    "headline": "One of the most agent-native open-source agents on the market — Rust-built, MCP-deep, provider-agnostic, and now vendor-neutral under the Linux Foundation.",
    "body": "goose (originally from Block, donated to the Linux Foundation's Agentic AI Foundation in 2026) is the rare local agent that reads as infrastructure rather than a product wrapper. It ships three surfaces — a native desktop app, a full CLI, and an API — built in Rust for portability, and it treats the Model Context Protocol as a first-class integration layer rather than a bolt-on, with 70+ documented extensions. For an agentic ecosystem picking durable components, three things stand out: it is genuinely provider-agnostic (15+ LLM providers, and it can ride your existing Claude/ChatGPT/Gemini subscription via ACP), it is Apache-2.0 open source with no pricing lock-in, and its governance now sits with a vendor-neutral foundation instead of a single company's roadmap. The security posture it advertises — prompt-injection detection, tool-permission controls, sandbox mode, an adversary reviewer — is more than most agents bother to name, though we assessed it from the public surface only and did not exercise those controls hands-on. That is the honest boundary on this review: the maturity signals (45k+ stars, 500+ contributors, an active extension ecosystem) are strong and externally corroborated, but Hlido reviewed the public surface, not a full hands-on run, so execution-grit and day-to-day reliability are inferred from the ecosystem rather than measured here. On what is visible, goose is a serious, well-architected, agent-first tool.",

  "tier_rationale": "STEADY (84) because the public surface shows an unusually agent-native architecture (CLI + API + deep MCP + ACP), transparent open-source access (Apache-2.0, no pricing lock-in), a named security model, and strong third-party maturity signals (45k+ stars, 500+ contributors, Linux Foundation governance). Held below VITAL because this is a public-surface Tier-1 review — Hlido did not run goose hands-on, so its execution reliability, the effectiveness of its advertised security controls, and real-world task success are inferred from ecosystem signals rather than independently measured.",
