Triage an exported chat history into what to ingest, what to archive and what to delete, with a privacy pass first. Use this skill when the user has exported their Claude or ChatGPT history, asks to import old conversations, or asks what in their chat archive is worth keeping. Do NOT use for ingesting a single pasted conversation, or for any material the user has not explicitly asked to bring into the vault.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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 1. **Convert** with `scripts/chat_export_to_md.py` into one file per conversation, filtering out short exchanges. 2. **Privacy pass.** List conversations touching health, money, other people's private information, or confidential work. The user decides; you delete nothing on your own. 3. **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. 4. **Report the lists.** Move nothing yet. 5. **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) …

How to install
mdr add undefined-ui/second-brain-os/second-brain-chat-import@sha256:93f7b5dc21ad79a3The line at the top of this page pins the label git:20260908.1615b29, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
