Sibling skills (local only)

Sibling CloudBase skills ship beside this skill. Use local relative paths such as ../auth-tool-cloudbase/SKILL.md.

If a referenced sibling skill file is missing from this environment, ask the user to install the full CloudBase plugin (or the missing skill). Do not HTTP-fetch remote skill or protocol markdown into the agent context.

Activation Contract

Use this first when

• The user wants to check the health or status of CloudBase resources (cloud functions, CloudRun, databases, storage, etc.).
• The user reports errors, failures, or abnormal behavior and wants a quick diagnosis.
• The user asks for an "inspection", "health check", "巡检", "诊断", or "troubleshooting" of their CloudBase environment.
• The user wants to review recent error logs across services.
• The user asks 告警解读 questions: whether a CPU 告警 is normal, what 峰值 QPS was, or whether throttle/error metrics look healthy.
• The symptom matches a v3 fault playbook: 429 / 限频, 云函数 404, ACCESS_TOKEN_INVALID, or 调用量为 0.

Read before writing code if

• The inspection reveals code-level issues in cloud functions or CloudRun services — then read the relevant implementation skill before suggesting fixes.
• The user wants to fix a problem found during inspection rather than just diagnose it.

Then also read

• Alarm interpretation baselines -> references/alarm-interpretation.md
• Fault playbooks (429 / 404 / token / zero calls) -> references/fault-playbooks.md
• Cloud function issues -> ../cloud-functions/SKILL.md
• CloudRun issues -> ../cloudrun-development/SKILL.md
• Database issues -> ../postgresql-development-cloudbase/SKILL.md for CloudBase PG / PostgreSQL, ../relational-database-mcp-cloudbase/SKILL.md for MySQL, or ../cloudbase-document-database-web-sdk/SKILL.md for NoSQL
• Auth readiness (token failures) -> ../auth-tool-cloudbase/SKILL.md
• Platform overview -> ../cloudbase-platform/SKILL.md

Do NOT use for

• Deploying new resources or writing application code. This skill is read-only and diagnostic.
• Replacing proper monitoring/alerting infrastructure. It provides point-in-time inspection, not continuous monitoring.
• Directly fixing problems — it diagnoses and recommends; actual fixes should use the appropriate implementation skill.
• Fetching metrics by guessing cloud API Actions. Never use callCloudApi for monitor curves — always use queryEnv(action="metrics").

Common mistakes / gotchas

• Running a full inspection without first confirming the environment is bound (auth tool must show logged-in and env-bound state).
• Ignoring CLS log service status — if CLS is not enabled, queryLogs will fail; always check first with queryLogs(action="checkLogService").
• Searching logs without a time range — this can return excessive or irrelevant results. Always scope searches to a relevant time window.
• Treating a single error log as the root cause without correlating across resources. A function error may stem from a database or config issue.
• Answering "峰值 QPS" / "CPU 告警是否正常" from screenshots or memory instead of queryEnv(action="metrics").
• Calling callCloudApi with invented GetMonitorData / DescribeCurveData parameters — the metrics branch already wraps Manager SDK.

Minimal checklist

• Environment is bound and accessible (queryEnv(action="info"))
• Metrics pulled with queryEnv(action="metrics") when the question involves QPS / CPU / throttle / invocation volume
• CLS log service is enabled (queryLogs(action="checkLogService")) when log diagnosis is needed
• Matching fault playbook selected when symptoms match 429 / function 404 / ACCESS_TOKEN_INVALID / 调用量为 0
• Time range is specified for any log or metrics searches
• Findings are summarized with severity levels, 告警解读, and actionable recommendations

How to use this skill (for a coding agent)

Ops Inspector v3 additions

v3 adds two mandatory capabilities on top of log/resource inspection:

1. 告警解读 — pull metrics, compare to baselines in references/alarm-interpretation.md, answer CPU-alert / peak-QPS style questions in plain language.
2. 故障剧本 — when symptoms match, follow references/fault-playbooks.md instead of ad-hoc tool fishing.

