SmartAssist Rust Implementation - Full Parity Specification

Overview

This specification defines the complete implementation requirements for achieving 100% feature parity between the Rust and Node.js implementations of SmartAssist.

Implementation Status

All 4 phases are complete. The implementation exceeds the original specification:

Implementation Priority

Phase 1: Core Infrastructure (Weeks 1-4) ✓

1. Model providers (Anthropic, OpenAI)
2. Gateway RPC methods (chat., agent.)
3. Core tools (bash, read, write, edit, glob, grep)

Phase 2: Channels (Weeks 5-10) ✓

1. Telegram (full implementation)
2. Discord (full implementation)
3. Slack (full implementation)
4. Signal, WhatsApp, iMessage, Line, Web

Phase 3: Advanced Features (Weeks 11-16) ✓

1. Plugin SDK
2. Browser automation tools
3. Memory/vector search
4. All remaining tools

Phase 4: Platform & Polish (Weeks 17-20) ✓

1. CLI completeness
2. Configuration validation
3. Comprehensive testing
4. Documentation

Type Conventions

All specifications use these Rust type conventions:

• String for owned strings
• &str for borrowed strings
• Option<T> for optional fields
• Vec<T> for arrays
• HashMap<K, V> for objects/maps
• serde_json::Value for dynamic JSON
• chrono::DateTime<Utc> for timestamps
• uuid::Uuid for unique identifiers

Error Handling

All operations return Result<T, Error> where appropriate. Errors should:

• Be typed using thiserror
• Include context for debugging
• Be serializable for RPC responses
• Support retry logic where applicable

Async Runtime

All async code uses tokio runtime with:

• async-trait for async traits
• futures for stream utilities
• tokio-stream for async iterators
