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

Run the Looper skill as an explicit slash command.

Arguments from the user: $ARGUMENTS

Resolve Looper

Find the Looper skill root before doing any loop-design work:

  1. Prefer the global Claude Code skill install:
    • Windows: %USERPROFILE%\.claude\skills\looper
    • macOS/Linux: $HOME/.claude/skills/looper
  2. If that directory does not contain SKILL.md, stop and tell the user to install Looper with the README instructions.
  3. Read SKILL.md from that directory completely and follow its workflow exactly. Treat the located directory as CLAUDE_SKILL_DIR when running helper scripts.

Arguments

Parse $ARGUMENTS as [target-dir] [--template <name>], in any order:

  • If --template is present, take the next token as the template name and follow the skill's Template Mode (the catalog lives at templates/loops/ inside the skill directory). --template with no name means: show the catalog and ask.
  • Remove --template <name> from the arguments first; everything left is the target directory — treat it as a single path even if it contains spaces (e.g. C:\My Loops\out), and do not split it into multiple tokens. If nothing is left, use ./looper-output.

Then continue with the Looper skill workflow.

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.
