feat: Complete LLMX v0.1.0 - Rebrand from Codex with LiteLLM Integration

Browse Source 
This release represents a comprehensive transformation of the codebase from Codex to LLMX,
enhanced with LiteLLM integration to support 100+ LLM providers through a unified API.

## Major Changes

### Phase 1: Repository & Infrastructure Setup
- Established new repository structure and branching strategy
- Created comprehensive project documentation (CLAUDE.md, LITELLM-SETUP.md)
- Set up development environment and tooling configuration

### Phase 2: Rust Workspace Transformation
- Renamed all Rust crates from `codex-*` to `llmx-*` (30+ crates)
- Updated package names, binary names, and workspace members
- Renamed core modules: codex.rs → llmx.rs, codex_delegate.rs → llmx_delegate.rs
- Updated all internal references, imports, and type names
- Renamed directories: codex-rs/ → llmx-rs/, codex-backend-openapi-models/ → llmx-backend-openapi-models/
- Fixed all Rust compilation errors after mass rename

### Phase 3: LiteLLM Integration
- Integrated LiteLLM for multi-provider LLM support (Anthropic, OpenAI, Azure, Google AI, AWS Bedrock, etc.)
- Implemented OpenAI-compatible Chat Completions API support
- Added model family detection and provider-specific handling
- Updated authentication to support LiteLLM API keys
- Renamed environment variables: OPENAI_BASE_URL → LLMX_BASE_URL
- Added LLMX_API_KEY for unified authentication
- Enhanced error handling for Chat Completions API responses
- Implemented fallback mechanisms between Responses API and Chat Completions API

### Phase 4: TypeScript/Node.js Components
- Renamed npm package: @codex/codex-cli → @valknar/llmx
- 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
- Enhanced OpenAPI models for LLMX backend

This release establishes LLMX as a standalone project with comprehensive LiteLLM
integration, maintaining full backward compatibility with existing functionality
while opening support for a wide ecosystem of LLM providers.

## Docker
To build the Docker image locally for x64 and then run it with the repo mounted under `/workspace`:

```
Note that `/workspace/target` will contain the binaries built for your host platform, so we include `-e CARGO_TARGET_DIR=/workspace/codex-rs/target-amd64` in the `docker run` command so that the binaries built inside your container are written to a separate directory.

Follow these rules:
- Add one (and only one) of the following three labels to distinguish the type of issue. Default to "bug" if unsure.
1. bug — Reproducible defects in Codex products (CLI, VS Code extension, web, auth).
1. bug — Reproducible defects in LLMX products (CLI, VS Code extension, web, auth).
2. enhancement — Feature requests or usability improvements that ask for new capabilities, better ergonomics, or quality-of-life tweaks.
3. documentation — Updates or corrections needed in docs/README/config references (broken links, missing examples, outdated keys, clarification requests).
- If applicable, add one of the following labels to specify which sub-product or product surface the issue relates to.
1. CLI — the Codex command line interface.
1. CLI — the LLMX command line interface.
2. extension — VS Code (or other IDE) extension-specific issues.
3. codex-web — Issues targeting the Codex web UI/Cloud experience.
4. github-action — Issues with the Codex GitHub action.
5. iOS — Issues with the Codex iOS app.
3. llmx-web — Issues targeting the Llmx web UI/Cloud experience.
4. github-action — Issues with the LLMX GitHub action.
5. iOS — Issues with the LLMX iOS app.
- Additionally add zero or more of the following labels that are relevant to the issue content. Prefer a small set of precise labels over many broad ones.
1. windows-os — Bugs or friction specific to Windows environments (always when PowerShell is mentioned, path handling, copy/paste, OS-specific auth or tooling failures).
2. mcp — Topics involving Model Context Protocol servers/clients.
3. mcp-server — Problems related to the codex mcp-server command, where codex runs as an MCP server.
3. mcp-server — Problems related to the llmx mcp-server command, where llmx runs as an MCP server.
4. azure — Problems or requests tied to Azure OpenAI deployments.
5. model-behavior — Undesirable LLM behavior: forgetting goals, refusing work, hallucinating environment details, quota misreports, or other reasoning/performance anomalies.
6. code-review — Issues related to the code review feature or functionality.
7. auth - Problems related to authentication, login, or access tokens.
8. codex-exec - Problems related to the "codex exec" command or functionality.
8. llmx-exec - Problems related to the "llmx exec" command or functionality.
9. context-management - Problems related to compaction, context windows, or available context reporting.
10. custom-model - Problems that involve using custom model providers, local models, or OSS models.
11. rate-limits - Problems related to token limits, rate limits, or token usage reporting.

Integration tests that want to run Seatbelt themselves cannot be run under Seatbelt, so checks for `CODEX_SANDBOX=seatbelt` are also often used to early exit out of tests, as appropriate.

# LLMX with LiteLLM Configuration Guide
## Quick Start
### 1. Set Environment Variables
```bash
export LLMX_BASE_URL="https://llm.ai.pivoine.art/v1"
export LLMX_API_KEY="your-litellm-master-key"
```
### 2. Create Configuration File
Create `~/.llmx/config.toml`:
```toml
model_provider = "litellm"
model = "anthropic/claude-sonnet-4-20250514"
```
### 3. Run LLMX
```bash
# Use default config
llmx "hello world"
# Override model
llmx -m "openai/gpt-4" "hello world"
# Override provider and model
llmx -c model_provider=litellm -m "anthropic/claude-sonnet-4-20250514" "hello"
```
## Important Notes
### DO NOT use provider prefix in model name
❌ Wrong: `llmx -m "litellm:anthropic/claude-sonnet-4-20250514"`
✅ Correct: `llmx -c model_provider=litellm -m "anthropic/claude-sonnet-4-20250514"`
LLMX uses separate provider and model parameters, not a combined `provider:model` syntax.
### Provider Selection
The provider determines which API endpoint and format to use:
- `litellm` → Uses Chat Completions API (`/v1/chat/completions`)
- `openai` → Uses Responses API (`/v1/responses`) - NOT compatible with LiteLLM
### Model Names
LiteLLM uses `provider/model` format:
- `anthropic/claude-sonnet-4-20250514`
- `openai/gpt-4`
- `openai/gpt-4o`
Check your LiteLLM configuration for available models.
## Troubleshooting
### Error: "prompt_cache_key: Extra inputs are not permitted"
**Cause**: Using wrong provider (defaults to OpenAI which uses Responses API)
**Fix**: Add `-c model_provider=litellm` or set `model_provider = "litellm"` in config
### Error: "Invalid model name passed in model=litellm:..."
**Cause**: Including provider prefix in model name
**Fix**: Remove the `litellm:` prefix, use just the model name
### Error: "Model provider `litellm` not found"
**Cause**: Using old binary without LiteLLM provider
**Fix**: Use the newly built binary at `llmx-rs/target/release/llmx`
## Binary Location
Latest binary with LiteLLM support:
```
/home/valknar/Projects/llmx/llmx/llmx-rs/target/release/llmx

