Q: How do I install risk-based-testing?

Run npx skills add https://github.com/proffesor-for-testing/agentic-qe --skill risk-based-testing in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/risk-based-testing/ (personal) or .claude/skills/risk-based-testing/ (project).

Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/proffesor-for-testing/agentic-qe --skill risk-based-testing

01
Install
Run the command in your project. The CLI asks which agents to install for.
02
Describe the task
Ask your agent for something this skill covers. It loads risk-based-testing automatically when relevant.
03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

Risk-Based Testing

<default_to_action> When planning tests or allocating testing resources:

IDENTIFY risks per component (use 1-5 scale for probability and impact)
PRIORITIZE: Critical (20+) → High (12-19) → Medium (6-11) → Low (1-5)
ALLOCATE effort: 60% critical, 25% high, 10% medium, 5% low
REASSESS continuously: Production incidents raise risk; stable code lowers it </default_to_action>

Quick Reference Card

When to Use

Planning sprint/release test strategy
Deciding what to automate first
Allocating limited testing time
Justifying test coverage decisions

Effort Allocation by Risk Score

Score	Priority	Effort	Action
20-25	Critical	60%	Comprehensive testing, multiple techniques
12-19	High	25%	Thorough testing, automation priority
6-11	Medium	10%	Standard testing, basic automation
1-5	Low	5%	Smoke test, exploratory only

Apply Test Depth by Risk

await Task("Risk-Based Test Generation", {
  critical: {
    features: ['checkout', 'payment'],
    depth: 'comprehensive',
    techniques: ['unit', 'integration', 'e2e', 'performance', 'security']
  },
  high: {
    features: ['auth', 'user-profile'],
    depth: 'thorough',
    techniques: ['unit', 'integration', 'e2e']
  },
  medium: {
    features: ['search', 'notifications'],
    depth: 'standard',
    techniques: ['unit', 'integration']
  },
  low: {
    features: ['admin-panel', 'settings'],
    depth: 'smoke',
    techniques: ['smoke-tests']
  }
}, "qe-test-generator");

Step 3: Reassess Dynamically

// Production incident increases risk
await Task("Update Risk Score", {
  feature: 'search',
  event: 'production-incident',
  previousRisk: 9,
  newProbability: 5,  // Increased due to incident
  newRisk: 15         // Now HIGH priority
}, "qe-regression-risk-analyzer");

ML-Enhanced Risk Analysis

// Agent predicts risk using historical data
const riskAnalysis = await Task("ML Risk Analysis", {
  codeChanges: changedFiles,
  historicalBugs: bugDatabase,
  prediction: {
    model: 'gradient-boosting',
    factors: ['complexity', 'change-frequency', 'author-experience', 'file-age']
  }
}, "qe-regression-risk-analyzer");

// Output: 95% accuracy risk prediction per file

Remember

With Agents: Agents calculate risk using ML on historical data, select risk-appropriate tests, and adjust scores from production feedback. Use agents to maintain dynamic risk profiles at scale.
