✅ AI Code Verification Gate

by JustHandled Labs

$19

or 95 cr

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."

Paste a DNS zone file or dig/nslookup output.

💳 Stripe Webhook & Checkout Doctor

by JustHandled Labs

$25

🛡️ Ad Copy Policy Linter

by JustHandled Labs

$6/mo

Check ad copy for the editorial issues that get Google and Meta ads disapproved, before you submit. Flags all-caps words, gimmicky punctuation (!!, ??), prohibited and hype words, Meta's banned personal-attribute framing ("Are you over 40?"), absolute or unsubstantiated claims, ad-field length overflow, and trademark-term risk. The word lists and field limits are editable, so you can tune it to your accounts.

Maintain 100% uptime with an automated LLM fallback chain that routes from high-tier APIs to local models.

⚔️ Guardrail Fallback Linter

by JustHandled Labs

$12

or 60 cr

Find the LLM integration code that breaks when a model blocks a response or falls back to a different model. Flags calls with no try/except or refusal branch, responses used or parsed with no guard for a blocked or empty answer, and hardcoded model ids with no fallback handling. Built for the Fable 5 era, where a high-risk call is blocked and silently falls back to Opus 4.8.

These are the spoofing tricks and display bugs you cannot catch by reading.
