When a user installs mem0-plugin, mem0 starts empty even though Claude
Code has been quietly accumulating their CLAUDE.md instructions,
auto-memory, and subagent learnings on disk for months. The existing
hooks capture live state going forward but cannot backfill what already
exists.
This commit adds a one-shot importer that walks every Claude state
surface and backfills it into mem0:
- `mem0-plugin/scripts/import_claude_state.py` (new, ~575 lines):
discovers CLAUDE.md hierarchy (+ @imports), .claude/rules,
~/.claude/projects/*/memory, and ~/.claude/agent-memory; chunks each
file at markdown headings (H2 default, H3 for oversize sections,
small-sibling merge, code-fence safe); tags chunks with metadata
matching the existing mem0-mcp skill vocabulary (convention /
user_preference / task_learning / anti_pattern / decision); POSTs
sequentially to /v1/memories/ with infer=True (server-side dedup).
Marker file at ~/.mem0/imports/claude-state.json tracks content-hash
per chunk for idempotent re-runs and crash-resume safety.
Flags: --dry-run, --reset, --no-infer, --source <type>.
- `mem0-plugin/scripts/on_session_start.sh`: adds a one-time nudge
block after the existing bootstrap output. Emits the holistic-import
prompt only when ~/.mem0/imports/claude-state.json doesn't exist
and the SOURCE isn't "compact". Propagates to Cursor and Codex for
free (shared bash entry point).
- README, CHANGELOG, plugin.json bumped to 0.2.0.
Patterned exactly on the existing on_pre_compact.py: stdlib only
(urllib, hashlib, pathlib, argparse), reuses _identity.resolve_user_id,
same logging setup, same ~/.mem0/ storage convention. Zero new packages,
zero new deps.
Smoke-tested locally: --help renders, missing MEM0_API_KEY exits 1
with helpful message, hook emits nudge when marker absent and stays
silent when marker present.
