Mnemos — Task-Scoped Memory Lifecycle

What It Does

Mnemos prevents lossy context compaction from destroying the structured knowledge you need most. It treats your working memory as a typed graph (MnemoGraph) where different types of knowledge have different eviction policies:

  • GoalNodes and ConstraintNodes are NEVER evicted — they survive all compaction
  • ResultNodes are compressed (summary kept) before eviction
  • ContextNodes are evictable when their activation weight drops
  • CheckpointNodes persist to disk for session resume

Fatigue Model

Mnemos monitors 4 dimensions of "agent fatigue" — all passively observed from hook data, no manual input needed:

Dimension Weight Signal Source What It Measures
Token utilization 0.40 Statusline JSON How full the context window is
Scope scatter 0.25 PreToolUse file paths How many directories the agent is bouncing between
