Files Over Prompts

Build HTML Artifacts and LLM Wikis Your Claude Agent Actually Reads

eBook: $9.99 196 pages

Prompts plateaued. Files compound. Build the substrate the smart developers already shipped: a 5-entry LLM wiki by Saturday morning, persistent memory by Saturday night, three throwaway HTML editors by Sunday. No SaaS, no API except Anthropic, every file under your control.

Prompts plateaued. Files compound. The first complete playbook for the era after prompts: a 5-entry LLM wiki by Saturday morning, persistent memory across every Claude session by Saturday night, and three production-grade HTML editors by Sunday. 196 pages, every chapter shipping a working artifact, every file on disk under your control.

What You'll Build

01
The Inversion

Why you're scrolling past Karpathy's wiki wrong, and what changes when the agent reads first.

02
Foundation

Writer-mode vs reader-mode and the 4 rules for organizing data for the reader who isn't you.

03
Build Your First LLM Wiki

The Karpathy skeleton on disk in 90 minutes: 2 folders, a schema file, and 5 entries across PKM, sales, support, code review, and research.

04
Persistent Memory

Three injection mechanisms (file import, Notion + iOS Shortcuts, MCP server) and the Tuesday morning test that proves it works.

05
Retrieval, Linting & Hallucination Compounding

How one wrong summary becomes 16 downstream errors and the weekly lint pass that cuts the tree at level 1.

06
HTML Artifacts, The Pivot

Why you'll stop writing markdown: the 6 reasons, the 6 FAQ counter-objections, and the design-system file every later artifact pulls from.

07
HTML Specs, Plans & Reports

Implementation plan, weekly status report, and research explainer as HTML artifacts your team actually reads.

08
HTML Code Review & Understanding

The PR review HTML you attach to every PR, plus the code-tour HTML for unfamiliar modules.

09
HTML Design Artifacts

Component variants, animation prototypes, SVG flowcharts, and slide decks: the four design-adjacent categories where markdown loses.

10
Custom Editing Interfaces

Three throwaway editors: triage board, feature flag editor, prompt tuner. Each ends with an export, each disposable in the best sense.

11
The Web of HTML Files

Multi-agent, multi-vault, team scale: the verification agent, three-vault topology, and the no-code path for non-developers.

12
When Personal AI OS Is Overkill

The cost ladder, the decision tree, and the maintenance routine that keeps the substrate honest past week four.
