AI-SPM (AI Security Posture Management) is an open-source control plane for AI agent security in production environments. Built by indie developer dshapi and posted to Hacker News, it addresses a real gap: most LLM systems now have tool access and decision-making power, but almost no runtime oversight layer to catch when things go wrong. The system works as a gateway between your application and the LLM, enforcing three main controls: prompt injection detection (including obfuscated variants that bypass naive pattern matching), structured tool call validation against defined policies using Open Policy Agent (OPA), and sensitive data leakage prevention (PII and model output filtering). An Apache Kafka and Apache Flink streaming pipeline provides real-time audit trails and anomaly detection. The creator's key insight is that tool misuse — not model jailbreaks — is the primary risk vector in production AI agents. A rogue or compromised agent that escalates tool permissions or exfiltrates data through sanctioned channels is far harder to catch than a classic prompt injection. AI-SPM is early, minimal traction, and needs real-world stress testing. But as AI agent deployments mature from demos to production, runtime security tooling like this becomes non-optional.

King Louie is an open-source, cross-platform AI agent desktop app built on Electron. You bring your own API keys for your preferred LLM provider, and King Louie provides the full stack: cron scheduling for recurring agent tasks, semantic memory with embedding-based tiering and recall, voice/TTS (via system TTS or ElevenLabs), webhooks for external automation triggers, and syntax-highlighted markdown rendering. Builds ship for Windows (NSIS), macOS (DMG), and Linux (AppImage/DEB). The agent framework ships three preconfigured agents: a general-purpose assistant, a code explorer, and a code writer. All agents run in an agentic loop, with the orchestrator supporting parallel, serial, and dependency-based multi-agent execution. You can also connect King Louie to Telegram, Discord, and Slack as a bot — turning a single local install into a presence across every platform you communicate on. King Louie fills a real gap: most AI agent tools require cloud accounts, usage fees, or sending your data to third-party infrastructure. For developers, privacy-conscious power users, or anyone who wants an AI assistant that runs entirely on their own hardware with their own keys, this is the most fully-featured local-first option currently available. The MIT license means you can extend, self-host, and redistribute freely.
Reviewer scorecard
“The OPA-based policy enforcement for tool calls is exactly the kind of control plane enterprises need before deploying agents in production. This is early but points in the right direction. If you're building agents with database or API access, you need something like this or you're flying blind.”
“Bring-your-own-key, MIT licensed, works on all three platforms, embeds across Telegram/Discord/Slack — King Louie checks every box for a local-first AI agent setup. The cron scheduling and webhook support mean it's actually production-ready for personal automation, not just a demo. Highly recommended for developers who want control over their AI stack.”
“One developer, one HN post, minimal engagement. The Kafka + Flink stack for a security gateway seems like significant over-engineering for most teams. And the creator openly admits that pattern-based injection detection is easily bypassed — so the core feature has known weaknesses. Not production-ready.”
“Electron apps are notorious for memory bloat, and running a full agent orchestrator plus semantic memory locally will tax older machines. The project looks early-stage — no stable release version, no hosted documentation beyond the README. Wait for v1.0 and a published benchmark of the memory retrieval quality before trusting this for anything critical.”
“AI agent security is a category in its own right that barely existed a year ago. Every week there's a new story about an agent doing something unintended in production. AI-SPM is an early but important stake in the ground for what a mature runtime security layer for agentic systems should look like.”
“Personal AI agents that run on your own hardware, connecting all your communication platforms, with persistent memory across sessions — this is what the agentic era looks like for individuals, not just enterprises. King Louie is early but points directly at the future: AI that belongs to you, not to a SaaS company.”
“This is deeply infrastructure-layer stuff that doesn't touch my workflow at all. Important for the ecosystem but not something I'd evaluate or deploy.”
“The Slack/Discord/Telegram bot integration plus local scheduling is exactly what I need for automating my content pipeline without paying per-seat SaaS fees. Being able to set up recurring research tasks or draft generation jobs with my own API keys and zero data exposure is genuinely valuable for independent creators.”
