Almost all work still ran under ~/Desktop/AI-Workspace (98.4% of tokens, 35/40 sessions) even though the repo has moved to ~/AI-Workspace — worth confirming new terminals/sessions are actually opened in the new path, or the split-state migration risk this workspace's own CLAUDE.md warns about will keep compounding.
The "1" prompt that cost 31.8M tokens (152 calls) suggests a very long-running session got a one-character continuation instead of a fresh context — consider starting a new session (or /clear) after a big milestone rather than replying tersely into an already-large transcript.
Cache breaks cluster right at session-handoff prompts ("重新交接", "继续往下做吧") — if handoffs across terminals are routine, writing the continuation prompt to platform/prompts/ (as this workspace's CLAUDE.md already asks) before closing a session avoids re-priming a multi-hundred-k-token context cold.
