03-construction-jev

03-construction-jev is a skill for Claude Code, Codex from miyatti777/ai-plc. It costs 50 tokens per session (283 once invoked), scanned A, original, MIT.

An experimental construction workflow that follows an existing AI-PLC build process and changes its follow-up commands to use Jev variants. It also supports optional conversation monitoring through a configured hook.

In plain words
What is it for?
Continuing an AI-PLC project from inception into construction when the project uses the Jev experimental workflow.
Why use it?
It keeps the experimental monitoring setup separate from the core workflow. The input does not describe the underlying construction process in detail.

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

03-construction-jev 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 16d 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 it actually says

AI-PLC Stage 3: Construction(Jev実験版)

🧪 実験版(ai-plc-jev 1.12.0-exp.2): 手順は本体 .claude/skills/ai-plc/03-construction/SKILL.md をそのまま読んで実行する。本ファイルは差分だけを定義する。呼ぶ条件は本体と同じ(RUL_plc_adaptive §6。Agent 定義が要るときだけ)。Constructionに Jev の判定は入れない(Agent定義の項目有無はコードで、中身は Stage 4 の独立reviewerで見るため)。

本体との差分

  1. Next Action のコピペ用プロンプト: /04-operation-jev 形式で書く
  2. 会話監視(凍結中): 会話監視 hook は新しく登録しない。登録している場合は外してかまわない

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.
