WIO Testing Workflow

A five-mode testing workflow that finds high-value test candidates, writes and reviews focused tests, generates adversarial workloads, and diagnoses test-suite health.

Dev & CodingIntermediate★ 155⑂ 24AI score 9/10Last updated: Jul 31, 2026

What it does

WIO bundles five testing modes into one skill:

  • scan – read-only discovery and ranking of the highest-value test candidates by impact, fault mechanism and cost
  • test – pick one candidate, choose test level / oracle / fixtures, write one focused test, validate with the smallest command, then review
  • workload – generate a realistic, adversarial workload that adds a genuinely new failure surface, oracle or state model (explicitly rejects thin wrappers around existing runners)
  • review – return KEEP, REDO or REMOVE with falsification evidence
  • doctor – read-only suite health scan for flakes, weak assertions, over-mocking, shared state, slow CI

Every mode defines the inspection order, which strategy references to load, and a fixed Markdown output template — plus hard rules such as "never test just to raise coverage" and "never mock away the boundary that creates the real risk".

Who it's for

  • Developers who know they need more tests but not where to start
  • Teams with high coverage that still ships regressions
  • Leads who want a consistent bar for "is this test worth keeping?" in code review
  • QA/platform engineers designing session workloads, E2E journeys or load profiles

Examples

  1. $wio scan src/payments – ranked candidate list plus the single best next test and what to avoid
  2. $wio test retry idempotency – writes one test that would catch duplicate charges, runs the narrowest validation command, then issues a KEEP/REDO/REMOVE verdict
  3. $wio doctor – graded suite report with P0–P3 concerns, evidence files and quick wins

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the plugins/wio/skills/wio folder from the GitHub repo workersio/skills into my ~/.claude/skills/wio/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/workersio/skills.git /tmp/wio-skills && mkdir -p ~/.claude/skills && cp -r /tmp/wio-skills/plugins/wio/skills/wio ~/.claude/skills/wio

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/workersio/skills.git /tmp/wio-skills
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy the skill, including its references/ and scripts/ folders: cp -r /tmp/wio-skills/plugins/wio/skills/wio ~/.claude/skills/wio
  5. Verify with ls ~/.claude/skills/wio — you should see SKILL.md, references/ and scripts/.
  6. Restart Claude Code, then trigger it with $wio scan or a prompt like "what should I test next?".
  7. Optional: to use the subagents, copy the files from plugins/wio/agents/ into your project's .claude/agents/ — installing the skill does not create them automatically.
