## Why Clients that display or coordinate spawned subagents need an authoritative snapshot of a thread's immediate spawned children when they connect to app-server or recover after missing live events. `thread/list` cannot query by parent, so clients must otherwise scan unrelated threads or reconstruct relationships from rollout history and transient events. The direct spawn relationship already exists in persisted `thread_spawn_edges` state. Review and Guardian threads do not participate in that lifecycle and are intentionally outside this filter's scope. ## What changed This adds an experimental `parentThreadId` filter to `thread/list`. Parent-filtered requests return direct spawned children from persisted state while preserving the existing response shape, explicit filters, sorting, and timestamp-only cursor behavior. The lookup does not read rollout transcripts or recursively return descendants. Supersedes #25112 with the narrower `thread/list` filter approach. ## How it works 1. An experimental client passes a valid thread ID as `parentThreadId`. 2. App-server routes the list through the existing thread-store and state-database boundaries. 3. SQLite selects threads whose IDs have a direct persisted spawn edge from that parent. 4. Omitted provider and source filters include all values; explicit filters keep ordinary `thread/list` semantics. 5. Grandchildren, Review threads, and Guardian threads are excluded. ## Verification State (144 tests), rollout (69 tests), and focused app-server thread-list (31 tests) suites passed. Scoped Clippy checks and repository formatting also passed. Coverage includes direct spawned children, omitted grandchildren, pagination, malformed IDs, mixed source kinds, explicit filters, and operation without rollout files.
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.
