Codex Issue Runner

Codex Issue Runner

Overview

Automates spinning up OpenAI Codex CLI agents in SpeakMCP workspace slots to work on GitHub issues and PRs. Each slot is an independent workspace that can run one Codex agent at a time.

Slot Architecture

• Slots are at /Users/ajjoobandi/Development/SpeakMCP-Workspaces/slot-N (N=1 to 5)
• Each slot is a git clone of the SpeakMCP repo
• Max 5 concurrent Codex agents

Workflow

Step 1: Identify Available Slots

Use iterm:list_sessions to see which slots are occupied. Look for session names containing slot-N.

Step 2: Prepare the Slot

If the slot doesn't have an iTerm window, create one with iterm:create_window. Navigate to the slot directory and reset to main:

cd ~/Development/SpeakMCP-Workspaces/slot-N
gitcm

The gitcm alias runs git fetch && git checkout main && git pull.

Step 3: Launch Codex

Type codex and press ENTER in the terminal. Wait for the Codex UI to appear (look for the prompt box with model info).

Step 4: Submit the Task

Write a clear task description referencing the issue number. Always instruct Codex to read the full issue first:

Work on issue #N - [brief description]. First read the issue by running `gh issue view N` to get full context, then implement the fix.

Press ENTER to submit.

Step 5: Verify Submission

Wait 2-3 seconds, then read terminal output to confirm Codex is working (look for "Working" status).

Task Formatting Tips

• Always tell Codex to read the issue/PR first with gh issue view N or gh pr view N
• Give a one-line summary so Codex has initial context
• For PRs, use gh pr view N and gh pr diff N to understand existing changes

Monitoring

• Use iterm:read_terminal_output with the session ID to check progress
• Codex shows "Working (Ns)" while processing
• Press ESC to interrupt if needed

After Codex Finishes

Codex will make changes locally. You may want to:

1. Review changes: git diff
2. Create a branch: git checkout -b fix/issue-N-description
3. Commit and push: git add . && git commit -m "fix: description" && git push
4. Create PR: gh pr create --title "Fix #N: description" --body "Closes #N" Or run www "description" which automates the PR workflow.

Common Issues

• If Codex fails to connect to GitHub, check internet connection
• If slot is dirty, run git stash or git reset --hard before gitcm
• If Codex hangs, press ESC and retry