Inspection Modes

Mode	When to use	Scope
Full inspection	User asks for a general health check / 巡检 / 全面检查	All resource types + core metrics
Targeted inspection	User reports a specific error or asks about a specific resource	One resource type or playbook
Alarm interpretation	User asks CPU 告警是否正常 / 峰值 QPS / 是否限流	Metrics-first, then logs
Fault playbook	429 / function 404 / ACCESS_TOKEN_INVALID / 调用量为 0	Playbook steps only

Full Inspection Workflow

Follow these steps in order for a comprehensive environment health check:

Step 1 — Environment Check

queryEnv(action="info")

Confirm the environment is accessible. Record the envId for console link generation.

Step 2 — Metrics snapshot (v3)

queryEnv(action="metrics", envId="<EnvId>", metricName="GatewayTraceEnvQPS")
queryEnv(action="metrics", envId="<EnvId>", metricName="FunctionInvocation")
queryEnv(action="metrics", envId="<EnvId>", metricName="MysqlCpuUsageRate")

Use returned Summary.max / avg / allZero / peakTimestamp. Add FunctionError, FunctionThrottle, or CloudRun Tke* metrics when those resources exist. Read references/alarm-interpretation.md before concluding.

Step 3 — Log Service Status

queryLogs(action="checkLogService")

If CLS is not enabled, note this as a warning — log-based diagnosis will be unavailable. Recommend enabling CLS in the console: https://tcb.cloud.tencent.com/dev?envId=${envId}#/devops/log

Step 4 — Cloud Functions Inspection

queryFunctions(action="listFunctions")

For each function, check:

• Status: Is the function in an active/deployed state?
• Recent errors: queryFunctions(action="listFunctionLogs", functionName="<name>", startTime="<recent>")
• Common issues:
  • Timeout errors (execution exceeded limit)
  • Memory limit exceeded
  • Runtime errors (unhandled exceptions)
  • Cold start frequency
  • Zero invocations while traffic is expected → Playbook 4

Step 5 — CloudRun Services Inspection

queryCloudRun(action="list")

For each service, check:

• Status: Is the service running?
• Detail: queryCloudRun(action="detail", detailServerName="<name>")
• Metrics: queryEnv(action="metrics", metricName="TkeQPSService", resourceID="<serviceName>") (resourceID required)
• Common issues:
  • Service not running (scaled to zero or crashed)
  • Image pull failures
  • OOMKilled events
  • Health check failures

Step 6 — Error Log Aggregation (if CLS is enabled)

queryLogs(action="searchLogs", queryString="ERROR", service="tcb", startTime="<24h-ago>", limit=50)
queryLogs(action="searchLogs", queryString="ERROR", service="tcbr", startTime="<24h-ago>", limit=50)

Look for patterns:

• Repeated error messages (same error many times)
• Cascading failures (errors in multiple services around the same time)
• Timeout / 429 / 404 / ACCESS_TOKEN_INVALID patterns → jump to the matching playbook

Step 7 — Summary Report

Generate a structured report:

# CloudBase Resource Inspection Report

**Environment**: ${envId}
**Inspection Time**: ${timestamp}

## Overall Health: ✅ Healthy / ⚠️ Warnings Found / ❌ Issues Found

## 告警解读
| 问题 | 指标 | 窗口峰值 | 基线 | 结论 |

Targeted Inspection Workflow

When the user specifies a resource type or a specific resource:

