SQLite and memory system patterns specific to the @reactive-agents/memory package. Use when working on the memory layer, database operations, FTS5 search, Zettelkasten, or sqlite-vec KNN.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Memory System Patterns
## Architecture
```
.reactive-agents/memory/{agentId}/
├── memory.db ← Source of truth (bun:sqlite, WAL mode)
└── memory.md ← Human-readable projection (200-line cap, regenerated on flush)
```
SQLite is the source of truth. Markdown files are projections only.
## Four Memory Types
| Type | Storage | Usage |
| ------------ | ------------------------------------- | ------------------------------------------------------- |
| `semantic` | SQLite + memory.md | Long-term knowledge, bootstrapped at session start |
| `episodic` | SQLite | Daily logs + session snapshots |
| `procedural` | SQLite | Learned workflows and patterns |
| `working` | In-process `Ref<WorkingMemoryItem[]>` | Capacity 7, FIFO/LRU/importance eviction, NOT persisted |
## Two Tiers
| Feature | Tier 1 | Tier 2 |
| ------------- | ------------------------ | ------------------------ |

How to install
mdr add tylerjrbuell/reactive-agents-ts/memory-patterns@sha256:c73d2d470692f2c0The line at the top of this page pins the label git:20260315.a07056d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
