## Intent Follow up on #26205 by avoiding unnecessary filesystem canonicalization during `AGENTS.md` discovery. The configured working directory is already absolute, and canonicalization incorrectly switches symlinked workspaces from their logical parent hierarchy to the target's hierarchy. ## User-facing behavior For a symlinked working directory such as: ```text test-root/ |-- logical-repo/ | |-- AGENTS.md ("logical parent doc") | `-- workspace ------------> physical-repo/workspace/ `-- physical-repo/ |-- AGENTS.md ("physical parent doc") `-- workspace/ `-- AGENTS.md ("workspace doc") ``` Before this change, Codex canonicalized `logical-repo/workspace` to `physical-repo/workspace` before discovery. It therefore loaded `physical-repo/AGENTS.md` and `physical-repo/workspace/AGENTS.md`, ignoring the instructions from the repository through which the user entered the workspace. After this change, ancestor discovery walks the configured logical path, so Codex loads `logical-repo/AGENTS.md`. Opening `logical-repo/workspace/AGENTS.md` still follows the symlink through the host filesystem, so the workspace document is also loaded. `physical-repo/AGENTS.md` is not loaded. ## Implementation Use the logical absolute working directory when discovering project instructions and reporting instruction sources. Filesystem reads still follow the working-directory symlink, so an `AGENTS.md` in the target workspace continues to load while ancestor discovery uses the symlink's parents. ## Validation Added integration coverage proving that discovery loads the logical parent's instructions and the target workspace's instructions, but not the target parent's instructions.

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.
