> **TL;DR.** Step enforcement is a guardrail mechanism for agentic LLM workflows that detects and corrects a model's failure to execute required steps in the prescribed sequence.

## Definition

Step enforcement is a guardrail mechanism for agentic LLM workflows that detects and corrects a model's failure to execute required steps in the prescribed sequence. It sits inside the agent loop, monitoring the model's tool-call trace against a declared prerequisite graph and firing a corrective nudge when a step is skipped.

The term was named and operationalized in [Forge](https://github.com/antoinezambelli/forge), an open-source reliability layer by Antoine Zambelli (Texas Instruments) published in February 2026. Forge's peer-reviewed paper — accepted to ACM CAIS '26, presenting May 26-29 in San Jose — evaluated 97 model/backend configurations and found step enforcement most significant for models with weaker sequencing discipline.

## Analogy

Think of it as a workflow linter that runs at execution time, not at code review.

## Why it's emerging now

Multi-step accuracy compounds: 90% per-step reliability yields only 59% success over five steps. Forge's Show HN on May 19, 2026 (613 HN points) demonstrated a five-layer guardrail stack — including step enforcement — closing that gap for 8B local models, days before its ACM CAIS '26 paper presentation.
