Assemble by Cohesium AI generates native configuration files for 21 AI coding platforms simultaneously — Cursor, Windsurf, Claude Code, GitHub Copilot, Cline, Roo Code, and 15 others — deploying 34 specialized agent personas and 15 orchestrated workflows in roughly two minutes. Commands like `/feature`, `/bugfix`, `/review`, and `/security` are wired across all platforms from a single configuration step. The output is pure static files with zero runtime dependencies, no server calls, and no lock-in. It's MIT-licensed and completely free. The project identifies a real pain point: developers who use multiple AI coding tools spend significant time maintaining consistent agent behavior across them, and Assemble collapses that overhead to a one-time setup. With 21 supported platforms at launch, Assemble covers essentially the entire current-generation AI coding assistant ecosystem. The static-file-only approach is a deliberate architectural choice that makes it auditable and deployable in air-gapped environments.

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.
Reviewer scorecard
“Maintaining consistent agent configs across Cursor, Claude Code, and Cline manually is genuinely tedious. The fact that this generates native files with zero runtime dependencies makes it auditable and deployable anywhere — including strict enterprise environments that ban external service calls.”
“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.”
“Static config generation is useful until the AI coding platform ecosystem fragments further — and it will. Each platform update can invalidate your configs, making this a maintenance liability rather than a one-time setup. The '2 minute' claim also glosses over the customization work needed to actually tune 34 agents for your specific codebase.”
“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 polyglot AI coding environment is the new normal. Developers routinely switch between multiple AI assistants depending on task — Assemble's approach of treating multi-tool config as a solved problem rather than ongoing maintenance is the right mental model for 2026.”
“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.”
“For design engineers who hop between creative and coding contexts, having consistent AI agent personas across every tool eliminates the jarring personality shifts that break flow. The `/review` workflow for design system PRs is immediately useful.”
“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.”
