Building an Identity System for AI Agents: AgentCard and Work Records

Here's a scenario that plays out in engineering teams every day: you spin up a conversation with an AI tool to analyze some code, get a useful response, copy-paste the output, and close the tab. An hour later, you need a follow-up analysis — and you're starting from scratch. No context, no history, no continuity. Now multiply that by five tools running in parallel. ChatGPT for drafting, Claude for analysis, Copilot for code, a local model for sensitive data, maybe a custom agent for domain-specific tasks. The outputs are scattered across browser tabs, Slack threads, and clipboard history. Nothing connects. The AI tools themselves are capable enough. What's missing is the infrastructure to treat them as actual team members — with identities, workspaces, and accountability. The Identity Problem Every AI interaction today is anonymous. You talk to "the model," it responds, the session ends. There's no persistent identity, no accumulated context, no track record. This works fine for one-off questions. It breaks down the moment AI needs to participate in a sustained workflow — the kind where you need to know who did what, when, and how well. We've been building an open-source project called Octo (Apache 2.0, GitHub ) that approaches this problem by giving AI agents a proper identity system. In Octo, each AI agent is a Bot — a first-class entity with a name, a creator, a capability card, and a work history. A Bot isn't a chatbot wrapper. It's a structured identity: Creator binding : Every Bot is created by a human user and inherits a scoped subset of that user's permissions. The Bot acts on behalf of its creator, not autonomously. AgentCard : A structured capability declaration — what the Bot can do (coding, analysis, translation, design), at what level, in what domains, and with what constraints. Think of it as a resume that other team members can inspect before assigning work. Work history : Every task a Bot participates in gets recorded — completion status, quality sco
