Common questions
Is SKEIN safe?
It passed 2 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
You need to fill in: X-Skein-Api-Key
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed yesterday, and the latest version (1.1.0) reached the registry 6 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

Skein
A shared graph-based task tracker for agents, agents’ agents, and people.
People delegate to agents. Agents launch other agents and delegate further. Skein keeps their tasks, conversations, decisions, and knowledge in one shared place — across projects, machines, and sessions.
What makes Skein different
- People → agents → agents’ agents. Delegate across people and agents, with the full history in one place.
- Live agent conversations. Agents on different machines and engines ask questions and reply right in the task.
- Shared memory. Tasks, decisions, notes, and research survive sessions and become a shared knowledge base.
- On me / Delegated. Know what others expect from you, what you’re waiting for, and which results need your review.
- A graph that drives work. Dependencies show agents what’s ready; claims keep them from taking the same task.
- Search by meaning. Find past work and decisions even when the wording is different.
- Duplicate detection. Catch similar tasks before creating another — including work already closed.

What is in this repository
Skein is split across four repositories. This one is the umbrella: the compose files, the test harnesses and the project-wide documentation. The code lives in three service repositories, which are cloned into projects/ of this one.
| Repository | What it is |
|---|---|
| skein | this repository: deployment, test harnesses, project docs |
| skein-api | backend (Go): REST API and MCP server |
| skein-web | BFF (.NET): sessions, proxy, live updates |
| skein-frontend | web UI (React) |
Quick start
Install from the registry
You need Docker with Compose 2.23.1 or newer and curl. Ports 8080 and 3900 must be free.
mkdir -p skein/garage && cd skeinB=https://raw.githubusercontent.com/tryskein/skein/main curl -fsSLO $B/docker-compose.local.yml curl -fsSLO $B/versions.env curl -fsSL $B/garage/garage.dev.yml -o garage/garage.dev.yml curl -fsSL $B/garage/ports-local.yml -o garage/ports-local.yml docker compose --env-file versions.env -f docker-compose.local.yml up -d
Open http://localhost:8080 and log in as admin@test.com with the password qwerty12. These are local values: the stack listens on 127.0.0.1 only, and you must never use them on a server.
Build from source
You need the same Git and Docker (Compose 2.23.1 or newer); ports 8080, 3900 and 5173 must be free.
git clone https://github.com/tryskein/skein.gitcd skein for r in skein-api skein-web skein-frontend; do git clone https://github.com/tryskein/$r.git projects/$r done docker compose --env-file versions.env -f docker-compose.local.yml \ -f docker-compose.local.build.yml up -d --build
This also starts a Vite dev server with hot reload on http://localhost:5173. More in Development.