1. Cloud function errors: queryFunctions(action="listFunctionLogs", functionName="<name>") then queryLogs(action="searchLogs", queryString="* AND functionName:<name> AND level:ERROR", ...)
2. CloudRun errors: queryCloudRun(action="detail", detailServerName="<name>") then queryLogs(action="searchLogs", queryString="ERROR", service="tcbr", ...)
   • If logs show DB / Redis connection failures (ECONNREFUSED, timeout, "could not connect"): check whether VpcConf is set and matches the database VPC. See cloudrun-development/references/vpc-and-database.md.
3. Database issues: Check queryPgDatabase(action="context"|"metadata"|"objects") for CloudBase PG, queryMysqlDatabase for MySQL, or readNoSqlDatabaseStructure for NoSQL depending on type; for CPU/disk alerts also pull MysqlCpuUsageRate / MysqlStorageUsage metrics
4. General error search: queryLogs(action="searchLogs", queryString="<error-keyword>", ...)
5. Alarm / QPS questions: follow references/alarm-interpretation.md
6. 429 / function 404 / ACCESS_TOKEN_INVALID / 调用量为 0: follow references/fault-playbooks.md

AIOps Methodology

This skill follows AIOps principles for intelligent inspection:

1. Data Collection: Gather metrics (queryEnv metrics), logs, and resource states via MCP tools — never via ad-hoc callCloudApi
2. Pattern Recognition: Identify recurring errors, anomaly patterns, and correlations across services
3. Baseline Comparison: Compare metric Summary values to skill baselines (告警解读)
4. Root Cause Hypothesis: Based on error patterns + metrics, suggest likely root causes
5. Actionable Recommendations: Provide specific, prioritized remediation steps with links to relevant skills and console pages

Severity Levels

Level	Icon	Meaning
Critical	❌	Service is down or data is at risk; requires immediate action
Warning	⚠️	Errors detected but service is still partially functional; investigate soon
Info	ℹ️	No errors found; informational status only
Healthy	✅	Resource is operating normally

Preferred Tool Map

Operation	MCP Tool Call
Check environment	queryEnv(action="info")
Query metrics (QPS/CPU/invocations)	queryEnv(action="metrics", envId, metricName="...")
Check CLS status	queryLogs(action="checkLogService")
List cloud functions	queryFunctions(action="listFunctions")
Get function detail	queryFunctions(action="getFunctionDetail", functionName="<name>")
Get function logs	queryFunctions(action="listFunctionLogs", functionName="<name>", startTime="<time>", endTime="<time>")
Get function log detail	queryFunctions(action="getFunctionLogDetail", requestId="<id>")
List CloudRun services	queryCloudRun(action="list")
Get CloudRun detail	queryCloudRun(action="detail", detailServerName="<name>")
Search CLS logs	queryLogs(action="searchLogs", queryString="<query>", service="tcb|tcbr", startTime="<time>", endTime="<time>")
Check NoSQL structure	readNoSqlDatabaseStructure(action="listCollections")
Check PostgreSQL context	queryPgDatabase(action="context")
Check PostgreSQL metadata	queryPgDatabase(action="metadata", limit=20)
Check MySQL status	queryMysqlDatabase(action="getContext")
Auth provider readiness	queryAppAuth / auth-tool skill (for ACCESS_TOKEN_INVALID)

Common CLS Query Patterns

Scenario	queryString
All errors	ERROR
Function timeout	timeout OR 超时
Function OOM	OOM OR out of memory OR 内存超限
CloudRun crash	crash OR OOMKilled OR Error
Specific function errors	functionName:<name> AND level:ERROR
5xx HTTP errors	statusCode:>499
429 / throttle	429 OR throttle OR 限流 OR FREQUENCY
Function 404	404 OR FUNCTION_NOT_FOUND
Token invalid	ACCESS_TOKEN_INVALID OR token invalid
Cold start issues	coldStart OR 冷启动

Time Range Guidance

• Quick check: Last 1 hour (startTime = 1 hour ago)
• Standard inspection: Last 24 hours
• Trend analysis: Last 7 days
• Specific incident: Narrow to the reported time window

Always use ISO-like YYYY-MM-DD HH:mm:ss for metrics startTime/endTime, e.g., "2026-08-17 00:00:00".
