AgentLint is an open-source repository linting, validation, and workflow enforcement harness developed by 0xmariowu. It is designed to enforce structural consistency, security hygiene, and verification gates across repositories utilizing AI agent workflows and automated pipelines. In day-to-day operations, AgentLint operates as both a command-line utility and an automated GitHub Action distributed via the GitHub Marketplace. It inspects repository configurations, branch protection templates, and test-pairing setups while integrating with agent configurations (such as Claude plugins) and isolated execution environments like E2B for testing agent scenarios. AgentLint differentiates itself from general-purpose linters by focusing on fail-closed automation gates for agentic development. Rather than allowing unconfigured branch protection or unasserted check contexts to silently pass, it strictly verifies check-run satisfaction, blocks template configuration drift, and enforces safe dependency execution defaults like --ignore-scripts. The tool is distributed under an open-source repository model on GitHub, providing tagged releases and GitHub Action integrations for automated CI/CD pipelines.
