Usecase Overview

• Business Goal: Automatically match strategies when the Agent receives specific business events, generate taskflows that invoke plugins or external APIs, and keep execution observable and auditable with minimal manual intervention.
• Success Metrics: Strategy hit rate ≥ 80%; taskflow generation latency ≤ 10 seconds; automated execution success rate ≥ 95%; manual intervention rate < 10%; audit log completeness 100%.
• Scenario Alignment: "Supports Stage 3 of SCN-OPS-EVENT-TASKFLOW-001, linking event notifications and scheduling, while providing context for retry/recovery flows."

Strategy-driven Agent orchestration enables event-triggered automation across reporting, notification, and approval chains.

Context & Assumptions

• Prerequisites
  • Feature flags agent-orchestrator, agent-strategy-library, and audit-streaming are enabled.
  • Agent services run with high availability and provide strategy libraries, variable templates, and permission checks.
  • The event bus delivers standardized payloads with tenant identifiers, context, and idempotency keys.
  • Downstream plugins/APIs support idempotent calls, trace propagation, and asynchronous status callbacks.
• Inputs / Outputs
  • Inputs: "Subscribed events (for example, plugin.job.completed, tenant.request.pending), strategy configuration, context variables, tenant and permission metadata."
  • Outputs: Generated taskflows (nodes, dependencies, parameters), execution outcomes, audit records, manual approval tasks or alerts.
• Boundaries
  • Excludes strategy-authoring IDEs or simulators (covered by separate standards).
  • Does not manage credential provisioning for external systems—assumes pre-configured credentials.
  • Long-running manual workflows are overseen by operations systems outside this usecase.

Solution Blueprint

Architecture Layers

Layer	Key Modules	Responsibility	Code Entry
Event Listener	internal/agent/subscribers/event_listener.go	Subscribe to events, assemble context, enforce idempotency	services/agent/subscribers
Strategy Evaluation	internal/agent/strategy/matcher.go	Match strategies, validate conditions, compute variables	services/agent/strategy
Orchestration Builder	internal/agent/orchestrator/workflow_builder.go	Construct task nodes, dependencies, and parameter injection	services/agent/orchestrator
Node Execution	internal/agent/executor/node_runner.go	Execute nodes, manage retries, write back status	services/agent/executor
Visualization	pkg/ops/agent_insight_reporter.go	Produce orchestration views, metrics, and audit events	pkg/ops

Flow & Sequence

1. Step 1 – Event Intake: The Agent validates tenant scope, ensures idempotency, and builds the context dictionary.
2. Step 2 – Strategy Matching: The strategy engine evaluates event type, conditions, and weights to pick the correct strategy and merge parameter templates.
3. Step 3 – Taskflow Construction: The workflow builder generates sequential/parallel nodes, dependencies, and callback policies.
4. Step 4 – Node Execution: The node runner invokes plugins/APIs, handles success/failure/delay, updates state, and emits audit trails.
5. Step 5 – Feedback & Escalation: Unmatched or repeatedly failing workflows create manual review tasks and notify responsible owners.

Contracts & Interfaces

• Inbound APIs / Events
  • EVENT plugin.job.completed, EVENT tenant.request.pending — include tenant, job ID, and contextual payload.
  • POST /internal/agent/events — Manual replay endpoint requiring signature and idempotency validation.
• Outbound Calls
  • POST /plugin/runtime/{pluginId}/execute — Invoke plugin automation with strategy context.
  • POST /notifications/agent-task — Notify stakeholders about created or failed tasks.
  • POST /ops/manual-review — Generate manual review work orders.
• Configs & Scripts
  • config/agent/strategies/*.yaml — Strategy definitions and templates.
  • scripts/ops/agent-strategy-test.mjs — Strategy unit tests and simulation tool.
  • scripts/ops/agent-replay.mjs — Event replay and troubleshooting script.

Implementation Checklist

Item	Description	Status	Owner
Strategy Library	Implement DSL, condition parsing, version control	[ ]	Eva Zhang
Idempotency Governance	Generate idempotency keys, caching, expiry policies	[ ]	Matrix Ops
Orchestration Builder	Create taskflow templates, dependency parsing, variable injection	[ ]	Eva Zhang
Observability	Emit metrics, orchestration views, audit logs, alerts	[ ]	Matrix Ops
Manual Escalation	Integrate Ops work orders/notifications with approval flow	[ ]	Eva Zhang

Testing Strategy

• Unit: Strategy matching, condition combinations, variable substitution, idempotency cache, node state machine.
• Integration: Run C-1 to validate automated report generation upon events; run C-2 to confirm unmatched strategies enter manual review.
• End-to-End: Drive diverse sandbox events to inspect orchestration views, Ops console status, and notifications; simulate retry and manual takeover.
• Non-functional: Load test at 200 TPS event ingestion; inject failures in strategy library or downstream APIs to verify graceful degradation and alerting.

Observability & Ops

• Metrics: "agent.strategy.hit_rate, agent.workflow.generated_total, agent.node.success_total, agent.manual_escalation_total, agent.workflow.latency_p95."
• Logging: "Capture event_id, strategy_id, workflow_id, node_id, status, duration, escalation_reason; redact sensitive data."
• Alerts: Strategy miss rate > 20% over 15 minutes, automated failure rate > 10%, manual backlog > 20 items; notify via Slack/PagerDuty.
• Dashboards: "Grafana Runtime Ops / Agent Automation, Datadog agent.*, Ops console orchestration view."

Rollback & Failure Handling

• Rollback Steps: "Revert strategy library and Agent service, disable agent-orchestrator, and clean up active workflows."
• Mitigations: "Use agent-replay.mjs to replay critical events, manually trigger required tasks, and fill in execution outcomes."
• Data Repair: "Validate agent_workflows table, fix orphaned nodes, and regenerate audit traces."

Follow-ups & Risks

Risk / Item	Impact	Mitigation	Owner	ETA
No rollback or regression for strategies	Widespread workflow failures	Introduce strategy approval and rollback mechanism	Eva Zhang	2025-11-10
Agent execution permissions incomplete	Potential over-privileged actions	Integrate with permission system, enforce least privilege	Matrix Ops	2025-11-18
