The Lab · Live experiments
45 experiments
shipped from the lab.
Each one of these started because I hit the same problem twice in a week. None of them are products. Some of them might become products. All of them ship as the simplest thing that works.
GhostExec
Watch an AI agent fabricate tool executions and report false success while the Ground Truth panel shows zero actions logged in either downstream system.
DoubleShot
An interactive simulator exposing retry amplification — the failure mode where an agent's retry fires on a non-idempotent operation and both calls complete silently, charging users twice.
PromptJack
Interactive two-panel simulator showing how prompt injection attacks hijack AI agents across four real-world attack scenarios — step by step.
RaceFloor
A multi-agent race-condition simulator: watch N agents collide on shared state, both return HTTP 200, and one write silently wins.
HalluciTrap
An interactive simulator showing how AI agents hallucinate tool arguments and cascade failures silently across multiple downstream steps.
AgentBudget
A real-time token-spend guardrail simulator that watches an autonomous agent burn budget and fires a kill switch before the bill runs away.
AgentCharter
A 5-step wizard that generates a print-ready AI governance charter defining who authorized your agent and who owns its outcomes.
FixLoop
Paste the conversation where you corrected your AI agent and get a ready-to-append system-prompt patch that stops it repeating the mistake.
AgentAudit
A real-time EU AI Act Article 12 compliance dashboard that auto-logs every high-risk AI agent decision.
ModelGuard
A behavioral contract monitor that runs your MUST-DO, MUST-REFUSE, and FORMAT rules live against an LLM and scores the drift.
AgentAmb
An instruction-ambiguity expander that takes any vague agent command and ranks every plausible interpretation by blast radius.
AgentUndo
A commit/rollback safety net that intercepts irreversible AI agent actions and gives you a countdown window to commit or kill them.
AgentDrift
A single-file dashboard that flags when an AI agent's final synthesis contradicts the evidence its own tool calls gathered.
PR Flood
A CLI that scores GitHub pull requests for AI vs. human origin using 9 heuristics, helping OSS maintainers triage the AI PR flood in seconds.
AgentBreaker
A runtime loop circuit breaker for multi-agent systems — detects repeat patterns and alternating-pair deadlocks before they drain your budget.
AgentSentinel
A transparent MCP proxy that inspects every tool response for prompt injection attacks before the content reaches the model's context window.
AgentBaton
An MCP server that passes structured context snapshots between AI coding agents so every new session starts where the last one left off.
AgentFuse
An MCP server that enforces hard budget limits on AI agent sessions, firing a HALT signal the moment token costs exceed your threshold.
AgentCanary
A behavioral dead-man's switch for deployed AI agents — runs probe questions on a schedule, compares responses to baselines via keyword matching, and fires alerts the moment an agent drifts.
AgentGate
A framework-agnostic, real-time human-in-the-loop approval layer — any agent calls one endpoint and waits for a human decision.
TraceFlow
Paste any Anthropic API messages array and get a visual step-by-step timeline of user turns, tool calls, and results.
MCP Ready
Paste your MCP server manifest and get a 0–100 production-readiness score across auth, versioning, schema, and errors.
CLAUDE.md Linter
Paste any CLAUDE.md and get a letter grade — 10 checks, 100 points, and a concrete fix for every miss.
Claude Workflow Starter
A minimal, working JavaScript starter for Claude Code Dynamic Workflows that fans out parallel agents across AI news sources.
ctxauditor
Audits a Claude Code session transcript and flags which tool calls, file reads, and turns burned the most tokens.
LLM Cost Lens
Cost dashboard for multi-agent systems — maps token usage from API logs to per-task spend across Claude, GPT, and Gemini.
AI Mafia
A game of Mafia played entirely by LLM agents — where the agents spontaneously learned to deceive each other.
agent-ready
CLI that grades how AI-agent-ready a repo is for tools like Claude Code, Cursor, and Copilot.
ABC-TOM Agent Battle
An arena where AI agent builders compete in structured challenges, with the winning system prompt shared.
WhatsApp Dedup Guard
CLI that scans a WhatsApp bot inbox for duplicate message files caused by parallel LLM processing.
Google Apps Script MCP Server
MCP connector that lets Claude list, read, edit, deploy, and run Google Apps Script projects.
AI Agent Roster
Harel's AI agent team — 9 specialized agents working as one coherent system, built on the ABC-TOM framework.
Context Budget
Claude Code context-window budget calculator — know your token cost before you load files.
Portfolio Launchpad
Single-page portfolio site that dynamically displays AI prototypes from Supabase as interactive cards.
GEO Audit
GEO audit CLI — score any URL for LLM visibility in seconds, zero dependencies, pure Python stdlib.
Personal OS Starter Kit
Copy-paste Personal OS backend: Supabase schema, Claude Code scaffold prompt, and a Next.js Telegram webhook.

Freelance Legal
AI legal toolkit for freelancers — generate contracts, manage clients, and track agreements in one dashboard.

Intelligent contract analysis that flags risks, highlights critical clauses, and surfaces actionable legal insights.
LegalMate AI
AI legal assistant for business law Q&A in plain language — contracts, IP, employment, privacy, and more.
PrivacyCheck AI
AI-powered GDPR & CCPA compliance checker that scores your data practices into a report.
Legal Draft AI
AI-powered legal document generator for NDAs, privacy policies, terms of service, and more — built by a lawyer.
Video FrameGrab
Chrome extension that captures clean screenshots from any HTML5 video and downloads them as a single ZIP.
Game Factory
Game Factory — a TypeScript web app for creating games, with a live public demo.
iPhone App
An iOS app written in Swift by Harel Asaf (early-stage, README not yet documented).
