Pre-check: Aliyun CLI >= 3.3.1 required

Run

aliyun version

to verify the version is 3.3.1 or higher. If not installed or the version is too low, see

references/cli-installation-guide.md

for installation instructions.

[MUST] Then run

aliyun configure set --auto-plugin-install true

to enable automatic plugin installation.

Pre-check: Alibaba Cloud Credentials Required

Security Rules:

• NEVER read, echo, or print AK/SK values (e.g.,

  echo $ALIBABA_CLOUD_ACCESS_KEY_ID

  is FORBIDDEN)
• NEVER ask the user to input AK/SK directly in the conversation or command line
• NEVER use

  aliyun configure set

  with literal credential values
• ONLY use

  aliyun configure list

  to check credential status

bash

aliyun configure list

Check the output for a valid profile (AK, STS, or OAuth identity).

If no valid profile exists, STOP here.

1. Obtain credentials from Alibaba Cloud Console
2. Configure credentials outside of this session (via

   aliyun configure

   in a terminal or environment variables in a shell profile)
3. Return and retry after

   aliyun configure list

   shows a valid profile

references/ram-policies.md

[MUST] Permission Failure Handling: When any command or API call fails due to permission errors at any point during execution, follow this process:

1. Read

   references/ram-policies.md

   to get the full list of permissions required by this skill
2. Use the

   ram-permission-diagnose

   skill to guide the user through requesting the necessary permissions
3. Pause and wait until the user confirms that the required permissions have been granted

IMPORTANT: Parameter Confirmation — Before executing any command or API call, ALL user-customizable parameters (e.g., RegionId, instance names, CIDR blocks, passwords, domain names, resource specifications, etc.) MUST be confirmed with the user. Do NOT assume or use default values without explicit user approval.

How to get WorkspaceId: If the user doesn't know their workspace ID, run:

bash

aliyun aiworkspace list-workspaces --region <region> --user-agent AlibabaCloud-Agent-Skills

This returns all workspaces the user has access to. Select the appropriate one based on

WorkspaceName

or ask the user to confirm.

Reference: Create and Manage Workspaces

Full command syntax and parameter details:

references/related-commands.md

.

Every

aliyun

CLI command must include

--user-agent AlibabaCloud-Agent-Skills

.

aliyun pai-dsw list-ecs-specs --accelerator-type <CPU|GPU> --region <region>

[MUST] Region confirmation: The

--region

parameter is required. Spec availability varies by region — always confirm the region with the user before querying.

[MUST] Determine accelerator type correctly:

• User mentions a spec name (e.g.,

  ecs.hfc6.10xlarge

  ): Query BOTH CPU and GPU types, then match

  InstanceType

  in results. Use the returned

  AcceleratorType

  field to confirm the classification.
• User specifies image type: GPU image URL (contains

  -gpu-

  or

  cu

  ) → query GPU specs; CPU image URL → query CPU specs.
• User describes use case only: GPU for 大模型训练/深度学习, CPU for 数据分析/轻量任务. Always confirm with user if ambiguous.
• [IMPORTANT] Do NOT guess from spec name prefix — the naming convention is unreliable. Always verify via API response.

[MUST] Choose accelerator type based on user requirements:

• Default recommendation: GPU for 大模型训练/深度学习, CPU for 数据分析/轻量任务
• Match image type (strong indicator): If user specifies a GPU image URL (contains

  -gpu-

  or

  cu

  ), query GPU specs. If CPU image, query CPU specs.
• Spec name requires verification: If user mentions a spec name, query both types and find the match in results
• Always confirm with user before querying if the use case is ambiguous and no spec name is provided

• InstanceType

  : Spec name (e.g.,

  ecs.hfc6.10xlarge

  )

• AcceleratorType

  :

  CPU

  or

  GPU

  — the actual classification from API

• IsAvailable

  : PRIMARY indicator —

  true

  means the spec is available for pay-as-you-go/subscription

• SpotStockStatus

  : SECONDARY indicator — only for spot instances:

  WithStock

  (available) or

  NoStock

  (unavailable)

• CPU

  /

  Memory

  /

  GPU

  /

  GPUType

  : Hardware details

• Price

  : Hourly price in CNY

[MUST] Availability check logic:

• For pay-as-you-go/subscription: Check

  IsAvailable == true

• For spot instances: Check

  IsAvailable == true

  AND

  SpotStockStatus == "WithStock"

• DO NOT use

  SpotStockStatus

  alone to judge availability — many specs have

  IsAvailable: true

  but

  SpotStockStatus: "NoStock"

• Example:

  ecs.hfc6.10xlarge

  with

  IsAvailable: true, SpotStockStatus: "NoStock"

  → Available for pay-as-you-go

[MUST] Idempotency guarantee: The CreateInstance API does not support ClientToken, so idempotency is ensured via a check-then-act pattern. Before creating, you must call

list-instances --instance-name <name>

to check if the name already exists.

aliyun pai-dsw list-instances \
  --instance-name <name> \
  --region <region> \
  --resource-id ALL \
  --user-agent AlibabaCloud-Agent-Skills

• TotalCount == 0

  → Name is available, proceed to Step 2.2 to create

• TotalCount >= 1

  → [MUST] Verify exact name match:
  1. Iterate through the returned

     Instances

     array
  2. For each instance, compare its

     InstanceName

     field with the target name character by character (case-sensitive, exact string match)
  3. Exact match found (

     instance.InstanceName === targetName

     ) → Name already exists:
     • Extract the

       InstanceId

       from the matching instance
     • Call

       get-instance --instance-id <id>

       to get full details
     • Compare key parameters (

       EcsSpec

       ,

       ImageUrl

       ,

       Accessibility

       , etc.)
     • Match → Return the existing

       InstanceId

       , do not recreate
     • Mismatch → Ask user to choose a different name
  4. No exact match found (no instance has

