Enable Using Latest Model Version Opus 4.6Public

Let me look at the ralph script to understand what's happening in plan mode.

The script is working - it's just processing. After the banner and exit conditions, it does several things before showing visible output:

1. Line 579: Sends a Discord start notification (with retry logic - up to 3 attempts with exponential backoff)
2. Lines 582-593: Creates the progress file
3. Lines 628-638: Acquires a file lock
4. Line 640: Prints "Lock acquired: ..."
5. Line 665: Prints "ITERATION 1"
6. Line 723-726: Runs claude -p --dangerously-skip-permissions --model sonnet --verbose piping in the prompt

The most likely reason it appears to hang is:

• The Discord notification on line 579 could be slow (each retry waits 2s, 4s, 8s if failing), OR
• The claude -p command on line 723 takes time to process - it's running Claude in non-interactive pipe mode, which can take 30+ seconds with no visible output since stdout/stderr go to temp files

You should eventually see "Lock acquired", then "ITERATION 1", then silence while Claude processes. After Claude finishes, you'll see its output and then the "Planning complete!" banner.

If you want to verify it's not truly stuck, you can:

• Check if a plan_PROGRESS.md file was created in your working directory
• Look for the lock file: ls /tmp/ralph_*.lock
• Check if a claude process is running: ps aux | grep claude

If the Discord webhook is misconfigured or unreachable, that alone could add ~14 seconds of delay (3 retries with exponential backoff) before the script moves on. You could also try running with notifications disabled to see if that's the bottleneck.

The model is hardcoded to sonnet on line 723-726 of ralph.sh:

There's no config option for it currently. Want me to make the model configurable via ~/.ralph.env with a RALPH_MODEL variable, defaulting to the current sonnet behavior? Then you'd just add:

export RALPH_MODEL="claude-opus-4-6"

to your ~/.ralph.env to use Opus 4.6.

Done. Three changes made:

1. Default variable (line 175): RALPH_MODEL="${RALPH_MODEL:-sonnet}" — defaults to sonnet if not set
2. Banner display (line 553): Shows the model in the startup banner
3. Claude invocation (line 726): Uses $RALPH_MODEL instead of hardcoded sonnet

To use Opus 4.6, add this to your ~/.ralph.env:

export RALPH_MODEL="claude-opus-4-6"

Or override it for a single run:

RALPH_MODEL=claude-opus-4-6 ralph plan.md plan
