PAI ResourceGroup Management#

Observability (MUST follow for every aliyun command)#

Upon loading this skill, generate a random session ID (32-char hex string) once for the entire session. Use it as {session-id} below.

Rule: Every aliyun CLI command that calls a cloud API MUST include the --user-agent flag. Local utility commands (e.g. configure, plugin, version) do not support this flag and should be excluded.

text

--user-agent AlibabaCloud-Agent-Skills/alibabacloud-pai-resource-group-management/{session-id}

Example (assuming session-id is a]1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6):

bash

aliyun ecs describe-instances --biz-region-id cn-hangzhou --user-agent AlibabaCloud-Agent-Skills/alibabacloud-pai-resource-group-management/a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6

Do not skip, alter the format, or omit --user-agent on any aliyun command invocation.

Business API commands ONLY: aliyun paistudio list-resource-groups, aliyun paistudio get-resource-group, aliyun paistudio create-resource-group, aliyun paistudio update-resource-group, aliyun paistudio delete-resource-group, aliyun paistudio list-resource-group-machine-groups, aliyun paistudio get-resource-group-machine-group, etc.

MUST NOT be added to system / configuration commands: aliyun configure list, aliyun configure get, aliyun plugin update, aliyun plugin list, aliyun version. These are local CLI utilities, not business API calls, and do not accept --user-agent.

1. Scenario Description#

Manage the full lifecycle of Alibaba Cloud PAI ResourceGroups (resource pools) via the aliyun paistudio CLI plugin: list / get / create / update / delete ResourceGroups (ECS general computing or Lingjun GPU), read-only inspection of attached MachineGroups, and bind/unbind UserVpc. ResourceGroups are the source of capacity that Quotas later carve up.

⚠️ Metrics APIs Deprecated: get-resource-group-total, get-resource-group-request, get-user-view-metrics, get-node-metrics are all deprecated and NOT supported by this skill.

🚫 MachineGroup deletion / release is OUT OF SCOPE. The agent is STRICTLY FORBIDDEN from invoking delete-resource-group-machine-group or delete-machine-group under any circumstance. Direct users to the PAI Console (BSS purchase / release flow). See references/not-implementable.md.

Architecture: PAI ResourceGroup → MachineGroup(s) → Node(s) with optional UserVpc (VpcId + SwitchId + SecurityGroupId) binding. ECS general-computing ResourceGroups may bind to any user VPC; Lingjun VPC is managed at the Lingjun infrastructure layer.

2. Installation & Auth#

• Aliyun CLI ≥ 3.3.3 with paistudio plugin — see references/cli-installation-guide.md.
• The agent NEVER reads / echoes / writes AK/SK. Verify only via aliyun configure list; if unconfigured, instruct the user to run aliyun configure themselves.

3. Environment Variables#

EnvRequiredNotesREGION_IDYese.g. cn-shanghai, cn-hangzhou, cn-wulanchabu (Lingjun).RESOURCE_GROUP_IDWhen operating on a specific RGObtained from list-resource-groups.MACHINE_GROUP_IDWhen operating on a specific MGObtained from list-resource-group-machine-groups.

4. RAM Policy#

See references/ram-policies.md for full read-only and read-write policy JSON. Minimum read scope:

json

{
  "Version": "1",
  "Statement": [{
    "Effect": "Allow",
    "Action": [
      "pai:GetResourceGroup", "pai:ListResourceGroups",
      "pai:GetMachineGroup", "pai:GetResourceGroupMachineGroup",
      "pai:ListResourceGroupMachineGroups"
    ],
    "Resource": ["acs:pai:*:*:resourcegroup/*"]
  }]
}

Permission failure handling: see references/validation-rules.md §5.

