Expand/collapse button in bottom-right corner lets the graph fill the
entire viewport for better exploration. Escape key exits fullscreen.
Category filters overlay in top-left when fullscreen.
Add GET /api/tags endpoint returning distinct tags with counts,
add ?tag= filter to GET /api/memories, and a new Tags tab in the
Neural Archive UI with searchable tag cloud and expandable memory cards.
- Replace $nextTick with setTimeout(100) for D3 render (same fix as dashboard)
- Re-render graph when switching back to tab (not just on first load)
- Fallback width from parent element when container clientWidth is 0
- Use contextvars to resolve user identity from Authorization header
in SSE connections, replacing hardcoded "default" user_id
- memory_recall now includes shared memories (individual + tag-based)
with deduplication and shared_by attribution
- memory_list now includes shared memories with same approach
- All 11 MCP tool functions use _current_user contextvar
- Add "New Memory" button with collapsible form (content, category, tags, importance)
- Add share memory with user typeahead via new GET /api/users endpoint
- Fix dashboard charts not rendering (replace $nextTick with setTimeout for x-if timing)
- Redesign theme: warm walnut/amber palette, Playfair Display + JetBrains Mono fonts
- Update Chart.js and D3 graph colors to match warm theme
Alpine.js + Tailwind CSS (CDN) served by FastAPI StaticFiles — no build step,
zero Docker changes. Features: memory browser with inline edit/delete, full-text
search with debounce, D3.js force-directed graph, Chart.js stats dashboard.
New endpoints: GET /api/stats, GET /api/categories, pagination on GET /api/memories.
- 7 new tools: memory_share, memory_unshare, memory_share_tag,
memory_unshare_tag, memory_update, memory_shared_with_me, memory_my_shares
- Tools only advertised when API key is configured (HTTP_ONLY or HYBRID mode)
- SQLite-only mode stays unchanged — sharing requires the API server
- Tool handlers proxy to REST API endpoints
- New migration 004: memory_shares and tag_shares tables with indexes
- Share individual memories or entire tags with other users (read/write)
- Tag shares are live rules: future memories with shared tags auto-visible
- Recall query merges own + shared memories via UNION, returns shared_by field
- Owner-only delete enforcement (403 for non-owners, even with write access)
- PUT /api/memories/{id} update endpoint with permission checks
- 5 new MCP SSE tools: memory_share, memory_unshare, memory_share_tag,
memory_unshare_tag, memory_update
- Permission helper checks ownership, individual shares, and tag shares
Adds SSE endpoint at /mcp/sse so Claude Code can connect over HTTPS
without needing a local Python bridge script. Benefits:
- No local files or sandbox permission issues
- Works from any machine (OpenClaw, DevVM)
- No startup delay or stderr suppression hack
- Auth via Bearer token in request headers
- Decouple push and pull in _sync_once() so pull always runs even if push fails
- Add startup full resync to catch drift from other agents and schema changes
- Add periodic full resync every ~10 minutes for continuous drift correction
- Add auth failure detection (401/403) with graceful SQLite-only degradation
- Add /api/auth-check endpoint for lightweight key validation
- Add retry cap (5 attempts) on pending ops to prevent infinite queue buildup
- Add orphan reconciliation: push local-only records with content dedup
- Add memory_count MCP tool for sync diagnostics
- Add version-based SQLite schema migration (PRAGMA user_version)
- Fix API key in ~/.claude.json to match server
- Update README with sync resilience docs, test structure, project layout
- Add 30 new tests covering all new behaviors (155 total, all passing)
- Add type annotations to all FastAPI endpoints in api/app.py
- Fix bare list/dict generics in sync.py and app.py
- Fix no-any-return in vault_client.py and sync.py
- Remove mypy || true from GitHub Actions CI — mypy is now clean
- Add type annotations to all _sqlite_* private methods
- Type sqlite_conn as sqlite3.Connection | None with assert narrowing
- Fix _api_request return type (dict[str, Any])
- Add return type to _init_sqlite
- Fix tool_name type in handle_tools_call
- Import sqlite3 at module level
- Blend BM25/ts_rank relevance with importance instead of sorting by one
dimension only. Default mode: 40% relevance + 60% importance. Relevance
mode: 70% relevance + 30% importance.
- Try AND-match first for precise results, fall back to OR-match when too
few results are found. Prevents single-word matches from flooding results.
- Applied to both SQLite (local) and PostgreSQL (API) search paths.
- Add MAX_MEMORY_CHARS=800 Pydantic validation on MemoryStore.content
- Update auto-learn judge prompts: "ONE topic per event", 100-500 chars,
include the WHY not just the WHAT
- Split 9 mega-memories (800-2400ch) into 70 focused memories (100-500ch)
via migration script
Before: median 331ch, 11 memories >800ch, recall wastes 84% of returned tokens
After: median 213ch, 2 memories >800ch (dense single-topic refs), recall returns
only the relevant knowledge
Trade-off research: PostgreSQL ts_rank gives the same score regardless of
document size, so a 2400-char memory with 12 topics gets recalled for any
of its 12 topics but wastes context with the other 11. Focused memories
(100-500ch) give higher signal-to-noise per recall.
Old sync clients without 404 handling get stuck in infinite retry
loops when trying to delete an already-deleted memory. Making the
endpoint idempotent (returning success regardless) fixes this for
all existing clients without requiring client upgrades.
Three fixes for high 4xx alert rate:
1. Catch urllib.error.HTTPError (not just RuntimeError) for 404 on
DELETE in pending_ops — was causing infinite retry loop for
already-deleted memories
2. try_sync_delete: treat 404 as success instead of enqueuing
a retry that will also 404 forever
3. URL-encode the `since` query param to prevent `+` in timezone
offset being decoded to a space (the asyncpg-string-timestamp
pattern applied to the sync client)
The '+' in '+00:00' timezone offsets gets URL-decoded to a space,
causing datetime.fromisoformat() to fail with ValueError. Replace
spaces back to '+' before parsing.
Consolidates plugin components (hooks, commands, skills, MCP config)
into this repo so it can be installed with:
claude plugins install github:ViktorBarzin/claude-memory-mcp
- .claude-plugin/plugin.json: manifest with all hook events
- mcp/memory-mcp.json: MCP server config using existing src/
- hooks/: compaction survival, auto-recall, auto-learn, auto-approve
- commands/: /remember and /recall slash commands
- skills/: memory-management skill
- Bump MCP server to v2.0.0 with metaclaw migration fallback
- Update README with quick install and plugin hooks docs
- Add SyncEngine for background sync between local SQLite cache and
remote API with pending_ops queue for offline resilience
- Refactor MCP server to support three modes: SQLite-only, hybrid
(local cache + sync, new default), and HTTP-only (legacy)
- Add GET /api/memories/sync endpoint for incremental sync
- Change DELETE to soft delete (set deleted_at) for sync support
- Add deleted_at IS NULL filters to all read queries
- Scale API deployment to 2 replicas with pod anti-affinity, PDB,
and startup probe for high availability
- Add migration 003 for deleted_at column and updated_at index
- Add comprehensive tests for sync engine and API sync endpoint
- API recall and list endpoints now return {"memories": [...]} matching
the format expected by the MCP server
- Rewrote README with comprehensive setup instructions for new agents,
accurate API reference, migration docs, and multi-user setup guide
Replace inline migration logic with proper Alembic migrations:
- 001: Initial schema (creates memories table with FTS)
- 002: Add multi-user and secrets columns (user_id, is_sensitive,
vault_path, encrypted_content)
Migrations run automatically on app startup. Existing databases
are handled gracefully with IF NOT EXISTS / column existence checks.
