alchemmist codex

A terminal-native coding agent built on OpenAI Codex and kept in sync with upstream.

What's included

• The TUI uses the terminal palette and updates the composer, conversation history, plans, and diffs immediately when the terminal theme changes.
• The configurable startup cockpit identifies alchemmist codex, shows its exact build commit, and rotates fork-specific feature tips.
• Ctrl+S stashes the current prompt draft, persists it across restarts, and restores it on the next press.
• /subagents <prompt> explicitly enables subagents for one request; /subagents arms them for the next prompt.
• /statusline can show the number of active subagents, while /agents opens an overview of their work.
• Fast mode is process-local, resets to standard on every start or resume, and shows ⚡ in the status line while active.
• /cd <path> changes the current session's working directory without restarting Codex.
• /todo shows the complete plan, while a compact adaptive list of active items remains visible at the bottom of the TUI.
• /workflow runs configurable Python workflows with persistent state, per-agent models and reasoning, and parallel-agent support. The PR babysitter keeps CI and review feedback moving with fresh repair agents and forbids Quality Graph ignores.
• /tmux-command-log creates a separate tmux window containing Codex commands and their output.
• /context summarizes the model-visible context, while /system-prompt opens the complete latest logical model request in Neovim inside a new tmux window.
• /dump exports the full conversation to a responsive HTML file styled like alchemmist.xyz, with tool activity collapsed between messages.
• The composer and submitted user messages share a cyan vertical rail, making prompts easy to find throughout the conversation.
• Vim editing supports Insert, Normal, character/line/block Visual modes, Russian keyboard aliases, system-clipboard yanks, and terminal-native selection colors.
• Prompts interrupted before work begins return to the editor; later interruptions are shown without a noisy error message.
• Force pushes always require an explicit Yes or No selection in the TUI.
• Fixes include tmux pane resize redraws, focus-related flickering, and a stable Working animation.
• The root Makefile installs a local build or downloads ready-made macOS and Linux releases.
