CLN Connections
You already have a system. CLN is not a competing framework — it is the notation
layer that turns "notes" into "structured data" that both humans and AI can
parse instantly.
01/Zettelkasten Integration
ATOMICITY
+ 1 CLN Block = 1 Atomic
Idea.
+ Operators define the idea "type"
(def, risk, action) at a glance.
+ Links become explicit: use
= [Link] for semantic
connection.
02/Second Brain / PARA
STRUCTURE
. Project notes: use
. for next actions and
! for blockers.. Area notes: use
= for guiding principles.
. Resource notes: use
= for definitions and
* for key takeaways.
03/First Principles Thinking
= CLN
forces decomposition: you cannot write a block without
defining the core.
= Indentation provides a visual map of the
logic's breakdown.
04/Extended Mind
* Unstructured thought → Externalized
structure.
* Environment holds the logic; the brain holds
only the intent.

is the file format for your second brain.
