## Why `memory_summary.md` is injected into every session, so its value depends on staying compact, navigational, and easy to regenerate when the expected shape changes. The previous consolidation prompt encouraged a broad actionable inventory and allowed older summary structures to be patched in place, which makes it easier for stale or overly verbose summaries to keep accumulating. This change makes the summary format explicitly versioned and biases Phase 2 memory consolidation toward denser prompt-loaded context. ## What changed - Require `memory_summary.md` to begin with an exact `v1` header. - Teach consolidation to regenerate `memory_summary.md` from scratch when the header is missing or incompatible, while still allowing incremental updates to `MEMORY.md`. - Tighten the `memory_summary.md` instructions so it acts as a compact routing/index layer instead of a second handbook. - Lower `MEMORY_TOOL_DEVELOPER_INSTRUCTIONS_SUMMARY_TOKEN_LIMIT` from `5_000` to `2_500` so the runtime prompt budget matches the denser summary target. ## Verification Not run; this is a prompt/template update plus a prompt budget constant change.

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.
