Tip:
LLMs are very good at following conventions (this is actually what is happening when it writes code).
If you create a .md file with a list of entries of the following structure:
#
#
...
where an is a stable and concise sequence of tokens that identifies some "thing" and seed it with 5 entries describing abstract stuff, the LLM will latch on and reference this. I call this a PCL (Project Concept List). I just tell it:
> consume tmp/pcl-init.md pcl.md
The pcl-init.md describes what PCL is and pcl.md is the actual list.
I have pcl.md file for each independent component in the code (logging, http, auth, etc).
This works very very well.
The LLM seems to "know" what you're talking about.
You can ask questions and give instructions like "add a PCL entry about this".
It will ask if should add a PCL entry about xyz.
If the description block tends to be high information-to-token ratio, it will follow that convention (which is a very good convention BTW).
However, there is a caveat. LLMs resist ambiguity about authority. So the "PCL" or whatever you want to call it, needs to be the ONE authoritative place for everything. If you have the same stuff in 3 different files, it won't work nearly as well.
Bonus Tip:
I find long prompt input with example code fragments and thoughtful descriptions work best at getting an LLM to produce good output. But there will always be holes (resource leaks, vulnerabilities, concurrency flaws, etc). So then I update my original prompt input (keep it in a separate file PROMPT.txt as a scratch pad) to add context about those things maybe asking questions along the way to figure out how to fix the holes. Then I /rewind back to the prompt and re-enter the updated prompt. This feedback loop advances the conversation without expending tokens.
