AgentDB Query

Query and manage AgentDB through the controller bridge. AgentDB exposes 15 agentdb_* MCP tools; this skill enumerates the standard usage path.

When to use

When you need to store, retrieve, or search knowledge across agent sessions. AgentDB provides hierarchical storage, causal knowledge graphs, semantic routing, and context synthesis.

Steps

1. Check health — mcp__plugin_ruflo-core_ruflo__agentdb_health. Sanity-check available: true.
2. Start session — mcp__plugin_ruflo-core_ruflo__agentdb_session-start if not already active.
3. Store knowledge — mcp__plugin_ruflo-core_ruflo__agentdb_hierarchical-store for structured tier-keyed data (tiers: working|episodic|semantic).
4. Recall knowledge — mcp__plugin_ruflo-core_ruflo__agentdb_hierarchical-recall with a query.
5. Search patterns — mcp__plugin_ruflo-core_ruflo__agentdb_pattern-search for learned patterns (ReasoningBank-routed).
6. Synthesize context — mcp__plugin_ruflo-core_ruflo__agentdb_context-synthesize to combine multiple memories.
7. Build causal graph — mcp__plugin_ruflo-core_ruflo__agentdb_causal-edge to link related knowledge.

Available controller groups

Call mcp__plugin_ruflo-core_ruflo__agentdb_controllers to list the runtime registry. Functional categories surfaced via the 15 MCP tools:

• Hierarchical — agentdb_hierarchical-store, _recall (tier-routed)
• Pattern — agentdb_pattern-store, _search (ReasoningBank-routed)
• Semantic — agentdb_semantic-route, _context-synthesize
• Causal — agentdb_causal-edge (graph-node backend with bridge fallback)
• Lifecycle — agentdb_health, _controllers, _session-start, _session-end
• Bulk — agentdb_batch (≤500 entries), _consolidate
• Quality — agentdb_feedback

Important: namespace handling

Namespace strings apply to memory_* and embeddings_search only. The agentdb_hierarchical-*, agentdb_pattern-*, and agentdb_causal-edge tools route by tier or controller, not namespace. Don't pass namespace: 'foo' to those tools — it will be silently ignored. See plugin README "Namespace convention".

Operational fallbacks (branch on these)

• controller: 'memory-store-fallback' — pattern persisted via memory_store --namespace pattern. NOT a failure.
• _graphNodeBackend: true — causal-edge handled by @ruvector/graph-node.
• success: false, error: '...Use memory_store/memory_search instead.' — bridge unavailable; switch to memory_* tools per the README replacement table.
