Run a RALPH Plan

Execute an existing backend-ralph-plan using the Ralph Wiggum Loop.

What To Do

When the user runs /plan-directory:run <slug>:

Step 1: Find the Plan

Check these locations in order using Glob:

• docs/plans/<slug>/RALPH-PROMPT.md
• plans/<slug>/RALPH-PROMPT.md
• <slug>/RALPH-PROMPT.md (if user is already in a plans directory)

If not found, tell the user and suggest running /plan-directory:backend-ralph-plan.

Step 2: Extract the Completion Promise

Use Read to get RALPH-PROMPT.md contents, then find this pattern:

<promise>...</promise>

Extract the text between the tags. This is the completion promise.

Example: If the prompt contains <promise>ALL 4 USER-PREFERENCES TASKS COMPLETE</promise>, the completion promise is ALL 4 USER-PREFERENCES TASKS COMPLETE.

Step 3: Parse Max Iterations

• If user provided --max-iterations N, use N
• Otherwise, default to 100

Step 4: Invoke Ralph Loop

Use the Skill tool to invoke ralph-wiggum:ralph-loop:

skill: "ralph-wiggum:ralph-loop"
args: <prompt-content> --completion-promise "<extracted promise>" --max-iterations <N>

Where <prompt-content> is the full content of RALPH-PROMPT.md that you read in Step 2.

Note: The Skill tool should handle multi-line content. If it doesn't work properly, fall back to telling the user to run manually:

cd <plan-directory>
/ralph-wiggum:ralph-loop "$(cat RALPH-PROMPT.md)" \
  --completion-promise "<promise>" \
  --max-iterations <N>

Step 5: Confirm to User

After invoking, tell the user:

• Ralph loop has started
• It will iterate through the tasks
• Progress is saved via git commits
• Loop ends when the promise is output or max iterations reached
• They can use /ralph-wiggum:cancel-ralph to stop early

Examples

/plan-directory:run user-preferences
/plan-directory:run manager-weekly-digest --max-iterations 50
/plan-directory:run notification-service

Error Handling

Plan not found:

Could not find plan "xyz". Looked in:

• docs/plans/xyz/RALPH-PROMPT.md
• plans/xyz/RALPH-PROMPT.md

Run /plan-directory:backend-ralph-plan to create a new plan.

No completion promise found:

Warning: No <promise>...</promise> tag found in RALPH-PROMPT.md. Ralph will run until max iterations (N) without a completion signal. Continue anyway? [Proceed / Cancel]
