Agent Guardrail Library

Turn your coding agent's repeated mistakes into installable, reusable guards

Problem

Coding agents repeat the same classes of mistakes in a project: breaking config, forgetting migrations, using the wrong command, leaving cleanup for you. Some developers have stabilized their workflow only by writing down their own agent's repeated failures as guards, but that knowledge sits in personal repos and cannot be reused.

Solution

A guardrail registry and manager that packages "common agent mistake → guard rule / check script" into installable entries grouped by language, framework and toolchain; one command wires them into an agent's hooks to block risky actions and suggest fixes; trigger stats show which rules actually help.

Users

Individual developers and small teams using coding agents, and people maintaining agent workflow templates

MVP

Rule-pack format plus CLI install/uninstall; 20 starter rules covering migrations, dependencies and dangerous commands; hooks integration for one agent; trigger logs; skip auto-generated rules and enterprise policy engines

Revenue

Free base rule library plus paid curated packs and team sync subscription; revenue share to incentivize community contributors.

Why now

Coding agents are now part of daily development and their failure modes have become stable enough to codify; agent hook mechanisms just opened up, so whoever builds the reusable rule library first captures the ecosystem.
