Text Statistics

Workflow

1. Confirm that the requested result is a count. Do not substitute this Skill for rewriting, translation, sentiment, model-token billing, or semantic summarization.
2. Prefer scripts/text_stats.py --input <UTF8_FILE> for file content. Both input forms reject UTF-8 payloads over 1 MiB; use --text <TEXT> only for short, non-secret text because command histories can retain arguments.
3. Parse the JSON written to stdout. Treat a nonzero exit code or stderr as a failure; do not invent missing counts.
4. Explain the counting rule if the result will be compared with an editor, tokenizer, or language-specific tool.

Commands

python -B scripts/text_stats.py --text "Hello Agent 世界" # 直接传入短文本；-B 防止产生 Python 字节码缓存
python -B scripts/text_stats.py --input .\sample.txt # 从 UTF-8 文件读取；脚本会限制为 1 MiB 并拒绝目录/无效编码

The input file must be valid UTF-8 and no larger than 1,000,000 bytes. The script never writes a file and never accesses the network.

Output contract

Successful stdout is exactly one JSON object containing integer words, characters, and lines fields. Diagnostics go to stderr and failures return a nonzero exit code. The input text is never echoed.

Counting rules and gotchas

• A Latin letter, digit, or underscore run counts as one word-like token; each Han character counts as one. This is a teaching rule, not a universal linguistic definition.
• characters counts Python Unicode code points, including whitespace and newline characters. It is not a byte count or a model tokenizer count.
• CRLF, LF, and CR are treated as line separators. Empty text has zero logical lines; a trailing separator introduces a final empty logical line.
• Do not promise equality with Microsoft Word, an IDE, or an LLM tokenizer unless their rules have been separately checked.
