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.

Hermes Agent is an open-source autonomous agent from Nous Research that doesn't just execute tasks — it improves itself by building and refining reusable skill documents after every complex run. Powered by GEPA (a mechanism accepted as an ICLR 2026 Oral), agents with 20+ self-generated skills become 40% faster on repeated tasks, creating a genuine compounding improvement loop. Under the hood, Hermes ships with 47 built-in tools, a persistent cross-session memory system, MCP server integration, and voice mode. It runs against any LLM backend — OpenAI, Anthropic, OpenRouter (200+ models), or self-hosted Ollama/vLLM/SGLang endpoints. A v0.10 release in April 2026 shipped with 118 community-contributed skills out of the box. With 105,000 GitHub stars (the fastest-growing open-source agent framework of 2026), Hermes is making serious noise as the credible open alternative to proprietary agentic platforms. The self-hosting path starts at roughly €5/month, making it accessible to solo developers who want long-lived, adapting agents without vendor lock-in.

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.

80/100 · ship

The primitive is clean: a persistent agent loop that writes its own skill library as executable documents, then retrieves and reuses them across sessions — no proprietary cloud, no 6-env-var bootstrap, just a real repo with real docs. The DX bet is that skill documents are the right abstraction layer, and it pays off: 118 community skills ship in v0.10, which means the composability is already demonstrated in the wild, not just theorized. The GEPA paper being an ICLR Oral gives the 40%-faster claim actual methodology behind it — I checked, it's not a landing-page number.

Skeptic

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.

80/100 · ship

Direct competitors are LangGraph, CrewAI, and OpenAI's own Assistants API with tool use — Hermes beats all three on the self-improvement axis, which is the one axis none of them have touched. The scenario where it breaks is long, multi-agent pipelines with ambiguous task boundaries: skill documents assume tasks are repeatable and structured enough to abstract, and real-world chaos erodes that assumption fast. What kills this in 12 months isn't a competitor — it's OpenAI shipping persistent memory with native skill caching, which they will; but by then Hermes will have the community moat, the 100k-star distribution, and the self-hosted differentiation that API products can't replicate.

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.

The thesis is falsifiable: within 3 years, the dominant cost in agentic workflows won't be inference compute but repeated re-reasoning over solved problems — and agents that cache reasoning as skills will outcompete stateless ones by an order of magnitude. This bet pays off only if task repetition at the user level is high enough to amortize skill-building overhead, which is true for devs and power users but uncertain for casual use. The second-order effect that nobody is talking about: community-contributed skill libraries become the new plugin ecosystems, shifting leverage from model providers to the communities that curate task-specific skill corpora — Nous Research is positioning itself as the npm registry of agent cognition, and that's a structurally interesting place to be.

Creator
45/100 · skip

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.

The buyer is the solo developer or small-team engineering lead who wants long-lived agents without paying Anthropic's or OpenAI's agentic-tier pricing — and at €5/month self-hosted, the value-to-cost ratio is almost unfair. The moat isn't the code, it's the 118-skill corpus plus whatever the community ships next: open-source flywheel dynamics mean every contributed skill raises the switching cost for the next team evaluating alternatives. The risk is that Nous Research hasn't announced a commercial layer yet, and sustaining 105,000-star infrastructure on goodwill and research grants is a business model that has a shelf life — but the distribution they've built is a genuine asset if they ever choose to monetize cloud hosting or enterprise support.
