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.

Mo
GitHub bot that flags PRs conflicting with decisions made in Slack

Mo is a GitHub PR governance bot with a genuinely narrow and original focus: it enforces team decisions made in Slack, not code quality. The workflow is simple — tag @mo in any Slack thread to approve a decision, and Mo stores it. When a PR opens, Mo diffs the changes against every stored team decision and flags conflicts directly in the PR review. It ignores style, linting, security, and complexity — just alignment with what the team actually agreed to build. The problem it solves is real and under-addressed: engineering teams make architectural and product decisions in Slack threads that evaporate from institutional memory within days. Six months later, a new engineer ships something that contradicts a decision nobody remembers. Mo creates a lightweight, searchable decision audit trail and connects it to the code review gate where it can actually matter. Built by Oscar Caldera (ex-agency founder, Motionode), Mo topped Product Hunt's developer tools chart on April 8 with 85 upvotes. It occupies a genuinely different niche from GitHub Copilot, Reviewpad, and other review automation tools — none of which track team decisions as a first-class concept.
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.”
“The scope is exactly right: one job, done well. Architectural drift from forgotten Slack decisions is a real and expensive problem. A bot that sits in the merge gate and catches those conflicts before they ship is worth setting up in any team above five engineers.”
“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.”
“Decision quality is only as good as the decisions teams choose to log. In practice, tagging @mo for every meaningful decision requires behavior change that most teams won't sustain. And diff-based conflict detection on natural language decisions is prone to false positives that create noise and get ignored.”
“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.”
“Team memory as a first-class software engineering concept is underbuilt. Most of our tooling is around code review, not decision review. Mo is an early prototype of what 'organizational memory infrastructure' looks like when it's native to the workflow rather than a wiki nobody reads.”
“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.”
“For design-engineering teams, this solves a constant pain point: design decisions made in Figma comments or Slack that get overridden in implementation. If Mo can log those decisions and catch conflicts at PR time, it's worth integrating.”
