AgentDB v0.4.0

AgentDB is now the complete embedded database for AI agents.

One file. Eight layers. Zero servers. Nine language SDKs.

New Features

AI-Native Layers

  • Conversation threading — _adb_conversations + _adb_messages tables with full CRUD API (db.conversations())
  • Workflow persistence — _adb_workflows + _adb_workflow_steps for durable multi-step agent tasks (db.workflows())
  • Reasoning traces — _adb_traces with tree-structured chain-of-thought and recursive CTE traversal (db.traces())

Developer Experience

  • Transaction API — db.transaction(|tx| { ... }) for ACID closures + db.execute_batch() for atomic multi-statement execution
  • Interactive CLI shell — agentdb shell <path> or agentdb -i <path> — readline-style REPL with multi-line SQL, dot-commands (.stats, .collections, .inspect, .help, .quit)

Multi-Language SDKs

  • Go (go/) — cgo wrapper, full FFI surface coverage
  • Java (java/) — JNI wrapper with Maven POM, try-with-resources
  • C# / .NET (dotnet/) — P/Invoke wrapper with NuGet project, IDisposable

Infrastructure

  • Dockerfile — multi-stage build (rust:1.75 builder + debian:bookworm-slim runtime), OCI labels, VOLUME /data, <30MB final image
  • Schema v2 — 7 new tables + 5 indexes (additive, backward-compatible)
