## Highlights
- **Context Management:** Introduced a Context Compression Service to optimize
context window usage and landed a background memory service for skill
extraction.
- **Enhanced Security:** Implemented context-aware persistent policy approvals
for smarter tool permissions and enabled `web_fetch` in plan mode with user
confirmation.
- **Workflow Monitoring:** Added background process monitoring and inspection
tools for better visibility into long-running tasks.
- **UI/UX Refinements:** Enhanced the tool confirmation UI, selection layout,
and added support for selective topic expansion and click-to-expand.
- **Core Stability:** Improved sandbox reliability on Linux and Windows,
resolved shebang compatibility issues, and fixed various crashes in the CLI
and core services.
- **Refactored Subagents and Unified Tooling:** Consolidate subagent tools into
a single `invoke_subagent` tool, removed legacy wrapping tools, and improved
turn limits for codebase investigator.
- **Advanced Memory and Skill Management:** Introduced `/memory` inbox for
reviewing extracted skills and added skill patching support, enhancing agent
learning and persistence.
- **Expanded Test and Evaluation Infrastructure:** Added memory and CPU
performance integration test harnesses and generalized evaluation
infrastructure for better suite organization.
- **Sandbox and Security Hardening:** Centralized sandbox paths for Linux and
macOS, enforced read-only security for async git worktree resolution, and
optimized Windows sandbox initialization.
- **Enhanced CLI UX and UI Stability:** Improved scroll momentum, added a
`debugRainbow` setting, and resolved various memory leaks and PTY exhaustion
issues for a smoother terminal experience.
