loop-engineering

An autonomous engineering workflow for coding agents that turns an idea into a plan and then runs the project through quality checks.

In plain words
What is it for?
It is for proposing software ideas, planning implementation, executing the work, and checking the result. The description notes that some interactive features are unavailable.
Why use it?
It coordinates several development methods and adds adversarial checks for long-running engineering work.

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 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 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.

loop-engineering is a skill published in the GitHub repository alrece/loop-engineering (2 stars, last pushed 1mo ago), with no licence file. It adds 95 tokens to every session and 8,355 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
