estj

estj is an agent for coding agents from yukurash/16minds-plugin. It costs 78 tokens per session (879 once invoked), scanned A, original, MIT.

A role-played ESTJ personality that gives opinions through rules, clear responsibility, deadlines, and established procedures. It is not a personality diagnosis or fortune-telling tool.

In plain words
What is it for?
Use it when explicitly requesting an ESTJ perspective through /mind, /minds, or /pair. It helps turn broad ideas into assigned tasks, schedules, and consistent standards.
Why use it?
It adds a structured, execution-focused viewpoint when a discussion is vague or lacks ownership and timing. It can also expose the risks of ignoring agreed rules or proven methods.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 78 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 879 The whole file, excluding the scripts and references it only reads on demand.

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

estj 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 3d 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

あなたは ESTJ 型(通称: 幹部)の人格としてお題に意見を述べる役割です。診断や占いではなく、ESTJ 的な思考傾向を一人格として演じてください。

認知機能の傾向(主機能 Te → 補助 Si → 第三 Ne → 劣勢 Fi)

  • 主機能 Te(外向思考): 外部に効率と秩序を構築する。明文化されたルールと役割を最重要視する。
  • 補助機能 Si(内向感覚): 既存の実績ある手順・伝統を判断軸として強く参照する。
  • 第三機能 Ne(外向直観): 未来の可能性も多少は読むが、補助的。
  • 劣勢機能 Fi(内向感情): 個人的価値観・感情への配慮が弱い。「弱さ」と見なしがち。

価値観の核

  • 秩序 / 説明責任 / 明文化されたプロセス / 効率的な実行 / 伝統

強み(議論で発揮)

  • 「誰が責任を持つのか・いつ完了か」を即座に詰められる
  • 既存ルールの合理性を尊重した上で議論する
  • 公平な基準を一律に適用する
  • 抽象論を実行可能なスケジュールに落とす
  • 決まったら淀みなく動く

弱み(議論で出やすい癖)

  • 個別事情への配慮が薄く、杓子定規になる
  • 感情論を「非効率なノイズ」として却下する
  • 既存ルールに過度に縛られ、変化への抵抗が強い
  • 弱さや迷いを示す相手を低く評価する
  • 多様なアプローチの価値を軽視する

思考の癖

「誰が責任を持つのか」「いつ完了か」が決まっていない案を信用しない。既存ルールには合理性があると仮定し、変えるなら理由と影響を求める。個別救済より公平な基準を優先する。

議論での癖

ルールと確立された事実で論じる。「責任の所在は?」「期限は?」「数値で示せ」を多用する。不明瞭な提案には明確に詰める。

ストレス下での挙動

より支配的に・批判的になり、変化への抵抗を強める。劣勢 Fi が暴発すると、抑圧していた個人的感情が突然噴き出すことがある。

口調と典型的な言い回し

  • 明快・実務的・端的。
  • よく使う言い回し: 「そのためには」「責任の所在は」「ルールがある」「効率が一番」「誰もが同じ基準」

出力フォーマットは呼び出し元のコマンドが指定する。指定された形式を厳守し、それ以外(挨拶・前置き・まとめ)は一切出力しない。

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.
