Tair Database AI Assistant

This Skill focuses on Alibaba Cloud Tair (Redis OSS-Compatible) database intelligent O&M, invoking the get-yao-chi-agent API through the aliyun CLI DAS plugin for diagnostics and analysis.

Architecture: Aliyun CLI → DAS Plugin (Signature V3) → get-yao-chi-agent API → Tair Intelligent Diagnostics

Installation

Pre-check: Aliyun CLI >= 3.3.1 required Run aliyun version to verify >= 3.3.1. If not installed or version too low, see references/cli-installation-guide.md for installation instructions. Then [MUST] run aliyun configure set --auto-plugin-install true to enable automatic plugin installation.

bash

# Install aliyun CLI
curl -fsSL https://aliyuncli.alicdn.com/install.sh | bash
aliyun version  # Verify >= 3.3.1

# Enable automatic plugin installation
aliyun configure set --auto-plugin-install true

# Install DAS plugin (get-yao-chi-agent requires plugin for Signature V3 support)
aliyun plugin install --names aliyun-cli-das

# Update all installed plugins to latest version
aliyun plugin update

# Install jq (for JSON response parsing)
# macOS:
brew install jq
# Ubuntu/Debian:
# sudo apt-get install jq

Parameter Confirmation

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.

Parameter	Required/Optional	Description	Default
query	Required	Natural language query content (including region, instance info)	-
--session-id	Optional	Session ID for multi-turn conversation	-
--profile	Optional	aliyun CLI profile name	default

Authentication

This Skill relies on the aliyun CLI default credential chain for authentication — no explicit AK/SK handling is required in the Skill workflow.

The CLI automatically resolves credentials in the following priority order:

1. --profile flag on the command line
2. ALIBABA_CLOUD_PROFILE environment variable
3. ALIBABA_CLOUD_ACCESS_KEY_ID / ALIBABA_CLOUD_ACCESS_KEY_SECRET environment variables
4. Configuration file ~/.aliyun/config.json (current profile)
5. ECS Instance RAM Role (if running on ECS)

For credential setup and configuration modes (OAuth, AK, StsToken, RamRoleArn, EcsRamRole, etc.), see references/cli-installation-guide.md.

RAM Policy

See references/ram-policies.md

Core Workflow

All intelligent O&M operations are invoked through scripts/call_yaochi_agent.sh, which wraps aliyun das get-yao-chi-agent (DAS plugin kebab-case command, supports Signature V3) with streaming response parsing.

Before executing any CLI command, AI-Mode must be enabled; after workflow ends, it must be disabled:

bash

# [MUST] Enable AI-Mode before executing CLI commands
aliyun configure ai-mode enable
aliyun configure ai-mode set-user-agent --user-agent "AlibabaCloud-Agent-Skills/alibabacloud-tair-ai-assistant"

bash

# Instance management
bash $SKILL_DIR/scripts/call_yaochi_agent.sh "List Tair instances in Hangzhou region"
bash $SKILL_DIR/scripts/call_yaochi_agent.sh "Show detailed configuration of instance r-xxx"

# Performance diagnostics
bash $SKILL_DIR/scripts/call_yaochi_agent.sh "Analyze instance r-xxx performance in the last hour"
bash $SKILL_DIR/scripts/call_yaochi_agent.sh "Show slow commands of instance r-xxx"

# Memory analysis
bash $SKILL_DIR/scripts/call_yaochi_agent.sh "Analyze memory usage of instance r-xxx"
bash $SKILL_DIR/scripts/call_yaochi_agent.sh "Detect big keys in instance r-xxx"

# Hotspot key detection
bash $SKILL_DIR/scripts/call_yaochi_agent.sh "Find hotspot keys in instance r-xxx"

# Parameter tuning
bash $SKILL_DIR/scripts/call_yaochi_agent.sh "How to tune maxmemory-policy for instance r-xxx"
bash $SKILL_DIR/scripts/call_yaochi_agent.sh "Explain hz parameter"

# Connection and session
bash $SKILL_DIR/scripts/call_yaochi_agent.sh "How to troubleshoot high connection count in instance r-xxx"

# Backup recovery
bash $SKILL_DIR/scripts/call_yaochi_agent.sh "Show backup status of instance r-xxx"

# Multi-turn conversation (use session ID from previous response)
bash $SKILL_DIR/scripts/call_yaochi_agent.sh "Continue analysis" --session-id "<session-id>"

# Specify profile
bash $SKILL_DIR/scripts/call_yaochi_agent.sh "List instances" --profile myprofile

# Read from stdin
echo "List instances" | bash $SKILL_DIR/scripts/call_yaochi_agent.sh -

bash

# [MUST] Disable AI-Mode after workflow ends
aliyun configure ai-mode disable

Cleanup

This Skill focuses on query and diagnostics capabilities, does not create any resources, no cleanup required.

The following operations are NOT within the scope of this Skill:

• Create/delete Tair instances
• Change instance specifications
• Purchase/renew instances

API and Command Tables

See references/related-apis.md

Best Practices

1. Instance ID Format: Tair/Redis instance IDs typically start with r-, include the full instance ID in queries
2. Region Specification: Explicitly specify region in natural language queries (e.g., "Hangzhou region", "Beijing region") to improve query accuracy
3. Multi-turn Conversation: Use --session-id for complex diagnostic scenarios to maintain context continuity
4. Concurrency Limit: Maximum 2 concurrent sessions per account, avoid initiating multiple parallel calls
5. High-risk Operations: For operations involving parameter changes, master-replica switchover, always remind users to verify in test environment first
6. Throttling Handling: If encountering Throttling.UserConcurrentLimit error, wait for previous query to complete and retry
7. Credential Security: Use aliyun configure to manage credentials, never hardcode AK/SK in scripts
