Filesystem-backed StorageBackend for Node — content-addressed and CAS-safe; the CLI's default store.

SQLite storage backend (WAL mode) providing persistent Stores and file storage for all runtime state.

Google Drive storage backend: document stores and file blobs persisted to a folder in the user's Google Drive, authenticated in-browser via Google Identity Services.

Profile-aware StorageBackend for Node — partitions selected namespaces (sessions by default) per web principal over the filesystem layout, with a `profile` CRUD tool. Default principal keeps the existing base layout.

matbot core runtime: agentic loop, hook dispatch, plugin loader, config, security, and knowledge. Exposes ./providers-base and ./storage-base for plugin authors.

matbot plugin API: the singleton contract every matbot plugin builds against — MatbotPlugin, the service registry, hooks, principal carrier, and shared types.

matbot CLI: interactive REPL and single-turn runner for the matbot AI harness, with hot-loadable plugins.

Anthropic Messages API provider adapter with streaming, tool use, and extended thinking; also handles DeepSeek's Anthropic-compatible API.

Built-in `plugin` and `provider` tools for managing plugins and LLM providers at runtime — install, remove, reload, and discover.

Session-management tools: list, get, rename, and hide conversation sessions.

OpenAI-compatible chat completions provider adapter (OpenAI and any compatible endpoint) with streaming and tool calls.

Make HTTP requests (method, headers, body) to web APIs and remote resources; requires the network capability.

Override the web frontend's request principal with the host OS user ($USER).

Node skills plugin: embeds @matatbread/matbot-skills CRUD and adds a local filesystem (.md) import + watch.

Web UI with session management. Node entry serves it over HTTP+SSE; browser entry mounts the same UI in-process. Both share index.html + app.js.

Node filesystem-backed FileStore for MIME-typed blobs, served by the frontend.

Data-driven hooks: stored conditions that, when an LLM classifier judges them matched, invoke a tool. Cross-runtime (node + browser).

Browser-native backends for the web frontend: an IndexedDB Store, an OPFS file store, and a WebCrypto-backed vault.

Replaces the bash tool with a persistent Docker container (exec-based). Project root is read-only at /app; .data is read-write.

Contextual knowledge fault handler — looks up the knowledge index when the model encounters an unknown term.
