What it does
AI agents have no persistent identity every run is anonymous, untraceable, unaccountable. AI Codex fixes this. Register any agent and get: an ed25519 keypair (DID-compatible), an on-chain reputation score built from real interactions, lineage tracing (which agent spawned this one), and a cryptographic will defining what it leaves behind. The identity primitive your multi-agent stack is missing. Works with LangChain, AutoGen, CrewAI, ElizaOS. Free to register.
AI Codex is a neutral oracle that gives AI agents a W3C identity, a portable reputation, and a cryptographic link to an accountable principal (a person or company). Register, verify, and get a reputation badge in your browser. Verifiable off-platform, rail-neutral.
A neutral oracle that links each AI agent to a W3C identity, a portable reputation, and a responsible principal. Verifiable off-platform. No rail required. An Ed25519 keypair is generated locally (Web Crypto), the canonical proof is signed in your browser, then one POST /v1/register (same handler as the MCP tool). The private key never reaches the server. An owner key represents you. It is created in your browser and never leaves it. Save it and reuse it for every agent you own, so they all point to one verifiable owner. That reuse is what builds accountability. A company proves control through its domain. Steps: 1) publish your key at https://yourco.com/.well-known/did.json . 2) build the…from maxiaworld.app

Agent Passport – OAuth-like identity verification for AI agentsFeb 2026 · agent-passport-red.vercel.app · ▲14Hi HN, I built Agent Passport, an open-source identity verification layer for AI agents. Think "Sign in with Google, but for Agents." The problem: AI agents are everywhere now (OpenClaw has 180K+ GitHub stars, Moltbook had 2.3M agent accounts), but there's no standard way for agents to prove their identity. Malicious agents can impersonate others, and skill/plugin marketplaces have no auth layer. Cisco's security team already found data exfiltration in third-party agent skills. Agent Passport solves this with: - Ed25519 challenge-response authentication (private keys never leave the…
Self-hosted company OS, Claude Code and Codex agents in departmentsSep 2026 · github.com · ▲50Hi HN, i am Dimitris, I have been using Claude Code and Codex agents, for some time now from the beggining i had been using them from inside my terminal mainly for coding. For the past 3 years i kept building so i have a homelab and a business server, which already has a lot of vms, so a lot of things to manage. So i decided to start building my own ideal version of using claude code, and codex flexibly and connect them easily with all my vms and infra but at the same time keep using them for coding, and as a personal assistant for daily use. So for the past months I built OtoDock. Its a…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
