13 Standing context lives in files, one per topic

What people usually ask

Remember that I always want SI units, tables, and no bullet points.

What comes back

“Noted”, and the next session has no record of it.

Ask this instead

Write profile.md for me. It holds my standing rules, one per line, under 50 lines, a title and nothing else above them. Start with these: SI units with the unit after every number; results as a table where there is more than one row; no bullet points in prose; British spelling; when a rule and a task conflict, tell me instead of picking one.
I will attach this file to every chat. Read it as rules to follow, not as an outline to write the answer around.
When I correct the same thing twice in one chat, propose a new line for profile.md and wait for my yes before treating it as a rule.
One file per topic: profile.md for how I want answers, <topic>.md for the standing facts of one job (the rig, the units, the names), under 200 lines each. When a chat touches a topic, I attach that file as well.

Attach: profile.md and the topic file, at the start of every chat.

Why it works: The assistant keeps nothing between chats, so a file attached each time is what carries the rules.
