Use when session decisions and pitfalls should survive across days, when multiple agents or dialogs share facts on the same filcompass-drift— Summarize drift signals (green / yellow / red) across recent sessions: distribution, timeline, top yellow signals, and red incident details.compass-recall— Run a one-shot semantic recall against the active project's memory/ entries: top hits with relevance scores, anchor drift annotations, and links.compass-search— Search compass session-summary frontmatter (name, concept, type, drift, body) across all recorded sessions. Returns ranked hits with timestamps and drift glyphs.compass-status— One-shot overview combining Merkle chain integrity, drift trend, BGE daemon liveness, and project memory size. Use this when you want to know "is compass working right now and is the memory I'm about to recall on trustworthy?" without firincompass-verify— Verify the Merkle hash chain over ~/.claude/projects/<project>/memory/ and report any tampered or missing files.
