When I run in plan mode, I get the following output and it seems to just sit there. Should I expect more? jc@Gizmo:~/src/mage$ ralph plan.md plan
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ RALPH - Autonomous AI Development Loop ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Plan: plan.md Mode: plan Progress: plan_PROGRESS.md Commit: enabled Notify: Discord ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Exit conditions:
The model is hardcoded to sonnet on line 723-726 of ralph.sh:
echo "$PROMPT" | claude -p \ --dangerously-skip-permissions \ --model sonnet \ --verboseThere's no config option for it currently. Want me to make the model configurable via ~/.ralph.env with a RALPH_MODEL variable, defaulting to the current sonnet behavior? Then you'd just add:
export RALPH_MODEL="claude-opus-4-6"to your ~/.ralph.env to use Opus 4.6.
Yes, let's make it configurable.
The user wants to make the model configurable. This is a straightforward change:
RALPH_MODEL environment variable with a default of sonnetclaude -p command on line 723-726Let me also add it to the banner display so the user can see which model is being used.
Let me read the file first to make the edits.
Done. Three changes made:
RALPH_MODEL="${RALPH_MODEL:-sonnet}" — defaults to sonnet if not set$RALPH_MODEL instead of hardcoded sonnetTo use Opus 4.6, add this to your ~/.ralph.env:
export RALPH_MODEL="claude-opus-4-6"Or override it for a single run:
RALPH_MODEL=claude-opus-4-6 ralph plan.md planThe user is asking about the behavior of their ralph script when running in plan mode. They see the banner output but then it seems to hang. Let me look at the ralph.sh script to understand what's happening in plan mode.
Let me look at the ralph script to understand what's happening in plan mode.
Now I can see what happens after the banner. Let me trace the flow for plan mode:
Banner is printed (lines 542-575)
Notification is sent (line 579) - this calls notify.sh
Progress file is initialized if it doesn't exist (lines 582-593)
Lock is acquired (lines 628-638)
Main loop starts (line 643)
It checks is_done - probably not done yet
Iteration counter increments
Prompt is built from template
Claude CLI is invoked via echo "$PROMPT" | claude -p --dangerously-skip-permissions --model sonnet --verbose
After the banner, the script sends a Discord notification, acquires a lock, prints status messages, then pipes the prompt to claude -p which is likely where the delay occurs - the CLI is processing the plan request.
The notification step could be a culprit if the webhook is slow or failing, but more likely the user is just waiting for Claude to process the plan through the CLI.
Looking at the actual output the user showed, it stops right after printing the exit conditions, which means the hang happens during the notification call or the lock acquisition that follows. Let me trace through the notify.sh script to see if there's a blocking issue there. either at the notify call or when acquiring the lock. Let me look at the notify.sh script to see if that's where it's hanging.
The script is working - it's just processing. After the banner and exit conditions, it does several things before showing visible output:
claude -p --dangerously-skip-permissions --model sonnet --verbose piping in the promptThe most likely reason it appears to hang is:
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 filesYou 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:
plan_PROGRESS.md file was created in your working directoryls /tmp/ralph_*.lockclaude process is running: ps aux | grep claudeIf 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.
I want to use the latest model - opus 4.6. Is that something I can set?
The user wants to change the model from sonnet to opus 4.6. Looking at line 723-726 of ralph.sh:
echo "$PROMPT" | claude -p \ --dangerously-skip-permissions \ --model sonnet \ --verbose > "$claude_output_file" 2>"$claude_error_file" || claude_exit_code=$?The model is hardcoded to sonnet. There's no configuration option or environment variable for it. The user would need to either:
Let me check if there's any existing config mechanism for the model - maybe in constants.sh or the .ralph.env file.
echo "$PROMPT" | claude -p \ --dangerously-skip-permissions \ --model sonnet \ --verboseexport RALPH_MODEL="claude-opus-4-6"export RALPH_MODEL="claude-opus-4-6"RALPH_MODEL=claude-opus-4-6 ralph plan.md planecho "$PROMPT" | claude -p \ --dangerously-skip-permissions \ --model sonnet \ --verbose > "$claude_output_file" 2>"$claude_error_file" || claude_exit_code=$?
