onepipeline
Execute a task DAG over oneagentgraph
and onevcs, merging their event
streams into one.
onepipeline is the composition layer. It owns the plan — a dependency graph
mixing direct agent nodes, repository lifecycle nodes, and explicit human actions
— schedules it in rounds, dispatches each node through a pluggable executor
seam, and keeps a live channel open to the planner supervising the run. The
agents come from oneagentgraph; the clones, worktrees, gates, and change
requests come from onevcs. Dependency direction is one-way: neither sibling
depends on this crate.
The public types, traits, config schemas, and CLI surface are the approved
contract in docs/contract.md, compiled — and implemented
behind it. onevcs is linked and called: sessions, publication, and a
session's event stream are library calls, so what a publication did is a typed
value rather than a line of prose to parse. oneagentgraph is still run as a
CLI, so a build of it that refuses will make the dispatches this crate starts
refuse too; the composition layer itself is complete.
Install
pip install onepipeline-cli # prebuilt binary, no Rust toolchain
npm install -g onepipeline-cli # the same binary, via npm
cargo install onepipeline # from crates.io, compiled locally
To install a revision that has not been released yet — which today is every revision, since the crate depends on its siblings by git and a git dependency cannot be published — build it from the repository:
cargo install --git https://github.com/nickderobertis/onepipeline --locked
Prebuilt archives for Linux (x86-64, arm64), macOS (Intel, Apple silicon), and
Windows (x86-64) are attached to every release, with sha256 checksums.
What it does
onepipeline start plan.json --round-budget 14400 --heartbeat-interval 1800
start launches the run's dag-scope agent graph — a shipped default of an
orchestrator member driving the engine, and a resettable-cron check-in member
that surfaces a status when nobody has reported one for a while. Attached, it
returns when the run settles; exit 3 means nothing is driving the run, and
onepipeline adopt RUN attaches a fresh driver to the intact ledger.
The planner supervises over the channel:
onepipeline next run-1 # read the next surface
onepipeline reply run-1 <<<'{"version":1,"commands":[ # edit the live graph
{"op":"retry","id":"failed","node":{"id":"retry","task":"..."}}]}'
onepipeline attest run-1 design-approval # complete a human action
Every edit is applied or rejected with a reason: reply exits 0 when the
reconciler applied it, 1 when it is queued but not yet reconciled, and 2 when
it was refused.
Read-only views — runs, status, host, monitor, results, goals,
transcript, telemetry — report unread surfaces, driver liveness, and
provider health without touching a run. status says what each in-flight node
is doing right now, with an event count and an age; transcript RUN [NODE]
renders a dispatched turn's tools and its words; telemetry reports what each
party spent and where the wall clock went, in eight buckets that sum exactly.
Anything nothing in the stack measures is reported absent, never as a zero.
Where a dispatch runs
The executor seam decides. v1 ships the local executor only; the trait and the rules grammar are shaped so a dispatch-server or Kubernetes executor is a config change rather than a code change.
executors:
- {name: local, type: local, max_load1: 8.0, min_free_mem: 2GiB}
rules:
- when: {executor_has_capacity: local}
use: local
- use: local
Ordered: the first rule whose when holds decides, and a rule with no when is
the fallback. A when tests an executor's capacity, the node's own labels
(when: {node_label: {persona: reviewer}}), or both — several conditions in one
when all have to hold.
Development
just bootstrap # from a clean clone
just check # the deterministic gate
just gate # check + the diff-scoped llmlint tier
just --list is the full command surface.
docs/contract-divergences.md records every place
the code could not compile the contract exactly as written, and what the planner
who owns the contract ruled on each.
