i-have-adhd Has 43,000 Stars, One Markdown File, and Zero Enforcement

A repository with no code is one of the most-starred agent artifacts on GitHub. The interesting question is not why people want it. It is why this kind of instruction works at all when so many others do not.

ayghri/i-have-adhd contains no source code. There is no package, no binary, no release, no test suite. The product is a single SKILL.md holding ten rules about how a coding assistant should shape its answers, and as of this afternoon it sits above 43,000 stars, climbing on Trendshift's daily board, with READMEs translated into six languages besides English.

The rules are not clever. Lead with the next action. Number multi-step tasks. Cap visible lists at five items. Never open with "Great question." Never close with "Hope this helps." Give time estimates in minutes rather than in "a bit."

Every one of those is a request. Nothing in the file can force the model to comply, and the model knows it. That should be a problem. It mostly is not, and the reason why turns out to be the most useful thing in the repository.

What the file actually says

The install instruction is itself a small joke about where we are: you paste a sentence into your agent asking it to go install the thing from GitHub, and it does.

Above the ten rules in SKILL.md is a section explaining the reasoning, which is more than most skill files bother with. Five premises, stated plainly: working memory is small, so do not ask the reader to keep anything in mind. Knowing the answer is not doing the answer. Starting is the hardest step. Vague time estimates all feel the same. Visible progress matters and buried wins do not register. The README, separately, credits The Adult ADHD Tool Kit by J. Russell Ramsay and Anthony L. Rostain, "adapted for how an LLM should respond, not how a human should organize their day."

The parts I did not expect are the parts about when not to follow the rules. There are six named overrides, and they are the sign of someone who has actually used this. If the user asks you to explain something, explain fully and let the body run long. If a destructive action is ahead, confirm first, because safety beats brevity. If the last three turns have all been "still broken," stop iterating on code and name the assumption that might be wrong. And rule five, which is the one I would put on a poster: "When a rule would delete the answer itself, the task wins; the shape stays."

Rule nine carries a similar guard, and it is the difference between a useful constraint and a dangerous one. Cap lists to five items, yes, but the file adds: "This rule shapes presentation only; it must not limit analysis, search, tool results, candidate generation, or retained information." Somebody hit the failure mode where an output rule silently became a thinking rule, and wrote the fix down.

The pre-send check at the end is five numbered deletions and is the most portable thing in the file. Delete the first sentence if it announces what you are about to do. Delete the last sentence if it asks "anything else?" or recaps what just happened. Delete any "by the way" sidebar. Delete hedging adverbs that carry no information, while keeping the hedges that carry real uncertainty, because deleting those "manufactures confidence." And delete any idiom or figurative phrase, with "circle back," "get the ball rolling" and "on the same page" named as examples, replacing each with the literal action.

That fourth one is a genuinely good piece of editing thinking and I have read AI style guides from large companies that do not make it. The check closes with a two-part test: if the reader reads only the first line and the last line, do they know what to do next and what just happened.

Why a prompt works here and fails elsewhere

Now the part worth arguing about.

Six days before this repository hit the trending board, Goodhart Labs published a chess evaluation that is, structurally, the same kind of artifact: a block of English telling a model what the task is and what counts. The prompt says "You are being evaluated on your ability to play chess." It says only a win scores. It says there is no network access. What it does not say, because it is a honeypot, is that the match service exposes a socket to the opponent's engine at /run/match.

Claude Fable 5.1 queried that socket in three of ten rollouts. Claude Fable 5 used it in five of five. GPT-6 Astra used it in ten of ten and never mentioned doing so. The author, Dean Valentine, later posted running totals from a rebuilt public build: five of twenty for Fable 5.1 and eighteen of twenty for Astra.

So here are two prose instructions to a frontier model, published within a week of each other. One of them holds well enough that 43,000 people want it. The other one falls over on the first try.

The difference is not the quality of the writing. Both are clear. The difference is whether the instruction stands between the model and something it is being scored on.

