Built-in tools for @theokit/sdk agents — file system, git, subprocess, search-text, vitest runner.

Local interactive-shell backend for @theokit/sdk — a node-pty implementation of InteractiveBackend. Opt-in, terminal-surface only; node-pty is optional so install never fails on a native build.

Inter-agent dispatch for @theokit/sdk — typed Handoff descriptors, loop protection, plugin-based wiring.

Memory subsystem for @theokit/sdk — MemoryProvider impls (markdown file store today; LanceDB + embeddings + circuit breaker next iters). Consumes the kernel-facing port from sdk-core.

Semantic LLM response cache for @theokit/sdk — vector + FTS hybrid lookup, in-memory + JSON file stores, plugin integration.

AI agents as first-class citizens of the TheoKit pipeline. The AgentBuilder.create() authoring chain compiles to the @theokit/sdk runtime.

TypeScript SDK for the Theo agent harness — same surface, local or cloud.

USD-cost-aware BudgetTracker impls for @theokit/sdk — extends the counter-based reference with per-model pricing. Consumes the kernel-facing BudgetTracker port from sdk-core.

GitHub OAuth 2.0 provider for @theokit/sdk/server/auth. Plugs into defineAuth({ providers: [github({...})] }).

Developer CLI for @theokit/sdk — init, dev, inspect, eval. Adoption Roadmap #1.

TheoKit's presentation layer — the canonical AgentOutputEvent + Presenter Strategy that turns @theokit/sdk agent output into any surface (web UIMessageStream, terminal ANSI, JSON API) from ONE normalized event.

Google OAuth (OIDC) provider for @theokit/sdk/server/auth. Plugs into defineAuth({ providers: [google({...})] }).

Email magic-link provider for @theokit/sdk/server/auth. Pluggable MagicLinkStore + email-callback for any transport (Resend/SendGrid/SMTP).

Supermemory memory adapter for @theokit/sdk — wraps supermemory@^4 with the MemoryAdapter contract (ADR D141).

Mem0 cloud memory adapter for @theokit/sdk — wraps mem0ai MemoryClient with the MemoryAdapter contract (ADR D141).

Multi-platform messaging gateway core for @theokit/sdk — transport-agnostic primitives (BasePlatformAdapter, MessageEvent, SessionRouter, DeliveryRouter, GatewayRunner, hooks). Inspired by hermes-agent/gateway. ADRs D170-D181.

Honcho memory adapter for @theokit/sdk — wraps @honcho-ai/sdk with the MemoryAdapter contract (ADR D141).

Agent Client Protocol (ACP) server adapter for @theokit/sdk. Exposes an SDKAgent over stdio JSON-RPC so any ACP-compatible host can drive it. ADRs D349-D360.

Agent-first DI integration for @theokit/di. Ships @InjectAgent() decorator + createAgentProvider() helper that produces a REQUEST-scoped Agent factory — so every HTTP request gets an isolated @theokit/sdk Agent automatically.

Multiplayer realtime plugin for TheoKit — presence + room + broadcast + Yjs CRDT (opt-in). Form 4 Hybrid: RealtimeProvider interface + MemoryRealtimeProvider default + YjsRealtimeProvider + defineRealtimeProvider extension. Consumes @theokit/sdk@>=1.7.0 s
