v0.15.3

v0.15.3 — Agent Behavior Management & Context Improvements

Release Date: May 19, 2026

🎉 New Features

• clean_behavior Command — Agents can now clean their own learned adaptive behaviors, giving them the ability to self-reset behavioral patterns when needed.
• Debug System Prompt Command — Added a new debug command to view the current agent's system prompt, making it easier to inspect and debug prompt configurations.
• Context Awareness System Prompt — Agents now receive a context-awareness system prompt that helps them understand and respect token limits during conversations.
• MCP Server Full Support — The Agent Communication Protocol (ACP) now fully supports MCP servers, enabling richer tool integrations through the ACP interface.
• Job Memory Persistence — Jobs can now store memories when an explicit memory_path is passed, allowing long-running job executions to persist and recall information.

🐛 Bug Fixes

• Context Transfer Fix — Tool-shrinked messages are no longer included in transfer context, preventing bloated context when transferring between agents.

🔧 Improvements & Chores

• Reworded Context Flow — Improved messaging for better context flow during agent interactions.
• Default Model Updates — Replaced some default models with more up-to-date alternatives.
• Delegate Tool Scoping — The delegate tool is now only available when 2 or more agents are configured, reducing unnecessary tool clutter for single-agent setups.
