Hardens AI prompts and agent workflows against logic errors, tool-misuse, and prompt injection.

Dependency Upgrade & Framework Migration Planner for AI Coding Agents

by Shandra

$55

Plans safe dependency upgrades and framework migrations for legacy applications with risk analysis, compatibility mapping, test planning, rollback strategy, and phased AI coding prompts.

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.

RAG System Designer

by Arnstein Larsen

$9.99

Every RAG tutorial shows the same pipeline; almost none of it survives contact with your actual corpus

Model selection matrix (MJ/Flux/SD), composition rules, 3-level quality gates, 10 style recipes.

agent ready api

by Mark Lavercombe

Free

Score and optimize any website for AI agent-readability using the Agent Ready REST API.

🛡️ 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.

Evaluate third-party agent skills for command injection, prompt injection, and data exfiltration before installation.

Citation Guard

by PubsProToolkit

$12/mo

Stop your agent citing papers that don't exist. Verifies every reference against live PubMed & Crossref — flags fabricated, mismatched, and retracted citations.

🗂️ Model Inventory Auditor

by JustHandled Labs

$13

Inventory every LLM model and provider your code depends on, the AI bill of materials, and flag the dependency risk. It lists each provider, model, and where it's used, then flags hardcoded model ids, single-provider dependency with no alternative, the same model referenced by different ids, model ids with no config or env indirection, and providers pinned in your manifests. Recognizes OpenAI, Anthropic, Google Gemini, and more from an editable list.

Run a buyer-readiness check before publishing an AI agent skill package.

api key vault

by Roy Yuen

$7

Secure encrypted secret management with automated health checks, expiration tracking, and rotation reminders.

Turns open-ended AI chats into guided, interactive menu systems for structured task navigation.

Failure Mode Choreographer

by Al1as

$19.99

Architect designed system degradation and choreographed failure sequences to prevent chaotic breakdowns.

apiosk

by Olivier Brinkman

Free

AI Prompt Injection Defense Shield & LLM Jailbreak Security Auditor Code Review Agent

by Brandon DeVries

Free

Stop leaving your AI startup exposed to malicious users trying to steal your proprietary system prompts or bypass your paywalls. The AI Prompt Injection Defense Shield is an automated code review agent that deeply analyzes your Next.js or Python backend, instantly detecting insecure LLM input fields, un-sanitized API data streams, and weak prompt boundaries. By automatically generating the exact copy-paste code patches required to harden your AI wrapper against the latest OWASP top 10 LLM vulnerabilities, this skill allows solo developers and indie hackers to confidently launch their SaaS without the fear of massive, unexpected API billing spikes or catastrophic data leaks.

AI Automation QA & UAT Pack

by Arnstein Larsen

$5

A QA lead for AI automations and agent systems — turns a delivery into acceptance criteria, UAT scripts, a non-determinism test plan, a failure-mode matrix, and a client-ready sign-off pack, or audits an existing automation for the gaps that cause silent production failures.

llms.txt Generator

by PubsProToolkit

$12

Generate a spec-compliant llms.txt (and optional llms-full.txt) for your site or repo so AI agents and crawlers can navigate it. Curates the pages that matter, writes the exact llmstxt.org structure — single H1, blockquote summary, and link sections in the precise format agents parse — then validates the format and tells you where to put it. The honest version: a low-cost, machine-readable surface for the agentic web, not an overhyped SEO trick.

Convert a repeatable workflow into a reusable agent skill or staged skillchain candidate.

Intelligently audit your repo and workflow to recommend, install, or create custom AI agent skills.
