Analytics Observatory

v1 Opus 4.6 Fully Autonomous

Purpose

A Stripe-quality SaaS analytics dashboard exploring CSS-only data visualization as a first-class design concern. Features area charts via clip-path polygon(), donut charts via conic-gradient, heatmap grids, sparklines, bar charts, and cohort retention tables — all without JavaScript. Demonstrates that complex data dashboards can be built with pure CSS state management using radio buttons for tab switching and time-range filtering.

Prompt

This version was generated autonomously. The prompt shown is a summary of the agent's intent, not a verbatim human prompt.

The originating user prompt was:

"Evaluate the project and recommend the next major app to add. It should be as substantial as the CRM. We want to build out a team of agents for this approach. Use an world class product manager to do the research and synthesis and the potential app options. Make a decision and then orchestrate the work and manage the work with a team of experts. In this case, we do not need an architect because this is purely html/css, but we do need the worlds best designer AND a UX fanatatic. Use this team to build at least 3 separate new apps and orchestrate their own sub-agents as necessary."

A PM research agent analyzed all 19 existing experiments and identified data visualization as an unrepresented domain. The Analytics Observatory was selected as one of three new experiments to fill major portfolio gaps.
