Rosetta R3 is out — easier, cheaper, safer, more deterministic.

[omaiesh]

What's new

✋No auto-activation— plain prompts now run the coding agent as-iswith Rosetta guardrails; you opt into the full guided process (discovery, design, review gates) by tagging a workflow.
⚡Cheaper & faster— per-session overhead down to ~3.6K tokens (from ~40K).
🧩Composable— pull in exactly what you need:/hitl(human checkpoint),/tech-specs(spec doc),/reasoning(make it actually think),/orchestration(run a team of subagents). HITL now interviews relentlessly before building.
🛡️Safer by default— a two-tier safety gate blocks catastrophic commands outright and asks before risky ones, with identical safety across Claude Code, Cursor, Copilot, Codex, Windsurf.
⚙️Deterministic— every workflow step runs as a tracked, resumable, auditable plan.
🔧More reliable— fixed server freezes, one config to rule them all, and a single source for every IDE plugin.
✨Does more— new Solr skill suite, full AQA suite, safe legacy-migration mode, post-mortem, requirements reverse-engineering, no-code prompt evals & benchmarking, a plugin generator, plus an official course from the workshops.
🛠️Easier to customize— skills and workflows are just files now (via plugins); write your own with the coding-agents-prompt-authoring flow.
How to use it — you now must tag a workflow to engage Rosetta:

/coding-flow Implement side bar on the home page, ...
/requirements-authoring-flow extract detailed business and technical requirements ... using subagents ...
/ui-aqa-flow Automate the test case for the checkout flow, ...
/api-aqa-flow Implement automation for the API test cases in suite ..., ...
/modernization-flow Perform modernization phase 2 to analyze service module ... Target microservice name is ...Install & migration

🔌Pluginsare now the recommended install path.
📡MCPsteps back to optional, but still supported.
📦R2→ support-only.R1→ fully retired.
💡 Save cost/tokens (optional) — drop this into your workspace AGENTS.md/CLAUDE.md:

MUST ALWAYS think, reason, plan, chat, document in compressed/terse/unicode chars/terms/always/no hieroglyphs; Exclude final artifacts, any tool calls, all code, etc.What's next

🧹 Keep simplifying workflows — fewer steps, less to remember.
💖 Improve developer experience across the board.
This is groundwork, not the finish line — it's what lets us keep simplifying day-to-day use without giving up the guardrails.
