# The 30-second cache rule

Cross-AI portability is the structural moat OpenAI and Anthropic can't build for themselves. The user's context, exported as a public URL, becomes infrastructure that survives any single vendor's pivot. That's why the right primitive isn't an API key — it's a permalink.

The hardest part of a 1-person startup isn't the work — it's the lack of a forcing function. Without a meeting on Tuesday, nothing has to ship on Monday. The schedule has to come from somewhere, and "because I said so" isn't enough.

Markdown won because it was always good enough. Not the best at any one thing — never the fastest editor, never the prettiest output, never the most semantically rich. But always close enough that the switching cost killed every alternative.

```swift
// SwiftUI: keep all five tab views mounted across tab switches so
// each view's @StateObject model persists.
ZStack {
    ForEach(AppTab.allCases, id: \.self) { tab in
        view(for: tab)
            .opacity(router.selectedTab == tab ? 1 : 0)
            .allowsHitTesting(router.selectedTab == tab)
    }
}
```

| Provider | Strength | Weakness |
|---|---|---|
| Claude | Long context, instruction following | Slow for tiny prompts |
| GPT-4o | Multimodal, fast | Drifts on long sessions |
| Cursor | Code-aware ranking | Locked to editor |

The thesis here[^1] is that delivery model matters more than retrieval quality.

## Recap

The hardest part of a 1-person startup isn't the work — it's the lack of a forcing function. Without a meeting on Tuesday, nothing has to ship on Monday. The schedule has to come from somewhere, and "because I said so" isn't enough.

## Concepts in this document
- **Output-Heavy Systems** _(concept)_
  Knowledge tools that prioritize surfacing information over capturing it.
- **Linear** _(entity)_
  Design philosophy benchmark for default-easy, hard-possible workflows.
- **Long-Context UX** _(concept)_
  The shift from retrieval-based systems to presentation-based systems.
- **Permalink Infrastructure** _(concept)_
  Using public URLs as a vendor-agnostic portability layer.
- **Forcing Functions** _(concept)_
  External constraints required to maintain productivity in solo ventures.

## Concept relations (within this doc's concepts)