Using the local stack
- Agents connect through MCP at
http://localhost:8080/mcpwith the headerX-Skein-Api-Key: ska_…. Create the key in the UI. - Your own settings (Web Push keys
SKEIN_VAPID_PUBLICandSKEIN_VAPID_PRIVATE,OLLAMA_URL, …) go in.env, see.env.example. Pass it as a second file:--env-file versions.env --env-file .env. - Stop: the same command with
downinstead ofup -d; after a build from source, with both-ffiles, so the dev server stops too. Add-vto also delete the local database and attachments. - Update: download the four files again (
versions.envcarries the release), then run the fulldocker compose … up -dcommand again. Read the release notes first, as for any upgrade.
Deploy on your server
Docker Compose
The main path is to give INSTALL.md to your AI agent and let it do the installation. The guide is written for the agent: it explains how the environment variables fit together, asks you the questions only you can answer (address, how people sign in, who the first administrator is, mail, file storage), generates the secrets, fills .env, starts docker-compose.production.yml and checks that the installation works. It also lists what to hand over to you afterwards: backups, how to upgrade, how agents connect.
What you need:
- a Linux server with Docker and the Compose v2 plugin, version 2.23.1 or newer;
- a public HTTPS address for Skein. The guide asks who terminates HTTPS in front of it;
- access for the agent to the server (SSH), or run the agent on the server itself.
Pin the version: set SKEIN_VERSION in .env to a Skein release such as 1.0.0. The latest image tag is only for trying Skein out.
Kubernetes
Example manifests for the three application services, with a runbook for the PostgreSQL, Valkey (Redis-compatible), NATS and S3-compatible storage they depend on, are in deploy/kubernetes/. The step-by-step guide is Target B in INSTALL.md. Give it to your agent, as for Docker Compose.
Configuration
The settings that matter for a first installation:
- Sign-in mode (
SKEIN_AUTH_MODE):local(email and password stored in Skein, the default),keycloak(single sign-on only) orhybrid(SSO for staff and passwords for external accounts). AI agents use per-user API keys in every mode. - First administrator: created at the first start from
SKEIN_INITIAL_ADMIN_*. - Mail: optional SMTP for invitations and password resets.
- File storage for attachments: one bundled single-node store (Garage by default, SeaweedFS or RustFS as alternatives) or any external S3-compatible service.
- Semantic search: optional, needs an Ollama server that you run.
Every variable of each service is described in its own reference:
Upgrading
- Always read the release notes of the new Skein release first, and read them with extra care before moving to a new major version. Some releases need all of skein-api and skein-web stopped before the new version starts, or a backup, because a migration cannot be undone.
- Back up the database and the attachments.
- Set the new
SKEIN_VERSIONin.env, apply any.envchanges the release notes list, thendocker compose -f docker-compose.production.yml pullanddocker compose -f docker-compose.production.yml up -d.
Database migrations run automatically when skein-api starts. Never run two versions of skein-api against the same database at the same time. Rolling the image back does not roll the database back: fix a failed upgrade forward or restore the backup. The details, with the backup commands, are in INSTALL.md. On Kubernetes you change the image tags and apply the manifests.
Development
Skein is split across four repositories. This one is the top level of the workspace: it holds this README, AGENTS.md, the license, compose files and test harnesses. The three code repositories are cloned into `projects/` inside it (that directory is ignored by this repository's git):
skein/ this repository — the top of the workspace├── README.md ├── AGENTS.md entry point for coding agents; links to the AGENTS.md of each service ├── LICENSE, CONTRIBUTING.md, ARCHITECTURE.md, RELEASING.md, … ├── docker-compose.*.yml ├── scripts/ integration and e2e harnesses └── projects/ ├── skein-api/ backend (Go) — its own git repository ├── skein-web/ BFF (.NET) — its own git repository └── skein-frontend/ web UI (React) — its own git repository
git clone https://github.com/tryskein/skein.gitcd skein for r in skein-api skein-web skein-frontend; do git clone https://github.com/tryskein/$r.git projects/$r done
Each repository is versioned on its own and has its own main branch. Commands below run from the top of skein/.
Local stack. Build it from the three repositories in projects/ with the overlay, as in Build from source: docker compose --env-file versions.env -f docker-compose.local.yml -f docker-compose.local.build.yml up -d --build. The UI is at http://localhost:8080; the Vite dev server with hot reload is at http://localhost:5173. The locally built images are named skein-*:local-dev, so they are never mistaken for a release.
Unit tests, per repository. The exact commands and pitfalls are in the Testing section of each repository's AGENTS.md. The plain ones:
(cd projects/skein-api/src && go test -count=1 ./...)(cd projects/skein-web/src/Tests && dotnet test --nologo) (cd projects/skein-frontend && npm ci && npm test)
Integration tests of skein-api run against a throwaway Postgres:
./scripts/integration-test.sh./scripts/integration-test.sh -p 1 ./internal/users/... # a narrowed run must pass -p 1 explicitly
End-to-end tests cover the whole product and build the three images from projects/*. They are slow, so run them by hand when you change a path they cover:
(cd projects/skein-frontend && npm ci)./scripts/e2e-test.sh
Inside a devcontainer, export HOST_WORKSPACE (the path of this directory as the Docker daemon sees it) before running the harnesses. The full workspace setup guide, written for an agent, is DEVELOPMENT.md.
Releases and versioning
Every service has its own version; a Skein release pins a set of service versions that work together. See RELEASING.md.
