX naming
- Rewrote README and documentation for LLMX branding
- Updated config paths: ~/.codex/ → ~/.llmx/
- Added comprehensive LiteLLM setup guide
- Updated all user-facing strings and help text
- Created release plan and migration documentation

### Phase 6: Testing & Validation
- Fixed all Rust tests for new naming scheme
- Updated snapshot tests in TUI (36 frame files)
- Fixed authentication storage tests
- Updated Chat Completions payload and SSE tests
- Fixed SDK tests for new API endpoints
- Ensured compatibility with Claude Sonnet 4.5 model
- Fixed test environment variables (LLMX_API_KEY, LLMX_BASE_URL)

### Phase 7: Build & Release Pipeline
- Updated GitHub Actions workflows for LLMX binary names
- Fixed rust-release.yml to reference llmx-rs/ instead of codex-rs/
- Updated CI/CD pipelines for new package names
- Made Apple code signing optional in release workflow
- Enhanced npm packaging resilience for partial platform builds
- Added Windows sandbox support to workspace
- Updated dotslash configuration for new binary names

### Phase 8: Final Polish
- Renamed all assets (.github images, labels, templates)
- Updated VSCode and DevContainer configurations
- Fixed all clippy warnings and formatting issues
- Applied cargo fmt and prettier formatting across codebase
- Updated issue templates and pull request templates
- Fixed all remaining UI text references

## Technical Details

**Breaking Changes:**
- Binary name changed from `codex` to `llmx`
- Config directory changed from `~/.codex/` to `~/.llmx/`
- Environment variables renamed (CODEX_* → LLMX_*)
- npm package renamed to `@valknar/llmx`

**New Features:**
- Support for 100+ LLM providers via LiteLLM
- Unified authentication with LLMX_API_KEY
- Enhanced model provider detection and handling
- Improved error handling and fallback mechanisms

**Files Changed:**
- 578 files modified across Rust, TypeScript, and documentation
- 30+ Rust crates renamed and updated
- Complete rebrand of UI, CLI, and documentation
- All tests updated and passing

**Dependencies:**
- Updated Cargo.lock with new package names
- Updated npm dependencies in llmx-cli

Migration to pnpm

This project has been migrated from npm to pnpm to improve dependency management and developer experience.

Why pnpm?

Faster installation: pnpm is significantly faster than npm and yarn
Disk space savings: pnpm uses a content-addressable store to avoid duplication
Phantom dependency prevention: pnpm creates a strict node_modules structure
Native workspaces support: simplified monorepo management

How to use pnpm

Installation

# Global installation of pnpm
npm install -g pnpm@10.8.1

# Or with corepack (available with Node.js 22+)
corepack enable
corepack prepare pnpm@10.8.1 --activate

Common commands

npm command	pnpm equivalent
`npm install`	`pnpm install`
`npm run build`	`pnpm run build`
`npm test`	`pnpm test`
`npm run lint`	`pnpm run lint`

Workspace-specific commands

Action	Command
Run a command in a specific package	`pnpm --filter @llmx/llmx run build`
Install a dependency in a specific package	`pnpm --filter @llmx/llmx add lodash`
Run a command in all packages	`pnpm -r run test`

Monorepo structure

llmx/
├── pnpm-workspace.yaml    # Workspace configuration
├── .npmrc                 # pnpm configuration
├── package.json           # Root dependencies and scripts
├── llmx-cli/             # Main package
│   └── package.json       # llmx-cli specific dependencies
└── docs/                  # Documentation (future package)

Configuration files

pnpm-workspace.yaml: Defines the packages included in the monorepo
.npmrc: Configures pnpm behavior
Root package.json: Contains shared scripts and dependencies

CI/CD

CI/CD workflows have been updated to use pnpm instead of npm. Make sure your CI environments use pnpm 10.8.1 or higher.

Known issues

If you encounter issues with pnpm, try the following solutions:

Remove the node_modules folder and pnpm-lock.yaml file, then run pnpm install
Make sure you're using pnpm 10.8.1 or higher
Verify that Node.js 22 or higher is installed
