# /athena-checkpoint — 会话记忆固化 (v9.9.6)

Memory contract: **Tier1 working memory** only supplies the current-turn delta; **Tier2 persistent memory** receives authoritative state; **_index.md retrieval router** keeps stage/next_action/current sprint, authoritative pointers, route_history≤10 and current-state log≤10. Detailed history belongs in `session-log.md`; hooks are fallback only.

## 痛点 (你的反馈)

每次会话要结束, 你都得手动描述一堆 "现在做到哪、下次接着干啥", 让 Athena 存进 .ai_state.
本 skill 把这个动作做成一键: **agent 自己回顾本会话、提炼增量、落进工程**, 你只需确认。

## 触发

- **手动**: 用户说 `/athena-checkpoint` / "存一下进展" / "记录到 ai_state" / "收尾"
- **建议时机** (主 agent 可主动提醒, 但不自动执行): 会话结束前 · 长任务阶段切换 · 重要决策后 · context 快满时

## 不做

- ❌ 不自动频繁 checkpoint (token 浪费; 手动或建议, 不强制)
- ❌ 不替代 compact hook (hook 是兜底保险)
- ❌ 不写 compound (那是跨 sprint 沉淀; checkpoint 是本会话状态)
- ❌ 不总结整个项目史 (只本会话增量; 项目史看 git log + sprints/)
