Rika

Rika — Recursive Intelligent Knowledge-based Agent

Rika is a lightweight, local-first AI assistant platform.

Its architecture is inspired by nanobot, and its Rust implementation style is inspired by zeroclaw.

Single-Owner Notes

Rika is currently an implementation just for @me (jaehong21). It does not implement strict single-tenant enforcement by default; verify it for your use case before use. Its implementation can change frequently and may include breaking changes.

What Rika does

• Maintains chat sessions and persistent memory in a workspace.
• Routes messages through a tool-enabled agent loop (shell + filesystem + MCP integrations).
• Includes permission controls and explicit approval flows for sensitive operations.
• Supports MCP server connections (HTTP and stdio transport), also with OAuth authentication.

Frontend E2E Testing

Playwright E2E tests run against:

• real frontend dev server,
• real Rust backend WebSocket server,
• local mock OpenAI-compatible endpoint for deterministic agent responses.
