name: office-symbol-helper description: Query, explain, copy, and safely normalize professional symbols used in Word, Excel, technical writing, formulas, chemistry, engineering, and SI units. Use when users ask for a special symbol, mathematical operator, Greek letter, superscript or subscript, chemical notation, unit symbol, arrow, check mark, Unicode code point, or want to normalize a short piece of symbol-heavy text. This free skill handles text up to 500 characters and does not upload or modify DOCX/XLSX files.

Word/Excel 专业符号助手

小葱技能7w4.net有完整的技能分类。

Use the bundled script for deterministic lookup and conversion. Keep all work local.

Choose the operation

• Search by Chinese name, English name, alias, character, or code point: run search.
• Show available curated categories: run categories.
• Browse a curated category: run browse.
• Normalize short text only after the user requests conversion: run convert with an explicit mode.
• Explain one displayed result using its note, Unicode name, and code point. Do not invent a standard or claim a character is universally preferred.

Commands

Run from this skill directory:

python3 scripts/symbol_helper.py categories
python3 scripts/symbol_helper.py browse mathematics
python3 scripts/symbol_helper.py search "大于等于"
python3 scripts/symbol_helper.py search "U+2265"
python3 scripts/symbol_helper.py convert "3x5，20°C，a!=b" --mode common
python3 scripts/symbol_helper.py convert "H2SO4 + 2NaOH -> Na2SO4 + 2H2O" --mode chemistry
python3 scripts/symbol_helper.py self-test

Return the requested symbol first, then its name, code point, copy-ready example, and one short caution when relevant.

Conversion safety

• Limit conversion to 500 characters.
• Use common only for explicit operator and temperature patterns.
• Use chemistry only when the user identifies the input as a chemical formula or equation.
• Use units only for explicit measurement expressions.
• Show the converted text and summarize replacements. Never silently overwrite user files.
• Preserve ambiguous x, hyphens, Greek letters, micro signs, and slashes unless the selected mode has a deterministic rule.

Boundaries

• Do not open, upload, scan, or rewrite complete DOCX/XLSX files.
• Do not promise exhaustive industry-standard compliance.
• Do not present Unicode existence as proof that a symbol is correct in a specific profession.
• For full-document review or batch repair, explain that this free version does not provide that capability yet.

Read references/sources.md only when the user asks about coverage, authority, standards, or data provenance.

这个 Skill 质量中规中矩，能够较好地完成符号查询和规范转换任务。优点是操作简单、支持中文搜索、转换安全（有长度限制和模式区分），边界清晰不会乱改文件。不足是符号库内容偏少，缺少使用说明文档，部分功能藏得比较深。对于常用符号处理够用，但想要更丰富的符号支持可能需要其他工具配合。
