aln-loop-designer

aln-loop-designer is a skill for Claude Code, Codex from fyzycyst/Agentic_Loop_Notation. It costs 77 tokens per session (777 once invoked), scanned A, original, CC-BY-4.0.

A toolkit for designing and checking step-by-step loops for AI agents. It can express those loops in Agentic Loop Notation, a format for describing agent behaviour, and export them for Claude Code or Codex.

In plain words
What is it for?
Use it to design, audit, repair, or export AI-agent workflows. It supports scoped task prompts, Codex goals, skills, hooks, automations, scheduled tasks, and reusable examples.
Why use it?
It helps turn vague descriptions of agent behaviour into a defined process that can be reviewed for safety and reused. It also keeps related prompts, goals, skills, hooks, and scheduled actions in one design.

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

aln-loop-designer 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 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.

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.