5. Parameter Confirmation#

Before invoking any mutating CLI command, the agent MUST print and confirm:

ParameterRequiredSource / ValidationDefaultRegionIdYesaliyun configure get region or env REGION_ID.NoneNameCreate / rename1-63 chars, kebab-case recommended. **Cannot be empty string on update.**NoneResourceTypeCreateEnum: ECS, Lingjun. ⚠️ ACS variants OFFLINE — see references/validation-rules.md §2 row C.ECS (if empty)VersionCreate (ECS only)Enum: 1.0, 2.0. ECS v2.0 forbids VPC on RG (VPC goes on Quota).1.0 (ECS default)UserVpc.VpcId / SwitchId / SecurityGroupIdIf binding VPC (ECS v1.0 only)All three required as a trio (PascalCase). Forbidden for ECS v2.0 / Lingjun. See references/validation-rules.md §3.NoneResourceGroupIdUpdate / delete / getObtained from list-resource-groups.NoneMachineGroupIdMG operationsObtained from list-resource-group-machine-groups.None

🚦 Pre-execution conflict matrix — before any aliyun paistudio … CLI (incl. --cli-dry-run), the agent MUST cross-check input against the matrix in references/validation-rules.md §2 (rows A-F: ECS v2.0+VPC, Lingjun+VPC, ACS variants, incomplete VPC trio, delete with attached MGs, MG deletion request). Any hit → corresponding branch (mostly Branch 1). Never pass-through to the backend and rely on backend errors.

Pre-execution discipline — three exclusive branches#

Before any mutating CLI call, the agent MUST classify the request into exactly one of three branches:

#BranchTriggerRequired output1**⚠️ Input Conflict**User input contradicts a design rule⚠️ Input Conflict block with 3 concrete options. No CLI call.2🛑 Precondition Not MetLive-state check fails🛑 Precondition Not Met block. No mutating CLI.3📋 Resolved PlanAll inputs valid, live state allows📋 Resolved Plan block; for update/delete also wait for CONFIRM <RG_NAME> token (name-priority).

Read-only list-* / get-* calls are exempt — execute directly, no block required.

🔒 Execution lock + literal-match self-check: branch block must be a standalone, user-visible segment with all required fields literally printed (no meta-statements like "now printing Resolved Plan"). Before any mutating CLI, the agent MUST scan the conversation for the literal 📋 Resolved Plan / 🛑 Precondition Not Met / ⚠️ Input Conflict header. Full rules and required fields per block: references/branch-discipline.md.

🔁 Multi-step / batch: N RG × M operations = N × M independent Resolved Plans + N × M CONFIRM tokens. A single CONFIRM ALL / CONFIRM batch token is forbidden. Full rules: references/branch-discipline.md Multi-step / batch operation rules.

🛑 Branch 1 silent-rewrite prohibition: never silently strip / coerce a conflicting input, never substitute the text block with AskUserQuestion / IDE widgets, never degrade to a verbal suggestion. Full rules: references/branch-discipline.md Branch 1 silent-rewrite prohibition.

Worked examples (5 cases, all branches + Lingjun refusal): references/branch-examples.md.

6. Core Workflow#

[MUST] Use the aliyun paistudio CLI exclusively. No raw HTTP, no SDK, no MCP tool, no console clicks, no internal endpoints. If the CLI does not expose a capability, treat it as not implementable ( references/not-implementable.md) — do not fall back to another transport.

[MUST] Observability — per-command --user-agent: see §0.

Confirmation Gate — HARD STOP (Create / Update / Delete)#

[CRITICAL — HIGHEST PRIORITY RULE]

The agent is ABSOLUTELY FORBIDDEN from executing create-resource-group, update-resource-group, or delete-resource-group in the same turn as the user's original request. These commands require a two-turn interaction:

Turn 1 (agent): Print the resolved plan / parameters, then print the confirmation prompt, then STOP. END THE TURN. DO NOT EXECUTE THE COMMAND. DO NOT PROCEED.

Turn 2 (user → agent): The user replies with the exact confirmation token. ONLY AFTER receiving this token in a separate user message may the agent execute the command.

If the agent executes create-resource-group, update-resource-group, or delete-resource-group without first receiving the confirmation token from the user in a prior turn, this is a critical workflow violation.

Mandatory dry-run before Update / Delete:

Before asking for the confirmation token, the agent MUST first execute the command with --cli-dry-run and show the output to the user. This is non-negotiable — no dry-run, no confirmation prompt, no execution. The sequence is:

1. Run <command> ... --cli-dry-run to preview the resolved request payload.
2. Show the dry-run output to the user.
3. Ask for the confirmation token.
4. STOP. END THE TURN.

Skipping the --cli-dry-run step is a critical workflow violation, equivalent to executing without confirmation.

