How it works

This skill checks if Ultrawork is linked to a Ralph loop. If not, it clears Ultrawork state files and deactivates the mode. If linked, it advises to use `/cancel-ralph` instead.

About this skill

Cancel Ultrawork

[ULTRAWORK CANCELLED]

The Ultrawork mode has been cancelled. Clearing state files.

MANDATORY ACTION

First, check if ultrawork is linked to an active Ralph loop:

cat .omc/ultrawork-state.json 2>/dev/null | jq -r '.linked_to_ralph // false'

If linked_to_ralph is true: Use /cancel-ralph instead to cancel both Ralph and its linked Ultrawork.

Otherwise, execute this command to cancel Ultrawork:

mkdir -p .omc && \
echo '{"active": false, "cancelled_at": "'$(date -Iseconds)'", "reason": "User cancelled via /cancel-ultrawork"}' > .omc/ultrawork-state.json && \
echo '{"active": false, "cancelled_at": "'$(date -Iseconds)'", "reason": "User cancelled via /cancel-ultrawork"}' > ~/.claude/ultrawork-state.json

After running this command, ultrawork mode will be deactivated and the HUD will update.

Note on Linked Modes

Since v3.0, Ralph automatically activates Ultrawork. If you see linked_to_ralph: true in the ultrawork state, it means Ultrawork was auto-activated by Ralph. In this case:

  • Use /cancel-ralph to cancel both modes
  • If you only cancel ultrawork, Ralph will continue but without parallel execution benefits

To Start Fresh

  • /ultrawork "task" - Start ultrawork only (standalone)
  • /ralph "task" - Start ralph with ultrawork (default)

When not to use it

  • When Ultrawork is linked to an active Ralph loop and only Ultrawork needs to be cancelled
  • When the user wants to start Ultrawork or Ralph
  • When the user wants to manually delete state files

Limitations

  • If `linked_to_ralph` is true, use `/cancel-ralph` instead
  • If only Ultrawork is cancelled while linked to Ralph, Ralph will continue without parallel execution benefits
  • The skill only deactivates Ultrawork mode; it does not start it

How it compares

This skill provides a guided process for cancelling Ultrawork, including checking for linked Ralph loops and clearing state files, unlike manually deleting files.

Automatically detect and maintain memory freshness by monitoring context staleness, significant code changes, task completions, and phase transitions. Proactively suggests and executes memory sync operations with user confirmation. Use when the user says "sync memory", "update context", or when the Skill detects that context is stale (>2 hours), significant changes have occurred (new commits), tasks completed, or major milestones reached. Replaces passive "context is stale" warnings with active maintenance.
