description: Bring the ECHO vault up to the current feature spec (entity index + cross-links)
allowed-tools: Bash(python3 *sweep.py*), Bash(python *sweep.py*), Bash(ls /sessions/*), Bash(dirname *)
---

Use the **echo-memory** skill to bring the vault up to the current spec. Run the sweep **dry-run first**, show the operator the plan, and only `--apply` on their go-ahead:

```bash
SDIR="${CLAUDE_PLUGIN_ROOT}/skills/echo-memory/scripts"
[ -d "$SDIR" ] || SDIR=$(dirname "$(ls /sessions/*/mnt/.remote-plugins/*/skills/echo-memory/scripts/sweep.py 2>/dev/null | head -1)")   # CoWork sandbox fallback
python3 "$SDIR/sweep.py"            # plan (read-only)
python3 "$SDIR/sweep.py" --apply    # write
# Windows: use `python` or `py -3` if `python3` is not on PATH.
```

The sweep (1) creates `_agent/index/`, (2) rebuilds the entity index from existing notes, (3) symmetrizes `## Related` cross-links (adds only the missing reciprocal direction — never invents new links), and (4) stamps the marker `schema_version`. It is idempotent and read-only without `--apply`. If `schema_version` is behind, run `migrate.py` first. After applying, run `/echo-health` to confirm invariants.
