🤖 👥 Agent Teams

The Datalayer orchestration extension

agent_teams.a2a implements the Datalayer orchestration extension — an optional A2A extension that lets a worker and an orchestrator say the things about delegated work that A2A leaves unsaid: which execution a delegation is part of and where it sits in its tree, a budget to decline before exceeding, a checkpoint to resume from, and instructions delivered to a turn already in progress.

from agent_teams.a2a import ExecutionRef, build_delegation_meta

meta = build_delegation_meta(
    ExecutionRef(execution_id="exec_1", root_execution_id="exec_1", depth=0),
    budget={"outputTokens": 4000},
)

Nothing here requires the rest of this package, and nothing here imports Datalayer's own platform — agent_teams.a2a.orchestration_extension is a standalone module built on fasta2a alone. A worker implementing none of it still runs; see the normative specification and its JSON Schema at docs/extension-v1.md for the full field-by-field contract this module implements.

This is distinct from agent_teams.a2a.extensions' own team-coordination extension (https://datalayer.io/ext/team-coordination/v1) — member assignment, task dependencies, health and reactions for a team's own internal coordination. The two extensions are independent and separately negotiated; a card may advertise either, both, or neither.
