Working rules for quick browser tools.

When a browser tool is enough and when a specialized system is better.

Check character limits, slugs, snippets and lists before publishing.

Check JSON, Base64, regex, URL parameters and hashes without heavy setup.

Separate duplicate query keys, UTM values, encoded spaces and JSON handoffs clearly.

Interpret common SyntaxError messages, context snippets and fast fixes for browser payloads.

Make small data sets readable before they move into sheets, CMS or scripts.

Prepare campaign parameters, names and short copy consistently.

Check contrast, color codes, shadows and responsive sizes with clear logic.
