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

Installation

Install the Test Discipline 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/bradygaster/squad/tree/dev/packages/squad-cli/templates/skills/test-discipline
Enable the skill in any chat where you want it available.

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/bradygaster/squad.git /tmp/squad
mkdir -p .claude/skills
cp -r /tmp/squad/packages/squad-cli/templates/skills/test-discipline .claude/skills/test-discipline

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

Use it in TypingMind

Enable Test Discipline 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 Test Discipline 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 Test Discipline 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.

Context

Use this skill whenever a change affects an API, public interface, workflow contract, generated artifact, or user-observable behavior. A passing status-only test is not evidence that the intended artifact or contract is correct.

Patterns

Update tests in the same change as an API, signature, export, or public-interface change.
Make assertions name and inspect the offending artifact, output, or configuration field—not just an exit code or broad success status.
Mutation-test critical gates by changing the real source or emitted artifact and proving the assertion turns red.
Exercise every caller path for a changed parser, normalizer, or helper; isolated unit coverage can miss the integration path that invokes it differently.
Reproduce working-tree-only failures locally when the contract depends on index, filesystem, line-ending, or generated-output state.
Keep expected inventory arrays synchronized with the files they enumerate.

Examples

A workflow-compilation test mutates the source workflow, compiles it, and inspects the emitted safe-output contract. A repair-script test constructs the actual index/blob/worktree state that the repair routine must handle instead of a simplified fixture.

Anti-Patterns

Calling a test sufficient because it observes only a successful process exit
Mutating a hand-built fixture instead of the source or artifact protected by the gate
Testing a helper while omitting production callers
Treating a local checkout defect as something CI alone can validate

Frequently asked questions

What does the Test Discipline AI skill do?

Design assertions that prove the actual contract and fail on realistic regressions

Why use Test Discipline on TypingMind?

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

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/bradygaster/squad/tree/dev/packages/squad-cli/templates/skills/test-discipline. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Test Discipline?

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 Test Discipline?

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

Is the Test Discipline AI skill free?

Yes. It is published on GitHub by bradygaster 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.
