At a glance

Detects which autonomous OMG mode is currently active - Autopilot, Ralph, Ultrawork, UltraQA, Team or Self-Improve - and shuts it down cleanly.

  • Works in 2 steps: Parse Arguments → Detect Active Modes
  • Stopping whichever autonomous mode is currently running
  • SKILL.md covers What It Does, Usage, Auto-Detection and Workflow, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

This skill reads a local state folder to work out which of several autonomous modes is currently running, then cancels it in a dependency-aware order: OMG Autopilot first (including any linked Ralph or UltraQA cleanup), then a standalone Ralph loop, Ultrawork, UltraQA, a running Team, and finally a Self-Improve loop. A force flag skips detection and clears every state file outright.

Depending on the mode, cancellation either preserves state for a later resume - OMG Autopilot keeps its phase, files and spec, and Self-Improve keeps its iteration count - or clears the state entirely, as with Ralph, Ultrawork and UltraQA, and a Team shutdown, which signals every teammate and waits up to 15 seconds per member for a response before cleaning up.

When your agent uses it

  • Stopping whichever autonomous mode is currently running
  • Shutting down a stuck multi-agent Team session
  • Clearing all autonomous mode state after something went wrong

Example prompts

  • “Cancel whatever autonomous mode is currently active.”
  • “Force-clear all OMG mode state, something's stuck.”
  • “Stop the Team session and shut down the teammates.”

Workflow steps

2 steps, taken from the step headings in SKILL.md.

  1. Parse Arguments
  2. Detect Active Modes

What it can do on your machine

Read from SKILL.md and the folder at commit b4f0d9d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

OMG Mode Canceller loads about 690 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 317 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~36
When it runs · the whole SKILL.md, loaded when a task matches
~690

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Cancel

Intelligent cancellation that detects and cancels the active OMG mode.

What It Does

Automatically detects which mode is active and cancels it:

  • OMG Autopilot: Stops workflow, preserves progress for resume
  • Ralph: Stops persistence loop
  • Ultrawork: Stops parallel execution
  • UltraQA: Stops QA cycling workflow
  • Team: Sends shutdown to all teammates, cleans up
  • Self-Improve: Stops loop, preserves iteration state for resume

Usage

/cancel
/cancel --force
/cancel --all

Auto-Detection

Reads .omc/state/ to discover which mode is active. Cancels in dependency order:

  1. OMG Autopilot (includes linked ralph/ultraqa cleanup)
  2. Ralph (cleans linked ultrawork)
  3. Ultrawork (standalone)
  4. UltraQA (standalone)
  5. Team (graceful shutdown + cleanup)
  6. Self-Improve (preserve iteration state)

Workflow

1. Parse Arguments

Check for --force or --all flags.

2. Detect Active Modes

Use omg_read_state to check each mode's state file.

3A. Force Mode (--force or --all)

Clear ALL state files in .omc/state/. Nuclear option.

3B. Smart Cancellation (default)
If OMG Autopilot Active
  1. Check for linked ralph → clear ultrawork if linked → clear ralph
  2. Check for linked ultraqa → clear it
  3. Mark omg-autopilot inactive (preserve state for resume)
If Ralph Active (not OMG Autopilot)
  1. Check for linked ultrawork → clear if linked
  2. Clear ralph state
If Team Active
  1. Signal shutdown to all teammates
  2. Wait for responses (15s timeout per member)
  3. Clean up team resources
  4. Clear linked ralph if present
If UltraQA / Ultrawork / Self-Improve Active

Clear state directly.

No Active Modes

Report: "No active OMG modes detected. Use --force to clear all state."

What Gets Preserved

ModeState PreservedResume Command
OMG AutopilotYes (phase, files, spec)/omg-autopilot
Self-ImproveYes (iteration state)/self-improve --resume
RalphNoN/A
OthersNoN/A

Messages

Questions about OMG Mode Canceller

What does OMG Mode Canceller do?

Detects which autonomous OMG mode is currently active - Autopilot, Ralph, Ultrawork, UltraQA, Team or Self-Improve - and shuts it down cleanly. This skill reads a local state folder to work out which of several autonomous modes is currently running, then cancels it in a dependency-aware order: OMG Autopilot first (including any linked Ralph or UltraQA cleanup), then a standalone Ralph loop, Ultrawork, UltraQA, a running Team, and finally a Self-Improve loop. A force flag skips detection and clears every state file outright.

When should I use OMG Mode Canceller?

OMG Mode Canceller fits situations like: stopping whichever autonomous mode is currently running; shutting down a stuck multi-agent Team session; clearing all autonomous mode state after something went wrong.

How do I install OMG Mode Canceller in Claude Code?

Run `npx skills add zereight/gitlab-mcp --skill cancel -a claude-code`. Or copy the skill folder (.github/skills/cancel in zereight/gitlab-mcp) into .claude/skills/cancel in your project. Claude Code loads it when a task matches its description.

How do I install OMG Mode Canceller in Codex?

Run `npx skills add zereight/gitlab-mcp --skill cancel -a codex`. Or copy the skill folder (.github/skills/cancel in zereight/gitlab-mcp) into .agents/skills/cancel in your project. Codex loads it when a task matches its description.

Can I use OMG Mode Canceller in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add zereight/gitlab-mcp --skill cancel -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cancel, .gemini/skills/cancel, .github/skills/cancel and .opencode/skills/cancel in your project.

What does OMG Mode Canceller need to run?

SKILL.md names no scripts, command-line tools or credentials: OMG Mode Canceller is instructions for the agent only.

Does OMG Mode Canceller access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is OMG Mode Canceller safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does OMG Mode Canceller use?

OMG Mode Canceller is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does OMG Mode Canceller use?

About 690 tokens (SKILL.md is roughly 2.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to OMG Mode Canceller?
