### Description (declared)

# AegisDB ↔ Claude Code Memory Integration

Make [AegisDB](https://github.com/d4n-larsson/aegisdb) the **persistent long-term memory** of Claude
Code. The agent gets memory **tools** (save/search/get/update/relate) via an MCP
server, plus automatic **recall** and **capture** via hooks — so knowledge learned
in one session (decisions, conventions, fixes, preferences) is available in later
ones without the user re-explaining it. Each project keeps its own isolated memory.

## How it works

```
Claude Code ──(MCP stdio)──▶ aegis_mcp.server ──┐
Claude Code ──(hooks)──────▶ recall/capture ────┼──▶ AegisDB (NDJSON/TCP)
                             embeddings ─────────┘
```

- **MCP tools** (`mcp__memory__memory_save`, `_search`, `_get`, `_update`, `_relate`) —
  explicit, model-driven memory.
- **`UserPromptSubmit` hook** — automatic recall: injects relevant memories into
  context before each turn, best-effort under a time budget.
- **`SessionEnd` hook** — automatic capture: persists salient session outcomes.
- **Embeddings** — pluggable provider (Voyage / local / none) turns text into
  vectors for semantic recall; the integration never asks the agent for vectors.

All logic lives in dependency-free modules under `aegis_mcp/`; only the MCP server
entry point needs the `mcp` SDK. Memory is always best-effort: if AegisDB is down,
the agent stays fully usable.

## Why it saves tokens

Long context is the real cost driver, and this integration keeps durable
knowledge **out** of the window — feeding back only what's relevant per prompt —
so you spend tokens on the work, not on re-establishing context.

- **Recall instead of re-explaining.** Stack, conventions, decisions, and gotchas
  learned earlier are injected automatically, so you stop re-pasting them every
  session and the model stops re-deriving them.
- **A relevant slice, not a dump.** Recall ranks by similarity × importance ×
  confidence and injects only the top matches — capped by `AEGIS_RECALL_TOP_K`,
  filtered…
