- **Context Management:** Introduced a Context Compression Service to optimize - **Refactored Subagents and Unified Tooling:** Consolidate subagent tools into
context window usage and landed a background memory service for skill a single `invoke_subagent` tool, removed legacy wrapping tools, and improved
extraction. turn limits for codebase investigator.
- **Enhanced Security:** Implemented context-aware persistent policy approvals - **Advanced Memory and Skill Management:** Introduced `/memory` inbox for
for smarter tool permissions and enabled `web_fetch` in plan mode with user reviewing extracted skills and added skill patching support, enhancing agent
confirmation. learning and persistence.
- **Workflow Monitoring:** Added background process monitoring and inspection - **Expanded Test and Evaluation Infrastructure:** Added memory and CPU
tools for better visibility into long-running tasks. performance integration test harnesses and generalized evaluation
- **UI/UX Refinements:** Enhanced the tool confirmation UI, selection layout, infrastructure for better suite organization.
