The Art of Simplicity

VS Code's February 2026 (v1.110) release adds manual context compaction via the /compact command to the editor, previously only available in the GitHub Copilot CLI. This lets developers proactively summarize conversation history in agent sessions before the context window fills up, preserving important context while freeing space. Manual compaction works for local, background, and Claude agent sessions, and supports hints about what to keep or discard. The feature is part of a broader effort to make long-running agentic development sessions more reliable and trustworthy for real-world, multi-file tasks.
