quality-engineering-test-healing

Failure taxonomy and allowed/forbidden repairs for a failing E2E test. Use when a Playwright/Maestro/Detox/XCUITest/Espresso/Appium test fails and you must decide whether to repair the test or route to a real bug.

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.
4 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by HoangNguyen0403 on GitHub. Read the source before you install it.

Installation

Install the Quality Engineering Test Healing 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/HoangNguyen0403/agent-skills-standard/tree/develop/.agents/skills/quality-engineering/quality-engineering-test-healing
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/HoangNguyen0403/agent-skills-standard.git /tmp/agent-skills-standard
mkdir -p .claude/skills
cp -r /tmp/agent-skills-standard/.agents/skills/quality-engineering/quality-engineering-test-healing .claude/skills/quality-engineering-test-healing

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

Use it in TypingMind

Enable Quality Engineering Test Healing 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 Quality Engineering Test Healing 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 Quality Engineering Test Healing 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.

Quality Engineering: Test Healing

Priority: P0 (CRITICAL)

Failure Classes

SELECTOR_DRIFT (id/locator changed) · TIMING_SYNC (race/wait, no state change) · DATA_ENV (fixture/seed/env stale) · INFRA (network/runner/flake) · REAL_REGRESSION (product behavior actually changed).

Classify from evidence: trace/screenshot/DOM diff supports a drift/timing/data explanation, or the product diff shows an intentional behavior change (REAL_REGRESSION).

Allowed Repairs

Move the locator up the selector ladder (e.g., getByRole if the ID changed); replace a sleep with an explicit state wait; fix a stale fixture/seed; retry only for INFRA.

Forbidden Repairs

Never weaken an assertion. Never add test.skip/fixme; a test that must stop gating goes to quarantine per quality-engineering-flaky-triage with a ticket + expiry, and keeps running. Never widen a matcher. Never inflate a timeout by more than 2x. Never blind --update-snapshots. Never catch-and-continue. Never touch production code — that is REAL_REGRESSION, not a heal.

Verdicts

HEALED (repair verified by 3 consecutive green reruns, ASSERTION_DELTA: none) · REAL_BUG_DO_NOT_HEAL (route to dev-fix) · QUARANTINE_CANDIDATE (flaky, route to flaky-triage) · BLOCKED (no evidence artifact, or no stable locator target: route to specialist-testid-inserter).

Red Flags

"the assertion was too strict anyway" · "the product changed so update the expected value" · "just add retries so it goes green" — do not heal with these rationalizations. All three are REAL_BUG_DO_NOT_HEAL or QUARANTINE_CANDIDATE in disguise, never HEALED.

Frequently asked questions

What does the Quality Engineering Test Healing AI skill do?

Why use Quality Engineering Test Healing on TypingMind?

Because you install it once and use it with any model. Quality Engineering Test Healing 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 Quality Engineering Test Healing in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/HoangNguyen0403/agent-skills-standard/tree/develop/.agents/skills/quality-engineering/quality-engineering-test-healing. 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 Quality Engineering Test Healing?

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 Quality Engineering Test Healing?

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

Is the Quality Engineering Test Healing AI skill free?

Yes. It is published on GitHub by HoangNguyen0403 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.
