## Summary - move `AppToolPolicyEvaluator` and the Apps config/requirements policy logic from `codex-core` into `codex-connectors` - resolve one immutable policy snapshot per exposure build and reuse it across every Codex Apps MCP tool - keep core as a thin adapter from MCP metadata to connector-owned policy input while preserving the call-time defense-in-depth check ## Why `build_mcp_tool_exposure` evaluates every Codex Apps tool on each sampling request. The old path rebuilt effective Apps configuration for every tool, and the policy implementation lived in the already-large core crate even though it is connector-specific. The connector-owned evaluator keeps the expensive config merge/decode out of the loop and gives core only the effective policy result it needs. ## Performance With the real 557-tool Apps corpus, `build_mcp_tool_exposure` measured 3.74 ms and 3.33 ms after the extraction (3.54 ms mean). The original path measured 807 ms mean, so the final result retains the 99.6% reduction. ## Validation - `cargo check -p codex-connectors -p codex-core` - `just test -p codex-connectors` — 15 passed - `just test -p codex-core --lib connectors` — 35 passed - `just test -p codex-core --lib mcp_tool_exposure` — 5 passed - `just test -p codex-core --lib mcp_tool_call` — 72 passed - `just bazel-lock-update` - `just bazel-lock-check` - `just fix -p codex-connectors` - `just fix -p codex-core` - `just fmt`

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.
