Agent Memory

Persistent state agents keep across sessions — task history, decisions, learned patterns — including offline consolidation mechanisms like dreaming, and its drift and poisoning risks.

Also known as: agentic memory, agent memory, memory, Dreaming, dream mode, memory drift, working memory vs. long-term memory, long-term memory, working memory

DreamingA memory-extension mechanism: the agent reviews past sessions offline to find patterns and self-improve. Operationalizes 'experience' as a post-hoc consolidation step over session logs, distinct from in-context memory or RAG.

Memory driftWhen an agent's accumulated experience (long-term memory writes) silently changes its behavior over time — e.g., generalizing from a few atypical interactions, or leaking data between workflows via shared memory pools.

Working memory vs. long-term memoryWorking memory = low-latency, high-accuracy, session-scoped details needed right now. Long-term memory = knowledge-base-like accumulation across sessions, organized by topic. Author insists they be kept distinct.

memory (multi-timescale)State kept across turns and sessions at multiple timescales: short-term (session history), long-term (CLAUDE.md/MEMORY.md, LangGraph Stores, OpenAI Sessions). Claude Code's three-tier hierarchy (lightweight always-loaded index -> on-demand topic files -> search-only raw transcripts) with the design principle that the agent treats its own memory as a 'hint' and verifies against actual state before acting.

Working memoryWhat the agent is holding right now: the context window plus the goals and scratchpad it tracks. Explicitly 'not built,' only 'managed' — it is not a persistence artifact at all, it is runtime state that vanishes when the session closes.

Tensions

Effort/reasoning: does more thinking make output better, or does more reasoning make it worse (over-engineering / over-editing)?
from: When working with AI coding agents, how should you select the model, its reasoning/effort level, and its context size for a given task?
Assessment: This looks like a head-on collision but is really the corpus resolving a category error, so I keep it as a divergence-under-adjudication rather than a live two-camp fight. The two things bundled into one 'effort' dial are separable: reasoning DEPTH (deliberation and research before acting — what stellaraccident measures as the Read:Edit ratio) versus action SCOPE (how much the model rewrites — what nrehiew measures as over-editing). They are separable but DEFAULT-COUPLED: more reasoning, unconstrained, tends to produce more scope. nrehiew is the empirical bridge — constrained reasoning models are the MOST faithful, proving depth and tight scope combine positively when you address them separately. Fable 5 already acts on this, pairing 'reduce effort' with a distinct anti-over-engineering instruction. The actionable verdict: do NOT cut reasoning depth to fix over-editing (that is stellaraccident's exact grievance and it backfires into shallow, edit-first behavior); keep the depth and add an explicit scope constraint. The failure is treating one knob as if it controls both correctness-depth and edit-scope.
