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.
7 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by pedronauck on GitHub. Read the source before you install it.

Installation

Install the Testing Boss 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/pedronauck/skills/tree/main/skills/mine/testing-boss
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/pedronauck/skills.git /tmp/skills
mkdir -p .claude/skills
cp -r /tmp/skills/skills/mine/testing-boss .claude/skills/testing-boss

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

Use it in TypingMind

Enable Testing Boss 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 Testing Boss 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 Testing Boss 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.

Testing Boss

Choose tests that can expose the changed behavior's failure. Use the existing suite at the lowest layer that can observe the invariant; reuse fixtures and utilities before creating new files.

Assert observable results, not mock behavior or implementation structure. Keep mocks at unit-test I/O boundaries; use real integration evidence for integration claims.
When a test exposes a regression, fix production code. Change an incorrect test only with evidence that its contract is wrong or intentionally changed; preserve valid coverage.
Existing tests or stronger build/codegen/link/render checks may already own the invariant. Do not add prose, CSS, generated-output, configuration, or snapshot tests without a real artifact contract and a reason the owning gate is insufficient.
Coverage and mutation scores help find blind spots; they do not replace a behavioral oracle. Do not add production branches or methods solely for tests.
Run affected checks, then the project's delivery gates. Reuse results for unchanged inputs and expand only for a failure, relevant edit, or unresolved risk. Match regression reproduction to the failure; avoid a second ceremony when red/green evidence already exists.

References by Question

Read the relevant section, including its contract dependencies, when the question arises; test authorship by an agent does not itself require every reference.

Question	Reference
Which layer or suite owns the invariant?	`references/foundations.md`
How should selectors, waits, data, or mocks work?	`references/patterns.md`
Why is a test brittle or passing for the wrong reason?	`references/antipatterns.md`
How should agent-generated tests be evaluated?	`references/ai-writes-tests.md`
How should flakiness or contract/property/mutation checks be handled?	`references/ci-automation.md`
How should an LLM/agent outcome be evaluated?	`references/llm-eval.md`

references/sources.md holds supporting sources. Completion evidence can be a concise command/result summary; no separate report is needed unless the task's artifact contract requires one.

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 Testing Boss AI skill do?

Why use Testing Boss on TypingMind?

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

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/pedronauck/skills/tree/main/skills/mine/testing-boss. 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 Testing Boss?

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 Testing Boss?

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

Is the Testing Boss AI skill free?

It is published on GitHub by pedronauck. 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.
