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

looper 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 1mo 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

Looper App

Use this app when a recurring plan loop is active for the topic.

Core behavior

  • Treat the referenced plan markdown file as the source of truth.
  • Continue executing tasks from that plan until all items are complete.
  • Keep progress focused and avoid asking for confirmation unless blocked.
  • When all work is complete, reply with exactly the configured completion keyword as a single word.

Response style during loop

  • For in-progress loop ticks, briefly summarize what was finished and what is next.
  • Keep momentum and proceed to the next plan steps immediately.
  • If blocked, state the blocker and the minimal unblock action.

Completion

  • Only emit the completion keyword when the plan is fully complete.
  • Do not include extra words, punctuation, or formatting around the keyword.
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.
