Summary of Changes

Hello @kwaa, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refactors the server by introducing a new API for retrieving recent episodic memories. It provides two endpoints: one for raw JSON data and another for markdown-formatted summaries suitable for LLM consumption. This enhancement allows for more flexible and human-readable access to conversational memory, improving the system's ability to recall and present past interactions.

Highlights

• New Recent Memory API: Introduced /api/v0/recent_memory and /api/v0/recent_memory/raw endpoints to retrieve episodic memories, supporting filtering by conversation ID and time limits.
• Dependency Updates: Added chrono-humanize for human-readable time formatting and plastmem_entities for database entity definitions.
• TypeScript SDK Integration: Updated the TypeScript SDK to include new types and client functions for the recentMemory and recentMemoryRaw API endpoints.

Changelog

Code Review

This pull request introduces a new API for retrieving recent episodic memories, providing both raw JSON and formatted Markdown outputs. The implementation is solid and integrates well with the existing architecture. I have identified a few areas for improvement, primarily concerning input validation for the limit parameter and potential issues with u64 to i64 casting and deprecated chrono::Duration::days usage for the days_limit parameter. Addressing these will enhance the robustness and safety of the API.