     InstanceName === targetName

     ) → Name is available, proceed to Step 2.2 to create

[WARNING] Critical: Exact name match required

The

--instance-name

filter may return partial matches. For example:

• Query:

  --instance-name llm_train_001

• Response may include:

  llm_train_001

  ,

  llm_train_001_v2

  ,

  llm_train_001_backup

You MUST verify exact match by checking:

for instance in response.Instances:
    if instance.InstanceName == targetName:  # EXACT string equality
        # Name already exists - DO NOT create

Do NOT assume name is available just because

TotalCount > 0

but you "think" no exact match. If

TotalCount >= 1

, carefully check each instance's InstanceName field.

aliyun pai-dsw create-instance

--workspace-id

--instance-name

--ecs-spec

--region

--image-url

--image-id

[MUST] Region confirmation: The

--region

parameter is required and must be confirmed with the user. Do NOT use CLI default region without explicit user approval. Spec availability and pricing vary by region.

[MUST] Match EcsSpec with image type:

• GPU image URL (contains

  -gpu-

  or

  cu

  ) → Must select a GPU spec (e.g.,

  ecs.gn6v-c4g1.xlarge

  )
• CPU image URL (contains

  -cpu-

  ) → Must select a CPU spec (e.g.,

  ecs.c6.large

  )
• The spec type MUST match the image type, otherwise the instance will fail to start
• Use case (大模型训练/数据分析) is only a recommendation, image type is the definitive indicator

Dataset mounting (optional): If the user specifies a dataset to mount, use the

--datasets

parameter in CLI list format:

bash

--datasets DatasetId=<dataset-id> MountPath=<mount-path> MountAccess=RO

[MUST] Dataset parameters require explicit user confirmation — do NOT assume or auto-generate dataset configurations.

{"InstanceId": "dsw-xxxxx", ...}

[IMPORTANT] Return immediately after creation: After

create-instance

returns

InstanceId

, do NOT block waiting for

Running

status. Instead:

1. Return the

   InstanceId

   and current status (

   Creating

   ) to the user immediately
2. Provide the user with a command to check status later:
   bash

   aliyun pai-dsw get-instance --instance-id <instance-id> --user-agent AlibabaCloud-Agent-Skills

3. Inform the user that instance startup typically takes 2–5 minutes

Why this matters: Blocking polling prevents the agent from responding to other user requests. DSW instance creation is a long-running operation; the agent should return control to the user promptly.

aliyun pai-dsw get-instance --instance-id <id>

When to poll: Only poll when the user explicitly asks to wait for a status change (e.g., "wait until it's running"). Otherwise, return the current status immediately.

Timeout limits: Maximum 60 polls (30 minutes total). If exceeded, stop and prompt user to check manually.

Polling interval: 10–30 seconds between calls.

CLI timeout: For long-running operations, increase read timeout:

bash

aliyun pai-dsw get-instance --instance-id <id> --read-timeout 30 --user-agent AlibabaCloud-Agent-Skills

Once

Status == "Running"

, access the instance via

InstanceUrl

.

For complete status transitions, see Instance Status Values in

references/related-commands.md

.

aliyun pai-dsw stop-instance --instance-id <id>

Status transition:

Running

→

Stopping

→

Stopped

Save environment image: To save the environment as a custom image before stopping, use the PAI Console. See Create a DSW Instance Image for instructions.

aliyun pai-dsw update-instance --instance-id <id>

--instance-name

--ecs-spec

--image-id

--accessibility

--datasets

[MUST] Before updating:

1. Call

   get-instance

   to check current status and configuration
2. Check if update is needed:
   • For

     --ecs-spec

     : Compare current

     EcsSpec

     with target spec. If already equal, skip update and inform user
   • For

     --image-id

     /

     --image-url

     : Compare current

     ImageId

     /

     ImageUrl

     with target
   • For

     --instance-name

     : Compare current

     InstanceName

     with target
3. If already at target configuration, return current instance info — do not call update-instance
4. If update is needed, use

   --start-instance true

   to auto-start after update

[IMPORTANT] Always update the specified instance by its

InstanceId

. Do NOT substitute with another instance that already has the target spec — the user's request is to upgrade the specific instance, not to find an alternative.

aliyun pai-dsw start-instance --instance-id <id>

Running

Prerequisite: Instance must be in

Stopped

or

Failed

state. Call

get-instance

to confirm before starting.

This skill does not expose instance deletion (irreversible operation — use the console).

To stop incurring charges, stop the instance via Step 5 (

stop-instance

).

1. Always run check-then-act before creation — use

   list-instances --instance-name <name>

   to avoid duplicate-instance errors.
2. Prefer

   PRIVATE

   visibility — prevents accidental operations by other workspace users.
3. Check instance status before update — call

   get-instance

   first; some parameters require Stopped state, others can be updated while Running.
4. Use

   --resource-id ALL

   with

   list-instances

   — the default only returns post-paid instances.
5. Observe polling timeout limits — see Step 4 for timeout and interval guidance.
6. Verify spec availability before provisioning — run

   list-ecs-specs

   to confirm the spec is available in the target region.
7. Tag instances with Labels — simplifies batch queries and lifecycle management.
