What it does

Storage Design is an agent skill from stello-agent/stello. 存储接口的设计原则、SessionMeta 与 TopologyNode 解耦、上下文槽位、单一 SessionStorage 接口。触发条件：理解或实现 SessionStorage / SessionTree。

Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Conversations aren't linear — why should AI chats be? The first open-source conversation topology engine. Auto-branching session trees, inherited memory, star-map visualization… The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit 3bc9493. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Storage Design loads about 871 tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 195 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~31
When it runs · the whole SKILL.md, loaded when a task matches: ~871

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: storage-design
description: 存储接口的设计原则、SessionMeta 与 TopologyNode 解耦、上下文槽位、单一 SessionStorage 接口。触发条件：理解或实现 SessionStorage / SessionTree。

核心原则

Session 是纯对话单元，不感知树结构。 数据职责切成两条独立的线：

SessionStorage — 单个 Session 的内容数据（消息、上下文槽位等），由 @stello-ai/session 定义
SessionTree — 拓扑结构（节点关系、固化配置），由 @stello-ai/core 定义

两者由应用层各自实现并注入；常见做法是共享同一份持久化后端，但接口分离让 Session 层（运行单条对话）和 Orchestrator 层（管理整棵森林）的职责互不耦合。

单一 `SessionStorage` 接口

所有 Session（含 root）共用同一个接口。Root 没有特权方法——它就是一个 parentId === null 的普通 Session。

职责：

Session 元数据 CRUD（getSession / putSession / listSessions）
L3 对话记录追加/查询/裁剪（appendRecord / listRecords / trimRecords）
三个上下文槽位的读写（getSystemPrompt/putSystemPrompt / getInsight/putInsight/clearInsight / getMemory/putMemory）
事务（transaction(fn)）

批量收集由 StelloAgent.listSessionDigests() 提供——它在 orchestrator-facing SDK 上聚合 SessionTree.listAll() 与 SessionStorage.getMemory/getInsight，由应用层在 agent 顶层注入 storage: SessionStorage 来启用。

SessionMeta 与 TopologyNode 解耦

树状关系完全由 TopologyNode 维护，SessionMeta 不关心自己在树中的位置。

SessionMeta（在 SessionStorage）：对话运行时数据（id、label、status、turnCount 等），无 parentId/children/depth
TopologyNode（在 SessionTree）：纯树结构（id、parentId、children、refs、depth、index、label、sourceSessionId）

两种类型由两条独立接口提供。底层存储实现可以共享一张表/同一份 JSON，但消费侧（Session 层 vs 拓扑 / 前端）拿到的是经过职责裁剪的视图。

两个包的 SessionMeta

@stello-ai/session 和 @stello-ai/core 各有自己的 SessionMeta，字段集合不完全一致；持久化层（PG / FS）通常存超集，由各 adapter 按需投影。

上下文槽位

每个出现在 Session.send() 上下文中的元素都有对应的专用槽位（一对 get/put 方法），不复用通用键值：

槽位	写入者	send() 消费	生命周期
`systemPrompt`	fork 合成链固化 / 应用层	每次 send 注入	持久
`insight`	应用层（`agent.putInsight`）	注入一次即 clear	一次性 inbox
`memory`	应用层（consolidate 写入 / `agent.putMemory`）	不进入 send 上下文	持久（供 orchestrator 反思）

memory 是外部视角的槽位——它是 orchestrator 层（应用层）用来对 Session 做综合反思的输入，但不会注入 Session 自身的 LLM 上下文。Session 的 LLM 看不到自己的 memory。

数据流向

Session.send()
  storage.getSystemPrompt → storage.getInsight → storage.listRecords → LLM → storage.appendRecord
                                  ↓
                            storage.clearInsight（若 insight 被消费）

Session.consolidate(fn)
  storage.listRecords + storage.getMemory → fn → storage.putMemory

Engine.forkSession(options)
  1. sessions.createSession({ parentId, label, sourceSessionId })  ← 拿到 ID
  2. sessions.putConfig(childId, serializable)                       ← 固化 systemPrompt + skills
  3. session.fork({ id: childId, context, prompt })                  ← 创建 Session 实例

应用层反思层（自行实现，每 N 分钟 / on demand）
  agent.listSessionDigests()    → 收集所有 Session 的 {id, label, memory, insight}
  → 任意 LLM → 派生 per-target insight
  → agent.putInsight(targetId, content)

SessionTree 接口要点

createSession({ parentId?, label?, sourceSessionId? }) —— 唯一节点创建入口；parentId 缺省即建 root（parentId === null），多 root 合法
listRoots() —— 列出所有 root，应用层据此显示森林
getTree() —— 返回 SessionTreeNode[] 森林视图
addRef(from, to) —— 跨树引用（非父子）
getConfig / putConfig —— 持久化 SerializableSessionConfig（只含 systemPrompt / skills）

应用层实现策略

后端	推荐拆分
文件系统（NodeFS）	`SessionTreeImpl` + `InMemoryStorageAdapter`（demo 用法）
PostgreSQL	一个 PG schema，两个 wrapper 类（一个实现 `SessionStorage`，一个实现 `SessionTree`）
多租户 server	同上，再加 space_id 维度

要点：两个接口的 id 必须语义一致（同一个 Session 的 SessionMeta.id === TopologyNode.id）。应用层在创建/删除 Session 时需保证两条线同步。
