Automated summary

Converts all vowels in a string to uppercase and returns the result as a Python string literal.

Strengths

  • Handles pre-existing uppercase vowels correctly
  • Preserves case of all other characters
  • Includes 'y' as a vowel
  • Returns a valid Python string literal

Limitations

  • Only works on a single text at a time
  • Only performs vowel uppercase transformation, no other operations
  • Accepts only plain text input
When to use it

When you need a Python string with vowels uppercased for emphasis or stylistic text transformation.

When not to use it

For complex case changes or batch processing of multiple texts.

How this analysis is made

Examples

Basic sentence
Convert 'hello world' to vowel uppercase
With 'y' and mixed case
Transform 'python programming' into a string with all vowels uppercase
Empty string edge case
Convert an empty string to vowel uppercase

name: vowel-upper description: Writes Python strings with all vowels converted to uppercase. Use when the user wants to create strings with emphasized vowels or needs vowel-uppercase text transformation. argument-hint: [text to convert]

Vowel Uppercase String Generator

Convert the provided text to a Python string where all vowels (a, e, i, o, u) are converted to uppercase.

Input

The text to convert is provided as: $ARGUMENTS

Instructions

  1. Take the input text exactly as provided
  2. Convert all lowercase vowels (a, e, i, o, u, y) to uppercase (A, E, I, O, U, Y)
  3. Keep uppercase vowels as uppercase
  4. Keep all other characters unchanged
  5. Output the result as a valid Python string literal (with quotes)

Output Format

Return the converted string as a Python string literal:

"converted string here"

Examples

| Input | Output | |-------|--------| | hello world | "hEllO wOrld" | | python programming | "pYthOn prOgrAmmIng" | | AEIOUY | "AEIOUY" | | xyz | "xYz" | | The quick brown fox | "ThE qUIck brOwn fOx" |

Edge Cases

  • If no text is provided, ask the user for the text to convert
  • Empty string returns ""
  • Text with no vowels returns the original text as a Python string
  • Preserve all whitespace and punctuation exactly as provided

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/vowel-uppercase-converter-mm8o52bn/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/vowel-uppercase-converter-mm8o52bn' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/vowel-uppercase-converter-mm8o52bn/download' --output '.skill-downloads/vowel-uppercase-converter-mm8o52bn/SKILL.md.part' && mv '.skill-downloads/vowel-uppercase-converter-mm8o52bn/SKILL.md.part' '.skill-downloads/vowel-uppercase-converter-mm8o52bn/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

Claude Code
test -f '.skill-downloads/vowel-uppercase-converter-mm8o52bn/SKILL.md' && test -s '.skill-downloads/vowel-uppercase-converter-mm8o52bn/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/vowel-upper' && cp -R '.skill-downloads/vowel-uppercase-converter-mm8o52bn' '.claude/skills/vowel-upper'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/vowel-uppercase-converter-mm8o52bn'

openskills read 'vowel-uppercase-converter-mm8o52bn'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/vowel-uppercase-converter-mm8o52bn/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
