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.

| Layer | What | CI job(s) in .github/workflows/v3-ci.yml | ADR | |---|---|---|---| | 1 — install/behavioral smoke | Exercise user-visible failure modes against a real build | smoke-install-no-bsqlite (npm install on platforms w/o prebuilds), plugin-hooks-smoke (#1859/#1862 — hook flag parsing), mcp-protocol-smoke (#1874 — HTTP MCP wire format), memory-import-smoke (#1883/#1884 — WSL path + key sanitization), mcp-roundtrip-smoke (#1889 paired-tool round-trip + #1863 cli-no-crash + ADR-095 G2 consensus-transport) | ADR-102 | | 1 — discoverability gate | Every MCP tool description must answer "use this over native when?" | tool-descriptions-audit — scripts/audit-tool-descriptions.mjs, baseline at verification/mcp-tool-baseline.json (monotone-decreasing: noGuidance / tooShort / duplicates) | ADR-112 | | 2 — cryptographic witness | Every documented fix's load-bearing marker must still be present in dist; Ed25519-signed, per-OS bundles | witness-verify (ubuntu/macos/windows) — plugins/ruflo-core/scripts/witness/verify.mjs against verification/<os>/manifest.md.json | ADR-103 | | 3 — temporal history | When was a regression introduced | verification/<os>/history.jsonl + history.mjs (summary / regressions / timeline) | ADR-103 |

Run the guards locally

bash
# 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

# Behavioral smokes (each builds what it needs; safe to run individually)
node plugins/ruflo-core/scripts/test-hooks.mjs "node $PWD/v3/@claude-flow/cli/bin/cli.js"
node plugins/ruflo-core/scripts/test-mcp-protocol.mjs
node plugins/ruflo-core/scripts/test-memory-import.mjs
node plugins/ruflo-core/scripts/test-mcp-roundtrips.mjs        # #1889 paired-tool round-trip
node plugins/ruflo-core/scripts/test-cli-no-crash.mjs          # #1863 unhandled-exception class
node plugins/ruflo-core/scripts/test-consensus-transport.mjs   # ADR-095 G2 consensus transport

# Witness manifest — regenerate + verify
node scripts/regen-witness.mjs
node plugins/ruflo-core/scripts/witness/verify.mjs --manifest verification/macos/manifest.md.json

# Temporal history
node plugins/ruflo-core/scripts/witness/history.mjs --history verification/macos/history.jsonl summary
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)
• Git repository (for rollback features)
• Node.js 18+ (for dashboard features)
• @noble/ed25519 (for the witness verifier — a single runtime dep, npm i @noble/ed25519)

# View current truth scores
npx ruflo@alpha truth

# Run verification check
npx ruflo@alpha verify check

# Verify specific file with custom threshold
npx ruflo@alpha verify check --file src/app.js --threshold 0.98

# Rollback last failed verification
npx ruflo@alpha verify rollback --last-good

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

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

bash
# Check git status
git status

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

# Manual rollback
git reset --hard HEAD~1

Verification Timeouts:

bash
# 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
