✍️ AI Prompt Auditor

by Martin Gunderman

$7

Systematic audit for AI prompts to detect security flaws, bias, and cost-inefficiencies with auto-optimization.

💰 AI Cost Optimizer

by Martin Gunderman

$7

An advanced FinOps engine to analyze AI usage, optimize token spend, and reduce LLM costs by up to 60%.

🧰 Tool Schema Linter

by JustHandled Labs

$12

Lint the function-calling tool definitions your agent exposes. Flags tools with no description, parameters missing a description or a type, overlapping or near-duplicate tools, too many tools for reliable selection, an unsafe tool exposed without a guard, required parameters missing from the schema, and free-form parameters that should be bounded with an enum. Cleaner tool schemas mean an agent that picks the right tool.

🩺 llms.txt Doctor

by JustHandled Labs

$9

Generate an llms.txt for your site and validate an existing one against the spec. The generator turns your sitemap.xml or docs folder into a clean, sectioned llms.txt with one-line descriptions. The validator flags a missing H1 title, a missing summary blockquote, malformed link entries, links with no description, relative URLs that should be absolute, and a referenced llms-full.txt that is not present.

Your headless Ollama box crashes at 3am and you find out hours later. OllamaWatch pings your Telegram the instant a model dies, the GPU runs out of memory, or the API hangs — with a fix hint in every alert. One Python file, no SaaS, no dashboards.

Battle-tested prompting patterns to eliminate LLM output drift. Sandwich structure, few-shot examples, history limits, retry, and token caps — 6 composable layers for production-grade agent reliability.

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

LLM Eval Framework Builder

by Arnstein Larsen

$17

You changed the prompt, tried four inputs, it looked better, you shipped — and three days later support tickets say outputs are worse for an entire class of inputs you didn't test

nex dashscope qwen setup

by Nex AI

$5

Generate a production-ready Python client for Alibaba Qwen models with text, vision, and reasoning tag filtering.

nex ai content generator

by Nex AI

$7

High-reliability Dutch content engine with a Claude-Gemini-Qwen fallback chain and template safeties.

🔁 Model Migration Checker

by JustHandled Labs

$6/mo

Find the model-version coupling that breaks when you swap LLMs. Flags hardcoded model names and versions, deprecated or renamed parameters (the max_tokens to max_completion_tokens class of change), hardcoded token and context-window limits, response-format parsing tied to one model's output, tool-schema format coupling between providers, and hardcoded per-token cost constants. The patterns load from an editable model-rules table you update as new models ship.

⚔️ 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.

nex telegram bot deploy

by Nex AI

$7

Deploy production-grade, AI-powered Telegram bots to Raspberry Pi with automated server hardening and scheduled jobs.

A production-ready Python integration for Gemini using a unified AIProvider interface for easy model swapping.

Token Budget Officer

by PubsProToolkit

$19

Cost-aware execution planning for AI agents — estimate cost-vs-value before expensive steps, propose cheaper paths (cache, summarize once, downshift models), and track spend against a session budget with a PROCEED / OPTIMIZE / DEFER verdict.

nex claude api integration

by Nex AI

$7

Production-ready Claude API integration with dual-model routing, token tracking, and resilient retry logic.

Professional AI Engine Optimization (AEO) audit tool that delivers a 100-point score and ready-to-code fix prompts.

Prompt Engineering Specialist

by Arnstein Larsen

$8.99

Production prompts grow by accretion — every failure gets another appended rule until the prompt is two thousand words of contradictions that the model navigates unpredictably

Paste any AI output. Get the production-ready prompt that made it.

Convert loose prompt sets into structured, target-ready records with variables, contracts, and eval cases.

AI product type routing, discovery framework, LLM app design (Prompt/RAG/Agent), metrics, ethics.
