Configuration settings should align with official language documentation and established community standards rather than arbitrary personal preferences. This applies to indentation styles, formatter configurations, and syntax requirements.

For language-specific settings, consult official documentation:

For tool configurations, ensure commands and arguments are syntactically correct:

# Correct formatter configurations
formatter = { command = "prettier", args = ["--parser", "typescript"] }
formatter = { command = "biome", args = ["format", "--stdin-file-path=a.js"] }
formatter = { command = "deno", args = ["fmt", "--ext", "js"] }

# Use full 6-character hex codes, not 3-character shortcuts
"ui.background" = { bg = "#262335" }  # not "#263"

This ensures consistency with ecosystem expectations and prevents configuration errors that could break functionality.
