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.

Roo Code is a VS Code extension that embeds a configurable AI development team directly into your editor. Rather than offering a single generic assistant, it ships with specialized work modes — Code Mode for everyday programming, Architect Mode for system planning and migrations, Debug Mode for root cause analysis, and Ask Mode for quick explanations. Teams can also define custom modes for project-specific workflows. The extension integrates with MCP (Model Context Protocol) servers and supports bring-your-own API keys for whatever underlying model you prefer. This keeps the tool model-agnostic, letting teams swap between Anthropic, OpenAI, and open-source models without lock-in. After the original creators pivoted to a commercial product (Roomote), Roo Code transitioned to full community maintenance — but the codebase remains healthy under Apache 2.0. What separates Roo Code from tools like Copilot or Cursor is its multi-mode philosophy: different tasks demand different AI personas. Architect Mode nudges the model toward planning, trade-offs, and long-horizon thinking. Debug Mode roots it in evidence and stack traces. It's a small design choice that meaningfully changes how developers interact with AI across a project lifecycle.

Reviewer scorecard

Builder
80/100 · ship

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.

80/100 · ship

The multi-mode approach is genuinely underrated — switching to Architect Mode feels like talking to a different person and that's a good thing. MCP support and model-agnosticism mean you're not boxed in. Once you add custom modes for your team's workflows this becomes indispensable.

Skeptic
45/100 · skip

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.

45/100 · skip

The original creators left for a commercial product, which is a yellow flag for long-term maintenance. Community-led projects in this space often stagnate within 6 months. Cursor already does 80% of this without any setup friction.

Futurist
80/100 · ship

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.

80/100 · ship

Mode-based AI interaction is an important UX pattern — the idea that your assistant should shift personality and priorities based on the task at hand. Roo Code is proving the concept works before the big IDEs fully implement it.

Creator
80/100 · ship

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.

80/100 · ship

As someone who uses editors for non-code work too, the Ask Mode is surprisingly useful for quick in-editor research and writing. The extensibility means you could build a Markdown editing mode or doc-writing mode without much effort.
