  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 1 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by olorehq on GitHub. Read the source before you install it.

Installation

Install the Regex Tester AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/olorehq/olore.git /tmp/olore
mkdir -p .claude/skills
cp -r /tmp/olore/vault/packages/ms-agent-framework/latest/contents/dotnet/samples/02-agents/Harness/Harness_Step04_CodeExecution/skills/regex-tester .claude/skills/regex-tester
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Regex Tester in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Regex Tester on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Regex Tester is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Usage

When the user asks you to create, validate, or debug a regular expression:

  1. Understand the requirement — clarify what the pattern should match and what it should reject.
  2. Consult the cheatsheet — review references/regex-cheatsheet.md for syntax reminders if needed.
  3. Write and execute test code — use the execute_code tool to run Python code that:
    • Compiles the regex with re.compile()
    • Tests it against a set of positive examples (should match) and negative examples (should not match)
    • Extracts and displays any capturing groups
    • Reports pass/fail for each test case
  4. Iterate — if any test fails, refine the pattern and re-run until all cases pass.
  5. Present the result — give the user the final pattern, explain what each part does, and show the test results.

Example Test Script

python
import re

pattern = re.compile(r'^[\w.+-]+@[\w-]+\.[\w.-]+$')

positives = ["user@example.com", "first.last+tag@sub.domain.org"]
negatives = ["@missing.com", "no-at-sign", "spaces in@address.com"]

for s in positives:
    assert pattern.match(s), f"FAIL: expected match for '{s}'"
for s in negatives:
    assert not pattern.match(s), f"FAIL: expected no match for '{s}'"

print("All tests passed!")

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Regex Tester AI skill do?

Validate, test, and debug regular expressions by executing them against sample inputs. Use when asked to build, verify, or explain a regex pattern.

Why use Regex Tester on TypingMind?

Because you install it once and use it with any model. Regex Tester is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Regex Tester in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/olorehq/olore/tree/main/vault/packages/ms-agent-framework/latest/contents/dotnet/samples/02-agents/Harness/Harness_Step04_CodeExecution/skills/regex-tester. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Regex Tester?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Regex Tester?

As many as you like. As long as a model supports skills, you can use Regex Tester with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Regex Tester AI skill free?

Yes. It is published on GitHub by olorehq under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