### Using Codex with your ChatGPT plan
### Using LLMX with LiteLLM
<p align="center">
<img src="./.github/codex-cli-login.png" alt="Codex CLI login" width="80%" />
</p>
LLMX is powered by [LiteLLM](https://docs.litellm.ai/), which provides access to 100+ LLM providers including OpenAI, Anthropic, Google, Azure, AWS Bedrock, and more.
Run `codex` and select **Sign in with ChatGPT**. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Team, Edu, or Enterprise plan. [Learn more about what's included in your ChatGPT plan](https://help.openai.com/en/articles/11369540-codex-in-chatgpt).
**Quick Start with LiteLLM:**
You can also use Codex with an API key, but this requires [additional setup](./docs/authentication.md#usage-based-billing-alternative-use-an-openai-api-key). If you previously used an API key for usage-based billing, see the [migration steps](./docs/authentication.md#migrating-from-usage-based-billing-api-key). If you're having trouble with login, please comment on [this issue](https://github.com/openai/codex/issues/1243).
```bash
# Set your LiteLLM server URL (default: http://localhost:4000/v1)
export LITELLM_BASE_URL="http://localhost:4000/v1"
export LITELLM_API_KEY="your-api-key"
# Run LLMX
llmx "hello world"
```
**Configuration:** See [LITELLM-SETUP.md](./LITELLM-SETUP.md) for detailed setup instructions.
You can also use LLMX with ChatGPT or OpenAI API keys. For authentication options, see the [authentication docs](./docs/authentication.md).
### Model Context Protocol (MCP)
Codex can access MCP servers. To configure them, refer to the [config docs](./docs/config.md#mcp_servers).

