## This PR
Remote plugin analytics cannot rely only on the in-memory
installed-plugin snapshot because that snapshot is refreshed
asynchronously after startup. This PR persists the authoritative backend
identity alongside each cached remote plugin bundle so later consumers
can resolve it without a network request.
### Behavior
- Store Codex-owned remote installation metadata in an atomic
`.codex-remote-plugin-install.json` sidecar under the plugin cache root.
- Use a versioned, snake_case schema:
```json
{
"schema_version": 1,
"remote_plugin_id": "plugins~Plugin_..."
}
```
- Write the metadata during remote bundle installation.
- Backfill it when bundle sync finds an already-current cached bundle.
- Clear it when a generic/local install replaces the cache.
- Let existing uninstall and stale-cache removal delete it with the
plugin cache root.
- Reject unsupported schema versions rather than silently misreading
future formats.
This PR does not change analytics serialization or event behavior.
### Review surface
The implementation is limited to four `codex-core-plugins` files:
- `store.rs`: owns the versioned sidecar read/write/remove lifecycle.
- `remote_bundle.rs`: persists the backend ID after a remote bundle
install.
- `remote/remote_installed_plugin_sync.rs`: backfills metadata for an
already-current cached bundle.
- Tests cover the storage lifecycle and both remote write paths.
## Testing / Validation
### Automated
- `just test -p codex-core-plugins` (268 tests passed)
- `just fix -p codex-core-plugins` passes with one pre-existing
`large_enum_variant` warning in `manifest.rs`.
- Coverage verifies the exact filename and JSON schema, identity
replacement, local reinstall clearing, uninstall cleanup, remote bundle
installation, unsupported schema rejection, and installed-plugin sync
backfill.
### Live manual validation
Validated the production app-server RPC path with an isolated temporary
`CODEX_HOME` and the PR-built Codex binary. The app-server communicated
over stdio and did not bind a port.
Test plugin: `plugins~Plugin_b80dd84519148191a409cde181c9b3d6`
(`build-macos-apps@openai-curated-remote`).
1. Confirmed `plugin/read` initially reported the plugin uninstalled.
2. Installed it through `plugin/install` and confirmed version `0.1.4`
was cached.
3. Verified
`$CODEX_HOME/plugins/cache/openai-curated-remote/build-macos-apps/.codex-remote-plugin-install.json`
was created beside the `0.1.4/` bundle directory with mode `0600` and
the expected contents:
```json
{
"schema_version": 1,
"remote_plugin_id": "plugins~Plugin_b80dd84519148191a409cde181c9b3d6"
}
```
4. Deleted only the sidecar, restarted the app-server, and confirmed
installed-plugin startup sync recreated it with the same contents.
5. Uninstalled through `plugin/uninstall`, confirmed `plugin/read`
returned `installed: false`, and verified the local plugin cache root
was removed.
6. Restored the account's original uninstalled state and removed the
isolated home and copied credentials.

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.
