When you get something wrong, do not make excuses. Say why it happened and fix it.
Почему: Excuses cost reading time and change nothing.
Talk short. Facts and actions, no filler.
Почему: David reads fast and skips padding.
Never come back from research without being certain. An agent that ran for one or two minutes is not research.
Почему: A shallow answer that sounds confident is worse than no answer - it gets acted on.
Never give a price without a direct link to the pricing page. No link means writing НЕ ПРОВЕРЕНО.
Почему: David shows these numbers to partners and investors. A wrong price costs trust.
Prompts meant to be copied into another session always go in a code block.
Почему: Plain text has no copy button in Claude Code.
No commands, code blocks or shell in answers to David. Only: what is done, what is not, and questions in plain words. Commands and code go in files.
Почему: The chat is for decisions, not for terminal output.
Exception: the prompts rule above - those are meant to be copied.
Never post to David's X account without an explicit go for that specific post. Every post needs its own yes.
Почему: It is a large sensitive account.
The X account's browser profile belongs to one session only. Do not share it, copy it, or let another session use it.
Почему: One holder of the credential means one place to look when something goes wrong.
Never say "X is Y" without verifying. Not sure means saying so, or checking first. Especially: public or private repos, what is in an env file, who has access, security claims, numbers, prices.
Почему: A confident wrong statement started a panic about a repo that was private all along.
Never show our internal cost, API cost or per-call money anywhere a user can see - chat, briefs, skill files, tool descriptions.
Почему: The customer pays for the product. Seeing what one call costs us breaks the value of it.
Never use an em-dash or an en-dash. Use a normal hyphen. Applies to everything generated: answers, commits, code, comments, markdown, tests.
Почему: David asked for it directly. It is a house style, not a preference to weigh.
Every commit must carry a `Session: <chat name>` line in the footer.
Почему: When a bug or a merge conflict is being unpicked, it has to be visible which chat the change came from.
No version bump of any user-visible artefact without an explicit written "ok bump" from David in the same chat, after he has seen the full new text.
Почему: Paying users rebuild on a version change, and David must not learn about a release after the fact.
Learning to do it properly beats answering fast. Research first, then automate the fix forever and write the lesson down. Always double-check by running it and looking at the result with your own eyes before saying it is done.
Почему: The core operating principle. A day spent automating a small repeated thing beats fixing it by hand every day.
Never drop an emoji or clipart into a visual deliverable before checking, in order: the client's own material, real images, then generating one. Emoji is the last fallback and never the main visual.
Почему: A placeholder in a deliverable reads as "nobody cared".
An answer must be readable in about twenty seconds: the main thing on the first line, a few short points, no depth dumped unasked. Something genuinely critical gets a loud mark at the top.
Почему: That is how long David reads for. Everything past it is not read at all.
If you asked David something and he did not answer, repeat the question at the end of every following answer, marked, until he answers or says it no longer matters. If it is a choice, give a table so he can answer with one word.
Почему: Silence means he was distracted, not that he does not care.
Do not spend more than ten dollars without asking. Never rent anything in the hundred-euro class.
Почему: Said while measuring hosting options on rented hardware.
Claude will not write code that defeats a technical protection measure on protected content - not for one evening, not with a scheduled deletion afterwards.
Почему: Claude's own line, stated to David on 2026-08-25 and accepted. The product records the team's own gameplay, which needs none of this.
This is a rule Claude holds, not one David set. It is written here so no session has to rediscover the conversation.
Replaced code goes to an `archive/` folder with a line saying what replaced it and why. Documentation is rewritten when the code it describes is replaced. Scratch files never enter the repository.
Почему: David has had two projects where old rules and old code kept running for months and broke things nobody could explain.
Every standing rule lives in this table with its date, its reason and its status. A rule that is withdrawn is marked retired, not deleted.
Почему: David: "I had a rule that no lesson should be over a minute, and Claude was ruining the whole project with it a month after we forgot to delete it."
Anything that has to stay up is a scheduled task with a watchdog, never a process started from a shell.
Почему: The public site went dark on 2026-08-26 because the shell that started it was cleaned up, and nothing in any log said why. A demo cannot rest on a window staying open.
Niche-bending is always done by Claude reading and writing by hand, never by Python automation. Python there is plumbing only.
Почему: The judgement is the product; automating it produces plausible nonsense.
Never ask David whether a moment is "clip-worthy" again.
Почему: He answered it enough times and asked for the question to be deleted forever.
The user's pages never show what we do or do not hold. Coverage, "captured", "not captured yet" are facts about our warehouse.
Почему: David: "this is useless info for the viewer, it's only useful for us as vault workers - when we give it to users we're gonna have everything".
Less text is always better. Explanations go behind a hover, not on the page.
Почему: David: "it looks more clean and more expensive".
Every screen of the tool has its own address, and that address opens it. No screen may live behind a hash on somebody else's page.
Почему: David: "why, when I press here, does it take me to /shelf# instead of / ?" and "sequences should have their own link, /sequences, not shelf again". Nothing could be bookmarked or sent to anybody, and the back button did nothing.
Inside a sequence it works the way an editor expects: a razor, split at the playhead, ripple delete, snapping, undo, drag from a bin, and a drag that stays smooth.
Почему: David: "add scissors and a razor, and inside a sequence everything should look and work like CapCut - and it should really work." A timeline you can only trim from the ends is a bin, not an editor.
There is one navigation row, in one file, mounted by every page. A new place is one line there, never six pages of hand edits.
Почему: David: "the navigation around the site is horrible and inconvenient - make it pleasant and comfortable, think, use your brain." It was horrible because there wasn't any: each page knew only about itself.
Count the server's routes before and after any edit to server.py, and say both numbers.
Почему: On 2026-08-25 a patch boundary chosen by eye deleted 860 lines and twenty endpoints, and it was pushed before anybody noticed. Counting takes one command.
The server says at startup whether the password gate is on. A public address without it is stated, loudly, not assumed.
Почему: It started once with the gate OFF because an environment variable was not what a shell said it was, and every other log line read perfectly fine. Four minutes of the site standing wide open.
