Architecture artifact

Agentic Workflow Runner Architecture

A concrete AI systems design artifact for running LLM-assisted workflows through explicit task state, approval gates, tool permissions, retries, audit events, recovery paths, and human-operable controls.

Problem

Why This Artifact Exists

The artifact turns the AI direction into a concrete system design that can be implemented, tested, and evaluated.

Workflow Reliability

LLM workflows often fail as production software because generated actions are treated as one-shot responses instead of stateful operations with ownership, approval, retry, failure handling, and auditability.

Architecture

System Boundaries

The runner is designed around durable state, approval gates, explicit permissions, execution workers, audit trails, and recovery behavior.

01

Task records store

Task records store objective, status, actor, scope, model context, permissions, created time, and last transition.

02

Workflow states separate

Workflow states separate draft, planned, awaiting approval, executing, failed, recovered, completed, and cancelled paths.

03

Tool permissions define

Tool permissions define which actions can run automatically and which require explicit human approval.

04

Audit events record

Audit events record prompts, decisions, approvals, tool calls, retries, failures, and recovery actions.

05

Recovery logic allows

Recovery logic allows failed tasks to resume from known state instead of restarting with hidden context.

Modules

Implementation Modules

Each module owns one part of the workflow so AI behavior remains observable, controllable, and maintainable.

Data Flow

How The Workflow Moves

The most important part of the design is state movement, not model invocation.

Evidence

Why It Fits The Portfolio

This artifact is grounded in existing systems and writing rather than being presented as a finished AI product.

The artifact is connected to current writing on agentic workflow architecture and AI workload observability.

The design reuses existing portfolio themes: workflow recovery, audit visibility, permission boundaries, background jobs, and observable system state.

It creates a concrete implementation target for future AI-assisted infrastructure and developer-productivity experiments.
