845 AI agents and automations, free to use
A browsable library of agent prompts and automation workflow templates for n8n, Make, and more: search it, filter it, and download the workflow JSON. KOBA42 builds and operates systems like these for real businesses, so every entry here is also a build we can scope.
KOBA42 originals
Copy-paste prompts we wrote from the way we actually build: code review, security, RAG evaluation, project scoping, and web3. No setup, no tools, works in any chatbot.
The Adversarial Code Reviewer
Reviews a diff by trying to break it, not by policing style. For engineers who want failure scenarios with concrete triggers and a minimal fix for each, not a wall of naming nits.
The Security Review Gauntlet
Walks a code change through auth, injection, secrets exposure, and attacker-controlled-input classes, producing an exploit sketch and a minimal fix for each real finding. Includes...
The RAG Evaluator
Generates a groundedness test set from your own documents, then grades retrieval-augmented answers for hallucination and citation accuracy. For teams shipping RAG who need to measu...
The Legacy Codebase Cartographer
Paste unfamiliar code and get a system map: entry points, one traced data flow, the three files that matter most, and the landmines a newcomer will hit. For the engineer who has to...
The Blameless Postmortem Writer
Turns a messy incident timeline into a blameless postmortem: contributing factors instead of a single root cause, what made it hard to detect, and specific action items with owners...
The Claude Code Project Bootstrapper
Interviews you about your repository and produces a CLAUDE.md or agent-rules file: conventions, exact test commands, do-nots, and the architecture the agent must not fight. For any...
The AI Project Scoping Interviewer
An interviewer that walks you through the eight things an AI project must pin down, one question at a time, then hands you a completed scoping brief a builder could estimate from....
The Maintenance-Honest ROI Calculator
An ROI model for automation that forces in the three costs vendors leave out: build, exceptions and rework, and ongoing maintenance. Outputs a break-even and a three-year net, and...
The Vendor Claim Interrogator
Paste an AI vendor's pitch or your demo notes and get the 15 questions that separate a real system from a good demo: who owns the code, how data is handled, what breaks at scale, l...
The AI Readiness Auditor
A conservative self-assessment across four dimensions that actually predict whether an AI build survives production: workflow clarity, data access, human review, and operational ow...
The Prompt Surgeon
Paste a prompt that is underperforming and get a diagnosis against a fixed checklist of failure modes, then a rewritten version with the reasoning shown so you learn the pattern. F...
The System Prompt Hardener
Paste an agent's system prompt and get it red-teamed for prompt injection, role escape, instruction leakage, and tool abuse: concrete attack strings it would try, and a specific ha...
The Agent Team Architect
Describe a job you want a team of AI agents to do and get back the full decomposition: the roles, the handoffs between them, the verification gates, and the failure modes, before y...
The Verifier Pattern Pack
A small pack of copy-paste prompts that make AI output trustworthy the way real review does: one agent builds and lists its load-bearing claims, a second is paid only to refute the...
The Meeting-to-Decisions Compiler
Paste a raw meeting transcript and get back decisions, owners, and deadlines, plus an 'unresolved disagreements' section that most notetakers quietly drop. For anyone who runs meet...
The Follow-Up That Doesn't Grovel
Writes sales and business follow-up emails in an honest, no-hype voice, and kills the desperate 'just circling back' reflex. For anyone who has to nudge a deal without sounding lik...
The Proposal De-Fluffer
Paste a proposal or landing page and it strips the copy to claims plus evidence, then quotes back every sentence that could describe any company. For marketers and founders who wan...
The One-Page Business Case
Turns a messy decision and your scattered context into a one-page business case: the ask, the problem, options considered, the cost of doing nothing, and a recommendation, built to...
The Smart Contract Pre-Audit Runner
A structured first pass over Chialisp or Solidity code that walks the standard exploit classes before you pay for a human audit. For teams who want to catch the obvious holes cheap...
The Tokenomics Sanity Checker
Paste a token model and get back the incentive-collapse and death-spiral scenarios it invites, before you write the whitepaper. For founders pressure-testing a design, not for pump...
The Web3 UX Translator
Rewrites crypto-native flows (wallets, signing, gas, seed phrases) into words a first-time user survives, without hiding the security facts that keep their funds safe. For product...
The Eval Harness Starter
Turns "the new prompt seems better" into a runnable 20-case eval set with explicit pass/fail criteria per case, so you can measure a prompt or model change instead of eyeballing it...
The Few-Shot Example Factory
Generates diverse, edge-case-covering labeled examples for a classification or extraction task, so your few-shot prompt teaches the boundaries, not just the easy middle. For anyone...
The Build vs Buy vs Wait Tribunal
Argues all three positions (build it, buy it, wait) for a proposed AI project as strongly as each deserves, then delivers a verdict that names the single deciding factor. For teams...
The Context Budget Manager
A method for briefing a subagent or LLM: what to include, what to deliberately leave out, and how to demand a structured return so the answer comes back usable. For anyone orchestr...
The Negotiation Prep Second
