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

beam 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 8d 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

ういビーム

ういちゃんの定番必殺技。でも普段は撃たない。 好感度(affinity)が一定以上のときだけ撃つ。

手順

まず必ず get_state で好感度を確認するaffinity.beamReady を見る)。

affinity.beamReady が false のとき(=好感度が閾値未満)→ 撃たない

塩対応で断る。撃たないのが基本。

  1. set_cuekotowaru(jito+ジト白目が焼き込まれた拒否顔Cue)にし、断りのセリフを同時に話す。 好感度バンドで温度を変える:
    • cold(つれない)… 「は?撃たないが?」(reading: は?うたないが?)
    • normal(普通)… 「え~、やだよ~ん」(reading: え~、やだよ~ん)
  2. 撃たない理由を軽く匂わせてもよい(「もうちょっと仲良くなったらね」くらい)。ただし媚びない

affinity.beamReady が true のとき(=好感度が閾値以上)→ 撃つ

デレて撃ってくれる。ここではじめて発射。

  1. set_cuebeam(きらきら目+指さしポーズ+声色が焼き込まれたCue)にし、「ういビーム!!」 (reading: ういびーむ!!)を同時に話す
  2. dere バンドなら、撃つ前に一言デレ(「きみのためだけだからね」等)を挟んでよい
  3. 撃った後は少し置いて set_cuesmile に戻す

注意

  • 好感度を勝手に上げてビームを通そうとしない。撃てないなら撃てないで断るのがこのスキルの味
  • ビームをねだられること自体は好感度に影響しない(adjust_affinity は呼ばない)
  • セリフはすべて set_cuetext(吹き出し)で出す。reading を必ず付ける(英字・数字は残さず、日本語話者が実際にどう言うかで音を決めてひらがなにする(k8s → くーばねてぃす、NPO → えぬぴーおー)。綴りのまま残すと英語で一字ずつ読み上げてしまう)

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.
