Follow-up to #27356. ## Stack note This PR changes Codex's internal dynamic-tool shape while leaving `thread/start` unchanged. App-server therefore converts the existing per-tool input into explicit functions and namespaces before passing it to core. [#27371](https://github.com/openai/codex/pull/27371) updates `thread/start` to use the same explicit shape and removes this temporary conversion. ## Why Dynamic tools repeat namespace metadata on every function. Core should keep one explicit namespace with its member tools so descriptions and membership stay consistent across sessions and runtime planning. ## What changed - Represent dynamic tools as top-level functions or explicit namespaces in protocol and session state. - Read old flat rollout metadata and write the canonical hierarchy. - Flatten namespace members only when registering callable tools. - Keep `thread/start.dynamicTools` flat for now and normalize it at the app-server boundary. New builds can read old rollout metadata. Older builds cannot read newly written hierarchical metadata. ## Test plan - `just test -p codex-app-server thread_start_normalizes_legacy_dynamic_tools_into_model_request` - `just test -p codex-protocol session_meta_normalizes_legacy_dynamic_tools` - `just test -p codex-core resume_restores_dynamic_tools_from_rollout_with_sqlite_enabled` - `just test -p codex-core tool_search_returns_deferred_dynamic_tool_and_routes_follow_up_call` - `just test -p codex-core code_mode_can_call_hidden_dynamic_tools` - `just test -p codex-tools`

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.
