code context engineering

by Roy Yuen

$7

A high-precision pre-coding gate that detects conflicting requirements and prevents agents from making wrong assumptions.

Enforce human-AI alignment and ownership through structured collaboration checkpoints and real-time syncratude scoring.

agent to agent handoff

by Roy Yuen

$5

Standardize agent collaboration with high-density mission packets, strict authority boundaries, and return contracts.

skill auditor

by Matthew King

$5

Audit, score, and improve your AI agent skills for higher quality, lower token costs, better reliability, and marketplace success. Get actionable recommendations for prompts, instructions, tool usage, error handling, and user experience.

Bug Reproduction Kit Builder for AI Coding Agents

by Shandra

$9.99

Turn vague bug reports into structured reproduction kits, diagnostic plans, and precise AI coding prompts.

📝 Prompt Template Linter

by JustHandled Labs

$12

Lint a prompt template for the issues that cause injection and flaky output. Flags untrusted variables interpolated straight into the instructions (the injection surface), placeholders that are never provided or never used, contradictory instructions, a missing output-format spec where the result is parsed, unbounded context interpolation, and leftover placeholders. It detects problems; it does not write prompts.

weekly cowork system auditor

by LocoLoboZ

$7

A structured governance auditor to optimize AI project instructions, clean up context, and manage workspace health.

✍️ AI Prompt Auditor

by Martin Gunderman

$7

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

Architectural strategist that converts flat prompts into structured, multi-file ChatGPT Skill blueprints.

Custom GPT to Agent Skill Converter

by Shandra

$5

Converts Custom GPT instructions, prompt systems, and agent ideas into structured, premium SKILL.md files for AI agent marketplaces.

AI Agent Self Improvement Memory Auditor

by Shandra

$50

Audits AI agent failures and converts recurring mistakes into durable rules, anti-patterns, regression tests, memory candidates, and improved SKILL.md sections.

Optimization Loop

by Martin Gunderman

$19

Autonomous loop that iteratively modifies, evaluates, and selects the best version of any text resource — skills, prompts, or campaigns — using a modify-measure-keep/discard cycle.

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.

Autoresearch Optimizer

by PubsProToolkit

$5

An iterative agent loop that optimizes any prompt, config, or artifact by making one change at a time, scoring it against a metric, and keeping only the winners.

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

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

Architect reusable AI behavior presets with rigorous rules, activation phrases, and defined output structures.
