Prism Coder

What it does

Prism Coder provides AI agents with a "Mind Palace"—a persistent, long-term memory system that survives across sessions. It allows agents to store episodic, semantic, and procedural memories, enabling them to recall decisions, project context, and technical details without re-explaining them in every new conversation.

Tools

• session_load_context: Recovers the state of a prior session on boot.
• session_save_ledger: Appends an immutable log entry of work, decisions, and changes.
• session_save_handoff: Saves the live state for the next session's seamless transition.
• knowledge_search: Performs semantic and keyword search across all stored memories.
• query_memory_natural: Natural-language Q&A over the agent's Mind Palace.
• extract_entities: Automatically pulls people, projects, and decisions from text.
• session_synthesize_edges: Links related memories into a cognitive graph.
