## Why Dynamic tools are defined at thread start and already stored in rollout `SessionMeta`, which restores resumed and forked sessions. Persisting the same tools through SQLite creates a second runtime persistence path that is unnecessary prework for the explicit namespace refactor. ## What changed - Restore missing thread-start dynamic tools directly from rollout history, including when SQLite is enabled. - Remove SQLite dynamic-tool reads, writes, backfill, and thread metadata patch plumbing. - Add SQLite-enabled resume integration coverage that verifies a rollout-defined dynamic tool is still sent after resume. ## Compatibility The existing `thread_dynamic_tools` table is intentionally not dropped even though it's now unused. Older Codex binaries are allowed to open databases migrated by newer binaries and still reference this table; dropping it would break that mixed-version path. See [here](https://github.com/openai/codex/blob/main/codex-rs/state/src/migrations.rs#L10-L11). ## Verification - `just test -p codex-state -p codex-rollout -p codex-thread-store` - `just test -p codex-core --test all resume_restores_dynamic_tools_from_rollout_with_sqlite_enabled`
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
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# 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.
