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.

Nous Research open-sourced Hermes Agent in late February 2026, and it has since hit 65,000+ GitHub stars — making it the fastest-growing open-source agent framework of the year. The core innovation is a persistent skill system: Hermes doesn't just remember facts, it creates, refines, and deletes its own procedures over time, genuinely improving from each interaction rather than starting fresh. The agent ships with 47 built-in tools, a pluggable memory backend (ChromaDB, Weaviate, or Postgres), MCP server integration, and a cross-platform architecture covering Telegram, Discord, Slack, WhatsApp, Signal, Email, and CLI. Voice mode works across all platforms. Hermes supports OpenAI, Anthropic, Gemini, and local Ollama models — the self-improvement loop runs regardless of which provider you're using. What separates Hermes from agentic frameworks like LangGraph or AutoGen is the explicit focus on genuine skill accumulation rather than just memory retrieval. If Hermes solves a complex coding problem in a novel way, it writes that solution approach as a reusable skill. Next time a similar problem appears, it pulls the skill rather than re-solving from scratch. Community benchmarks show 3x faster task completion on repeated problem types after two weeks of use.
Reviewer scorecard
“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.”
“The skill system is the real differentiator — after two weeks running Hermes on my dev workflows, it handles PR review, dependency updates, and test generation faster than when I started because it learned my patterns. MCP integration means any tool I already use can be wired in. MIT license is the final reason to ship it now.”
“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.”
“Self-modifying agents that write their own procedures introduce unpredictable failure modes. I've seen Hermes create a 'skill' that worked great in one context and caused subtle bugs in another — and the agent kept using it because it remembered success. The debugging story for when it goes wrong is not mature enough for production use yet.”
“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.”
“Hermes Agent represents the first credible open-source implementation of the learning-by-doing paradigm. Every other agent framework treats capabilities as static — you configure tools at startup. Hermes treats capabilities as emergent. That architectural shift is as important as the jump from rule-based to neural systems was a decade ago.”
“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.”
“I set up Hermes to manage my content calendar, source inspiration, and draft social media from a weekly creative brief. By week three it had a skill for my exact brand voice and preferred emoji density. My 'configure it once and forget it' dream finally came true — it actually learns instead of needing constant re-prompting.”
