AgentID is a portable identity layer for AI agents that persists a single name, memory, belief set, and rule system across Claude, ChatGPT, Cursor, GitHub Copilot, Cline, and any MCP-compatible client. Instead of re-prompting each tool independently, you define an agent once and it shows up consistently wherever you work. It includes multi-agent task coordination and real-time status broadcasting for team environments. The system includes automatic system prompt compression that reduces token consumption by up to 65% — a meaningful cost reduction for teams running persistent agents across multiple sessions. Memory entries, beliefs, and rules all synchronize in real-time via a central AgentID hub accessible through a browser interface. The product is positioned at the boundary between AI tooling and human identity, raising interesting questions about agent ownership and portability. The free tier offers one identity with three agents and 50 memory entries — enough for serious individual use.

Block's open-source on-machine AI agent just hit v1.29, introducing Gemini ACP (Agent Client Protocol) support so you can run the full Goose agent stack using your existing Google subscription — no separate API key needed. It also added orchestration for sub-agents, adversarial agent mode to prevent information leaks, delegate sub-agent log display, and macOS sandboxing. With 35k+ GitHub stars and Rust-based architecture, Goose goes far beyond autocomplete: it builds projects, writes and executes code, manages files, and calls external APIs autonomously. The ACP approach means your Goose extensions are passed directly to Gemini, deepening the connection compared to plain CLI usage.
Reviewer scorecard
“The cross-tool identity persistence is genuinely useful for teams using multiple AI coding assistants. The 65% token reduction from prompt compression has real cost implications at scale. The MCP compatibility means it plugs into your existing workflow without rearchitecting anything.”
“This is exactly the architecture I want: a local agent that doesn't lock me into one AI provider's billing. The Gemini ACP integration means my Google One subscription now funds actual dev automation. The adversarial agent mode is also clever — finally an agent that polices itself before it nukes your filesystem.”
“Centralizing agent identity on a third-party service creates a single point of failure for your entire AI workflow. If AgentID goes down or changes pricing, your agents lose their memory and context. The 65% token reduction claim also needs independent verification — prompt compression quality varies enormously.”
“Multi-agent orchestration sounds great until you're debugging a cascade failure at 2am wondering which sub-agent hallucinated first. The 35k stars are real but so is the complexity overhead. Claude Code and Cursor 3 have more polish for day-to-day use — Goose still feels like a power-user project.”
“Portable agent identity is a missing primitive in the current AI tooling stack. Right now, every tool reinvents context management independently — AgentID's model of owning a persistent identity that travels across tools is the right long-term architecture for human-AI collaboration.”
“The ACP subscription model is the thin edge of a wedge that eventually makes AI provider lock-in irrelevant. When agents can switch between Claude, Gemini, and GPT seamlessly based on cost and availability, the moat moves to the orchestration layer. Block is quietly building that layer in the open.”
“For creators managing multi-tool AI workflows across research, writing, and production, having a consistent 'creative assistant' identity that remembers your preferences and style across every tool is genuinely transformative. This reduces the 'cold start' problem on every new session.”
“The MCP Apps and rich UI stuff is interesting for creative workflows, but Goose is fundamentally a developer tool. The learning curve before it does anything useful for non-devs is steep. I'll check back when the Neighborhood Extension for ordering food is the least niche thing it can do.”
