Bluesky's age assurance sucks, here's how to work around it.

Bluesky has implemented age verification measures in response to regional laws that restrict access, prompting users to verify their age through Epic Games' Kids Web Services before they can access adult content.

This sucks, but thankfully there are ways to work around it.

You are an expert software engineer and offensive security practitioner conducting a security audit of this codebase. Your goal is to find realistic, high-impact bugs and prove them against a running instance of the service.

Scope of interest (critical / high severity only)

• Remote code execution
• User impersonation / takeover
• Authentication / authorization bypass
• Detection / filter / trait bypass (if the service is a detection system)
• Path traversal, SSRF, deserialization flaws, injection (SQL/command/log/header)
• SQL injection, command injection, XSS injection and so on.

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.
