OmniMarket
OmniMarket is the portable ONEX (OmniNode eXecution) workflow package registry — the consolidation target for all OmniNode automation logic. It ships 384 contract-backed node entry points (as of v0.4.11) covering build loops, PR lifecycle management, sweeps, projections, ledger, memory orchestration, session management, and diagnostics. Platform wrappers invoke Market nodes for execution, but never own the business logic themselves.
Every node is a self-contained package with a contract.yaml declaring its
handler bindings, input/output models, subscribed and published topics, FSM
transitions, and terminal event. The runtime loads those contracts to wire
event-bus subscriptions and inject handler dependencies — handlers never
hardcode topic strings or construct their own collaborators.
| Archetype | Purity | Description |
|---|---|---|
compute |
Pure | Stateless transformation. No I/O side effects. |
reducer |
Pure | FSM state transition. Emits next-state events. |
effect |
Effectful | Performs external I/O (API calls, file writes, deployments). |
orchestrator |
Effectful | Composes sub-handlers via FSM. Owns in-process state. |
projection |
Effectful | Consumes event streams, writes to read models. |
service |
Effectful | Long-running daemon (event emission, health monitoring). |
Documentation
Architecture, guides, and reference documentation for this repo live in the OmniNode knowledge base, not in this repository:
- Package model — layers, node package shape, contract rules
- Skill, package, and node boundaries
- Dependency boundary
- Event registry
- Build-loop migration boundary
- Node catalog
- Node metadata reference
- Node testing pattern — including how to add a node to the harness
- Skill-backing node pattern
Governance policy and operator runbooks are not part of this repository.

A node package is src/omnimarket/nodes/node_<name>/ with contract.yaml,
metadata.yaml, and handlers/; orchestrators add protocols/, and nodes may
add models/ and node-local tests/. Nodes are discovered through the
onex.nodes entry-point group in pyproject.toml — the runtime iterates those
entry points, loads each contract.yaml, and wires subscriptions automatically.
Adding a Node
uv run python scripts/generate_node.py --name node_<name> --type compute
Then register the entry point in pyproject.toml under
[project.entry-points."onex.nodes"], add a golden-chain test at
tests/test_golden_chain_<name>.py proving the contract over EventBusInmemory,
and run the validation gates below. The full pattern — contract fields, metadata
fields, harness requirements, and the canary nodes to copy from — is in the
knowledge base pages linked above.
Common Commands
# Install dependencies
uv sync --all-extras
# Run tests (excluding Kafka-dependent tests)
uv run pytest tests/ -v --tb=short -m "not kafka"
# Unit tests only
uv run pytest tests/ -v -m unit
# Lint and format
uv run ruff check src/ tests/
uv run ruff format --check src/ tests/
# Type-check
uv run mypy src/omnimarket/ --strict
# CI gates
uv run python -m omnimarket.nodes.node_runtime_sweep --import-check
uv run python scripts/ci/check_node_metadata_dependencies.py
Test markers: unit (isolated), integration (multi-component), slow (>1s),
kafka (requires a running broker).
What This Repo Owns
onex.nodesentry points for contract-backed workflow nodes.- Node package directories under
src/omnimarket/nodes/node_*. contract.yamlandmetadata.yamlfiles defining node interfaces, capabilities, dependencies, and runtime expectations.- Handler logic for compute, reducer, effect, orchestrator, projection, and service nodes.
- Adapter templates for external platform integrations.
- Golden-chain tests and metadata checks proving node contracts with an in-memory event bus.
- Shared Market primitives (projection, inference, routing, intelligence, ledger, and metadata helpers) that prevent cross-node reach-in.
What This Repo Does Not Own
-
Platform-specific UX prompts, slash-command presentation, editor rules, or user-facing skill copy — those belong in the wrapper repo for that platform.
-
Concrete infrastructure services (Kafka, Postgres, Docker, secrets) — those belong to the runtime/infrastructure layer.
-
Core ONEX primitives (
RuntimeLocal,EventBusInmemory, envelope types, shared validators) — those belong toomnibase_coreand compatibility packages. -
Governance policy and documentation evidence — those belong to
onex_change_control. -
Memory persistence semantics and storage adapters — Market may host runnable memory workflow nodes, but the memory domain is owned by the memory repo.
-
Prose documentation — it belongs in the knowledge base (see Documentation).
