loop-engineering

loop-engineering is a skill for Claude Code, Codex from aiconnai/agentshield. It costs 77 tokens per session (3,234 once invoked), scanned A, original, no licence file.

Guidance for designing and running autonomous agent loops: repeated workflows where an agent checks state, takes bounded actions, and records handoffs.

In plain words
What is it for?
Use it to build, audit, secure, or operate loop workflows involving tools such as Codex, Grok, or Claude Code, including explicit goals and STATE.md handoffs.
Why use it?
It helps structure these workflows with limits, verification, worktree isolation, sub-agents, and cost controls.

Skill for Claude CodeCodex

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./target/release/agentshield wrap --policy agentshield.egress.toml -- <loop-command>.

Good fit Use it to build, audit, secure, or operate loop workflows involving tools such as Codex, Grok, or Claude Code, including explicit goals and STATE.md handoffs.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
