    Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.
    Fix: Protect agent memory and state from modification by untrusted content. Use read-only memory for critical instructions and validate all state changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mempalace scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

MemPalace — AI Memory System

Persistent, structured, local-only memory across sessions. 19 MCP tools. Source: https://github.com/milla-jovovich/mempalace

Relationship to OpenClaw's built-in memory: OpenClaw writes raw daily logs to memory/YYYY-MM-DD.md. MemPalace adds a structured, searchable layer on top — semantic search across all sessions, a temporal knowledge graph for network facts, and per-agent diaries. Use daily logs for "what happened today" and MemPalace for "what did we decide and why."

How to Call the Tools

All tools use mcp-call with the mempalace MCP server:

python3 $MCP_CALL "python3 -u $MEMPALACE_MCP_SCRIPT" <tool-name> '<arguments-json>'

Palace Read Tools (7)

mempalace_status — Palace Overview

python3 $MCP_CALL "python3 -u $MEMPALACE_MCP_SCRIPT" mempalace_status '{}'

Returns total drawers, wing/room counts, palace path, memory protocol instructions, and AAAK dialect spec. Call this at session start to load palace context.

mempalace_get_aaak_spec — AAAK Dialect Spec

python3 $MCP_CALL "python3 -u $MEMPALACE_MCP_SCRIPT" mempalace_get_aaak_spec '{}'

Get the AAAK dialect specification — the compressed memory format MemPalace uses. Call this if you need to read or write AAAK-compressed memories.

mempalace_search — Semantic Search

python3 $MCP_CALL "python3 -u $MEMPALACE_MCP_SCRIPT" mempalace_search '{"query":"why did we configure OSPF area 10 as stub","limit":5}'

Parameters:

  • query (required): Natural language search
  • limit (optional, default 5): Max results
  • wing (optional): Restrict to wing
  • room (optional): Restrict to room

Semantic search. Returns verbatim drawer content with similarity scores.

mempalace_list_wings — List All Wings

python3 $MCP_CALL "python3 -u $MEMPALACE_MCP_SCRIPT" mempalace_list_wings '{}'

List all wings with drawer counts.### mempalace_list_rooms — List Rooms

python3 $MCP_CALL "python3 -u $MEMPALACE_MCP_SCRIPT" mempalace_list_rooms '{"wing":"wing_netclaw"}'

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
