Three-Tier Agent Memory

Memory that survives restarts without filling the context window, in plain files any agent can read.

Three-Tier Agent Memory product illustration

The three tiers

  • Working: memory/NOW.md, current goal, next step, blockers (loaded every session, max 40 lines)
  • Episodic: memory/log/YYYY-MM-DD.md, one dated line per event (searched, never loaded whole)
  • Long-term: memory/MEMORY.md, durable facts with date and source (loaded every session, max 150 lines)

The script

memory.py does init, log, promote (dedupes, refuses secrets), recall (ranked keyword search across all three tiers), lint, forget and archive. 19 tests; Python 3.9+, standard library only.

Honest limit

Recall is keyword search, not embeddings: write facts in the words you will search for.
