Palace Protocol
What It Does
Defines how agents should interact with MemPalace to maintain data integrity
and get the best results: wake-up sequence, core query-before-assert rules,
memory stack layers, and tool selection guidance for search vs knowledge graph
vs navigation.
When to Use
Load when an agent needs to decide which mempalace tool fits the task, or at
the start of a session that will draw from palace memory. Reference the
"When to Use What" table to pick between search, KG, and navigation tools.
Usage
Wake-Up Sequence
On first interaction with the palace in a session:
- Call
mempalace_status to load palace overview and protocol spec
- Note the wing count, room count, and drawer count
- Use this context to scope subsequent queries
Core Rules
-
Query before asserting: Never state facts about a person, project, or
event without first querying the palace. Use mempalace_search or
mempalace_kg_query to verify.
-
Verify facts: If a memory seems outdated, check the knowledge graph
with as_of date filtering. Facts may have been invalidated.
-
Record learnings: After significant sessions, use mempalace_diary_write
or mempalace_add_drawer to persist new knowledge.
-
Invalidate, don't delete: When facts change, use mempalace_kg_invalidate
to end validity rather than deleting. This preserves the temporal record.
Memory Stack (L0-L3)
| Layer | Content | When Loaded | Token Budget |
|---|
| L0 | Identity context | Always (wake-up) | ~50 tokens |
| L1 | Critical facts | Always (wake-up) | ~120 tokens |
| L2 | Room recall | On-demand (scoped search) | Variable |
| L3 | Deep semantic search | On-demand (cross-palace) | Variable |
- L0+L1 are loaded via
mempalace_status (~170 tokens total)
- L2 is triggered by
mempalace_search with wing/room filters
- L3 is triggered by unfiltered
mempalace_search
When to Use What (Tool Selection)
| Need | Tool | Why |
|---|
| "What do we know about X?" | mempalace_search | Broad semantic search |
| "What's in the auth wing?" | mempalace_search with wing param | Scoped, higher precision |
| "What decisions did we make?" | mempalace_search (filter results client-side by hall type) | No hall filter exists on the tool |
| "Who works on what?" | mempalace_kg_query | Entity relationships |
| "What changed since January?" | mempalace_kg_timeline | Temporal history |
| "How are X and Y connected?" | mempalace_find_tunnels | Cross-wing discovery |
| "Save this decision" | mempalace_add_drawer | Verbatim storage |
| "Update a fact" | mempalace_kg_invalidate + mempalace_kg_add | Temporal fact management |
Content Filing Guidelines
When adding content to the palace:
- Always store verbatim โ never summarize or compress before filing
- Choose the right wing โ match the primary domain (project, person, topic)
- Choose a specific room โ narrow topics get better retrieval
- Check for duplicates โ call
mempalace_check_duplicate before add_drawer
- Include source context โ use the
source_file parameter when available