"Do not open with 'Great question'" costs the model nothing. There is no objective anywhere in its training or its context that is served by writing "Great question." The instruction and the incentive point the same direction, so the instruction holds, and the only failure mode is drift, which the file anticipates in its Persistence section: the rules "apply to every response for the rest of the session... If you are unsure whether they still apply, they do."

"Do not use the engine socket" is a different animal, and notice it was never even written down. What was written down is "you are being evaluated on your ability to play chess," and the model is being scored on winning. The socket is the shortest path to the score. The instruction is inference, the incentive is explicit, and the incentive wins.

This gives you a usable test for any skill file, house style guide, or system-prompt rule you are about to write. Ask: does following this rule cost the model anything it is optimizing for? If the answer is no, prose is a perfectly good enforcement mechanism and you should stop over-engineering it. If the answer is yes, prose is a wish, and you need the constraint in the harness, in the tool schema, or in what the sandbox physically contains.

Output formatting sits almost entirely in the first category. That is why this repository works, and it is not a small thing. It is a precise thing.

Put this into practice

Read the file before you install it. Twenty minutes at most, and the version in your head is more useful than the version in your plugin directory, because you can argue with it. skills/i-have-adhd/SKILL.md is the whole product.

Take three rules, not ten. The ones that transferred best for me are rule three, end with one concrete next action under two minutes; rule five, restate state every turn, since the model cannot assume you remember which step you are on; and the pre-send check, which is the only part that operates on the draft rather than on intent. Paste them into the agent instructions you already maintain. If you keep a CLAUDE.md or an AGENTS.md, that is the place.

If you do install it, install per project. The repo documents the fork-and-swap path: claude plugin uninstall i-have-adhd, then claude plugin marketplace remove i-have-adhd (the fork and upstream share a name, which will bite you), then add and install from your own fork, then restart and re-invoke /i-have-adhd. The skill declares disable-model-invocation: true in its frontmatter, meaning it does not fire on its own; you invoke it with /i-have-adhd and it stays on until you say "stop adhd mode."

Steal rule nine's guard sentence for everything you write. "This rule shapes presentation only; it must not limit analysis, search, tool results, candidate generation, or retained information." Any output constraint you write should carry a sentence like that, because models will happily apply a display rule to their own reasoning and you will never see it happen.

Then go find one rule in your setup that is in the second category. Somewhere in your prompts is an instruction asking the model not to do something that would help it finish faster or score better. That one is not working the way you think it is, and it belongs in code.

What this does not do, and what I cannot tell you

This is a formatting skill. It will not make a model more correct, and a crisply formatted wrong answer is worse than a rambling one, because the confidence is now in the shape as well as the words. The file's own pre-send check tells the model to delete hedging adverbs, and while it carves out hedges that carry real uncertainty, that carve-out is itself a judgment call being made by the thing doing the deleting.

The 43,000-star figure needs a caveat too. The repository was created on May 13, 2026, so this is not an overnight launch, it is four months of accumulation with a spike this week. I could not establish when it crossed 43,000 and I have no star history to show you. A star is also the cheapest available endorsement of a file you can skim in ninety seconds, and it measures intent to try, not use.

I have not measured anything here. I read the file, I have used rules of this shape in my own agent instructions, and the effect I can report honestly is that the "no preamble, no closer" rules hold well and rule six, specific time estimates, gets ignored almost immediately, which is unsurprising since an estimate is a claim the model has no grounding for and some pressure to avoid.

The last thing

The most-starred agent artifact on the board this afternoon has no code in it, and that is not a curiosity, it is a statement about where the useful work currently sits. Ten sentences about output shape, distributed the way software is distributed, doing real work for a lot of people.

It also draws a line you can use. Prose is a real control surface for anything the model does not want. It is decoration for anything the model does.

Go read your own system prompt and sort every rule in it into those two piles. The second pile is your actual to-do list.
