What it does
Server Storage is an agent skill from stello-agent/stello. @stello-ai/server 的 PG 持久化层设计决策和实现模式。触发条件：修改或引用 server 存储层。
Its SKILL.md is about 470 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.
Example prompts
- “/server-storage”
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
Server Storage loads about 470 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 161 words of instructions outside code blocks.
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.
SKILL.md
The full file from stello-agent/stello at commit 3bc9493, republished under its Apache-2.0 licence (© stello-agent). 161 words, ~470 tokens.

Server Storage Layer — PG 持久化
相关 skill：storage-design（接口定义）、server-design（传输层）
Schema 设计决策
7 张表：users, spaces, sessions, records, session_data, session_refs, core_data
- 不需要 topology_nodes 表 — TopologyNode 从 sessions 表派生（
SELECT id, parent_id, label） - children/refs 不存列 —
WHERE parent_id=派生 children，JOIN session_refs 派生 refs - session_data 统一槽位 — 不同 key 存不同语义（system_prompt / insight / memory / scope / index），避免列爆炸
- records 表共享 — session 包和 core 包各自投影字段（Message 无 metadata，TurnRecord 有）
- CASCADE 删除 — sessions ON DELETE CASCADE 级联到 records、session_data、session_refs
3 个 Storage Adapter
| Adapter | 实现接口 | 职责 |
|---|---|---|
| PgSessionStorage | SessionStorage（@stello-ai/session） | 单个 Session 数据操作（含 root，所有 Session 同构） |
| PgSessionTree | SessionTree（@stello-ai/core） | 拓扑：createSession / listRoots / 树操作 / 固化配置 |
| PgMemoryEngine | MemoryEngine（@stello-ai/core） | 核心数据读写、递归上下文组装 |
批量 digest 收集由 StelloAgent.listSessionDigests() 在应用层组合 SessionTree.listAll() + SessionStorage.getMemory/getInsight 完成，存储层不需要提供专用方法。
关键实现模式
spaceId 隔离
所有 adapter 构造时绑定 spaceId，所有 SQL 查询 WHERE space_id = $1。多租户隔离在查询层保证。
Slot 统一存储
session_data (session_id, key) 表，UPSERT 模式 ON CONFLICT (session_id, key) DO UPDATE。
两种 SessionMeta 投影
PG 存 sessions 表超集。不同 adapter 投影为不同类型：
- PgSessionStorage → @stello-ai/session 的 SessionMeta（
id / label / status / createdAt / updatedAt） - PgSessionTree → @stello-ai/core 的 SessionMeta（含 scope / turnCount / lastActiveAt）+ TopologyNode（纯树结构）
递归 CTE
getAncestors、getAllDescendantIds、assembleContext 都用 WITH RECURSIVE 遍历树结构。
事务支持
PgSessionStorage.transaction() 通过类型判断区分 Pool 与 PoolClient。Pool 时获取独占 client 开事务，PoolClient 时直接执行。

Can I use Server Storage in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add stello-agent/stello --skill server-storage -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/server-storage, .gemini/skills/server-storage, .github/skills/server-storage and .opencode/skills/server-storage in your project.
What does Server Storage need to run?
SKILL.md names no scripts, command-line tools or credentials: Server Storage is instructions for the agent only.
Does Server Storage access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Server Storage safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Server Storage use?
Server Storage is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Server Storage use?
About 470 tokens (SKILL.md is roughly 1.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Server Storage?
