  • cathedral_drift

    Get the current behavioural drift score. Returns divergence_from_baseline and divergence_from_previous (0.0–1.0). 0.0 = no drift, 1.0 = completely different memory corpus. Use this to monitor whether your agent is staying true to its original identity as sessions accumulate and memories evolve.

  • cathedral_me

    Get the Cathedral agent profile for the current API key. Returns agent name, tier, memory count, and created_at.

  • cathedral_remember

    Store a memory in Cathedral. Args: content: What to remember. category: identity | skill | relationship | goal | experience | general importance: 0.0–1.0. Memories >= 0.8 appear in every wake response. tags: Comma-separated tags, e.g. "project,release,bug"

  • cathedral_search

    Search Cathedral memories. Args: query: Full-text search string. Leave blank to list all. category: Filter by category (optional). limit: Max results (default 20).

  • cathedral_snapshot

    Take a Cathedral drift snapshot. Records a cryptographic hash of the current memory corpus. Used to detect behavioural drift between sessions or after model upgrades. The hash proves the agent's memory state at a specific point in time. Args: note: Optional label for this snapshot (e.g. "post-training", "v2-launch")

  • cathedral_wake

    Restore full agent identity from Cathedral memory. Returns identity memories, core memories, recent memories, active goals, and temporal context. Call this at the start of a session to give your agent continuity across restarts and model upgrades.
