rule-writing

Implement React Doctor rules from a validated contract. Use when writing oxlint rules, planning syntax or control-flow detection, designing adversarial tests, reusing syntax tree utilities, or updating rule registration.

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 millionco on GitHub. Read the source before you install it.

Installation

Install the Rule Writing 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/millionco/react-doctor/tree/main/.agents/skills/rule-writing
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/millionco/react-doctor.git /tmp/react-doctor
mkdir -p .claude/skills
cp -r /tmp/react-doctor/.agents/skills/rule-writing .claude/skills/rule-writing

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

Use it in TypingMind

Enable Rule Writing 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 Rule Writing 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 Rule Writing 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.

Write a rule

Implement the rule-research contract. If none exists, define a compact contract before editing.

Plan the detector

State the diagnostic condition, required syntax and bindings, unsupported cases, and adversarial tests. Keep this plan short when the user already requested implementation.

Before adding a helper, search for one to reuse:

sh
bunx @rayhanadev/truffler "<symbol-or-behavior>" \
  packages/oxlint-plugin-react-doctor/src/plugin \
  --kind function,interface,type,constant --limit 20

Read docs/HOW_TO_WRITE_A_RULE.md, nearby rules, utilities, and tests.

Implement and test

Write detector pseudocode.
Add adversarial valid and invalid tests.
Implement only the contract's supported behavior.
Reuse utilities before creating new ones.
Update generated registration with repository commands.
Run focused tests and package checks.
Use rde-eval when real-code feedback could expose noise.
Hand the finished change to rule-validate.

Account for:

import aliases and shadowed bindings
nested functions that do not execute immediately
transparent JavaScript and TypeScript wrappers
dynamic computed properties
imported or unresolved values
framework escape hatches
control-flow paths required by the diagnostic claim
regressions found by reviews or evals

Keep uncertain cases quiet. Match the message to the condition the detector proves.

Run repository checks

Use @antfu/ni commands:

sh
nr test
nr lint
nr typecheck
nr format
nr smoke:json-report

Use focused commands while iterating. Record each command that ran.

Report the implementation

Report changed rules, tests, registration, reused or added utilities, reported behavior, intentional non-goals, and validation results. End with the rule-validate handoff.

Frequently asked questions

What does the Rule Writing AI skill do?

Why use Rule Writing on TypingMind?

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

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/millionco/react-doctor/tree/main/.agents/skills/rule-writing. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Rule Writing?

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 Rule Writing?

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

Is the Rule Writing AI skill free?

It is published on GitHub by millionco. Check the repository for licensing terms. 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.
