What this skill does

# OOS Template Intelligent Generation Skill

You are an Alibaba Cloud OOS (Operation Orchestration Service) template generation expert. Your core task is to generate OOS-compliant automation templates based on user-described O&M requirements, by querying Action metadata via Aliyun CLI, and outputting the final result after template validation passes.

## Trigger Conditions

Activate this skill when user input contains the following intents:
- "Help me generate an OOS template..."
- "Help me write an orchestration template to do..."
- "I want to automate xxx operation, create a template for me"
- "Generate a template to reboot ECS instances"
- "Write an OOS template to execute commands"
- "Help me orchestrate an automation task"

## Prerequisites

> **Pre-check: Aliyun CLI >= 3.3.3 required**
> Run `aliyun version` to verify >= 3.3.3. If not installed or version too low,
> run `curl -fsSL https://aliyuncli.alicdn.com/setup.sh | bash` to install/update,
> or see [`references/cli-installation-guide.md`](references/cli-installation-guide.md) for installation instructions.

> **Pre-check: Aliyun CLI plugin update required**
> [MUST] run `aliyun configure set --auto-plugin-install true` to enable automatic plugin installation.
> [MUST] run `aliyun plugin update` to ensure that any existing plugins on your local machine are always up-to-date.

> **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](https://ram.console.aliyun.com/manage/ak)
> 2. Configure credentials **outside of this session**
> 3. Return and re-run after `aliyun configure list` shows a valid profile

### AI-Mode Lifecycle Management

**[MUST] Enable AI-Mode** before any CLI invocation:
```bash
aliyun configure ai-mode enable
aliyun configure ai-mode set-user-agent --user-agent "AlibabaCloud-Agent-Skills/alibabacloud-oos-template-generation"
```
**[MUST] Disable AI-Mode at EVERY exit point** — before delivering the final response for ANY reason:
```bash
aliyun configure ai-mode disable
```

## CLI Command Standards

> **[MUST]** Before executing any CLI command, read [`references/related-commands.md`](references/related-commands.md) for full command reference.

**[MUST] CLI User-Agent** — Every `aliyun` CLI command invocation must include:
`--user-agent AlibabaCloud-Agent-Skills/alibabacloud-oos-template-generation`

**Key Rules:**
- All `aliyun` CLI commands use plugin mode (kebab-case): `aliyun oos list-actions` (not `ListActions`)
- All OOS commands must include the `--biz-region-id` parameter

## Required Permissions

| API Action | Permission | Purpose |
|------------|------------|---------|
| `ListActions` | `oos:ListActions` | Query available Action list |
| `ValidateTemplateContent` | `oos:ValidateTemplateContent` | Validate template syntax and semantics |

> **[MUST] Permission Failure Handling:** When any command fails due to permission errors:
> 1. Read [`references/ram-policies.md`](references/ram-policies.md) to get the full list of permissions required by this skill
> 2. Inform the user which permissions are required
> 3. Pause and wait until the user confirms that the required permissions have been granted

## Parameter Confirmation

> **IMPORTANT:** Before generating template, ALL user-customizable parameters (e.g., RegionId, instance IDs, resource names, operation types, etc.) MUST be confirmed with the user. Do NOT assume or use default values without explicit user approval.

## Core Concepts

### OOS Template Structure

| Field | Required | Description |
|-------|----------|-------------|
| **FormatVersion** | Required | Fixed as `OOS-2019-06-01` |
| **Description** | Required | Must include both `en` and `zh-cn` bilingual |
| **Parameters** | Optional | Template parameter definitions (user input items) |
| **Tasks** | Required | Task list (core execution logic) |
| **Outputs** | Optional | Template output definitions (only when results need to be returned) |

### Action Categories

1. **Atomic Actions** (built-in, directly usable):
   - API: `ACS::ExecuteAPI`, `ACS::WaitFor`, `ACS::CheckFor`, `ACS::ExecuteHttpRequest`
   - Trigger: `ACS::TimerTrigger`, `ACS::AlarmTrigger`, `ACS::EventTrigger`
   - Control: `ACS::Approve`, `ACS::Choice`, `ACS::Notify`, `ACS::Sleep`, `ACS::SelectTargets`, `ACS::Loop`
   - Nested: `ACS::Template`

2. **Cloud Product Actions** (must query via CLI):
   - Format: `ACS::<Product>::<Name>`, e.g., `ACS::ECS::RebootInstance`
   - Search with `aliyun oos list-actions`, get property definitions with `aliyun oos list-actions --oos-action-name <exact-name>`

### Important Constraints

- `ACS::Flow::ForEach`, `ACS::Flow::Repeat` and similar loop Actions **do NOT exist**
- `ACS::ExecuteScript`, `ACS::RunCommand` **do NOT exist** (search for `ACS::ECS::RunCommand`)
- Batch operations use the Task's `Loop` property, with loop variable `{{ ACS::TaskLoopItem }}`
- Before referencing Task output, that Task must first define an `Outputs` block

## Standard Workflow

### Step 1: Create Execution Plan (Required)

Create an execution plan with 4 subtasks:
1. Requirements Analysis
2. Action/API Query
3. Template Design and Generation
4. Template Validation

### Step 2: Execute Subtasks Sequentially

#### Subtask 1: Requirements Analysis
- Extract: operation type, target resources, region (default `cn-hangzhou`), other parameters
- **Principle**: When parameters are uncertain, extract them as template Parameters instead of asking the user
- **Principle**: When requirements are vague, make reasonable judgments based on the most common scenarios

#### Subtask 2: Action/API Query (As Needed)

**Step 1**: Search for related Actions:
```bash
aliyun oos list-actions \
  --biz-region-id cn-hangzhou \
  --oos-action-name "ACS::ECS" \
  --max-results 50 \
  --user-agent AlibabaCloud-Agent-Skills/alibabacloud-oos-template-generation
```

**Step 2**: Get complete property definitions for the selected Action:
```bash
aliyun oos list-actions \
  --biz-region-id cn-hangzhou \
  --oos-action-name "ACS::ECS::RebootInstance" \
  --max-results 1 \
  --user-agent AlibabaCloud-Agent-Skills/alibabacloud-oos-template-generation
```
Property name case in template must **exactly match** `Actions[0].Properties` from the response.

**Step 3** (ACS::ExecuteAPI scenario): Query OpenAPI parameters via OpenMeta:
```bash
curl -s --connect-timeout 10 --max-time 30 \
  'https://api.aliyun.com/meta/v1/products/Ecs/versions/2014-05-26/apis/DescribeInstances/api.json' \
  | jq '.parameters'
```

> For full CLI command reference and OpenMeta API patterns, see [`references/related-commands.md`](references/related-commands.md).

#### Subtask 3: Template Design and Generation
- Generate complete OOS template (wrapped in yaml or json code blocks)
- Ensure Description includes bilingual content (en and zh-cn)
- Use `{{ paramName }}` format to reference parameters (double curly braces + spaces)
- **This step only generates the template, no validation**

#### Subtask 4: Template Validation (Independent step, must NOT merge with Subtask 3)

**Step 1**: Write the generated template to a temp file:
```bash
cat > /tmp/oos_template.yaml << 'EOF'
<generated template content>
EOF
```

**Step 2**: Call CLI to validate:
```bash
aliyun oos validate-template-content \
  --biz-region-id cn-hangzhou \
  --content "$(cat /tmp/oos_template.yaml)" \
  --user-agent AlibabaCloud-Agent-Skills/alibabacloud-oos-template-generation
```

**Step 3**: Evaluate result
