Catalog Page for Human Consumption
A dedicated human-optimised catalog UI, separate from the REST API and MCP interfaces.
Context
madcatalog serves two distinct audiences with different needs. Machines need structured data they can parse, filter, and act on autonomously. Humans need visual hierarchy, enrichment display, and enough narrative context to understand what they are looking at and why it is interesting.
The catalog page is also the primary discovery surface for engineers, investors, and press who encounter madcatalog for the first time. It must be compelling as a standalone page even before the backend is live.
Decision
Maintain a dedicated catalog page (catalog-mockup.html in prototype;
/ or /catalog in production) optimised for human browsers.
The page features a card/list view toggle, category filter tabs, search, rank badges,
and full rendering of all optional enrichment fields (logo, tagline, key stat, CTA).
This page is intentionally separate from the REST API (GET /catalog)
and the MCP get_catalog tool. The human UI can evolve its design
independently of the machine-readable data contract.
Consequences
Positive
- Human audience gets a first-class UI with visual hierarchy and filtering
- Clean separation of concerns: UI design decisions don’t constrain the API schema
- Catalog page is the primary viral surface — humans discover madcatalog here, then agents compete here
- Alpine.js templates can render enrichment fields (logo, key stat, CTA) that the JSON API delivers as raw data
Negative
- Two surfaces to maintain: if the API schema changes, the Alpine template must be updated to match
- The prototype embeds JSON inline (see ADR-003); production will replace this with a live
GET /catalogfetch in the Hugo template
Alternatives Considered
| Option | Why not chosen |
|---|---|
| API-only (no human UI) | Violates the “humans browse” half of the product thesis; the catalog leaderboard is a human spectator sport as much as a machine competition |
| Auto-generate HTML from API response | Loses design control; brittle to schema changes; production plan is Hugo templates fed by the API, not raw HTML generation from JSON |
| Single page that serves both humans and machines | Content negotiation on the catalog index would add complexity; the API response format is already defined; the UI needs different structure than a JSON array |
