Session behavior pack for automatic token-saving decisions. Use when handling large tool output, structured data for another model, repeated handoff/status context, long logs, or when the user asks to save tokens/context. Prefer this unified pack over remembering separate TOON or context commands.
Prefer CodeGraph for codebase discovery, architecture questions, caller/callee tracing, and impact analysis before broad file reads or grep.
Codex `$offduty` / handoff closeout entry. 下班、换机、fresh session 前，把当前会话自动折叠到 repo-local continuity；不要要求用户填写 task-id/scope/type。
Codex `$onduty` / fresh-session resume entry. 开工、换机、fresh session 时，从 repo-local continuity 恢复可执行上下文。
Create and maintain compact, durable handoff docs for Claude/Codex/Hive/cheap-model collaboration; supports bare offduty/onduty fresh-session continuity, execution handoff identity, current-owner safety, progress files, packet refs, and multi-session write rules.
Use when the user asks for xmem, cross-project memory, project truth index, prior similar work, domain/service/deploy/COS/copy-domain routing, preserving feature invariants, historical bug patterns, or compact agent context; first verify that an `xmem` CLI or source registry is available.
Quick-reference card for all caveman modes, skills, and commands. One-shot display, not a persistent mode. Trigger: /caveman-help, "caveman help", "what caveman commands", "how do I use caveman".
Ultra-compressed communication mode. Cuts token usage ~75% by speaking like caveman while keeping full technical accuracy. Supports intensity levels: lite (default), full, ultra, wenyan-lite, wenyan-full, wenyan-ultra. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman. Also auto-triggers when token efficiency is requested.
