"description":"Persistent memory via the ECHO Obsidian vault over the Obsidian Local REST API. A cross-platform, connection-pooled Python client: one-call capture/resolve/recall/link over an entity index, hybrid BM25 + graph recall, auto-linking, an offline write-ahead queue, and lock-guarded concurrency. Linter-enforced routing manifest plus /echo-load|save|recall|triage|health|sweep|reflect|doctor commands. Crosslinks notes across Claude and CoWork sessions.",
