Rules file converter

Write a rule once and use it in every coding agent your team runs. Paste a rule in any agent's format and get the file path and frontmatter for 11 targets, keeping when the rule applies. Formats checked against each vendor's docs on 2026-10-19. Nothing leaves your browser.

- Use standalone components, directives and pipes. Do not create NgModules, and do not set standalone: true; it is the default.
- Use input(), output() and model() functions instead of @Input and @Output decorators.
- Use signals for component state, computed() for derived values, and update() or set() to change them.
- Use the inject() function instead of constructor injection. Singleton services use providedIn: 'root'.
- Use built-in control flow (@if, @for, @switch) instead of *ngIf, *ngFor and *ngSwitch. Every @for needs a track expression.
- Use class and style bindings instead of ngClass and ngStyle, and do not import CommonModule.
- Put host bindings and listeners in the host object of the decorator, not @HostBinding or @HostListener.
- Lazy load feature routes with loadComponent or loadChildren.
- Use NgOptimizedImage for static images.
- Keep templates simple; move logic into computed() signals or component methods.

How scope maps between agents

When it applies	Cursor .mdc	Claude Code	GitHub Copilot	Kiro	Antigravity / Devin
Always on	alwaysApply: true	no paths	applyTo: "**"	inclusion: always	trigger: always_on
Matching files	globs	paths	applyTo	inclusion: fileMatch	trigger: glob
Agent decides	description	(use a Skill)	description (VS Code)	inclusion: auto	trigger: model_decision
Manual	no description, no globs	(use a Skill)	neither (VS Code)	inclusion: manual	trigger: manual

AGENTS.md, GEMINI.md and Codex have no frontmatter: put the file in the folder it applies to. Zed reads only the first instruction file it finds, so a .cursorrules file wins over AGENTS.md there.

Rules formats keep changing

Get one email a week when a coding agent changes where it reads rules or how it scopes them.
