Transactional Email Engine

by PubsProToolkit

$59

Scaffold a complete, production-ready transactional email system — verification, password reset, receipts, and notifications — with deliverability hardening, retries, idempotency, and a suppression list.

🌐 i18n Completeness Auditor

by JustHandled Labs

$12

Audit a JavaScript or TypeScript frontend for missing translations and hardcoded UI strings before you ship a new locale. Flags hardcoded JSX text and UI props (title, placeholder, aria-label, label, alt) not wrapped in t(), i18n.t(), or <Trans>; keys present in the default locale but missing from other locale files; keys referenced in code but absent from the locales (the raw dotted keys that leak to users); unused locale keys; and unparseable locale JSON.

⚔️ Guardrail Fallback Linter

by JustHandled Labs

$12

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.

📚 Reference Grounding Checker

by JustHandled Labs

$15

Before an agent acts on a plan, verify that the things it named actually exist. Checks each referenced file path, function or method, import or package, environment variable, and CLI command against your repo, and flags the ones that do not resolve. Catches the hallucinated function and the phantom package before the edit, not after the build breaks. Resolves Python and JavaScript/TypeScript.

An expert architect for building scalable, high-performance React applications with TypeScript and modern best practices.

code review buddy

by Roy Yuen

$5

Structured, severity-aware code reviews focusing on security, bugs, and performance across all major languages.

nex discord oauth pi

by Nex AI

$5

Production-ready Discord Embedded App SDK OAuth handshake for Node/Python backends and TypeScript frontends.

Deep audit of TypeScript codebases for type safety violations, unsafe casts, and runtime-risk anti-patterns.

Complete Next.js & Stripe billing engine with per-seat proration, secure webhooks, and multi-tenant member management.

MCP Server Builder

by PubsProToolkit

$24

Scaffold a secure, spec-compliant MCP server from a description of the tools you want to expose. Sets up the official SDK (TypeScript or Python/FastMCP), defines tools/resources/prompts with strict JSON Schema, wires the right transport (stdio or Streamable HTTP), adds OAuth 2.1 for remote, and hardens against the MCP-specific footguns — prompt injection via tool output, token passthrough, over-broad scopes, command/path/SSRF injection, leaked secrets — before it ships. Returns a runnable skeleton plus a security checklist. Built by someone who's shipped production MCP servers.

🧪 AI Build Sanity Check

by JustHandled Labs

$13

Scan local Python, JavaScript, TypeScript, JSX/TSX, HTML, JSON, and .env files for build markers, returned fake-data terms, swallowed errors, placeholders, route-adjacent canned success, and advisory empty handlers. Read-only findings include rule, severity, file, line, and a plain fix.

🛡️ Model Resilience Linter

by JustHandled Labs

$12

Find the LLM integration code that will not survive a provider being pulled or going down. Flags single-provider lock-in with no alternative, calls with no failover branch, missing timeouts, retries with no limit or backoff, no degraded-mode default, and hardcoded endpoints with no alternate. This is about the model going away, not the model declining.

nex discord activity pi

by Nex AI

$7

Deploy production-ready Discord Activities to a Raspberry Pi with Colyseus multiplayer and Cloudflare Tunneling.

Senior Web App Architect for Coding Agents

by Avesta Agency Australia | Software Engineering Group

$9.99

Messy, insecure, unfixable — that's what AI builds without architecture. This file is the architecture: 10 years of senior judgement on rendering, caching, security and SEO, so your agent builds it right from day one.

Playwright E2E Test Generator

by Timoranjes

$5

Teaches AI coding agents to generate production-quality Playwright end-to-end tests from page analysis, user stories, or existing code. Covers selector strategy, test structure patterns, flakiness prevention, and CI integration — for QA engineers and solo devs tired of AI-generated tests that break on first run.

Build production-grade React Native apps with native primitives, optimized lists, and type-safe navigation.

💸 LLM Cost Leak Linter

by JustHandled Labs

$12

Find the code that quietly runs up your LLM bill: uncapped generations, model calls looping with no limit, an expensive model doing a trivial job, and whole files stuffed into prompts. Read-only, every finding explained in plain English.

Diagnoses NestJS ConfigModule, .env, and Docker/Kubernetes environment failures — finds missing vars and misconfigurations before your app boots.

prisma schema safety architect

by Timoranjes

$10

Teaches AI coding agents to design safe Prisma schemas that prevent data loss, race conditions, N+1 queries, and the dangerous Prisma migration reset. Covers 12 critical anti-patterns (missing indexes

agent rules generator
