02-inception-jev

02-inception-jev is a skill for Claude Code, Codex from miyatti777/ai-plc. It costs 62 tokens per session (661 once invoked), scanned A, original, MIT.

An experimental planning workflow for breaking larger work into approved tasks. It adds a Jev check that compares the proposed task breakdown with stated success conditions.

In plain words
What is it for?
Planning and reviewing task decomposition when a project enables Jev monitoring and records whether its suggestions were accepted or rejected.
Why use it?
It can reveal success conditions that the breakdown may not cover before work begins. The result is only a hint and requires a human decision.

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

02-inception-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 2: Inception(Jev実験版)

🧪 実験版(ai-plc-jev 1.12.0-exp.2): 手順は本体 .claude/skills/ai-plc/02-inception/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。

本体との差分

  1. (凍結中・実行しない)成功条件カバー判定: 1.12.0-exp.2 から凍結中。jev_coverage_check.py は呼ばない(jev_monitor: true でも)
  2. (凍結中)カバー判定の記録: 1 を呼ばないので記録もしない。過去のカバー判定の未確認分は 5 で回収できる
  3. Next Action のコピペ用プロンプト: construction.required で /03-construction-jev または /04-operation-jev を選んで書く(Re-Inception後も同じ)。Phase 6 の「自動で進めるなら」の /goal 1行も、開始列を -jev 版のコマンドにする(pipeline_variant: jev)
  4. 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
  5. 未確認の判定の回収(jev_monitor: true の Layer だけ): 承認・完了報告の進捗表示に python3 .claude/ai-plc-jev/scripts/jev_bt_monitor.py --pending --layer <Layer> の件数を「🧭 未確認の Jev 判定: N件」として出し(0件なら 0件と出す)、Next Action のコピペ用プロンプトはすべての選択肢にその出力の「貼り付け用」1行を含める(記憶で書かない。0件なら書かない)。利用者の返答に「Jev判定 X・Y は accept」「全部accept」等があれば、示した貼り付け用1行の ID だけを --only に渡して --override-pending accept|reject --layer <Layer> --only X・Y [--except <ID> ...] で記録する(示した後にできた判定は記録しない)。記録はタスクの実行より先に行う

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.
