Agent IDE — Codex fork for AI-native development environment

## Why
We need a way to auto-reject specific approval prompt categories without
switching all approvals off.
The goal is to let users independently control:
- sandbox escalation approvals,
- execpolicy `prompt` rule approvals,
- MCP elicitation prompts.
## What changed
- Added a new primary approval mode in `protocol/src/protocol.rs`:
```rust
pub enum AskForApproval {
// ...
Reject(RejectConfig),
// ...
}
pub struct RejectConfig {
pub sandbox_approval: bool,
pub rules: bool,
pub mcp_elicitations: bool,
}
```
- Wired `RejectConfig` semantics through approval paths in `core`:
- `core/src/exec_policy.rs`
- rejects rule-driven prompts when `rules = true`
- rejects sandbox/escalation prompts when `sandbox_approval = true`
- preserves rule priority when both rule and sandbox prompt conditions
are present
- `core/src/tools/sandboxing.rs`
- applies `sandbox_approval` to default exec approval decisions and
sandbox-failure retry gating
- `core/src/safety.rs`
- keeps `Reject { all false }` behavior aligned with `OnRequest` for
patch safety
- rejects out-of-root patch approvals when `sandbox_approval = true`
- `core/src/mcp_connection_manager.rs`
- auto-declines MCP elicitations when `mcp_elicitations = true`
- Ensured approval policy used by MCP elicitation flow stays in sync
with constrained session policy updates.
- Updated app-server v2 conversions and generated schema/TypeScript
artifacts for the new `Reject` shape.
## Verification
Added focused unit coverage for the new behavior in:
- `core/src/exec_policy.rs`
- `core/src/tools/sandboxing.rs`
- `core/src/mcp_connection_manager.rs`
- `core/src/safety.rs`
- `core/src/tools/runtimes/apply_patch.rs`
Key cases covered include rule-vs-sandbox prompt precedence, MCP
auto-decline behavior, and patch/sandbox retry behavior under
`RejectConfig`.

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.
Using Codex with your ChatGPT plan
Run codex and select Sign in with ChatGPT. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Team, Edu, or Enterprise plan. Learn more about what's included in your ChatGPT plan.
You can also use Codex with an API key, but this requires additional setup.
