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.

Devin for Terminal
Local CLI coding agent that keeps working when you close your laptop

Cognition's Devin for Terminal brings the full autonomous coding power of Devin to your command line. Unlike the browser-based Devin interface, the Terminal version lets you trigger complex engineering tasks from your CLI and continue working — or close your laptop entirely — while Devin executes in the cloud in a persistent session. The key innovation is bidirectional handoff: you initiate locally, Devin Cloud takes over with a persistent execution environment that survives network drops, sleep cycles, and machine switches. This bridges the "last mile" problem of autonomous coding tools — the frustrating requirement to stay connected while a long job runs. Launched April 29, 2026, Devin for Terminal is free to use and signals Cognition's push toward deeper developer workflow integration beyond browser-only interfaces. The clear implication: the future of coding agents isn't a tab you keep open, it's infrastructure that runs in the background.
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.”
“The 'keep working when you close your laptop' pitch is exactly right. I've lost countless Devin sessions to network hiccups. Persistent cloud-backed execution from my terminal is the architecture I've wanted since day one. This is how async development should 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.”
“Devin's benchmarks have always been impressive; real-world results sometimes less so. A terminal wrapper doesn't change the underlying model's limitations — it just makes them more convenient to encounter. And Cognition still hasn't fully addressed cost transparency on longer sessions.”
“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.”
“Devin for Terminal is a preview of where all coding tools are heading: invisible infrastructure that executes while you're away. The terminal is the right interface — it meets developers where they already live. Expect every major coding agent to have a persistent CLI within 6 months.”
“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.”
“Terminal tools aren't for most creators — but for technical creatives who build their own tools, persistent agent execution is a genuine unlock. Kick off a refactoring job, go design something, come back to a finished PR. That's a workflow shift.”
