Tutorials, deep dives, and practical guides on building production AI systems with ElsiumAI.
Policy Simulation: terraform plan for AI governance
A security rule nobody dares enable protects nothing. Replay a candidate policy over recorded ExecutionProofs and see which runs it would have blocked — the same rule blocks 100% of traffic or 3% of it depending on one option.
ElsiumAI 0.19.0: Information-Flow Control and the AI-BOM
Taint labels that travel with the data and are checked at every sink, the lethalTrifectaRule() that survives a successful prompt injection, and a signed manifest of an agent’s composition with a CI drift gate.
ElsiumAI 0.16.0: The Critical Five — Fluent VAG, Pause/Resume, and Auto-Replay
Fluent withVerifier() on the agent, runResumable() + resume() across restarts, auto-record + agent.replayFrom(), auto-approval gates for destructive tools, and a complete agent_end stream wrap-up.
ElsiumAI 0.15.0: Cryptographic Receipts, Capability Tokens, and Time-Travel Replay
An Ed25519 crypto foundation, OAuth-style capability tokens with delegation and revocation, typed tool call streams, cost-aware cascade routing, tool contracts, durable askHuman, and time-travel replayFrom.
End-to-End AI Agent Testing in TypeScript: Multi-Turn, Red Team, and CI
Multi-turn conversation testing, adversarial red teaming with 44 attack probes, tool call assertions, agent metrics, and CI reporters. Open-source, TypeScript-first, no SaaS required.
Read article →ElsiumAI 0.10.0: Agentic Security, Red Teaming, and Compliance Reporting
Five new security primitives (agent identity, runtime policies, memory integrity, MCP trust, compliance reporting) plus adversarial red teaming, multi-turn testing, and CI reporters.
Read article →ElsiumAI 0.9.0: Dev Studio, AI Proxy, Structured Extraction, and Enterprise Audit
The biggest release yet. Local observability dashboard, zero-code proxy for any language, one-line typed extraction, eval datasets, and enterprise audit sinks.
Read article →Your AI Agent Just Deleted a Database, Leaked an API Key, and Lost Half a Response
Three production AI failures — stream drops, secret leaks, and uncontrolled agent actions — and the three safety layers that prevent them.
Read article →Your AI App Works — Until Your Provider Goes Down. Then What?
Multi-provider failover with tamper-proof audit trails. Hash-chained compliance logging, circuit breakers, and 1.1M events/sec throughput.
Read article →An AI Agent Wiped a Production Database. 2.5 Years of Data Gone.
An AI coding agent ran terraform destroy on a production database. How approval gates and human-in-the-loop checkpoints prevent catastrophic agent actions.
Read article →Why Your AI Agent Needs Guardrails, Not Hope
Your agent deleted production files. Your human-in-the-loop approved it. Why structural guardrails, circuit breakers, and audit trails matter more than prompts.
Read article →Building an AI Gateway with ElsiumAI
Route requests across multiple LLM providers, cache responses, enforce budgets, and get unified observability — all in under 50 lines of TypeScript.
