The collaboration layer for AI engineering teams
Edit, version, diff and roll back prompts from a visual dashboard with no coding, so product, marketing and content teams can iterate on prompts while engineers keep control of the deploy.
Run dataset-backed tests with human and AI graders, trigger regression evals whenever a prompt changes, backtest new versions against historical data and compare prompts across models.
Connect production traces to the exact prompt version that produced them and inspect failures, cost, latency and token usage by feature, model or user.
Build, trace and improve agent workflows with prompts, tool calls, evaluations and logs in one place, so multi-step runs can be tested before they ship.

Agent Skills that give your coding agent real design taste
Every Skill is designed, written and tested by the Skillry team, with templates and scripts built from a finished piece of work.
Skills cover web pages, slide decks, images, video and reports, so your agent can produce a range of assets.
Install and run Skills inside Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI and more.
Each Skill page shows a real result it generated, so you can judge the visual style before adding it.

SpecialistInstalls directly as a design skill pack to enforce UI rules, whereas Skillry acts as a broader discovery library.
