common-best-practices skillA
This file is byte-identical to the first copy the registry indexed, one of 3 copies on public GitHub. Same content hash, same audit grade.
common-best-practices is agent-read markdown (skill) from hoangnguyen0403/agent-skills-standard: Enforce SOLID principles, guard-clause style, function size limits, and intention-revealing naming across all languages. Use when refactoring for readability, applying clean-code patterns, reviewing naming conventions, or reducing function complexity..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Global Best Practices ## **Priority: P0 (CRITICAL)** ## Core Principles - **SOLID**: Follow SRP (One reason to change), OCP (Open to extension), LSP, ISP, DIP. - **KISS/DRY/YAGNI**: Favor readability. Abstract repeated logic. No " in case" code. - **Naming**: Use intention-revealing names (`isUserAuthenticated` > `checkUser`). Match language casing. ## Code Hygiene - **Size Limits**: Functions < 30 lines. Services < 600 lines. Utils < 400 lines. - **Early Returns**: Use guard clauses. Avoid deep nesting. - **Comments**: Explain **why**, not **what**. Refactor bad code; don't comment it. - **Input**: Validate/sanitize all external inputs. ## Anti-Patterns - **No Hardcoded Constants**: Use named config/env vars. - **No Deep Nesting**: Use guard clauses. - **No Global State**: Prefer dependency injection. - **No Empty Catches**: Always handle, log, or rethrow. ## References - [Code Structure Patterns](references/CODE_STRUCTURE.md) — file/function organization - [Effectiveness Guide](references/EFFECTIVENESS.md) — practical application examples

Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