Confirmation tokens:

• Create ( create-resource-group): CONFIRM-CREATE <RG_NAME> — print resolved parameters (Region, Name, ResourceType, Version, UserVpc if applicable), then ask: Type "CONFIRM-CREATE <RG_NAME>" to continue; any other input cancels. STOP HERE. END THE TURN. WAIT FOR USER INPUT.
• Update / Delete ( update-resource-group, delete-resource-group): CONFIRM <RG_NAME> — first run the command with --cli-dry-run, show the output, print the diff, then ask: Type "CONFIRM <RG_NAME>" (or the actual ResourceGroupId) to proceed; any other input cancels. STOP HERE. END THE TURN. WAIT FOR USER INPUT.

What "END THE TURN" means: The agent MUST finish its response after printing the confirmation prompt. It MUST NOT call create-resource-group / update-resource-group / delete-resource-group in that same response. The next action happens ONLY after the user sends a new message containing the exact token.

Read-only operations ( list-*, get-*) do NOT require this gate. Full rules: references/confirmation-gate.md.

Multi-Task Handling#

[CRITICAL] When the user requests multiple operations in one message: decompose into individual tasks, then process one mutating operation per turn. Each task follows its own Step 6.x workflow in full — no step may be skipped or combined. Each task needs its own 📋 Resolved Plan + its own confirmation token + its own turn. N RG × M operations = N × M tokens. The user's multi-step request is a TODO list, not a blanket execution authorization. Full rules + turn-by-turn example: references/confirmation-gate.md Multi-task and references/branch-discipline.md Multi-step / batch.

🚫 MachineGroup Deletion / Release — STRICTLY FORBIDDEN#

The agent MUST refuse aliyun paistudio delete-resource-group-machine-group and aliyun paistudio delete-machine-group under ALL circumstances, even with a CONFIRM <MACHINE_GROUP_ID> token. Direct the user to the PAI Console (Resource Pool → Machine Group → Unsubscribe / Release) or BSS OpenAPI for unsubscribe. Offer read-only inspection via Step 6.5 if helpful. Rationale: references/not-implementable.md.

Step 6.1 — List existing ResourceGroups#

bash

aliyun paistudio list-resource-groups \
  --region "${REGION_ID}" \
  --page-number 1 --page-size 20

Optional filters: --name, --resource-type ECS|Lingjun, --resource-group-ids "rg-xxx,rg-yyy", --has-resource true, --status, --versions, --computing-resource-provider, --sort-by GmtCreated --order desc.

Step 6.2 — Get a ResourceGroup detail#

bash

aliyun paistudio get-resource-group \
  --region "${REGION_ID}" \
  --resource-group-id "${RESOURCE_GROUP_ID}" \
  --is-ai-workspace-data-enabled true

Step 6.3 — Create a ResourceGroup [REQUIRES CONFIRMATION]#

[CRITICAL] Before create-resource-group, resolve every user-supplied parameter against references/validation-rules.md §2, print the resolved parameters in a 📋 Resolved Plan block, then ask for CONFIRM-CREATE <RG_NAME>. END THE TURN AND WAIT. Do NOT call create-resource-group until the user replies with the exact token in a subsequent message.

ABSOLUTELY FORBIDDEN: calling create-resource-group in the same turn as the user's request — even with --cli-dry-run, even with intervening thinking or tool calls. The CONFIRM-CREATE token MUST come from the user's next message, not from the agent's own continuation.

ECS Version Differences:

• ECS v2.0 ( --biz-version 2.0): VPC forbidden on RG (lives on Quota — see pai-quota-management).
• ECS v1.0 ( --biz-version 1.0 or omitted): VPC configurable on RG via --user-vpc (PascalCase trio required).

