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.

Query Param API Examples

• Search queries
• Sort: client-side, no refiring of model hook
• Sort: server-side, refire model hook
• Pagination + Sorting
• Boolean values. False value removes QP from URL
• Global query params on app route
• Opt-in to full transition via refresh()
• replaceUrl by changing controller QP property

# So, this is pretty horrible. If we just encode using btoa, any UTF-8 chars cause an error.
# If we use either of the workarounds on MDN[1], the £ sign is encoded wrong. I suspect
# Excel totally sucking at encodings is the reason why. So, the workaround is, to use
# the MDN workaround on chars with values > 255, and allow chars 0-255 to be encoded
# as is with btoa. Note that if you use either of the workarounds on MDN, chars
# 128-255 will be encoded as UTF-8, which includeds the £ sign. This will cause excel
# to choke on these chars. Excel will still choke on chars > 255, but at least the £
# sign works now...

NOTE!!!!!!!!! Ended up in trouble going down this path. Followed Rails 3 in Action method instead

generate

rails plugin new importable --dummy-path=spec/dummy --full --mountable && cd importable

in .gitignore change references to test/dummy to spec/dummy (rails bug¿)

spec/dummy/db/*.sqlite3

spec/dummy/log/*.log
