v2.6.6

Reviewers no longer have to chase pending approvals one at a time. The Slack interface now supports multi-row approvals with all pause types covered, so a reviewer can resolve several pending approvals in one place without leaving the channel. Confirmations, user-input prompts, structured feedback, and external-execution steps all surface as interactive TaskCards, and each rejection still collects a reason where one applies and passes it back to the agent so it can adjust.

Wiring it up is mostly one decorator and a db (paused runs persist and resume by run_id):

from agno.agent import Agent
from agno.db.sqlite import SqliteDb
from agno.models.openai import OpenAIResponses
from agno.os import AgentOS
from agno.os.interfaces.slack import Slack
from agno.tools import tool


@tool(requires_confirmation=True)
def deploy_service(name: str) -> str:
    """Deploy a service. The run pauses for approval before this runs."""
    return f"Deployed {name}."


# A paused run persists to the database and resumes by run_id once the
# reviewer acts, so the Slack interface needs a db.
db = SqliteDb(db_file="tmp/approvals.db", session_table="agent_sessions")

agent = Agent(
    name="Ops Agent",
    id="ops-agent",
    model=OpenAIResponses(id="gpt-5.4"),
    tools=[deploy_service],
    db=db,
)

agent_os = AgentOS(
    agents=[agent],
    interfaces=[Slack(agent=agent, reply_to_mentions_only=True)],
)
app = agent_os.get_app()

if __name__ == "__main__":
    agent_os.serve(app="approvals:app", port=7777)