ECS v2.0 (no VPC):

bash

# ⚠️ ONLY execute AFTER receiving CONFIRM-CREATE token from the user in a SEPARATE TURN
aliyun paistudio create-resource-group \
  --region "${REGION_ID}" \
  --name "${RG_NAME}" \
  --resource-type ECS \
  --biz-version 2.0

ECS v1.0 with VPC binding (full PascalCase trio required — see references/validation-rules.md §3):

bash

# ⚠️ ONLY execute AFTER receiving CONFIRM-CREATE token from the user in a SEPARATE TURN
aliyun paistudio create-resource-group \
  --region "${REGION_ID}" \
  --name "${RG_NAME}" \
  --resource-type ECS \
  --user-vpc '{"VpcId":"vpc-xxx","SwitchId":"vsw-xxx","SecurityGroupId":"sg-xxx","DefaultRoute":"eth0","ExtendedCIDRs":["10.0.0.0/16"]}'

Lingjun GPU pool — typically cn-wulanchabu:

bash

# ⚠️ ONLY execute AFTER receiving CONFIRM-CREATE token from the user in a SEPARATE TURN
aliyun paistudio create-resource-group \
  --region cn-wulanchabu \
  --name "${RG_NAME}" \
  --resource-type Lingjun

Hardware purchase NOT implementable via public CLI/SDK. The created ResourceGroup is empty until you purchase MachineGroups via the PAI Console or BSS APIs.

Step 6.4 — Update a ResourceGroup [REQUIRES CONFIRMATION]#

Mandatory steps (strictly ordered): 1. Existence pre-check via get-resource-group (not found → Branch 2, no CLI) → 2. Compute diff (current → new) → 3. --cli-dry-run (MANDATORY) → 4. CONFIRM <RG_NAME> gate → STOP. END THE TURN. Any shortening / skipping = P0 over-reach ( references/compliance-redlines.md R3 + R4). Full gate rules: references/confirmation-gate.md.

⚠️ Parameter-minimization: CLI MUST carry only fields actually changing. Carrying unchanged fields = silent rewrite = over-reach.

Update name only:

bash

aliyun paistudio update-resource-group \
  --region "${REGION_ID}" \
  --resource-group-id "${RESOURCE_GROUP_ID}" \
  --name "${NEW_NAME}"

Update description only:

bash

aliyun paistudio update-resource-group \
  --region "${REGION_ID}" \
  --resource-group-id "${RESOURCE_GROUP_ID}" \
  --description "..."

Changing VPC on an ECS v1.0 ResourceGroup

ECS v1.0 VPC change is a two-step sequence: unbind first, then rebind. Each step requires its own 📋 Resolved Plan block + its own CONFIRM token ( N=1 × M=2 = 2 tokens). For ECS v2.0, VPC changes happen at the Quota level. For Lingjun, see the forbidden-string rule below.

Step 1 — Unbind:

bash

aliyun paistudio update-resource-group \
  --region "${REGION_ID}" \
  --resource-group-id "${RESOURCE_GROUP_ID}" \
  --unbind true

Step 2 — Bind new VPC (PascalCase trio required):

bash

aliyun paistudio update-resource-group \
  --region "${REGION_ID}" \
  --resource-group-id "${RESOURCE_GROUP_ID}" \
  --user-vpc '{"VpcId":"vpc-new","SwitchId":"vsw-new","SecurityGroupId":"sg-new","DefaultRoute":"eth0"}'

🚫 Lingjun VPC refusal — forbidden-string rule: when refusing a Lingjun VPC change, the response MUST NOT contain the literal strings aliyun paistudio update-resource-group or --user-vpc (in any executable form, even as counter-example or dry-run). Refuse in plain natural language and point the user to the Lingjun infrastructure team / account manager. Full rules: references/validation-rules.md §4.

Step 6.5 — List & inspect MachineGroups (read-only)#

bash

aliyun paistudio list-resource-group-machine-groups \
  --region "${REGION_ID}" \
  --resource-group-id "${RESOURCE_GROUP_ID}" \
  --page-number 1 --page-size 20

aliyun paistudio get-resource-group-machine-group \
  --region "${REGION_ID}" \
  --resource-group-id "${RESOURCE_GROUP_ID}" \
  --machine-group-id "${MACHINE_GROUP_ID}"

Additional list filters: --machine-group-ids, --name, --creator-id, --ecs-spec, --payment-type, --status, --order-instance-id, --disk-pl, --payment-duration, --payment-duration-unit, --sort-by, --order.

Step 6.6 — Observe usage / metrics#

⚠️ DEPRECATED — NOT SUPPORTED. If asked for get-resource-group-total, get-resource-group-request, get-user-view-metrics, or get-node-metrics, respond:

"ResourceGroup metrics / request-aggregate APIs have been deprecated and are no longer supported by this skill. Please use the PAI Console or contact your administrator."

