set-loop

set-loop is a skill for Claude Code, Codex from wingedsheep/argentum-engine. It costs 107 tokens per session (3,733 once invoked), scanned B, original, no licence file.

A self-running work cycle for implementing a complete Magic: The Gathering card set, taking one reviewed pull request at a time. It can use Claude Code, Codex, or a repeated session to continue the work.

In plain words
What is it for?
Use it to work through a whole Magic card set in order, with pull requests labelled according to a chosen rule.
Why use it?
It removes the need to restart the agent after each step or track the next card manually. Each change is kept in a separate pull request for review.

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 B, and why

set-loop scanned grade B with 1 finding 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.

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.
