dag-coordination

协调从建筑师计划开始的 DAG 执行生命周期。适用于建筑师下达执行计划、运行中的 DAG 需要修改或取消，或需要监控 DAG 进度时使用。涵盖 execute_dag、cancel_dag、modify_dag 以及 query_dag_status 技能。

name: dag-coordination
description: Coordinate DAG execution lifecycle from architect plans. Use when the architect dispatches a plan for execution, when a running DAG needs modification or cancellation, or when DAG progress needs monitoring. Covers execute_dag, cancel_dag, modify_dag, and query_dag_status skills.

DAG Coordination

Manage the full lifecycle of architect plan execution through the DAG scheduler.

Capabilities

  • •Execute DAGs from architect plan dispatch (via bus or direct skill invocation)
  • •Cancel running DAGs with reason tracking
  • •Modify running DAGs mid-flight (add/remove nodes) at architect request
  • •Query DAG status from the live scheduler or historical SQLite store
  • •Recover incomplete DAGs after crash via WAL replay

Decision framework

DAG execution request

  1. •Execute via execute_dag with the plan's DAG JSON
  2. •Monitor progress via query_dag_status
  3. •Query pipeline agent buffers via query_buffer for per-task detail
  4. •On completion or failure, broadcast status

DAG modification

  1. •Apply via modify_dag with the architect's modification payload
  2. •Monitor the modified DAG for stability via query_dag_status

DAG failure

  1. •Query status via query_dag_status
  2. •Query task buffers for failed nodes via query_buffer
  3. •Escalate to architect with failure context via escalate_to_architect
