Open-source CLI tool automates Codex context window management
A developer released a free, open-source CLI/TUI tool that handles the tedious work of managing what Codex sees in its context window. Instead of manually trimming or repasting content each session, the tool orchestrates it for you. The author is seeking community feedback.
Codex, like most AI coding assistants, has a fixed limit on how much text it can process at once — called a context window. As a conversation grows, older content gets cut off, and users often have to manually decide what to keep or re-paste. This tool automates that juggling act, letting you control what goes into and out of Codex's view without doing it by hand every time.
Unlike memory tools (which try to make Codex remember past sessions), this focuses on context orchestration — actively managing what Codex can see right now, in the current session. It supports both a CLI (command-line) and a TUI (a visual, keyboard-driven interface inside the terminal). It's open source, so anyone can use it for free or contribute improvements.
Key points
- Automates the repetitive task of trimming and managing Codex's context window each session
- Focuses on what Codex sees now (context orchestration), not long-term memory storage
- Supports both CLI and TUI interfaces for flexible use
- Free and open source — anyone can use or improve it
- Useful for solo developers who use Codex heavily and want to reduce manual overhead
