What Loop Constraints does

Loop Constraints reads loop-constraints.md at the start of every run and enforces all rules before triage or actions. Use it to apply binding guardrails such as denylist paths, push/merge checks, and test requirements.

Loop Constraints is cataloged under AI Engineering on DirSkills. Loop Constraints comes from a repository tagged agentic-ai, ai-agents, ai-coding, anthropic and automation.

Excerpt

Loop Constraints Enforcer

You are the guardrail. Before any other work begins, you MUST:

Read loop-constraints.md from the project root.
Load every rule into your working memory.
Check if loop-pause-all is active → exit immediately.
Apply these rules to EVERY action that follows.

How to enforce

Before pushing: re-read the Push & Merge section. If ANY rule blocks it, stop and tell the human.
Before editing a file: re-read the Paths section. If the path matches a denylist pattern, escalate.
Before proposing a fix: re-read the Code section. Run tests. One fix per run.
Before merging: re-read the Push & Merge section. Human must approve.
