A systematic 4-phase debugging framework to find root causes, eliminate flaky tests, and prevent regressions.

Automated risk classification and regression checking to stop AI agents from breaking your codebase.

🧪 Webapp Tester

by JustHandled Labs

$15

Run real Playwright E2E tests on your web app: login, checkout, and form flows across desktop and mobile viewports, with screenshots, traces, and console logs captured on every failure. Catches broken flows and UI regressions before release, and tells you the likely fix, not just that something broke.

✅ AI Code Verification Gate

by JustHandled Labs

$19

One-line summary description Stop your agent from claiming "done" before it's proven. A verification gate that classifies each change by risk (payment, auth, database, user-facing), picks the tests that actually cover it, demands evidence, maps regression risk, and outputs an honest pass/fail report. Turns "looks good to me" into "here's what I ran, and here's what's still unverified."

♿ a11y Regression Test Generator

by JustHandled Labs

$15

Generate runnable accessibility regression tests, not just a findings report. Detects a11y issues, missing alt text, unlabeled controls, keyboard and focus gaps, in your routes, components, or HTML, then emits Playwright + axe-core spec files with targeted assertions and remediation tickets for each. Previews the tests first and writes them only on your confirmation.

⚡ Perf Budget Auditor

by JustHandled Labs

$12

Audit your frontend build against a performance budget and catch size regressions before you ship. Flags total bundle over budget, initial bundle over budget, individual chunks over a threshold, oversized image assets, source maps shipped to production, and large unminified JavaScript. Reads a webpack or Vite-style stats.json plus a perf-budget.json you control.

AI Feature Eval Writer

by PubsProToolkit

Free

Design and write the eval suite for your LLM-powered feature — the metrics that match your failure modes, a golden dataset plan with starter cases, anchored rubrics, LLM-as-judge prompts with the known bias mitigations, and pass/fail gates wired for CI.

AI Agent QA & Failure Testing Specialist

by Shandra

$15

Tests AI agents, prompts, and agent skills against edge cases, unsafe behavior, output failures, permission risks, escalation gaps, memory leaks, and marketplace-quality weaknesses.