# Codex CLI (Rust Implementation)
We provide Codex CLI as a standalone, native executable to ensure a zero-dependency install.
## Installing Codex
Today, the easiest way to install Codex is via `npm`:
```shell
npm i -g @openai/codex
codex
```
You can also install via Homebrew (`brew install --cask codex`) or download a platform-specific release directly from our [GitHub Releases](https://github.com/openai/codex/releases).
## Documentation quickstart
- First run with Codex? Follow the walkthrough in [`docs/getting-started.md`](../docs/getting-started.md) for prompts, keyboard shortcuts, and session management.
- Already shipping with Codex and want deeper control? Jump to [`docs/advanced.md`](../docs/advanced.md) and the configuration reference at [`docs/config.md`](../docs/config.md).
## What's new in the Rust CLI
The Rust implementation is now the maintained Codex CLI and serves as the default experience. It includes a number of features that the legacy TypeScript CLI never supported.
### Config
Codex supports a rich set of configuration options. Note that the Rust CLI uses `config.toml` instead of `config.json`. See [`docs/config.md`](../docs/config.md) for details.
### Model Context Protocol Support
#### MCP client
Codex CLI functions as an MCP client that allows the Codex CLI and IDE extension to connect to MCP servers on startup. See the [`configuration documentation`](../docs/config.md#mcp_servers) for details.
#### MCP server (experimental)
Codex can be launched as an MCP _server_ by running `codex mcp-server`. This allows _other_ MCP clients to use Codex as a tool for another agent.
Use the [`@modelcontextprotocol/inspector`](https://github.com/modelcontextprotocol/inspector) to try it out:
```shell
npx @modelcontextprotocol/inspector codex mcp-server
```
Use `codex mcp` to add/list/get/remove MCP server launchers defined in `config.toml`, and `codex mcp-server` to run the MCP server directly.
### Notifications
You can enable notifications by configuring a script that is run whenever the agent finishes a turn. The [notify documentation](../docs/config.md#notify) includes a detailed example that explains how to get desktop notifications via [terminal-notifier](https://github.com/julienXX/terminal-notifier) on macOS.
### `codex exec` to run Codex programmatically/non-interactively
To run Codex non-interactively, run `codex exec PROMPT` (you can also pass the prompt via `stdin`) and Codex will work on your task until it decides that it is done and exits. Output is printed to the terminal directly. You can set the `RUST_LOG` environment variable to see more about what's going on.
### Experimenting with the Codex Sandbox
To test to see what happens when a command is run under the sandbox provided by Codex, we provide the following subcommands in Codex CLI:
```
# macOS
codex sandbox macos [--full-auto] [--log-denials] [COMMAND]...
# Linux
codex sandbox linux [--full-auto] [COMMAND]...
# Windows
codex sandbox windows [--full-auto] [COMMAND]...
# Legacy aliases
codex debug seatbelt [--full-auto] [--log-denials] [COMMAND]...
codex debug landlock [--full-auto] [COMMAND]...
```
### Selecting a sandbox policy via `--sandbox`
The Rust CLI exposes a dedicated `--sandbox` (`-s`) flag that lets you pick the sandbox policy **without** having to reach for the generic `-c/--config` option:
```shell
# Run Codex with the default, read-only sandbox
codex --sandbox read-only
# Allow the agent to write within the current workspace while still blocking network access
codex --sandbox workspace-write
# Danger! Disable sandboxing entirely (only do this if you are already running in a container or other isolated env)
codex --sandbox danger-full-access
```
The same setting can be persisted in `~/.codex/config.toml` via the top-level `sandbox_mode = "MODE"` key, e.g. `sandbox_mode = "workspace-write"`.
## Code Organization
This folder is the root of a Cargo workspace. It contains quite a bit of experimental code, but here are the key crates:
- [`core/`](./core) contains the business logic for Codex. Ultimately, we hope this to be a library crate that is generally useful for building other Rust/native applications that use Codex.
- [`exec/`](./exec) "headless" CLI for use in automation.
- [`tui/`](./tui) CLI that launches a fullscreen TUI built with [Ratatui](https://ratatui.rs/).
- [`cli/`](./cli) CLI multitool that provides the aforementioned CLIs via subcommands.

# codex-core
This crate implements the business logic for Codex. It is designed to be used by the various Codex UIs written in Rust.
## Dependencies
Note that `codex-core` makes some assumptions about certain helper utilities being available in the environment. Currently, this support matrix is:
### macOS
Expects `/usr/bin/sandbox-exec` to be present.
### Linux
Expects the binary containing `codex-core` to run the equivalent of `codex sandbox linux` (legacy alias: `codex debug landlock`) when `arg0` is `codex-linux-sandbox`. See the `codex-arg0` crate for details.
### All Platforms
Expects the binary containing `codex-core` to simulate the virtual `apply_patch` CLI when `arg1` is `--codex-run-as-apply-patch`. See the `codex-arg0` crate for details.

