What it is

Codex CLI is a standalone, locally-running coding agent from OpenAI that executes in your terminal. It provides AI-powered code generation and completion capabilities directly on your machine, with integration options for ChatGPT plans or API keys. The core project is written in Rust (64MB+) with TypeScript/Node.js wrappers, enabling cross-platform distribution via npm, Homebrew, and standalone installers. Monorepo structure: codex-rs/ contains the Rust core (with cargo-based agent-graph-store submodule), codex-cli/ wraps it as a Node.js CLI entry point (bin/codex.js), and bazel/ contains build rules, toolchains, and platform-specific logic. The Bazel build system manages cross-platform…

Start here

Read these in order:

  • codex-rs/app-server-protocol/schema/typescript/serde_json/JsonValue.ts — Foundation: doesn't import anything internally and is imported by 8 other files. Read first to learn the vocabulary.
  • codex-rs/app-server-protocol/schema/typescript/ThreadId.ts — Foundation: imported by 5, no internal dependencies of its own.
  • codex-rs/app-server-protocol/schema/typescript/v2/AccountUpdatedNotification.ts — Built on the foundation; imported by 2 downstream files.
  • codex-rs/app-server-protocol/schema/typescript/FuzzyFileSearchResult.ts — Built on the foundation; imported by 2 downstream files.
  • codex-rs/app-server-protocol/schema/typescript/ReviewDecision.ts — Layer 2 — application-level code that wires the lower layers together.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Verify the exact Node.js and Rust toolchain requirements in codex-rs/Cargo.toml and codex-cli/package.json before starting. Clone the repository: git clone https://github.com/openai/codex.git && cd codex. Install Node…

Daily commands:

From repository root: cd codex-cli && pnpm install && pnpm build (or use installed binary directly). Then run codex or node bin/codex.js to start the CLI. For development: cd codex-rs && cargo build --dev to com…

…shortened for this brief.

Key cautions & unknowns

  • Critical runtime dependency on OpenAI authentication (ChatGPT account or API key)—CLI will not function without valid credentials. Build system uses Bazel (not Make or npm scripts alone), requiring Bazel installation.…
  • Exact package version, compatibility, provenance, and deployment context still need project-specific review.
