Package taxonomy

Loop Engine installs in layers. The minimum floor is always @loop-engine/sdk. Additional packages are opt-in by capability.

Public docs group connections as Providers, Channels, and Integrations. npm package names and developer types (ActorAdapter, ToolAdapter, IntegrationAdapter archetypes) sit underneath — see IntegrationAdapter archetype.

By runtime role

| Runtime role | What you add | Required | Packages (current) | Planned | | --- | --- | --- | --- | --- | | Runtime core | Types, loop execution, guards, actors, events | always | sdk, runtime, core, loop-definition, guards, actors, events, signals | — | | Provider | Governed LLM actors and tool steps (intelligence) | one per model / use-case | adapter-anthropic, adapter-openai, adapter-gemini, adapter-grok, adapter-perplexity, adapter-vercel-ai | adapter-ollama, adapter-cohere, adapter-mistral | | Channel | Route PENDING_HUMAN_APPROVAL to human surfaces | when humans approve outside your app | adapter-openclaw | adapter-slack, adapter-teams, adapter-discord, adapter-webhook | | Integration | Persistence, event buses, operational backends | pick per environment | adapter-memory, adapter-postgres, adapter-kafka, adapter-http, adapter-pagerduty, adapter-commerce-gateway | adapter-redis, adapter-sqlite, adapter-dynamodb | | Platform & tooling | Catalog, metrics, devtools | optional | observability, ui-devtools, registry-client | adapter-datadog, adapter-grafana |

Minimum install

1npm install @loop-engine/sdk

Core primitives ship in @loop-engine/sdk. Standalone @loop-engine/* packages exist when you want explicit layer boundaries.

Common install recipes

Governed Claude tool calls (Provider + framework bridge)

1npm install @loop-engine/sdk @loop-engine/adapter-anthropic @loop-engine/adapter-vercel-ai

Human approval via messenger (Channel)

1npm install @loop-engine/sdk @loop-engine/adapter-openclaw @loop-engine/adapter-memory

Production loop with persistence + Provider + ops trigger (Integration + Provider)

1npm install @loop-engine/sdk @loop-engine/adapter-postgres @loop-engine/adapter-anthropic @loop-engine/adapter-pagerduty

Multi-model loop

1npm install @loop-engine/sdk @loop-engine/adapter-anthropic @loop-engine/adapter-openai @loop-engine/adapter-postgres

Observability stack

1npm install @loop-engine/sdk @loop-engine/observability @loop-engine/ui-devtools

Dependency direction

Runtime core has no Loop Engine upstream dependencies. Providers, Channels, and Integrations depend on core. Add one package per capability — not every row in the table.
