- Issues
- Inter-agent communication / async subagent result injection lacks a dedicated message type
- Add OTel observability for silent message-history mutations (repair, sanitize, prepare_messages)
- Apply tool timeouts in `ToolManager` so all toolsets honor them
- Add `Workspace` access to agent runs
- Optional provenance for human-in-the-loop tool approvals over UI adapters (verify an approval maps to a real server-issued pause)
- [provider-mapping-sweep] bedrock: add citationsContent block / citation delta mapping (currently unmapped, not yet reachable via public API)
- Cancellation semantics: a level-triggered contract for agent runs, streams, tools, and durable execution
- Re-probe scheduled model shutdowns before removing model names
- Add first-class Codex subscription authentication
- Scope `MCPToolset` sessions to the entering context so concurrent callers don't share auth identity
