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.

Domscribe is an open-source bundler plugin that solves a concrete, frustrating gap in AI-assisted frontend development: agents like Claude and Cursor are great at editing source files, but they have no way to trace which file owns a given rendered element. Domscribe assigns stable IDs to every DOM element at build time and generates a manifest mapping each element to its exact source file, component tree, props, and state. AI coding agents connect via MCP to query any live node in the browser — or click elements in a visual overlay to pass targeted UI context directly into the agent's tool call. The implementation is clean. All debug metadata is stripped at production build time, so there's zero runtime overhead. The manifest only ships in development, keeping bundle sizes clean. It supports React, Vue, Next.js, Nuxt, and all major bundlers: Vite, Webpack, and Turbopack. The MCP server can be pointed at any agent — Claude Code, Cursor, Windsurf, or raw Claude API via any compatible client. This is a genuinely practical tool for teams doing agentic UI work. The bidirectional bridge — source-to-DOM *and* DOM-to-source — means agents no longer need to guess which component renders what. It's MIT licensed, fully local, and has no cloud dependency. A small but meaningful infrastructure piece for the emerging agentic frontend workflow.
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.”
“This fills a real gap I've been hitting weekly. When I tell Claude to 'fix the button in the header,' it has no idea which file that button lives in. Domscribe gives agents ground truth about the rendered DOM — it's the missing link for serious agentic frontend work.”
“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.”
“Right now this is very early — 0 production deployments documented, minimal community adoption. The MCP spec is also still evolving fast, which means integrations could break. Worth watching but I'd wait for a v1 with more real-world usage before betting a production workflow on it.”
“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.”
“Source maps were table stakes for debugging JavaScript. DOM-to-source maps will become table stakes for agentic UI development. Domscribe is early infrastructure for a world where agents refactor entire UIs from a single natural language instruction. The teams building this kind of tooling now will define the standard.”
“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.”
“Designers working with component libraries have always hated the 'where does this button live' problem. Domscribe with the visual overlay mode means I can click any element in a running app and immediately send its exact component context to an agent. That's a qualitatively better workflow for design system work.”
