codex-eta 0.4.0

Time estimation for codex tasks. Sidecar that tracks progress and predicts completion time.

codex-eta

time estimation for codex tasks. shows how long things will take.

install

pip install codex-eta
codex mcp add eta-monitor -- codex-eta
codex-eta-install

Restart your shell, or run source ~/.zshrc / source ~/.bashrc.

The MCP server records completion signals. The sidecar does the ETA work by watching Codex session files; codex-eta-install adds shell wrappers that start the sidecar when you run codex or codx.

what happens

when you give codex a task:

1. the sidecar detects the active Codex rollout file
2. it estimates the number of tool calls with a local heuristic
3. a live progress bar can pop up in a separate terminal
4. progress updates as Codex writes session events
5. when done, you see actual time vs estimate

env vars

• ETA_NO_WATCHER=1 skip the popup progress window
• ETA_LLM_ESTIMATE=1 optionally ask codex exec for a second estimate based on the first 500 characters of the task prompt

files

• ~/.codex/eta_monitor_log.jsonl log of predictions vs actuals
• ~/.codex/eta_progress live progress (read by watcher)
• ~/.codex/eta_done_signal completion signal written by the MCP tool

uninstall

codex mcp remove eta-monitor
codex-eta-install --uninstall
pip uninstall codex-eta
