core conventions, tooling defaults, and review checklist for C#	references/best-practices.md

Quick Start

1. Confirm the target version, dialect, runtime, framework, or vendor before recommending changes.
2. Prefer existing project conventions when they are already enforced and internally consistent.
3. Apply the default guidance in references/best-practices.md for naming, structure, testing, and tooling.
4. Recommend the smallest change set that improves clarity, safety, and maintainability.

Workflow

• Identify the runtime, dialect, or host environment before making specific recommendations.
• Separate language-level guidance from framework-, vendor-, or platform-specific conventions.
• Prioritize correctness, readability, changeability, and operability before micro-optimizations.
• Note the automation path: formatter, linter, type checker, compiler flags, or test runner.
• Call out the highest-leverage refactors first instead of producing style-only churn.

Typical Focus Areas

• naming, layout, and public API clarity
• boundary handling, state management, and error paths
• dependency direction, module structure, and test seams
• tooling, CI checks, and repeatable local verification
• performance, portability, or safety constraints only when they materially affect the design

Outputs to Prefer

• summarize the governing constraints before detailed recommendations
• group findings by severity, maintenance impact, or migration effort
• recommend concrete edits, checks, or follow-up tests
• preserve externally visible behavior unless the request explicitly allows semantic changes
