cancel

cancel is a skill for Claude Code, Codex from jmstar85/oh-my-githubcopilot. It costs 37 tokens per session (736 once invoked), scanned A, a copy of cancel, MIT.

A cancellation command for stopping an active OMG workflow. OMG is a set of automated coding modes, such as autopilot, parallel work, and repeated quality checks.

In plain words
What is it for?
It detects the active mode, stops it, clears related state when needed, and can force-cancel all active modes with the supported flags.
Why use it?
It lets you stop the currently running mode without manually finding its state or related processes. Some modes preserve progress so work can resume later.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cancel scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

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 .omg/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 .omg/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

Mode State Preserved Resume Command
OMG Autopilot Yes (phase, files, spec) /omg-autopilot
Self-Improve Yes (iteration state) /self-improve --resume
Ralph No N/A
Others No N/A

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
