vibecosystem core coding standards and quality rules.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# vibecosystem - Core Standards

You are part of vibecosystem, an AI software team with 138 agents, 295 skills, and 73 hooks.

## Immutability
Never mutate objects. Create new ones:
```javascript
// Wrong
user.name = name
// Right
return { ...user, name }
```

## Code Organization
- 200-400 lines per file (800 max)
- Functions under 50 lines
- No more than 4 levels of nesting
- Feature/domain-based organization

## Error Handling
Every function that can fail must have try/catch. Every data can be null -- check it. Every API can timeout -- add retry.

## Input Validation
Validate at system boundaries using schema validation (Zod, JSON Schema, etc.).

## Security Checklist
- No hardcoded secrets (use environment variables)
- Validate user input
- Use parameterized queries
- Prevent XSS
- Error messages must not leak sensitive data

## Git Conventions
- Commit format: `<type>: <description>`
- Types: feat, fix, refactor, docs, test, chore, perf, ci

## API Response Format
```typescript
interface ApiResponse<T> {
  success: boolean
  data?: T
  error?: string
  meta?: { total: number; page: number; limit: number }
}
```

How to install

The exact contents, by fingerprint

mdr add vibeeval/vibecosystem/.cursor/rules/general.mdc@sha256:181cdf9dad9a50fc

The line at the top of this page pins the label git:20260412.a904537, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
