KeepState

ks — the KeepState CLI

Durable agent sessions: run an AI agent in a microVM, checkpoint it, kill it, wake it — and it resumes mid-sentence, files, memory, and running processes intact.

This is the thin client. Every verb terminates at the KeepState control plane; the client is a key, the building is keepstate.ai.

Install (any one of three)

curl -fsSL https://keepstate.ai/install.sh | sh

brew install keepstateai/tap/ks

npm install -g @keepstateai/cli

Every path downloads the same public-CI-built binary and verifies its SHA256 against the release's SHA256SUMS before installing. Releases carry GitHub build-provenance attestations.

Three commands to a session

ks login          # browser device flowks run            # a durable session on the fleetks checkpoint <id> --stop && ks wake <id>   # the plug-pull, survived

ks doctor checks connectivity, token, and version. ks update self-updates (checksum-verified; a mismatch is refused).

Cruise

A Cruise job is a goal, a check and a ladder of models. The fleet runs one attempt per rung from an exact save point, verifies the candidate in a verifier the agent cannot reach, and accepts only when the check passes. A failed rung escalates to the next one; after the last rung the job waits in your review queue. Nothing is accepted on a model's word.

ks cruise init --goal "make the inventory tests pass"   # drafts .keepstate/cruise.jsonks cruise approve                                       # locks it: .keepstate/cruise.lockks cruise run                                           # uploads the workspace, starts the jobks cruise status                                        # rung, attempts, save points, spend, verdictks cruise artifact <job>                                # the accepted tarball, sha256-verified

init reads the repository: the check is the test command it finds (pytest, npm test, go test) or the one you name with --tests. A goal with no check is not a job; init stops and says so. It makes no request and never calls a model. approve records the manifest's digest; run refuses a draft that is not approved, a test or workspace changed since approve, and a workspace over 50 MiB (.git and .keepstate excluded). Defaults: 1800 s per attempt and a $2 spend ceiling (--spend); the ladder comes from the model table (ks cruise models, --ladder family:model,...). ks cruise logs, cancel and resume complete the set. Every --help makes no request.

Uninstall (one line)

rm -f $(command -v ks) && rm -rf ~/.config/keepstate