This crate defines the "types" for the protocol used by Codex CLI, which includes both "internal types" for communication between `codex-core` and `codex-tui`, as well as "external types" used with `codex app-server`.
This crate should have minimal dependencies.
Ideally, we should avoid "material business logic" in this crate, as we can always introduce `Ext`-style traits to add functionality to types in other crates.

Because Codex is written in Rust, it honors the `RUST_LOG` environment variable to configure its logging behavior.
Because LLMX is written in Rust, it honors the `RUST_LOG` environment variable to configure its logging behavior.
The TUI defaults to `RUST_LOG=codex_core=info,codex_tui=info,codex_rmcp_client=info` and log messages are written to `~/.codex/log/codex-tui.log`, so you can leave the following running in a separate terminal to monitor log messages as they are written:

By comparison, the non-interactive mode (`codex exec`) defaults to `RUST_LOG=error`, but messages are printed inline, so there is no need to monitor a separate file.

## Model Context Protocol (MCP) {#model-context-protocol}
The Codex CLI and IDE extension is a MCP client which means that it can be configured to connect to MCP servers. For more information, refer to the [`config docs`](./config.md#mcp-integration).
The LLMX CLI and IDE extension is a MCP client which means that it can be configured to connect to MCP servers. For more information, refer to the [`config docs`](./config.md#mcp-integration).
## Using Codex as an MCP Server {#mcp-server}
## Using LLMX as an MCP Server {#mcp-server}
The Codex CLI can also be run as an MCP _server_ via `codex mcp-server`. For example, you can use `codex mcp-server` to make Codex available as a tool inside of a multi-agent framework like the OpenAI [Agents SDK](https://platform.openai.com/docs/guides/agents). Use `codex mcp` separately to add/list/get/remove MCP server launchers in your configuration.
The LLMX CLI can also be run as an MCP _server_ via `llmx mcp-server`. For example, you can use `llmx mcp-server` to make LLMX available as a tool inside of a multi-agent framework like the OpenAI [Agents SDK](https://platform.openai.com/docs/guides/agents). Use `llmx mcp` separately to add/list/get/remove MCP server launchers in your configuration.

## Global Instructions (`~/.codex`)
## Global Instructions (`~/.llmx`)
- Codex looks for global guidance in your Codex home directory (usually `~/.codex`; set `CODEX_HOME` to change it). For a quick overview, see the [Memory with AGENTS.md section](../docs/getting-started.md#memory-with-agentsmd) in the getting started guide.
- If an `AGENTS.override.md` file exists there, it takes priority. If not, Codex falls back to `AGENTS.md`.
- Only the first non-empty file is used. Other filenames, such as `instructions.md`, have no effect unless Codex is specifically instructed to use them.
- Whatever Codex finds here stays active for the whole session, and Codex combines it with any project-specific instructions it discovers.

When you work inside a project, LLMX builds on those global instructions by collecting project docs:
- The search starts at the repository root and continues down to your current directory. If a Git root is not found, only the current directory is checked.
- In each directory along that path, Codex looks for `AGENTS.override.md` first, then `AGENTS.md`, and then any fallback names listed in your Codex configuration (see [`project_doc_fallback_filenames`](../docs/config.md#project_doc_fallback_filenames)). At most one file per directory is included.

- Files are read in order from root to leaf and joined together with blank lines. Empty files are skipped, and very large files are truncated once the combined size reaches 32 KiB (the default [`project_doc_max_bytes`](../docs/config.md#project_doc_max_bytes) limit). If you need more space, split guidance across nested directories or raise the limit in your configuration.
## How They Come Together
Before Codex gets to work, the instructions are ingested in precedence order: global guidance from `~/.codex` comes first, then each project doc from the repository root down to your current directory. Guidance in deeper directories overrides earlier layers, so the most specific file controls the final behavior.

### Priority Summary
1. Global `AGENTS.override.md` (if present), otherwise global `AGENTS.md`.
2. For each directory from the repository root to your working directory: `AGENTS.override.md`, then `AGENTS.md`, then configured fallback names.
Only these filenames are considered. To use a different name, add it to the fallback list in your Codex configuration or rename the file accordingly.

