AI Workflow Standard

Define. Govern.
Execute. Observe.

A standard, three native SDKs, and Praxis—the AIWS workflow engine—for building governed, observable AI workflows across agents, tools, humans, and systems.

The complete stack

One system. Three layers.

Shared semantics connect what you define, what developers build, and what the runtime executes.

The Standard

Interoperable contracts, workflow semantics, governance rules, and an evidence model.

Read the Standard 02

The SDKs

Native TypeScript, Python, and Rust APIs built from the same closed wire records.

Praxis

The AIWS workflow engine: durable orchestration, recovery, scheduling, handoffs, controls, and operator evidence.

Understand Praxis

Governed execution

From intent to evidence.

Every stage has a defined shape, authority boundary, and durable record.

Human authority

Agents work.
Humans remain in control.

Approval gates, permissions, intervention, recovery, and uncertainty handling are part of the workflow—not exceptions bolted on afterward.

Native SDKs

Use the language you already work in.

Three independent libraries implement the same finite-v1 profile and share exact conformance scenarios.

# Install the native TypeScript SDK
npm install ./aiws-sdk-0.3.0.tgz

# Run the verified first workflow
node examples/guide/typescript/first-run.ts

# Install the native Python SDK
python -m pip install ./aiws_sdk-0.3.0-py3-none-any.whl

# Run the verified first workflow
python examples/guide/python/first-run.py

# Build the native Rust SDK
cargo build --locked

# Run the verified first workflow
cargo run --manifest-path examples/guide/rust/Cargo.toml --bin first-run

Why a standard?

AI workflows need a common language.

Agents, orchestrators, tools, and runtimes describe work differently. That makes governance, portability, recovery, and trustworthy evidence harder than they need to be.

AIWS defines shared semantics for how AI-powered work is described, executed, controlled, resumed, verified, and recorded.

Interoperable

Workflows do not belong to one model, agent, vendor, or runtime.

Durable

Execution survives pauses, retries, failures, and long-running work.

Human-centered

People can inspect, approve, intervene, and retain authority.

Observable

Every run produces structured state, events, evidence, and history.

Governed

Permissions and policies constrain what agents are allowed to do.

Verifiable

Acceptance conditions and evidence—not a completion claim—close the work.

Start building

Build workflows agents
can be trusted to run.
