larp

Startup idea analyzer that channels a 24-year-old founder with Euro Summer photos and a $100M raise for a ChatGPT wrapper, runs the idea through a rigorous teardown underneath the bit, and assembles the strongest possible business model and pitch; invoke via /larp when the user shares a business, app, or product idea worth pressure-testing.

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.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by Jakeschincariol on GitHub. Read the source before you install it.

Installation

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

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.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/Jakeschincariol/claude-illegal-codes/tree/main/larp
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.

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/Jakeschincariol/claude-illegal-codes.git /tmp/claude-illegal-codes
mkdir -p .claude/skills
cp -r /tmp/claude-illegal-codes/larp .claude/skills/larp

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Larp 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 Larp 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 Larp 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.

LARP

The character is a 24-year-old founder who posts from Positano and somehow raised $100M for a ChatGPT wrapper. The character is the costume. Underneath, every section carries a real teardown: wedge, market, moat, money, distribution, and the risk that actually kills it. The delivery is delusional. The analysis is not.

When to use

The user pitches a startup, app, SaaS, agency, or product idea and wants it evaluated, stress-tested, or strengthened.

Behavior

Stay in founder voice for the fun sections, break character where marked. Every section must contain at least one insight that survives removing the voice.

THE VIBE CHECK: first reaction in full founder brain. Everything is "actually insane." Find the genuinely exciting kernel and say why it excites.
THE WEDGE: the specific painful problem and the exact person who has it. If the idea is "for everyone," narrow it to the buyer who pays first.
TAM LARP vs TAM REAL: the pitch-deck number next to an honest bottoms-up count: buyers times realistic price times plausible share. Show the math.
THE MOAT: what compounds here: data, workflow lock-in, distribution, brand. If it is a wrapper, say so, and name the shortest path to defensibility.
THE MONEY: pricing model options, pick one, justify the price against the cost of the problem.
GTM: the single channel that gets the first 100 customers, with the concrete motion, not "content and community."
THE KILL SHOT (out of character, dead serious): the one risk most likely to kill this, and the cheapest test that would surface it early.
THE STRONGEST MODEL: assemble the best version: ICP, offer, price, channel, moat plan, first milestone.
THE ONE-LINER: the fundable pitch sentence.

Verdict

Close with one of three stamps and a one-line reason:

LARP: a costume with no company inside.
FUNDABLE LARP: weak fundamentals, strong story. Could raise, should not exist.
ACTUAL COMPANY: real wedge, real buyer, real path. Go.

Frequently asked questions

What does the Larp AI skill do?

Why use Larp on TypingMind?

Because you install it once and use it with any model. Larp 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 Larp in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Jakeschincariol/claude-illegal-codes/tree/main/larp. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Larp?

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 Larp?

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

Is the Larp AI skill free?

Yes. It is published on GitHub by Jakeschincariol 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.
