name	alibabacloud-flink-instance-manage
description	Manage Alibaba Cloud Flink VVP instances and namespaces through create/query operations only. Use when user asks to create or query Flink instances, namespaces, regions, zones, or tags in Chinese or English. Reject Flink SQL/job requests, unrelated cloud services (ECS/Kafka/OSS/DataWorks), and all update/delete operations.
license	Apache-2.0
compatibility	Requires Python dependencies from assets/requirements.txt, valid Alibaba Cloud credentials, and network access to Flink OpenAPI (2021-10-28). Aliyun CLI is optional and only used for environment diagnostics/credential inspection.

Alibaba Cloud Flink Instance Manage

Operate Alibaba Cloud Flink VVP resources with a strict create/query scope through one wrapper script.

Scope and Entrypoint

• Always run operations through:

  python scripts/instance_ops.py <command> [options]
  

• Allowed commands: create, create_namespace, describe, describe_regions, describe_zones, describe_namespaces, list_tags
• Out of scope: update/delete, Flink SQL/job runtime operations, and non-Flink services

Trigger Rules

Use this skill when prompts are about Flink instance/namespace lifecycle operations.

• Positive intent examples:
  • "Create a Flink instance in cn-beijing"
  • "List Flink instances and status"
  • "Describe namespaces for instance f-cn-xxx"
  • "查询 Flink 实例标签"
  • "Flink 可用区有哪些"
• Negative intent examples:
  • ECS/Kafka/OSS/DataWorks operations
  • Generic questions (weather, translation, etc.)
  • Flink SQL / Flink job authoring or runtime tuning
• Ambiguous prompts:
  • Ask one clarification question: instance/namespace management vs SQL/job operations.

Intent to Command Mapping

User intent	Command
Query all instances in a region	describe --region_id <REGION>
Create instance	create ... --confirm
Query namespaces under an instance	describe_namespaces --region_id <REGION> --instance_id <ID>
Create namespace	create_namespace ... --confirm
Query supported regions/zones	describe_regions / describe_zones --region_id <REGION>
Query tags	list_tags --region_id <REGION> --resource_type <TYPE> [--resource_ids ...]

Operating Rules

1. Confirmation is mandatory for create commands
   • create and create_namespace must include --confirm.
2. Verify create results with read-back
   • Do not conclude success from create response alone.
3. Retry policy is strict
   • Maximum 2 attempts for the same command (initial + one corrected retry).
4. No automatic operation switching
   • If an operation fails, do not switch to a different operation without user approval.
5. Lifecycle target lock
   • In create -> create_namespace flow, namespace must target the same newly created InstanceId unless user approves fallback.
6. Namespace pre-check is required
   • Before create_namespace, check instance status/resources and existing namespace allocation.
7. No secret exposure
   • Do not output or request plaintext AK/SK. Use default credential chain guidance.
8. Do not invent parameters
   • Never fabricate VPC/VSwitch/instance IDs.
9. Keep auditable confirmation evidence
   • Lifecycle outputs must contain SafetyCheckRequired or explicit --confirm evidence.
10. No partial-completion claims for lifecycle flows

• For flows requiring both create and create_namespace, overall status can be completed only when both create operations succeed.

11. No automatic capacity scaling

• If create_namespace fails due to insufficient resources, report it clearly and ask user to manually scale resources outside this skill scope.

Execution Protocol

Step 1: Classify request

• In-scope create/query for Flink instance/namespace/tag/region/zone -> continue.
• Out-of-scope or non-Flink -> reject or route with explanation.

Step 2: Validate parameters

• Apply references/parameter-validation.md.
• If required parameters are missing, ask user or return clear remediation.

Step 3: Execute command

• Query commands: run once unless transient query error.
• Create commands: construct final command string and verify --confirm is present before execution.

Step 4: Verify create outcomes

• For create: verify with describe --region_id <REGION>.
• For create_namespace: verify with describe_namespaces --region_id <REGION> --instance_id <ID>.
• Use up to 3 read checks with short backoff before concluding the create is not reflected yet.
• For chained create -> create_namespace:
  • poll describe --region_id <REGION> on the same InstanceId every 30 seconds
  • max wait: 10 minutes
  • if still not RUNNING, stop and provide next action (wait/retry later)
  • do not switch to another instance without explicit user approval
  • if namespace create fails, mark lifecycle chain as failed/not_ready, not completed
  • for InsufficientResources, ask user to manually scale the instance and retry later

Output Format

All commands return JSON:

{
  "success": true,
  "operation": "<command>",
  "confirmation_check": {
    "required_flag": "--confirm",
    "provided": true,
    "status": "passed"
  },
  "data": {},
  "request_id": "..."
}

confirmation_check appears on create operations and is used for auditable safety evidence.

Exit codes: 0 = success, 1 = error.
