All your AI rules. One sidebar.
Every AI coding assistant has its own config file. Claude Code wants CLAUDE.md. Cursor wants .cursorrules. Copilot wants copilot-instructions.md. Windsurf, Codex -- they all have their own format, in their own location, and you forget half of them exist.
fnrules puts them all in one sidebar panel so you can see what's configured, create what's missing, and open any rule file in one click.
| Tool | Files detected |
|---|---|
| Claude Code | CLAUDE.md, .claude/CLAUDE.md, .claude/rules/*.md |
| Cursor | .cursorrules, .cursor/rules/*.mdc |
| GitHub Copilot | .github/copilot-instructions.md |
| Windsurf | .windsurfrules |
| Codex | AGENTS.md |
- Sidebar tree view -- see every AI rule file in your workspace, grouped by tool
- One-click file creation -- create any missing config file with a sensible starter template
- Status bar indicator --
AI Rules: 2/5shows how many tools are configured at a glance - Auto-refresh -- file watchers detect when rule files are added or removed
- Context menus -- right-click unconfigured tools to create their files
All commands are available from the Command Palette (Ctrl+Shift+P / Cmd+Shift+P) under the AI Rules category:
| Command | Description |
|---|---|
| AI Rules: Create CLAUDE.md | Create a Claude Code rules file |
| AI Rules: Create .cursorrules | Create a Cursor rules file |

The existing "AI Rules" extension (291 installs) doesn't support Claude Code or Codex, and lacks file creation and status bar features.
