## Standalone Install Note

If this environment only installed the current skill, start from the CloudBase main entry and use the published `cloudbase/references/...` paths for sibling skills.

- CloudBase main entry: `https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/SKILL.md`
- Current skill raw source: `https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/references/ops-inspector/SKILL.md`

Keep local `references/...` paths for files that ship with the current skill directory. When this file points to a sibling skill such as `cloud-functions` or `cloudrun-development`, use the standalone fallback URL shown next to that reference.

## 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.

### 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

- Cloud function issues -> `../cloud-functions/SKILL.md` (standalone fallback: `https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/references/cloud-functions/SKILL.md`)
- CloudRun issues -> `../cloudrun-development/SKILL.md` (standalone fallback: `https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/references/cloudrun-development/SKILL.md`)
- Database issues -> `../relational-database-tool/SKILL.md` (standalone fallback: `https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/references/relational-database-tool/SKILL.md`) or `../no-sql-web-sdk/SKILL.md` (standalone fallback: `https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/references/no-sql-web-sdk/SKILL.md`)
- Platform overview -> `../cloudbase-platform/SKILL.md` (standalone fallback: `https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/references/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.

### 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.

### Minimal checklist

- [ ] Environment is bound and accessible (`envQuery(action="info")`)
- [ ] CLS log service is enabled (`queryLogs(action="checkLogService")`)
- [ ] All target resources are listed before diving into details
- [ ] Time range is specified for any log searches
- [ ] Findings are summarized with severity levels and actionable recommendations

## How to use this skill (for a coding agent)

### Inspection Modes

The skill supports two modes based on user intent:

| Mode | When to use | Scope |
|------|-------------|-------|
| **Full inspection** | User asks for a general health check / 巡检 / 全面检查 | All resource types in the environment |
| **Targeted inspection** | User reports a specific error or asks about a specific resource | One resource type or a specific resource |

### Full Inspection Workflow

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

**Step 1 — Environment Check**

```
envQuery(action="info")
```

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

**Step 2 — 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 3 — 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

**Step 4 — CloudRun Services Inspection**

```
queryCloudRun(action="list")
```

For each service, check:
- **Status**: Is the service running?
- **Detail**: `queryCloudRun(action="detail", detailServerName="<name>")`
- **Common issues**:
  - Service not running (scaled to zero or crashed)
  - Image pull failures
  - OOMKilled events
  - Health check failures

**Step 5 — 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)
- Timeo