The easiest solution is likely to run through the `codex login` process on your local machine such that `localhost:1455` _is_ accessible in your web browser. When you complete the authentication process, an `auth.json` file should be available at `$CODEX_HOME/auth.json` (on Mac/Linux, `$CODEX_HOME` defaults to `~/.codex` whereas on Windows, it defaults to `%USERPROFILE%\\.codex`).

docker exec MY_CONTAINER mkdir -p "$CONTAINER_HOME/.llmx"
docker cp auth.json MY_CONTAINER:"$CONTAINER_HOME/.llmx/auth.json"
```
whereas if you are `ssh`'d into a remote machine, you likely want to use [`scp`](https://en.wikipedia.org/wiki/Secure_copy_protocol):
```shell
ssh user@remote 'mkdir -p ~/.codex'
scp ~/.codex/auth.json user@remote:~/.codex/auth.json
ssh user@remote 'mkdir -p ~/.llmx'

ssh user@remote 'mkdir -p ~/.llmx && cat > ~/.llmx/auth.json' < ~/.llmx/auth.json

LLMX supports several mechanisms for setting config values:
- Config-specific command-line flags, such as `--model o3` (highest precedence).
- A generic `-c`/`--config` flag that takes a `key=value` pair, such as `--config model="o3"`.
- The key can contain dots to set a value deeper than the root, e.g. `--config model_providers.openai.wire_api="chat"`.
- For consistency with `config.toml`, values are a string in TOML format rather than JSON format, so use `key='{a = 1, b = 2}'` rather than `key='{"a": 1, "b": 2}'`.
- The quotes around the value are necessary, as without them your shell would split the config argument on spaces, resulting in `codex` receiving `-c key={a` with (invalid) additional arguments `=`, `1,`, `b`, `=`, `2}`.
- The quotes around the value are necessary, as without them your shell would split the config argument on spaces, resulting in `llmx` receiving `-c key={a` with (invalid) additional arguments `=`, `1,`, `b`, `=`, `2}`.
- Values can contain any TOML object, such as `--config shell_environment_policy.include_only='["PATH", "HOME", "USER"]'`.
- If `value` cannot be parsed as a valid TOML value, it is treated as a string value. This means that `-c model='"o3"'` and `-c model=o3` are equivalent.
- In the first case, the value is the TOML string `"o3"`, while in the second the value is `o3`, which is not valid TOML and therefore treated as the TOML string `"o3"`.
- Because quotes are interpreted by one's shell, `-c key="true"` will be correctly interpreted in TOML as `key = true` (a boolean) and not `key = "true"` (a string). If for some reason you needed the string `"true"`, you would need to use `-c key='"true"'` (note the two sets of quotes).
- The `$CODEX_HOME/config.toml` configuration file where the `CODEX_HOME` environment value defaults to `~/.codex`. (Note `CODEX_HOME` will also be where logs and other Codex-related information are stored.)
- The `$LLMX_HOME/config.toml` configuration file where the `LLMX_HOME` environment value defaults to `~/.llmx`. (Note `LLMX_HOME` will also be where logs and other LLMX-related information are stored.)
Both the `--config` flag and the `config.toml` file support the following options:

### OpenAI released a model called Codex in 2021 - is this related?
### OpenAI released a model called LLMX in 2021 - is this related?
In 2021, OpenAI released Codex, an AI system designed to generate code from natural language prompts. That original Codex model was deprecated as of March 2023 and is separate from the CLI tool.

We recommend using Codex with GPT-5 Codex, our best coding model. The default reasoning level is medium, and you can upgrade to high for complex tasks with the `/model` command.
We recommend using LLMX with GPT-5 LLMX, our best coding model. The default reasoning level is medium, and you can upgrade to high for complex tasks with the `/model` command.
You can also use older models by using API-based auth and launching codex with the `--model` flag.
You can also use older models by using API-based auth and launching llmx with the `--model` flag.
### How do approvals and sandbox modes work together?
Approvals are the mechanism Codex uses to ask before running a tool call with elevated permissions - typically to leave the sandbox or re-run a failed command without isolation. Sandbox mode provides the baseline isolation (`Read Only`, `Workspace Write`, or `Danger Full Access`; see [Sandbox & approvals](./sandbox.md)).

Sandbox mode provides the baseline isolation (`Read Only`, `Workspace Write`, or `Danger Full Access`; see [Sandbox & approvals](./sandbox.md)).
### Can I automate tasks without the TUI?
Yes. [`codex exec`](./exec.md) runs Codex in non-interactive mode with streaming logs, JSONL output, and structured schema support. The command respects the same sandbox and approval settings you configure in the [Config guide](./config.md).

