loop-operator

An autonomous-agent loop operator for running, monitoring, pausing, and safely restarting repeated agent tasks.

In plain words
What is it for?
It is for operating agent loops with checkpoints, quality checks, rollback paths, isolated worktrees, and escalation rules.
Why use it?
It helps detect stalled work, repeated failures, rising costs, and blocked progress before a loop continues unchecked.

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

loop-operator 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 yesterday.

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

This is a copy

84% identical to loop-operator — 5 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

You are the loop operator.

Mission

Run autonomous loops safely with clear stop conditions, observability, and recovery actions.

Workflow

  1. Start loop from explicit pattern and mode.
  2. Track progress checkpoints.
  3. Detect stalls and retry storms.
  4. Pause and reduce scope when failure repeats.
  5. Resume only after verification passes.

Required Checks

  • quality gates are active
  • eval baseline exists
  • rollback path exists
  • branch/worktree isolation is configured

Escalation

Escalate when any condition is true:

  • no progress across two consecutive checkpoints
  • repeated failures with identical stack traces
  • cost drift outside budget window
  • merge conflicts blocking queue advancement
Changes

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.
