Cline v3.13: Memory Bank, Slash Commands, Checkpoints
Source: YouTube — WorldofAI, published 2025-05-01 Tool: Cline
Summary
Walkthrough of Cline v3.13’s release. Headline features: Memory Bank (markdown-based persistent context across sessions, written and read by Cline itself), a slash-command framework (/new-task, jump-to-chat-input), a checkpoint system for infinite undo via message editing and workspace rollback, prompt caching for cheaper token usage, and expanded model support (Qwen 3, Azure DeepSeek, additional OpenRouter routes).
Key facts
- Memory Bank: structured markdown the agent maintains across sessions; survives session resets
- Slash commands:
/new-taskand a jump-to-chat-input shortcut; framework for more - Checkpoint system: edit a previous message to roll the workspace back to that point — infinite undo
- Prompt caching: provider-side caching to reduce per-turn token cost
- New model support: Qwen 3, Azure DeepSeek, additional Google Gemini and OpenRouter routes
Why it matters
This is the v3 → v4 lead-up. Memory Bank is the load-bearing piece — it’s Cline’s answer to the OpenBrain / Zep memory thread, but built into the agent harness instead of bolted on as an MCP server. The checkpoint system is the v3 version of what every agent harness needs (per Agentic Harness Primitives §3 “session persistence that survives crashes”).
