Use when user questions involve PolarDB, cluster IDs starting with pc-, kernel parameters, primary-standby switchover, IMCI columnar storage, etc. --- # PolarDB Database AI Assistant This Skill focuses on **Alibaba Cloud PolarDB MySQL/PostgreSQL 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` → PolarDB Intelligent Diagnostics ### Supported Capabilities | Capability | Description | |------------|-------------| | PolarDB Primary-Standby Switchover Analysis | Failover cause investigation, switchover log analysis, unexpected Failover diagnostics | | PolarDB Kernel Parameter Change Assessment | Impact assessment before parameter modification, change risk analysis | | PolarDB Kernel Parameter Explanation | Parameter meaning explanation, configuration suggestions, performance impact analysis | | PolarDB Kernel Parameter Explanation (IMCI) | IMCI columnar engine related parameter explanation | | PolarDB Kernel Version Proxy Diagnostics | Proxy layer troubleshooting, version compatibility diagnostics | | PolarDB Kernel Version Instance Diagnostics | Instance layer version issue diagnostics, upgrade suggestions | | Instance Query Filter | PolarDB instance search and filtering | | Proxy Performance Monitoring | Proxy layer performance metrics analysis, connection routing diagnostics | | Serverless Configuration | Serverless instance parameters and elastic scaling configuration | | SQL Optimization Analysis | Slow SQL analysis, index suggestions, execution plan interpretation | | Expiring Instance Query | Subscription instance expiration reminder | | Backup Status Check | Backup completion, retention policy, recovery point in time | | Storage Usage Diagnostics | Storage consumption analysis, growth trends, space optimization suggestions | | Security Configuration Audit | Whitelist, SSL, security policy audit | | Instance Status Check | Instance health status, running status verification | | Log Diagnostics | Error log analysis, slow log troubleshooting | | Auto-Increment ID Overflow Detection | Auto-increment ID exhaustion risk detection, primary key overflow warning | | Connection and Session Analysis | Connection count monitoring, session issue troubleshooting, connection pool optimization | | Cluster Performance Monitoring | QPS/TPS/connections/throughput and other core metrics analysis | | High Availability and Disaster Recovery | HA configuration assessment, disaster recovery architecture diagnostics | ## Installation > **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 update, > or see [references/cli-installation-guide.md](references/cli-installation-guide.md) for installation instructions. > Then **[MUST]** run `aliyun configure set --auto-plugin-install true` to enable automatic plugin installation. > Then **[MUST]** run `aliyun plugin update` to ensure that any existing plugins on your local machine are always up-to-date. **[MUST] CLI User-Agent** — Every `aliyun` CLI command invocation must include: `--user-agent AlibabaCloud-Agent-Skills/alibabacloud-polardb-ai-assistant` **[MUST] Enable AI-Mode** — AI-mode is required for Agent Skill execution. Run the following commands before any CLI invocation: ```bash aliyun configure ai-mode enable aliyun configure ai-mode set-user-agent --user-agent [REDACTED_SECRET] ``` **[MUST] Disable AI-Mode at EVERY exit point** — Before delivering the final response for ANY reason, always disable AI-mode first. This applies to ALL exit paths: workflow success, workflow failure, error/exception, user cancellation, session end, or any other scenario where no further CLI commands will be executed. AI-mode is only used for Agent Skill invocation scenarios and MUST NOT remain enabled after the skill stops running. ```bash aliyun configure ai-mode disable ``` ```bash # Install aliyun CLI curl -fsSL https://aliyuncli.alicdn.com/setup.sh | bash aliyun version # Verify >= 3.3.3 # 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 # 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, cluster info) | - | | `--session-id` | Optional | Session ID for multi-turn conversation | - | | `--profile` | Optional | aliyun CLI profile name | default | ## Authentication Credentials use existing aliyun CLI configuration, **no additional AK/SK setup required**: ```bash # Recommended: OAuth mode aliyun configure --mode OAuth # Or: AK mode aliyun configure set \ --mode AK \ --access-key-id <your-access-key-id> \ --access-key-secret <your-access-key-secret> \ --region cn-hangzhou # Cross-account access: RamRoleArn mode aliyun configure set \ --mode RamRoleArn \ --access-key-id <your-access-key-id> \ --access-key-secret <your-access-key-secret> \ --ram-role-arn acs:ram::<account-id>:role/<role-name> \ --role-session-name yaochi-agent-session \ --region cn-hangzhou ``` ## RAM Policy See [references/ram-policies.md](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. ```bash # Cluster management bash $SKILL_DIR/scripts/call_yaochi_agent.sh "List PolarDB clusters in Hangzhou region" bash $SKILL_DIR/scripts/call_yaochi_agent.sh "Show detailed configuration of cluster pc-xxx" # Performance diagnostics bash $SKILL_DIR/scripts/call_yaochi_agent.sh "Analyze cluster pc-xxx performance in the last hour" bash $SKILL_DIR/scripts/call_yaochi_agent.sh "Show slow SQL of cluster pc-xxx" # Parameter tuning bash $SKILL_DIR/scripts/call_yaochi_agent.sh "How to tune innodb_buffer_pool_size for cluster pc-xxx" bash $SKILL_DIR/scripts/call_yaochi_agent.sh "Explain loose_polar_log_bin parameter" # Primary-standby switchover diagnostics bash $SKILL_DIR/scripts/call_yaochi_agent.sh "Analyze recent primary-standby switchover cause for cluster pc-xxx" # Connection and session bash $SKILL_DIR/scripts/call_yaochi_agent.sh "How to troubleshoot high connection count in cluster pc-xxx" # Backup recovery bash $SKILL_DIR/scripts/call_yaochi_agent.sh "Show backup status of cluster pc-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 clusters" --profile myprofile # Read from stdin echo "List clusters" | bash $SKILL_DIR/scripts/call_yaochi_agent.sh - ``` ### Example Questions | Scenario | Example Question | |----------|------------------| | Cluster Management | List nodes of cluster pc-xxx | | Performance Diagnostics | How to troubleshoot high CPU usage in cluster pc-xxx | | Slow SQL Analysis | Show slow SQL in cluster pc-xxx in the last hour | | Parameter Tuning | What does loose_polar_log_bin parameter mean | | IMCI Parameters | How to configure IMCI related parameters for cluster pc-xxx | | Primary-Standby | How to handle high primary-standby delay in cluster pc-xxx | | Backup Recovery | When was the latest backup of cluster pc-xxx | | Storage Optimization | What to do if storage usage of cluster pc-xxx grows too fast | | Connection Troubleshooting | Cluster pc-xxx connections are full | | Security Audit | Check security configuration of cluster pc-xxx | ## Success Verification See [references/verification-method.md](references/verification-method.md) ## 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 PolarDB clusters - Change instance specifications - Purchase/renew instances ## API and Command Tables See [references/related-apis.md](references/related-apis.md) ## Best Practices 1. **Cluster ID Format**: PolarDB cluster IDs typically start with `pc-`, include the full cluster 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, primary-standby 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 ## Reference Links | Reference | Description | |-----------|-------------| | [references/cli-installation-guide.md](references/cli-installation-guide.md) | Aliyun CLI installation and configuration guide | | [references/related-apis.md](references/related-apis.md) | Related API and CLI command list | | [references/ram-policies.md](references/ram-policies.md) | RAM permission policy list | | [references/verification-method.md](references/verification-method.md) | Success verification methods | | [references/acceptance-criteria.md](references/acceptance-criteria.md) | Acceptance criteria |
