+title: Plugin Submission & Security Audit Workflow
+slug: /contributors/plugin-submission-audit
+---
+
+## Goal
+
+Provide a repeatable workflow where community authors submit plugins through a Git repository URL, then pass an automated security/quality audit before publication in the wiki and release channels.
+
+## Submission Model
+
+1. Author opens a **Plugin Submission** issue.
+2. Author provides a public Git repository URL (`https://...git`).
+3. Maintainer triggers the security-audit workflow.
+
+## Automated Audit Steps
+
+- Clone submitted repository in CI.
+- Run static scan for suspicious calls and execution vectors.
+- Run secret and credential pattern checks.
+- Produce an auditable report artifact.
+
+## Release Gate Policy
+
+- If audit result is **fail**, publication is blocked.
+- If audit result is **pass**, maintainers can mark module as `releaseReady` and publish wiki/release visibility.
+
+## Multiplayer Clarification
+
+Steamworks multiplayer remains a planned direction but is currently blocked by missing Steamworks implementation on the game developer side.
