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.

Your rule (any agent's format, frontmatter included)

- Generate files with php artisan make:* so they land in the right place with the right namespace.
- Validate with Form Request classes or $request->validate(); only use validated() data for writes.
- Protect against mass assignment with $fillable on every model; never pass $request->all() to create() or update().
- Eager load relations with with() to avoid N+1 queries.
- Authorize with policies and Gate, not ad hoc role checks in controllers.
- Read settings with config(), never env(), outside the config folder.
- Register middleware, exceptions and routing in bootstrap/app.php; there is no HTTP Kernel in current Laravel.
- Change the schema only with new migrations; never edit a migration that has already run.
- Push slow work (email, external APIs) to queued jobs.
- Write Pest or PHPUnit feature tests and run php artisan test before finishing.

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.
