loop-engineering

loop-engineering is a skill for Claude Code, Codex from alrece/loop-engineering. It costs 102 tokens per session (4,071 once invoked), scanned A, original, no licence file.

An automated engineering workflow that takes a project idea through planning and implementation over a long-running loop. It coordinates several development tools and chooses among options during the process, asking the user for verification at the end.

In plain words
What is it for?
Use it to propose an idea, create a rough plan, run the project automatically, and coordinate tools for specification writing and code review.
Why use it?
It reduces the need to manually coordinate each stage of a large engineering task. The workflow keeps the project moving through planning, execution, and review before requesting final confirmation.

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-engineering 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 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.
