Use this skill whenever a user wants to install, configure, troubleshoot, or write Python application code for encoding and decoding nested query strings with the qs-codec package, including comparing or composing qs-codec with urllib.parse.urlencode, parse_qs, parse_qsl, and URL components. This skill helps produce practical qs_codec.decode, qs_codec.encode, qs_codec.loads, and qs_codec.dumps snippets, choose DecodeOptions and EncodeOptions, explain option tradeoffs, and avoid qs-codec edge-case pitfalls around lists, dot notation, duplicates, null handling, charset sentinels, depth limits, URL replacement, and untrusted input.