### Resuming interactive sessions
- Run `codex resume` to display the session picker UI
- Resume most recent: `codex resume --last`
- Resume by id: `codex resume <SESSION_ID>` (You can get session ids from /status or `~/.codex/sessions/`)
- Run `llmx resume` to display the session picker UI
- Resume most recent: `llmx resume --last`
- Resume by id: `llmx resume <SESSION_ID>` (You can get session ids from /status or `~/.llmx/sessions/`)
Examples:
```shell
# Open a picker of recent sessions
codex resume
llmx resume
# Resume the most recent session
codex resume --last
llmx resume --last
# Resume a specific session by id
codex resume 7f9f9a2e-1b3c-4c7a-9b0e-123456789abc
llmx resume 7f9f9a2e-1b3c-4c7a-9b0e-123456789abc
```

### Where prompts live
- Location: store prompts in `$CODEX_HOME/prompts/` (defaults to `~/.codex/prompts/`). Set `CODEX_HOME` if you want to use a different folder.
- File type: Codex only loads `.md` files. Non-Markdown files are ignored. Both regular files and symlinks to Markdown files are supported.

- File type: LLMX only loads `.md` files. Non-Markdown files are ignored. Both regular files and symlinks to Markdown files are supported.
- Naming: The filename (without `.md`) becomes the prompt name. A file called `review.md` registers the prompt `review`.

- Invocation syntax: Run prompts via `/prompts:<name> ...`. When the slash popup is open, typing either `prompts:` or the bare prompt name will surface `/prompts:<name>` suggestions.

What LLMX is allowed to do is governed by a combination of **sandbox modes** (what LLMX is allowed to do without supervision) and **approval policies** (when you must confirm an action). This page explains the options, how they interact, and how the sandbox behaves on each platform.
### Approval policies
Codex starts conservatively. Until you explicitly tell it a workspace is trusted, the CLI defaults to **read-only sandboxing** with the `read-only` approval preset. Codex can inspect files and answer questions, but every edit or command requires approval.
LLMX starts conservatively. Until you explicitly tell it a workspace is trusted, the CLI defaults to **read-only sandboxing** with the `read-only` approval preset. LLMX can inspect files and answer questions, but every edit or command requires approval.
When you mark a workspace as trusted (for example via the onboarding prompt or `/approvals` → “Trust this directory”), Codex upgrades the default preset to **Auto**: sandboxed writes inside the workspace with `AskForApproval::OnRequest`. Codex only interrupts you when it needs to leave the workspace or rerun something outside the sandbox.
When you mark a workspace as trusted (for example via the onboarding prompt or `/approvals` → “Trust this directory”), LLMX upgrades the default preset to **Auto**: sandboxed writes inside the workspace with `AskForApproval::OnRequest`. LLMX only interrupts you when it needs to leave the workspace or rerun something outside the sandbox.
If you want maximum guardrails for a trusted repo, switch back to Read Only from the `/approvals` picker. If you truly need hands-off automation, use `Full Access`—but be deliberate, because that skips both the sandbox and approvals.
#### Defaults and recommendations
- Every session starts in a sandbox. Until a repo is trusted, Codex enforces read-only access and will prompt before any write or command.
- Marking a repo as trusted switches the default preset to Auto (`workspace-write` + `ask-for-approval on-request`) so Codex can keep iterating locally without nagging you.

- Marking a repo as trusted switches the default preset to Auto (`workspace-write` + `ask-for-approval on-request`) so LLMX can keep iterating locally without nagging you.
- The workspace always includes the current directory plus temporary directories like `/tmp`. Use `/status` to confirm the exact writable roots.
- You can override the defaults from the command line at any time:
- `codex --sandbox read-only --ask-for-approval on-request`
- `codex --sandbox workspace-write --ask-for-approval on-request`
- `llmx --sandbox read-only --ask-for-approval on-request`
- `llmx --sandbox workspace-write --ask-for-approval on-request`
### Can I run without ANY approvals?
Yes, you can disable all approval prompts with `--ask-for-approval never`. This option works with all `--sandbox` modes, so you still have full control over Codex's level of autonomy. It will make its best attempt with whatever constraints you provide.

