backpass is a CLI tool that reads local agent session transcripts from seven harnesses (Claude, Codex, Pi, OpenCode, Grok, Cursor, Hermes) and proposes up to five small edits to AGENTS.md or CLAUDE.md memory files.

Each edit requires verbatim quotes from at least two independent sessions, and writing occurs only via the explicit `backpass apply` command. It requires Node 22.5+ and acpx, uses no API keys, and keeps all transcripts on local disk.
