## Summary Persisted subagent parent/child topology currently leaks through `StateRuntime`'s SQLite-specific thread-spawn helpers. This PR introduces a narrow `AgentGraphStore` boundary so follow-up work can route graph operations through a local or remote store without coupling orchestration code directly to the state DB graph API. ## Changes - Adds the new `codex-agent-graph-store` crate. - Defines a flat `AgentGraphStore` trait for the v1 graph surface: upsert edge, set edge status, list direct children, and list descendants. - Adds public graph types for `ThreadSpawnEdgeStatus`, `AgentGraphStoreError`, and `AgentGraphStoreResult`. - Implements `LocalAgentGraphStore` on top of an existing `codex_state::StateRuntime`, preserving today's SQLite-backed `thread_spawn_edges` behavior. - Registers the crate in Cargo/Bazel metadata. This PR only adds the local contract and implementation; call-site migration and the remote gRPC store are left to the follow-up PRs in the stack. ## Testing - `cargo test -p codex-agent-graph-store` The new unit tests cover local parity with the existing `StateRuntime` graph methods, `Open`/`Closed` filtering, status updates, and stable breadth-first descendant ordering.
npm i -g @openai/codex
or brew install --cask codex
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
