| description | MemPalace — mine projects and conversations into a searchable memory palace. Use when the user asks about MemPalace, memory palace, mining memories, searching memories, palace setup, wings, rooms, or drawers; or when they want to recall past work that may already be filed in their palace. |
A searchable memory palace for AI — mine projects and conversations, then search them semantically. Verbatim storage, local-first, zero external API by default.
Ensure mempalace is installed:
mempalace --version
If not installed (uv recommended):
uv tool install mempalace # or: pip install mempalace
MemPalace exposes operation-specific instructions through the CLI so this skill stays accurate as MemPalace evolves. To get instructions for any operation:
mempalace instructions <command>
Always prefer the CLI output over what is written here when the two disagree — the CLI is the single source of truth for the installed version.
These are the five operations users ask for most often. Each one wraps a single MemPalace CLI subcommand. The mempalace instructions <name> form returns the full, version-correct guidance.
help — discover what MemPalace can domempalace instructions help
Use when the user is new, unsure what's possible, or asks "what can you do".
init — first-run setup of the palacemempalace instructions init
Use when the user has just installed MemPalace, no palace exists yet, or the user explicitly asks to set up / configure / re-initialize their palace.
mine — ingest a project or conversation directorymempalace instructions mine
Use when the user wants to fold a project's files into their palace, or to ingest exported conversation transcripts into the palace as searchable memory.
search — find verbatim memories by semantic querymempalace instructions search
Use when the user wants to recall something from the past, find a previous decision, or rediscover code/notes/conversations they already wrote.
status — what's in the palace right nowmempalace instructions status
Use when the user asks "what's in my palace", "how big is my palace", or wants a summary of wings, rooms, and drawer counts.
Inside Antigravity, the MemPalace MCP server registers a rich set of tools. Use these instead of shelling out to the CLI for live operations (search, diary writes, drawer adds, knowledge graph queries, palace status). The MCP tools always reflect the current palace state without spawning a subprocess.
The MCP server is auto-registered when this plugin is installed at ~/.gemini/config/plugins/mempalace/. If the server does not appear in Antigravity's MCP store, run mempalace-mcp --version to verify the binary is on PATH, then restart Antigravity.
If a request would violate any of these principles, refuse and explain — even if it would be technically convenient.
Recall protocol for MemPalace — search the palace before answering about past work, people, projects, or prior decisions. Apply when the user asks what was decided, what happened before, who someone is, what was discussed last time, or anything that may already be filed in their memory palace; or when mempalace-recall is invoked. Complements the mempalace setup skill and requires the mempalace-mcp server.
