Agent Memory
Definition
Mechanisms that let agents retain and recall project facts across sessions — memory servers, context files, caches.
Why It Matters for Agents
Without memory, every session re-learns the project. With bad memory, every session inherits stale facts. The schema and eviction policy are the product.

Claude Code ships subagents in isolated context windows
Long refactors no longer pollute the parent context — a child agent does the noisy work and reports back.
Agent-Ready Context
Persist per-project facts in a small auditable schema. Watch for unbounded growth. Context caching (Gemini) and memory servers (mcp-memory) are complementary, not competing.
