PowerX (ops) - Plugin Workflow Closure Verification

Usecase Overview

• Business Goal: After task execution, trigger complex business actions through plugin workflows, complete notifications, reconciliation, approvals and other closures, generating traceable delivery reports.
• Success Metrics: Closure pass rate ≥98%; notification/reconciliation failures trigger remediation within 2 minutes; monitoring and audit record coverage 100%.
• Scenario Linkage: Corresponds to Stage 4「Workflow Closure & Reporting」, key to task delivery value and compliance traceability.

Through closure validation and remediation strategies, ensure every task provides clear outcomes and audit traces, avoiding "execution completed but business unaware".

Context & Assumptions

• Prerequisites
  • Plugin workflows support traceable node status, receipts and remediation interfaces.
  • workflow-trigger-kit and closure-verification Feature Flags enabled.
  • Monitoring panels and audit warehouse have write permissions.
  • Notification channels (email/IM/Webhook) configured.
• Inputs/Outputs
  • Input: Task execution results, workflow trigger parameters, reconciliation/notification policies, tenant and user context.
  • Output: Plugin workflow execution status, closure validation results, remediation tasks, user/ops notifications, audit reports.
• Boundaries
  • Does not cover implementation details of each workflow node within plugins.
  • Not responsible for cross-system fund settlement, only provides reconciliation validation interfaces.

Solution Blueprint

System Decomposition

Module	Responsibility	Description
Workflow Trigger	Invoke plugin or external workflows	Support sync/async triggering, parameter mapping, idempotency keys.
Closure Validator	Validate receipts, reconciliation, notification results	Check mandatory nodes and determine success/failure levels.
Remediation Orchestrator	Trigger remediation processes or human approval	Resend notifications, rebuild tasks, escalate to human.
Reporting Builder	Aggregate execution, closure, remediation logs and generate reports	Output to users, Ops, and audit systems.
Metrics & Alerting	Collect closure metrics, set thresholds	Trigger Grafana/Slack alerts.

Process & Sequence

1. Step 1 – Workflow Trigger: Main Agent calls Workflow Trigger, converts execution results to plugin workflow input with reconciliation/notification policies.
2. Step 2 – Status Callback: Plugin nodes execute approval, writing, notification and return workflow.callback events or polling interfaces.
3. Step 3 – Closure Validation: Closure Validator checks if all mandatory nodes succeed, including notification receipts, data reconciliation, balance consistency.
4. Step 4 – Remediation or Closure: If validation fails, Remediation Orchestrator triggers remediation; if success, generate delivery report and notify users.
5. Step 5 – Metrics & Audit: Metrics module writes closure metrics, Audit builds reports and archives.

• Inbound: POST /internal/agent/workflow/trigger; EVENT agent.task.completed (carrying task output).
• Outbound: POST /plugins/{pluginId}/workflow; EVENT plugin.workflow.completed; POST /notifications/agent-delivery; EVENT agent.workflow.closure.failed; POST /audit/agent-closure-report.
• Configuration/Scripts: config/agent/workflow_templates/*.yaml, config/agent/closure_rules.yaml, scripts/ops/closure-validation.mjs.

Implementation Checklist

Item	Description	Status	Owner
Workflow templates	Template library for common tasks (reports, notifications, approvals)	[ ]	Plugin Guild
Closure rules	Mandatory nodes, reconciliation logic, notification matrix configuration	[ ]	Agent Platform Guild
Remediation strategy	Resend, human confirmation, escalation alert process scripts	[ ]	Ops Reliability Center
Report generation	Delivery reports, audit attachments, user notifications	[ ]	Agent Platform Guild
Metrics+Alerts	plugin.workflow.closure_rate, remediation count	[ ]	Ops Reliability Center

Testing Strategy

• Unit: Workflow trigger parameter mapping, closure rule engine, remediation strategy selection.
• Integration: Integrate with report/notification plugins, verify sync and async receipt paths; simulate reconciliation failure trigger remediation.
• End-to-End: Execute complete tasks (reports+notifications), check closure events, user notifications, audit reports.
• Disaster: Simulate plugin callback delays, notification failures, reconciliation differences, confirm remediation and alerts take effect.

Observability & Ops

• Metrics: plugin.workflow.closure_rate, agent.workflow.remediation_total, agent.workflow.callback_latency, agent.workflow.audit_delay.
• Logs: Record workflow_id, required_nodes, closure_status, remediation_action, user_notified.
• Alerts: 3 consecutive closure failures, remediation time >5 minutes, audit report write failure; push to Ops on-call and business owners.
• Dashboard: Grafana「Agent Closure」, Ops closure board, Audit report warehouse.

Rollback & Failure Handling

• Workflow trigger deployment supports blue-green; rollback and pause new templates if new version fails.
• Callback timeout can switch to polling or directly trigger remediation.
• When report generation fails, preserve original data and mark task as "pending supplement".

Follow-ups & Risks

Risk	Impact	Mitigation	ETA
Inconsistent plugin callback protocols	Closure validation difficulties	Define standard callback schema and provide adapters	2025-03-12
Reconciliation logic not aligned with financial systems	False positives/negatives	Define reconciliation fields with financial interfaces and gray-validate	2025-03-20
