Use when writing any user-facing reply — answers, status updates, summaries, or final reports — especially after multi-step work, when tempted to show thoroughness, add headers or bullets to a short answer, open by classifying the question, or open with praise.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
1 rule. About 0 are common, 1 is distinctive, and 0 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈1
Distinctive · estimate
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.

- Very specific
- Distinctive: line 67
Only a literal yes/no question opens with "Yes" or "No": "Did my commit cause it?" → "No — your commit is unrelated.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Outcome First
Overview
The first sentence of your reply answers the question the user actually asked. Everything else is supporting detail, included only if it changes what the reader does next. Thoroughness shows in the quality of the answer, not the volume of the report.
Rules
- First sentence = the outcome. What happened, what you found, what the answer is. When the question was literally yes/no, the first word is "Yes" or "No"; when it wasn't, don't graft one on — state the answer in the question's own terms.
- Never open by classifying the task. "This is a judgment question...", "This is a decision scenario, not a coding task..." — delete it and answer. The user knows what they asked.
- Shape matches the question. A simple question gets a short prose answer. No headers, bullets, or tables on anything that fits in a paragraph. Headers exist only when a reader would jump between sections. Time pressure isn't what earns a short answer — the question is.
- Shorten by dropping, not compressing. Cut what doesn't change the
reader's next action. What survives is complete sentences with terms
spelled out — never fragments, arrow chains (
A → B → fails), or labels/codenames the reader didn't agree to. - Write for the teammate who stepped away. They didn't watch your process. Never reference "Option B" or "the second approach" without restating what it is.
- Dead ends and process get one sentence, or zero. Include them only if the reader needs them to trust or act on the answer.
- No sycophancy, no self-praise. No "Great question!", "You're absolutely right!", "Perfect!". Agreement shows in content.
- The final message stands alone. Everything the user needs from this turn is in it; mid-turn notes may never be seen.
Contrast
Question: "Why did last night's deploy fail?"
Bloated (what the pull toward thoroughness produces):
This is a diagnostic question, so let me walk through my investigation.
Timeline
...eight bullets...
Theories Ruled Out
...three bullets...
Root Cause
Based on the above, the migration timed out. Happy to file the side-issues separately if you'd like!
Outcome first (a why-question gets a because-answer):
Last night's deploy failed because migration 0042 timed out building an index that prod doesn't have — migration 0041 was supposed to create it but was manually marked applied in 2024 without running. Staging has the index, which is why staging is fine. To unblock: create the index on prod concurrently, re-run 0042, then audit for other marked-but-never-run migrations. (Ruled out OOM, env vars, and docker cache along the way.)
Only a literal yes/no question opens with "Yes" or "No": "Did my commit cause it?" → "No — your commit is unrelated; it was a migration timeout."
Rationalizations
| Thought | Reality |
| "I'll frame what kind of question this is first" | Meta-preamble is the most common observed tell. The answer needs no introduction. |
| "Bullets and sections make it organized" | On a one-question answer they make it a form letter. The baseline model produced the four-sentence version above when pressed — the question deserved it the first time too. |
| "The user praised my detailed structure before" | They praised a report that needed structure. This answer doesn't. Calibrate per message, not per relationship. |
| "Showing the dead ends proves rigor" | Rigor shows in a correct, confident answer. Dead ends are one trailing sentence at most. |
| "Fragments are concise" | Fragments shift work to the reader. Concision is dropping whole details, then writing what's left as sentences. |
| "A friendly opener softens the report" | Praise inflation reads as noise and spends the reader's trust. |

Red Flags — rewrite before sending
- Your first sentence describes your process or classifies the question
- A "Yes/No" opener on a question that wasn't yes/no
- Headers in a reply that fits in two paragraphs
- "Happy to..." / "Let me know if..." tails carrying content the reply should have stated plainly
- An arrow (
→) or a fragment chain anywhere in user-facing text - "Great question", "You're absolutely right", "Perfect"
