From ee45a1626787126f4ff666e239b5f056c49cf57d Mon Sep 17 00:00:00 2001 From: Manus AI Date: Sat, 21 Feb 2026 13:42:31 -0500 Subject: [PATCH] feat(swarm): add in-process agent spawning with live auction bidding MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add spawn_in_process_agent() to SwarmCoordinator: creates lightweight SwarmNode instances that share the coordinator's comms layer and AuctionManager, enabling synchronous bid submission - Fix post_task() to open the auction BEFORE announcing via comms so in-process agent callbacks can submit bids into an open auction - Fix run_auction_and_assign() to close an already-open auction instead of re-opening (which would discard bids) - Add POST /swarm/tasks/auction route for atomic task+auction flow - Add 7 integration tests (TDD) covering the full lifecycle: spawn → post → auction → assign → complete --- src/dashboard/routes/swarm.py | 15 +++++ src/swarm/coordinator.py | 67 +++++++++++++++++++- tests/test_swarm_integration.py | 108 ++++++++++++++++++++++++++++++++ 3 files changed, 187 insertions(+), 3 deletions(-) create mode 100644 tests/test_swarm_integration.py diff --git a/src/dashboard/routes/swarm.py b/src/dashboard/routes/swarm.py index 8d3f944..8727368 100644 --- a/src/dashboard/routes/swarm.py +++ b/src/dashboard/routes/swarm.py @@ -88,6 +88,21 @@ async def post_task(description: str = Form(...)): } +@router.post("/tasks/auction") +async def post_task_and_auction(description: str = Form(...)): + """Post a task and immediately run an auction to assign it.""" + task = coordinator.post_task(description) + winner = await coordinator.run_auction_and_assign(task.id) + updated = coordinator.get_task(task.id) + return { + "task_id": task.id, + "description": task.description, + "status": updated.status.value if updated else task.status.value, + "assigned_agent": updated.assigned_agent if updated else None, + "winning_bid": winner.bid_sats if winner else None, + } + + @router.get("/tasks/{task_id}") async def get_task(task_id: str): """Get details for a specific task.""" diff --git a/src/swarm/coordinator.py b/src/swarm/coordinator.py index 74a2bfd..507e449 100644 --- a/src/swarm/coordinator.py +++ b/src/swarm/coordinator.py @@ -35,6 +35,7 @@ class SwarmCoordinator: self.manager = SwarmManager() self.auctions = AuctionManager() self.comms = SwarmComms() + self._in_process_nodes: list = [] # ── Agent lifecycle ───────────────────────────────────────────────────── @@ -57,20 +58,80 @@ class SwarmCoordinator: def list_swarm_agents(self) -> list[AgentRecord]: return registry.list_agents() + def spawn_in_process_agent( + self, name: str, agent_id: Optional[str] = None, + ) -> dict: + """Spawn a lightweight in-process agent that bids on tasks. + + Unlike spawn_agent (which launches a subprocess), this creates a + SwarmNode in the current process sharing the coordinator's comms + layer.
