Wrong -- system pip blocked on Python 3.12+ (PEP 668):
pip3 install some-tool # externally-managed-environment
Right -- use Homebrew or pipx:
brew install some-tool
pipx install some-python-app
Wrong -- complex regex in zsh triggers parse errors:
grep -oP '(?<=version":")[^"]+' package.json
# zsh: event not found
Right -- use built-in Grep tool, or wrap in bash:
bash -c 'grep -oP '"'"'(?<=version":")[^"]+'"'"' package.json'
Wrong -- run script directly (crashes if dir has .Codex/):
<key>ProgramArguments</key>
<array>
<string>/project/scripts/agent.sh</string>
</array>
Right -- bash wrapper + resource limits + environment vars:
<key>ProgramArguments</key>
<array>
<string>/bin/bash</string>
<string>-c</string>
<string>exec /bin/bash /project/scripts/agent.sh</string>
</array>

Wrong -- test from terminal (masks launchd-specific failures):
./scripts/agent.sh # works in terminal, fails silently under launchd
Right -- test with launchctl:
launchctl start com.yourorg.agent
launchctl list | grep yourorg # check actual exit status
