Best Atomic Notes for Software Engineers

What Atomic Notes actually asks of you

A note holds exactly one idea, written so that someone who never saw it could understand it alone.

Titles are claims, not topics — "Retrieval beats re-reading", not "Learning". If a note needs its neighbors to make sense, it is two notes, not one.

How software engineers put it to work

1. 1

   Decisions at review time, not after

   The architecture decision is captured when the review happens — the alternatives rejected, the constraint that decided it — while the reasoning is still in the room. ADRs written from memory a month later are fiction.

2. 2

   Postmortem seeds during the incident

   Notes start while the incident is live: what was tried, what the dashboards said, what the timeline was. Linked to past incidents, they turn "didn't this happen before?" from folklore into retrieval.

3. 3

   Research trails that survive the tab

   RFC reading and bug hunts leave a linked trail — the Stack Overflow answer, the commit that explained the behavior, the doc that contradicted it. Next time the same error appears, the trail is one search away.

The capture habit, the linking, and the retrieval are the parts tentus automates — atomic notes without the daily upkeep.
