AI Council 裡的 Claude 成員明明被要求只討論，卻每回合還背著一整箱用不到的工具，會白佔你的 Claude 額度。先前在沒有附上專案資料夾時，claude -p 沒有傳入 --tools，Claude Code 仍會把 Bash、Edit、Write 等內建工具（讓 AI 能執行終端機、編輯與寫入檔案的能力）整套塞進每回合的輸入。現在此情況會明確傳入 --tools ""，把工具箱留在門外。每次 Claude 呼叫也會加上 --exclude-dynamic-system-prompt-sections，讓系統提示詞（AI 每回合先讀的固定規則）開頭在各回合維持位元組完全一致，較有機會命中 Anthropic 的自動提示詞快取（把已處理內容暫存直接沿用），少花重複額度。這只影響 Claude；Codex 和 Antigravity 成員不變。
In AI Council, Claude participants are told to discuss rather than use tools, yet they used to carry a whole unused toolbox into every turn, consuming Claude quota. When claude -p ran without an attached project folder, it omitted --tools, so Claude Code still packed its built-in tools—Bash, Edit, Write, and more—into each turn's input. It now explicitly sends --tools "" in that case, leaving the toolbox outside. Every Claude call also adds --exclude-dynamic-system-prompt-sections, keeping the system-prompt prefix byte-for-byte stable across turns and giving Anthropic's automatic prompt cache a better chance to reuse it. Codex and Antigravity participants are unchanged.
**AI Council spends less Claude quota per turn**: `claude -p` calls without an attached project folder used to omit `--tools` entirely, so Claude Code loaded its full built-in toolset — Bash, Edit, Write, and the rest — into every turn's input even though the council prompt already tells participants not to call tools. Calls now pass `--tools ""` when no project folder is attached, and every Claude call adds `--exclude-dynamic-system-prompt-sections` to keep the system prompt prefix byte-stable across turns for a better shot at Anthropic's automatic prompt caching. Codex and Antigravity participants are unaffected.
