Agno v3.1.11 adds harness agents to teams and workflows and session search

Harness agents can now be team members or workflow steps, including inside Parallel, Loop, Condition and Router blocks. The team leader delegates to them with delegate_task_to_member, and each harness keeps its own model, tools, workspace and conversation across turns of a session. A harness agent with sandbox= runs each turn in its own container.

The release adds GET /sessions/filter-schema and POST /sessions/search, which accept nested AND, OR and NOT filters on session name, IDs, session type and timestamps. Filters are applied before counting and pagination in PostgreSQL and SQLite, and sync and async client methods are included. Company Tasks can now be created in Backlog, Ready or Cancelled, and new Routine endpoints cover cancel, archive, restore and admin-only delete.

Bug fixes cover ReaderFactory returning a fresh reader for each call, StepOutput.to_dict() preserving non-string values, HuggingFace parameter mapping, timezone handling in Google Calendar slot search, and archived Tasks no longer blocking Project or Product archiving. AgentOSClient's continue_agent_run no longer accepts the non-existent stream argument; developers should use continue_agent_run_stream instead.

Developers can now compose Claude Code and Codex agents into Agno teams and workflows instead of wrapping them separately.

Code that passed a stream argument to continue_agent_run will need to switch to continue_agent_run_stream.

Session search filters run in the database before pagination, so large session lists can be queried without loading every record first.
