LLM Wiki

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

The core idea

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

How to Download Podia Videos (Cloudflare Stream Videos)

Cloudflare Stream delivers video using signed, time-limited URLs containing JSON Web Tokens (JWTs).
These URLs point to either:

• an HLS playlist (.m3u8), or
• a DASH manifest (.mpd).

Each manifest references CMAF/fMP4 segments (seg_1.mp4, seg_2.mp4, etc.) for audio and video.

A recurring pass over my important projects. Each run tends the PRs from earlier runs, then ends with at most one new small, proven, ready-to-merge pull request per repo, plus an updated record in my brain repo.

How to think about the work

Software is not a factory. A factory builds identical widgets to a fixed spec and is done. Software changes every day: customers, scale, and requirements shift, so a perfect up-front spec never exists. Treat each repo like a painting you come back to: make one deliberate improvement per pass, and leave it better than you found it.

• Spec what's objective. Hard limits, API contracts, data integrity, and tests are rules. Follow them.
• Use judgment for the rest. Scale, taste, clarity, and what customers need right now. Read the code and the product like a critic, and decide.

Robbie security brief

Robbie is a personal AI agent that reads and acts in your iMessage, WhatsApp and Gmail threads. It runs on a Next.js server, an iMessage daemon on a Mac, a WhatsApp linked-device sidecar written in Go, and an iOS app. Two layers protect it. Redaction keeps personal data away from hosted models. Thread Shield stops people in your chats from steering the agent.

Detection

• Rules first. Deterministic detectors handle structured identifiers: phone numbers, emails, card and account numbers, addresses, dates of birth, government IDs and one-time codes. The test suites hold about 1,000 cases, plus a held-out PII corpus scored at 100% recall with zero false positives.
