Summary

Clean up the false-path code for launched JIT context and memory behavior. This removes the old experimental settings, legacy memory loading/tool surfaces, and docs/tests that described the disabled modes.

Details

  • Make JIT context and the memory context manager the default path.
  • Remove the legacy save_memory tool, /memory add, memory-manager policy, and old server hierarchical memory loader.
  • Update prompts, settings schema, docs, evals, snapshots, and command surfaces to reflect direct markdown memory edits.
  • Keep prompt guidance that explicitly tells models there is no save_memory tool.

Summary of Changes

Hello, 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 streamlines the memory management architecture by removing legacy experimental features, specifically the save_memory tool and the memoryV2 and jitContext settings. By defaulting to direct markdown file editing, the system achieves a more consistent and maintainable approach to persistent context, while also reducing complexity in the CLI and server components.

Highlights

  • Removal of Legacy Memory Tool: The save_memory tool and its associated implementation, policies, and tests have been removed from the codebase.
  • Standardization of Memory Management: The system now defaults to direct markdown file editing for memory persistence, deprecating the need for experimental memoryV2 and jitContext flags.
  • Configuration Cleanup: Removed memoryV2 and jitContext experimental settings from the configuration schema and codebase, simplifying the startup and context management logic.
  • Documentation and Test Updates: Updated all relevant documentation, CLI commands, and test suites to reflect the new memory-first approach and the removal of legacy features.

Code Review

This pull request removes the legacy save_memory tool and the experimental flags experimental.memoryV2 and experimental.jitContext, establishing direct markdown file editing as the primary method for persisting agent memory. The changes involve a comprehensive cleanup of documentation, removal of the /memory add slash command, and deletion of the MemoryTool class and its related logic and tests across the monorepo. I have no feedback to provide.
