What Verification & Quality Assurance does

The Verification & Quality Assurance skill provides a robust framework for maintaining code quality and correctness through a series of automated processes. At its core, the skill features a truth scoring system that delivers real-time reliability metrics on a scale from 0.0 to 1.0. This allows developers to assess the reliability of their code, agents, and tasks effectively. By implementing verification checks, the skill automates the validation of code correctness, security, and adherence to best practices, ensuring that only high-quality code is deployed.

One of the standout features is the automatic rollback mechanism that reverts changes that do not meet the established verification threshold (default set at 0.95). This ensures that any failed modifications can be quickly undone, minimizing disruption to the development process. Additionally, the skill provides comprehensive quality metrics, offering statistical analyses that include trends, confidence intervals, and tracking for ongoing improvements. This data-driven approach helps teams to pinpoint areas needing attention and fosters a culture of continuous quality enhancement.

Integration with CI/CD pipelines is seamless, allowing teams to export verification results and incorporate them into their existing workflows. Real-time monitoring capabilities, including live dashboards, provide ongoing visibility into the verification status, making it easier for teams to stay informed about the quality of their codebase. Developers and teams focused on maintaining high standards in their code will find this skill particularly beneficial, as it automates many of the tedious aspects of quality assurance while providing actionable insights into their development practices.

When to use it

Use this skill when you need to automate code verification and maintain high-quality standards in your projects, especially in CI/CD workflows.

When not to use it

This skill may not be suitable for projects that do not require rigorous quality assurance or for teams that prefer manual verification processes.

What you can build with it

Automated Code Review

Integrate the skill into your CI/CD pipeline to automate code reviews and ensure quality before deployment.

Real-time Monitoring

Utilize the live dashboard feature to monitor code quality metrics in real-time during development.

Rollback Failed Changes

Quickly revert to the last stable version of your codebase when a verification check fails.

Verification & Quality Assurance Skill

What This Skill Does

This skill provides a comprehensive verification and quality assurance system that ensures code quality and correctness through:

  • Truth Scoring: Real-time reliability metrics (0.0-1.0 scale) for code, agents, and tasks
  • Verification Checks: Automated code correctness, security, and best practices validation
  • Automatic Rollback: Instant reversion of changes that fail verification (default threshold: 0.95)
  • Quality Metrics: Statistical analysis with trends, confidence intervals, and improvement tracking
  • CI/CD Integration: Export capabilities for continuous integration pipelines
  • Real-time Monitoring: Live dashboards and watch modes for ongoing verification

Shipped vs. aspirational. The concrete, in-CI verification stack — the 6 regression-guard jobs + the witness manifest + the tool-discoverability audit — is real and runs on every push. The truth-scoring / auto-rollback / WebSocket-dashboard surface described later in this doc is partly shipped (ruflo verify runs the witness checks) and partly design — treat the "CI Guards" section below as the authoritative current state.

CI Guards — what's actually shipped (current state)

Ruflo's regression protection is three layers, all gated before publish. Authoritative reference: verification/README.md.

Run the guards locally

# Tool-description discoverability audit (ADR-112)
node scripts/audit-tool-descriptions.mjs                       # fails if any baseline count rises
node scripts/audit-tool-descriptions.mjs --update-baseline     # lock the new floor after a fix lands

# Temporal history

node plugins/ruflo-core/scripts/witness/history.mjs --history verification/macos/history.jsonl regressions

Adding a new guard

  1. Behavioral smoke → write plugins/ruflo-core/scripts/test-<name>.mjs. Pattern: static dist-scan first (fast, always completes), behavioral probe second with an internal timeout + a process-level watchdog so CI never hangs. Add a step to the relevant job in v3-ci.yml.
  2. Static gate with a baseline → write scripts/audit-<name>.mjs that scans, counts violations, and fails if the count exceeds a monotone-decreasing baseline in verification/<name>-baseline.json. Support --update-baseline. Add a CI job; wire it into witness-verify needs[] if it should gate publish.
  3. Documented-fix marker → append { id, desc, file, marker } to verification/witness-fixes.json, run node scripts/regen-witness.mjs. The marker must be a substring the fix specifically creates (not a generic pattern like 'function').

Prerequisites

  • Ruflo installed (npx ruflo@alpha)

Troubleshooting

Common Issues

Low Truth Scores:

# Get detailed breakdown

# Check specific criteria
npx ruflo@alpha verify check --verbose

# View agent-specific issues
npx ruflo@alpha truth --agent <agent-name> --format json

Rollback Failures:

# Check git status
git status

# View rollback history
npx ruflo@alpha verify rollback --history

# Manual rollback
git reset --hard HEAD~1

Verification Timeouts:

# Increase timeout
npx ruflo@alpha verify check --timeout 60s

# Verify in batches
npx ruflo@alpha verify batch --batch-size 10

Exit Codes

Verification commands return standard exit codes:

  • 0: Verification passed (score ≥ threshold)
  • 1: Verification failed (score < threshold)
  • 2: Error during verification (invalid input, system error)

Related Commands

  • npx ruflo@alpha pair - Collaborative development with verification
  • npx ruflo@alpha train - Training with verification feedback
  • npx ruflo@alpha swarm - Multi-agent coordination with quality checks
  • npx ruflo@alpha report - Generate comprehensive project reports

Best Practices

  1. Set Appropriate Thresholds: Use 0.99 for critical code, 0.95 for standard, 0.90 for experimental
  2. Enable Auto-rollback: Prevent bad code from persisting
  3. Monitor Trends: Track improvement over time, not just current scores
  4. Integrate with CI/CD: Make verification part of your pipeline
  5. Use Watch Mode: Get immediate feedback during development
  6. Export Metrics: Track quality metrics in your monitoring system
  7. Review Rollbacks: Understand why changes were rejected
  8. Train Agents: Use verification feedback to improve agent performance
