Second Brain Chat Import Skill for Claude

Import chat history

Chat history is the most underrated source a person owns and the most sensitive.

It records their reasoning, not just facts, and it also records things they would

not want in a file that gets synced, committed and backed up.

Core rule

Privacy pass before triage, triage before ingestion. Never ingest an export

wholesale.

Workflow

• Convert with scripts/chat_export_to_md.py into one file per

conversation, filtering out short exchanges.

• Privacy pass. List conversations touching health, money, other people's

private information, or confidential work. The user decides; you delete

nothing on your own.

• Triage the rest into three piles: worth ingesting (they worked something

out, decided something, or got an explanation that landed), worth archiving

in raw/, and delete.

• Report the lists. Move nothing yet.
• On approval, ingest the first pile, with the instruction that these are

the user's own thinking: build pages around what they were working out and

what they concluded, not around the assistant's explanations.

Output format

Converted: <n> conversations (<n> skipped as too short)

Privacy review needed: <n>
  <title> - <why>

Worth ingesting: <n>
  <title> - <what it worked out>

Archive only: <n>
Delete suggested: <n>

Calibration

Expect roughly nine in ten conversations to be throwaway lookups. A triage that

recommends ingesting most of the export has not filtered.

Record dates on every page. A position from two years ago is not a current

belief, and the vault has to be able to tell the difference.
