solo

Work on one hard mathematics problem in this session yourself, with no sub-agents: reason in stages, record each settled step in a notes file so that nothing written is lost if a response is cut off, and end with a self-contained proof.md. Usage: /math-proof:solo <the problem, stated in full, or the path of a file holding it>.

  • 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 anthropics on GitHub. Read the source before you install it.

Installation

Install the Solo 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.
    https://github.com/anthropics/claude-plugins-official/tree/main/plugins/math-proof/skills/solo
  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.

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/anthropics/claude-plugins-official.git /tmp/claude-plugins-official
mkdir -p .claude/skills
cp -r /tmp/claude-plugins-official/plugins/math-proof/skills/solo .claude/skills/solo
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Solo 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 Solo 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 Solo 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.

math-proof: solo

You solve the problem yourself, in this session. There are no sub-agents and no rounds: just you, a notes file and, at the end, proof.md.

Arguments. The invoking message reads: $ARGUMENTS It gives the problem and, optionally, the run directory. Read it this way. A token of the form DIR=path at its start sets the run directory (the path quoted if it contains spaces); remove it. Any other leading token of the form NAME=value, where NAME is a word of two or more capital letters and underscores and value is a whole number, is a setting this skill does not have: tell the user in one sentence that /math-proof:solo takes only DIR=path before the problem (round and wave settings belong to /math-proof:siege), and that if the token is part of the problem itself the problem can be given as a file path instead, and stop. If what remains is a single line that, taken as a whole — surrounding whitespace and one pair of enclosing quotation marks removed, backslash-escaped spaces read as spaces — is the path of an existing file (it may contain spaces; check with Read or Glob, not the shell), that file is the problem file; if no such file exists and what remains can only be a file path — a single line ending in .md, .txt or .tex, or a single token (no spaces once the quotes are removed) containing "/" or "" — tell the user in one sentence that no file exists at the absolute path you looked for (give it) and that the problem can instead be given in full as text after the command, and stop; otherwise everything that remains, to the end of the message, IS the problem statement, verbatim — mathematics, line breaks and all ("n=3", "N=pq" and "AB=AC" are mathematics, not settings). The run directory DIR defaults to ./math-proof-solo under the current directory; use DIR's absolute path everywhere below. If the message holds neither a readable problem file nor any problem text, say so in one sentence — with the usage, /math-proof:solo <problem statement, or the path of a file holding it> — and stop.

Setup. The run's files are DIR/problem.md (the problem), DIR/notes.md (your notes) and DIR/proof.md (the deliverable). Create DIR with mkdir -p. If DIR/notes.md already exists, this problem was already being worked on in DIR: check that DIR/problem.md is the same problem you were given (compare the text, ignoring differences in whitespace and line endings; for a file, cmp) — if it differs, say in one sentence that DIR holds work on a different problem and that DIR=<another directory> selects a fresh one, and stop; if it is the same, read DIR/notes.md, and DIR/proof.md if it exists. If they record the solution as complete (proof.md written and nothing in the notes still to do), the earlier session finished: say where proof.md is and that DIR=<another directory> starts a fresh attempt, and stop. Otherwise the earlier session ended before it finished, and whatever reasoning it had not written down is lost: continue from the last point recorded there rather than starting over. If DIR/notes.md does not exist yet, put the problem at DIR/problem.md: if it came as a file, copy that file there byte for byte with cp; if it came as text in the invoking message, Write exactly that text (nothing added, removed or reworded). Then Read DIR/problem.md in full; it is the authoritative text of the problem. Use the shell for nothing but that mkdir, cp and cmp.

The task. Solve the problem stated in DIR/problem.md; the deliverable is DIR/proof.md. After reasoning, write your answer. This task runs as a conversation that can span many messages, each with a bounded output allowance; a message that is cut off is normally followed by a request to continue, and only what you have WRITTEN (not unwritten reasoning) is guaranteed to carry into the next message. So write your work product out as you go, in a notes file, DIR/notes.md: whenever you settle something — a lemma and its proof, a reduction, a dead end and why it is dead, the precise statement you are now attempting — write it down before reasoning further. A partial answer is much more useful than none. Writing to the notes is not finishing — keep going after each write. Important: each message's output allowance also covers your private reasoning, and it is far smaller than a hard problem deserves — a message spent entirely on reasoning, with nothing written, gets cut off, and unwritten reasoning should be assumed lost. So do not try to finish in one message. Work in stages: early in EVERY message, before any long derivation, write your current plan and the precise statement you are attempting to DIR/notes.md; then reason toward the next concrete intermediate result, append it to the notes as soon as you have it, and continue. Many short written steps beat one long unwritten one. If a message of yours is cut off, re-read DIR/notes.md and continue from the last thing written there; never start over. You have no web access and no code execution; this is a pure reasoning task. When the problem is resolved, or you have taken it as far as you can, write your complete solution to DIR/proof.md. proof.md is read on its own by a referee who cannot open any other file (not your notes either), so it must be self-contained: every argument the solution relies on is written out in full there. Work unattended: there is no one to answer questions, so never stop to ask.

When DIR/proof.md is written, reply briefly: where proof.md is, and whether it resolves the problem completely or, in proof.md's own words, what it leaves open.

Frequently asked questions

What does the Solo AI skill do?

Work on one hard mathematics problem in this session yourself, with no sub-agents: reason in stages, record each settled step in a notes file so that nothing written is lost if a response is cut off, and end with a self-contained proof.md. Usage: /math-proof:solo <the problem, stated in full, or the path of a file holding it>.

Why use Solo on TypingMind?

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

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/anthropics/claude-plugins-official/tree/main/plugins/math-proof/skills/solo. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Solo?

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 Solo?

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

Is the Solo AI skill free?

Yes. It is published on GitHub by anthropics under the Apache-2.0 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.
