cancel-loop

A command that stops an active automated work loop while keeping its completed and unfinished task information.

In plain words
What is it for?
Use it to cancel implementation, planning, task, or beads loops and then inspect the remaining task status.
Why use it?
It lets you end a loop safely when you need to pause or change direction without losing track of progress.

Getting it into your agent

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-loop 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 2d 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.

What it actually says

Cancel Loop

Gracefully stop any active loop while preserving progress.

Works with all loop commands: /implement-loop, /plan-loop, /tasks-loop, /beads-loop.

Note: Use /cancel-loop for loops, /cancel-swarm for swarms, and /cancel-team for Agent Teams.

Instructions

Check for any active loop state file and cancel it:

  1. Check for .claude/implement-loop.local.md
  2. Check for .claude/plan-loop.local.md
  3. Check for .claude/tasks-loop.local.md
  4. Check for .claude/beads-loop.local.md

For each found:

  • Read iteration info from the file
  • Remove the file
  • Report: "Cancelled [type] loop at iteration N"

If none found:

  • Say "No active loop found."

After Cancellation

Task progress is preserved:

  • Completed tasks remain completed
  • In-progress/pending tasks remain in their current state

To check task status:

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.
