## Why `thread/list` can filter direct children with `parentThreadId`, but clients cannot request an entire spawned subtree. Discovering every descendant requires repeated client-side requests and gives up the database's existing filtering and pagination path. ## What changed Experimental clients can use `ancestorThreadId` to return strict descendants at any depth while `parentThreadId` retains its direct-child meaning. The filters are mutually exclusive, the ancestor is excluded, and every result preserves its immediate `parentThreadId` so callers can reconstruct the tree. ## How it works - **Explicit relationship:** Internal list parameters distinguish direct children from transitive descendants without changing the meaning of `parentThreadId`. - **Existing graph:** Persisted parent-child spawn edges remain the source of truth, so descendant lookup needs no schema migration or ancestry cache. - **Indexed traversal:** A recursive SQLite query starts from the parent-edge index, walks each generation, and applies thread filters, sorting, and cursor pagination in the same database request. - **Reconstructable results:** The response stays flat and normally ordered while carrying each descendant's immediate parent. ## Verification Ran 550 tests across the protocol, state, rollout, and thread-store crates, then reran the four focused state, store, and app-server descendant-listing tests after the final diff reduction. Scoped Clippy and formatting checks passed. Stable and experimental schema generation was checked; the stable fixtures remain unchanged while the experimental schema includes the new field.
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.
