+# Seth-Workflow-April-2026
+
+This repository contains a shareable AI-assisted development workflow. It is a reference and template — not an active project with running services.
+
+## What This Is
+
+A collection of rules, templates, hooks, and methodology guides for working with AI coding assistants (Claude Code, etc.). The rules in `rules/` are designed to be copied into `.claude/rules/` in any project.
+
+## Structure
+
+| Directory | Purpose |
+|-----------|---------|
+| `rules/` | Core behavior rules (copy to `.claude/rules/`) |
+| `templates/` | File templates for bootstrapping new projects |
+| `hooks/` | Claude Code hooks (pre-push secret scanning) |
+| `settings/` | Example Claude Code configuration |
+| `workflows/` | Human-readable methodology guides |
+| `docs/` | Philosophy and customization documentation |
+
+## Conventions
+
+- Conventional commits: `feat:`, `fix:`, `docs:`, `refactor:`, `test:`, `chore:`
+- All rules are self-contained markdown files with no external dependencies
+- Templates use `<placeholder>` syntax for values the user fills in
+- No credentials, IPs, or personal information anywhere in this repo