Step 6.7 — Delete the ResourceGroup [REQUIRES CONFIRMATION]#

Mandatory steps (strictly ordered): 1. Existence pre-check via get-resource-group (not found → Branch 2, no CLI) → 2. MG-empty pre-check via list-resource-group-machine-groups --page-size 1 ( TotalCount > 0 → Branch 2, direct user to PAI Console) → 3. --cli-dry-run (MANDATORY) → 4. CONFIRM <RG_NAME> gate → STOP. END THE TURN. Ordering is non-negotiable — existence first, MG-count second, dry-run third, CONFIRM last. Any skipping = P0 over-reach ( references/compliance-redlines.md R3 + R4). Full gate rules: references/confirmation-gate.md.

bash

# Pre-check 1 — RG existence (read-only). If empty / NotFound → Branch 2 (validation-rules.md §2 row E2) → STOP.
aliyun paistudio list-resource-groups \
  --region "${REGION_ID}" \
  --resource-group-ids "${RESOURCE_GROUP_ID}"
# OR equivalently:
aliyun paistudio get-resource-group \
  --region "${REGION_ID}" \
  --resource-group-id "${RESOURCE_GROUP_ID}"

# Pre-check 2 — MG count (read-only). Only run AFTER pre-check 1 returned the RG.
aliyun paistudio list-resource-group-machine-groups \
  --region "${REGION_ID}" \
  --resource-group-id "${RESOURCE_GROUP_ID}" \
  --page-size 1
# Expect: TotalCount == 0. Otherwise → Branch 2 (validation-rules.md §2 row E3) → STOP and direct the user
# to release MGs in the PAI Console (the agent CANNOT release MGs on the user's behalf).

# Dry-run (MANDATORY). Only run AFTER both pre-checks pass.
aliyun paistudio delete-resource-group \
  --region "${REGION_ID}" \
  --resource-group-id "${RESOURCE_GROUP_ID}" \
  --cli-dry-run
# Show the dry-run output to the user.

# Pre-checks + dry-run passed → 📋 Resolved Plan (citing both pre-check results as Preconditions verified)
# → verbatim CONFIRM prompt with the real RG name → end the turn → wait for user's next-turn token.

# ONLY execute after receiving CONFIRM token from the user
aliyun paistudio delete-resource-group \
  --region "${REGION_ID}" \
  --resource-group-id "${RESOURCE_GROUP_ID}"

🏁 Exit Checklist + Compliance Red Lines#

[MUST] Before generating the final user-facing reply for any exit path (success / failure / refusal / cancellation / Branch 1 wait / Branch 2), the agent MUST:

1. Confirm every business API call this turn carried --user-agent "AlibabaCloud-Agent-Skills/alibabacloud-pai-resource-group-management/{session-id}" (with a real session id), and that no system/configuration command (e.g., aliyun configure …, aliyun plugin …, aliyun version) was invoked with --user-agent.
2. Pass the §6 Exit Checklist (flow order): branch block → CONFIRM (cross-turn) → CLI with --user-agent. Full 7-point version + recovery procedure: references/exit-checklist.md.
3. Pass the Compliance Red Lines R1-R7 (non-negotiable): MG deletion refused / observability --user-agent present on every business API call / CONFIRM cross-turn / branch block literal / channel pure / Lingjun forbidden-string / parameter minimization. Full table + rationale: references/compliance-redlines.md.

Both checklists are AND, not OR. A missing or malformed --user-agent on any business API call — even on a refusal turn — is a P0 workflow defect.

7. Success Verification#

See references/verification-method.md. Quick check:

• get-resource-group --resource-group-id ${ID} returns the expected Name, ResourceType, and UserVpc (if bound).
• list-resource-group-machine-groups is read-only — used to verify MG inventory, not to mutate it.
• After delete-resource-group, get-resource-group returns a not-found error.

8. Cleanup#

1. User releases all MachineGroups via the PAI Console (this skill cannot and will not delete them).
2. After list-resource-group-machine-groups returns TotalCount=0, run delete-resource-group (subject to the two-step confirmation gate).