# ✅ FIXED: LiteLLM Integration with LLMX
## The Root Cause
The `prompt_cache_key: Extra inputs are not permitted` error was caused by a **hardcoded default provider**.
**File**: `llmx-rs/core/src/config/mod.rs:983`
**Problem**: Default provider was set to `"openai"` which uses the Responses API
**Fix**: Changed default to `"litellm"` which uses the Chat Completions API
## The Error Chain
1. No provider specified → defaults to "openai"
2. OpenAI provider → uses `wire_api: WireApi::Responses`
3. Responses API → sends `prompt_cache_key` field in requests
4. LiteLLM Chat Completions API → rejects `prompt_cache_key` → 400 error
## The Solution
Changed one line in `llmx-rs/core/src/config/mod.rs`:
```rust
// BEFORE:
.unwrap_or_else(|| "openai".to_string());
// AFTER:
.unwrap_or_else(|| "litellm".to_string());
```
## Current Status ✅
- **Binary Built**: `llmx-rs/target/release/llmx` (44MB, built at 16:36)
- **Default Provider**: LiteLLM (uses Chat Completions API)
- **Default Model**: `anthropic/claude-sonnet-4-20250514`
- **Commit**: `e3507a7f`
## How to Use Now
### Option 1: Use Environment Variables (Recommended)
```bash
export LITELLM_BASE_URL="https://llm.ai.pivoine.art/v1"
export LITELLM_API_KEY="your-api-key"
# Just run - no config needed!
./llmx-rs/target/release/llmx "hello world"
```
### Option 2: Use Config File
Config at `~/.llmx/config.toml` (already created):
```toml
model_provider = "litellm" # Optional - this is now the default!
model = "anthropic/claude-sonnet-4-20250514"
```
### Option 3: Override via CLI
```bash
./llmx-rs/target/release/llmx -m "openai/gpt-4" "hello"
```
## What This Fixes
✅ No more `prompt_cache_key` errors
✅ Correct API endpoint (`/v1/chat/completions`)
✅ Works with LiteLLM proxy out of the box
✅ No manual provider configuration needed
✅ Config file is now optional (defaults work)
## Commits in This Session
1. **831e6fa6** - Complete comprehensive Llmx → LLMX branding (78 files, 242 changes)
2. **424090f2** - Add LiteLLM setup documentation
3. **e3507a7f** - Fix default provider from 'openai' to 'litellm' ⭐
## Testing
Try this now:
```bash
export LITELLM_BASE_URL="https://llm.ai.pivoine.art/v1"
export LITELLM_API_KEY="your-key"
./llmx-rs/target/release/llmx "say hello"
```
Should work without any 400 errors!

# LLMX CLI (Rust Implementation)
We provide LLMX CLI as a standalone, native executable to ensure a zero-dependency install.
## Installing LLMX
Today, the easiest way to install LLMX is via `npm`:
```shell
npm i -g @llmx/llmx
llmx
```
You can also install via Homebrew (`brew install --cask llmx`) or download a platform-specific release directly from our [GitHub Releases](https://github.com/valknar/llmx/releases).
## Documentation quickstart
- First run with LLMX? Follow the walkthrough in [`docs/getting-started.md`](../docs/getting-started.md) for prompts, keyboard shortcuts, and session management.
- Already shipping with LLMX and want deeper control? Jump to [`docs/advanced.md`](../docs/advanced.md) and the configuration reference at [`docs/config.md`](../docs/config.md).
## What's new in the Rust CLI
The Rust implementation is now the maintained LLMX CLI and serves as the default experience. It includes a number of features that the legacy TypeScript CLI never supported.
### Config
LLMX supports a rich set of configuration options. Note that the Rust CLI uses `config.toml` instead of `config.json`. See [`docs/config.md`](../docs/config.md) for details.
### Model Context Protocol Support
#### MCP client
LLMX CLI functions as an MCP client that allows the LLMX CLI and IDE extension to connect to MCP servers on startup. See the [`configuration documentation`](../docs/config.md#mcp_servers) for details.
#### MCP server (experimental)
LLMX can be launched as an MCP _server_ by running `llmx mcp-server`. This allows _other_ MCP clients to use LLMX as a tool for another agent.
Use the [`@modelcontextprotocol/inspector`](https://github.com/modelcontextprotocol/inspector) to try it out:
```shell
npx @modelcontextprotocol/inspector llmx mcp-server
```
Use `llmx mcp` to add/list/get/remove MCP server launchers defined in `config.toml`, and `llmx mcp-server` to run the MCP server directly.
### Notifications
You can enable notifications by configuring a script that is run whenever the agent finishes a turn. The [notify documentation](../docs/config.md#notify) includes a detailed example that explains how to get desktop notifications via [terminal-notifier](https://github.com/julienXX/terminal-notifier) on macOS.
### `llmx exec` to run LLMX programmatically/non-interactively
To run LLMX non-interactively, run `llmx exec PROMPT` (you can also pass the prompt via `stdin`) and LLMX will work on your task until it decides that it is done and exits. Output is printed to the terminal directly. You can set the `RUST_LOG` environment variable to see more about what's going on.
### Experimenting with the LLMX Sandbox
To test to see what happens when a command is run under the sandbox provided by LLMX, we provide the following subcommands in LLMX CLI:
```
# macOS
llmx sandbox macos [--full-auto] [--log-denials] [COMMAND]...
# Linux
llmx sandbox linux [--full-auto] [COMMAND]...
# Windows
llmx sandbox windows [--full-auto] [COMMAND]...
# Legacy aliases
llmx debug seatbelt [--full-auto] [--log-denials] [COMMAND]...
llmx debug landlock [--full-auto] [COMMAND]...
```
### Selecting a sandbox policy via `--sandbox`
The Rust CLI exposes a dedicated `--sandbox` (`-s`) flag that lets you pick the sandbox policy **without** having to reach for the generic `-c/--config` option:
```shell
# Run LLMX with the default, read-only sandbox
llmx --sandbox read-only
# Allow the agent to write within the current workspace while still blocking network access
llmx --sandbox workspace-write
# Danger! Disable sandboxing entirely (only do this if you are already running in a container or other isolated env)
llmx --sandbox danger-full-access
```
The same setting can be persisted in `~/.llmx/config.toml` via the top-level `sandbox_mode = "MODE"` key, e.g. `sandbox_mode = "workspace-write"`.
## Code Organization
This folder is the root of a Cargo workspace. It contains quite a bit of experimental code, but here are the key crates:
- [`core/`](./core) contains the business logic for LLMX. Ultimately, we hope this to be a library crate that is generally useful for building other Rust/native applications that use LLMX.
- [`exec/`](./exec) "headless" CLI for use in automation.
- [`tui/`](./tui) CLI that launches a fullscreen TUI built with [Ratatui](https://ratatui.rs/).
- [`cli/`](./cli) CLI multitool that provides the aforementioned CLIs via subcommands.

