Overview

ScaiFlow is a visual designer that compiles flowcharts into deployable ScaiCore agents.

You draw a graph of nodes — entry points, LLM blocks, tool calls, decisions, loops, human-in-the-loop reviews, sandboxed compute steps — and ScaiFlow emits the YAML (or SCIR binary) that ScaiGrid accepts to create and run a Core. The output is a portable, self-contained runtime; ScaiFlow itself is a design-time tool with no runtime dependency on the produced agent.

Who it's for#

• Product builders who want a no-code path to assemble agents that solve a specific business problem (intent classification, expense approval, customer support triage, RAG-based Q&A).
• Engineers who'd rather author flows visually and let the compiler keep them in sync with the underlying ScaiCore language than write the code by hand.
• Platform teams integrating ScaiFlow into a tenant — managing access via ScaiKey groups, provisioning ScaiGrid credentials, monitoring deploys.

What you can do#

• Draw flows that combine deterministic logic (@rigid), constrained LLM calls (@guarded), and goal-driven LLM reasoning (@flexible) — the three-tier "rigidity spectrum".
• Put humans in the loop at any decision point via @checkpoint blocks backed by ScaiQueue review surfaces.
• Run sandboxed code in ScaiBunker compute environments — provision, exec, file upload/download, destroy.
• Compose flows from sub-flows via core-to-core calls.
• Publish a flow as a chat model that any OpenAI-compatible client can reach at /v1/chat/completions.
• Manage a per-tenant catalog of published flow packages (.scaipkg) — install, version, share.
• Watch live executions, set runtime breakpoints, replay invocations from captured inputs.

What ScaiFlow is not#

• Not a runtime. The compiled YAML/SCIR runs on ScaiGrid; ScaiFlow doesn't intercept invocations.
• Not a low-code app builder. The output is an agent (asynchronous, event-driven, LLM-powered), not a CRUD frontend.
• Not a code transpiler of last resort. Every node maps to a real ScaiCore construct — if a feature isn't in ScaiCore yet, ScaiFlow doesn't pretend it is.

• Concepts — the mental model behind flows, nodes, rigidity, and compilation targets.
• Tutorials — end-to-end recipes for common patterns (HITL, RAG, multi-model).
• Reference — CLI, REST API, flow schema, every node kind, every configuration knob.
• Troubleshooting — common symptoms with diagnoses.
