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.
Scope: Only for matching files (**/*.vue)

Save as: .cursor/rules/vue.mdc
--- globs: **/*.vue alwaysApply: false --- - Write single-file components with <script setup lang="ts">. Do not use the Options API or defineComponent with a setup() function. - Declare props and emits with type-based defineProps<...>() and defineEmits<...>(). - Use defineModel() for v-model on a component instead of a modelValue prop plus an update:modelValue emit. - Prefer ref() over reactive(). Do not destructure a reactive() object; that breaks reactivity. - Use computed() for derived values and watch() only for side effects; never copy a prop into local state just to read it. - Use useTemplateRef() for template refs. - Give every v-for a stable :key from the data, and never put v-if and v-for on the same element. - Do not mutate props; emit an event or update the model instead. - Move reusable stateful logic into composables named useSomething in the composables folder.

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.
