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.

Gemini CLI is Google's open-source terminal AI agent that brings Gemini 2.5 Pro directly into your development workflow — for free with a personal Google account. Announced April 8, 2026, it's Google's direct answer to Claude Code and OpenAI Codex, shipping under the Apache 2.0 license and installable in seconds via npm. The agent uses a ReAct (Reason and Act) loop with built-in tools plus support for local and remote MCP servers, giving it access to your file system, shell, and any MCP-compatible service. With a 1 million token context window, it can reason across entire codebases, generate features, fix bugs, and improve test coverage without losing track of what it's doing. Developers can customize behavior through GEMINI.md system prompt files — the same pattern Claude Code popularized with CLAUDE.md. The free tier — powered by a personal Google account — is a significant move. Most comparable agents require paid subscriptions or API budgets. Google is betting that putting a frontier model in every developer's terminal for free will accelerate adoption faster than any pricing strategy could. For developers who want open-source, inspectable, extensible terminal AI without a credit card, Gemini CLI is the most compelling option released this year.
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.”
“Free Gemini 2.5 Pro with 1M context in my terminal, Apache 2.0 licensed, with MCP support? This should have been a paid product and Google is giving it away. For hobby projects and open-source work, this is an instant install.”
“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.”
“The 'free with a Google account' framing means you're paying with your data and usage patterns. Rate limits on the free tier will bite you during any serious project, and Google's history with developer tools (see: every API they've deprecated) makes betting on this for production work risky.”
“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.”
“Google open-sourcing a frontier model terminal agent under Apache 2.0 is a land-grab for the AI-native developer ecosystem. GEMINI.md files, MCP integration, and a 1M context window set a new baseline for what 'free developer tooling' means in 2026.”
“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.”
“As someone who does both code and content work, having a terminal agent that can reason about a million tokens of context — scripts, assets, docs all at once — changes how I think about scoping creative-technical projects. The price of zero removes every reason not to try it.”
