Goose is an open-source, extensible AI agent originally built by Block (formerly Square) and recently donated to the Agentic AI Foundation (AAIF) under the Linux Foundation. Written in Rust for performance and reliability, it runs locally and automates complex engineering tasks across 15+ LLM providers — including Anthropic, OpenAI, Google, Mistral, and Ollama for fully local operation. It ships with a desktop app (macOS, Linux, Windows), a CLI, and an API. The AAIF donation in early April 2026 put Goose alongside Anthropic's Model Context Protocol (MCP) and OpenAI's AGENTS.md spec as the foundation's inaugural projects — signaling serious intent to create neutral, vendor-independent governance for agentic AI standards. Block's engineering team cited wanting a "neutral home" for the agent as the open-source agent ecosystem matures. For teams that want an AI agent they can actually trust to run on local hardware without phoning home, Goose is the most mature option currently available. Its Rust architecture gives it a reliability and performance edge over Python-based alternatives, and multi-provider support means you're not locked into any one model vendor.

Metrics SQL by Rill
One SQL semantic layer so AI agents stop hallucinating your KPIs

Metrics SQL is a SQL-based semantic layer from Rill Data that solves a specific and painful problem: AI agents that query your data warehouse tend to hallucinate aggregation logic, producing metrics that look plausible but are mathematically wrong. Metrics SQL lets analysts define business metrics once — revenue, MAU, conversion rate, ROAS — in a governed definition layer, and then exposes those definitions as queryable SQL tables. Every dashboard, notebook, and AI agent resolves from the same source. The technical approach is elegant: rather than inventing a new DSL, Metrics SQL extends SQL itself. An agent that knows SQL can query `SELECT * FROM metrics.weekly_revenue` and get correctly computed numbers without needing to know how revenue is defined, which tables it joins, or how edge cases like refunds are handled. The semantic layer intercepts the query, applies the governed definition, and returns correct results. The implications for AI-native data stacks are significant. Currently, one of the biggest failure modes for AI analysts and BI agents is inconsistent metric computation — different agents or dashboards produce different numbers for 'revenue' because they implement aggregation logic differently. Metrics SQL addresses this at the infrastructure level, not by improving agent prompting.
Reviewer scorecard
“Goose in Rust with 15+ provider support is the most serious open-source AI agent for production engineering work. The AAIF donation gives it long-term credibility — this isn't a side project that'll get abandoned when Block's priorities shift. The desktop app is polished and the CLI is fast.”
“We've been burned by data agents that invent their own GROUP BY logic and produce wrong numbers that look right. Metrics SQL solves this at the infrastructure level — define revenue once, have every agent query the same definition. The SQL-native interface means no new tools for agents to learn; they just use the tables.”
“Linux Foundation governance sounds stable until you remember how many projects get donated and then slowly starve of contribution. Block was a real engineering sponsor; AAIF is an unknown quantity. Also, Goose competes with Claude Code and Gemini CLI from companies with massive distribution advantages.”
“The value here is only as good as how well-maintained your metric definitions are — if analysts don't keep them updated, agents query stale or wrong definitions and you've added a layer of false confidence. Adopting a semantic layer also creates vendor dependency; migrating away from Rill's cloud later is a real switching cost. For smaller teams without dedicated data engineering, maintaining a semantic layer is overhead.”
“The AAIF move is politically significant. Neutral governance for MCP, AGENTS.md, and Goose under one foundation could become the equivalent of the Apache Software Foundation for the AI agent era. If that happens, Goose is a very early bet on foundational infrastructure.”
“Data governance and AI agents are on a collision course. As more business decisions are delegated to AI, the correctness of KPI computation becomes load-bearing — a hallucinated revenue figure that influences a product decision is a serious failure mode. Metrics SQL represents a class of infrastructure that will become mandatory as AI takes on more analytical work.”
“The ability to run Goose fully locally with Ollama — no cloud, no data leaving my machine — is the feature that matters for studios handling client IP. Rust performance means it doesn't drag on long creative automation tasks. Solid choice for privacy-sensitive creative workflows.”
“I rely on AI to pull weekly performance data, and the number of times it's given me different 'correct' answers for the same metric is maddening. Having a single governed source that every AI query resolves against means I can trust the numbers I'm making decisions on. That trust is worth a lot.”