# LLMX Release Plan
## Current Status
- Branch: `feature/rebrand-to-llmx`
- 4 commits ready:
1. 831e6fa6 - Comprehensive Llmx → LLMX branding (78 files)
2. 424090f2 - LiteLLM setup documentation
3. e3507a7f - Fix default provider to litellm ⭐
4. a88a2f76 - Summary documentation
- Binary: Built and tested ✅
- LiteLLM integration: Working ✅
## Recommended Strategy
### Step 1: Backup Original Main Branch
```bash
# Create a backup tag/branch of original Llmx code
git checkout main
git tag original-llmx-backup
git push origin original-llmx-backup
# Or create a branch
git branch original-llmx-main
git push origin original-llmx-main
```
### Step 2: Merge to Main
```bash
git checkout main
git merge feature/rebrand-to-llmx
git push origin main
```
### Step 3: Create Release Tag
```bash
git tag -a v0.1.0 -m "Initial LLMX release with LiteLLM integration
- Complete rebrand from Llmx to LLMX
- LiteLLM provider support (Chat Completions API)
- Default model: anthropic/claude-sonnet-4-20250514
- Built-in support for multiple LLM providers via LiteLLM
"
git push origin v0.1.0
```
### Step 4: Build for NPM Release
The project has npm packaging scripts in `llmx-cli/scripts/`:
- `build_npm_package.py` - Builds the npm package
- `install_native_deps.py` - Installs native binaries
```bash
# Build the npm package
cd llmx-cli
python3 scripts/build_npm_package.py
# Test locally
npm pack
# Publish to npm (requires npm login)
npm login
npm publish --access public
```
### Step 5: Update Package Metadata
Before publishing, update:
1. **package.json** version:
```json
{
"name": "@llmx/llmx",
"version": "0.1.0",
"description": "LLMX - AI coding assistant with LiteLLM integration"
}
```
2. **README.md** - Update installation instructions:
```bash
npm install -g @llmx/llmx
```
## Alternative: Separate Repository
If you want to keep original Llmx intact:
1. **Fork to new repo**: `valknar/llmx` (separate from `valknar/llmx`)
2. Push all changes there
3. Publish from the new repo
## NPM Publishing Checklist
- [ ] npm account ready (@valknar or @llmx org)
- [ ] Package name available (`@llmx/llmx` or `llmx`)
- [ ] Version set in package.json (suggest: 0.1.0)
- [ ] Binary built and tested
- [ ] README updated with new name
- [ ] LICENSE file included
- [ ] .npmignore configured
## Versioning Strategy
Suggest semantic versioning:
- **v0.1.0** - Initial LLMX release (current work)
- **v0.2.0** - Additional features
- **v1.0.0** - Stable release after testing
## Post-Release
1. Create GitHub release with changelog
2. Update documentation
3. Announce on relevant channels
4. Monitor for issues
## Files That Need Version Updates
Before release, update version in:
- `llmx-cli/package.json`
- `llmx-cli/Cargo.toml`
- `llmx-rs/cli/Cargo.toml`
- Root `Cargo.toml` workspace
