RukSafe workspaces for coding agents

Create, prepare, assign, and reuse Git worktrees without sharing writable dependencies between agents.

Local by design

Ruk coordinates worktrees on one host. It needs no service, account, or long-running daemon.

One dependency-free Go runtime powers npm and standalone distributions, with native process inspection on Windows.

Every assignment receives an immutable ID, so delayed automation cannot release a workspace after reassignment.

Ruk fingerprints dependency inputs and prepares a local projection only when the workspace needs one.

ruk acquire agent/auth-flow --owner agent-17 --json
cd <returned-path>
ruk run -- bun test
ruk release <returned-assignmentId> --json

Keep both values returned by acquire: the absolute path tells the agent where to work, and the assignmentId authorizes renewal and release.

Exact IDs matter

Never infer an assignment ID from a branch or path. A new assignment receives a new fencing token even when Ruk reuses the same workspace.

The command is pronounced “rook.”
