Baseline cross-project coding conventions for naming, readability, immutability, and code-quality review. Use detailed frontend or backend skills for framework-specific patterns.
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.

# Coding Standards & Best Practices
Baseline coding conventions applicable across projects.
This skill is the shared floor, not the detailed framework playbook.
- Use `frontend-patterns` for React, state, forms, rendering, and UI architecture.
- Use `backend-patterns` or `api-design` for repository/service layers, endpoint design, validation, and server-specific concerns.
- Use `rules/common/coding-style.md` when you need the shortest reusable rule layer instead of a full skill walkthrough.
## When to Activate
- Starting a new project or module
- Reviewing code for quality and maintainability
- Refactoring existing code to follow conventions
- Enforcing naming, formatting, or structural consistency
- Setting up linting, formatting, or type-checking rules
- Onboarding new contributors to coding conventions
## Scope Boundaries
Activate this skill for:
- descriptive naming
- immutability defaults
- readability, KISS, DRY, and YAGNI enforcement
- error-handling expectations and code-smell review
Do not use this skill as the primary source for:
- React composition, hooks, or rendering patterns
- backend architecture, API design, or database layering

The line at the top of this page pins the label git:20260702.69ee5ed, 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.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
