Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.
How agent discovery & health will work →About
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.pyinto 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: conversations ( skipped as too short)

Archive only:
Delete suggested: 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.
