Aliyun SLS CLI

Command-line interface for managing Alibaba Cloud Simple Log Service (SLS) resources including projects, logstores, Logtail configs, machine groups, and other non-query operations.

Prerequisites

Before starting, verify that aliyun-cli and sls plugin are installed:

aliyun version
aliyun sls version

Expected output: aliyun-cli-sls 0.1.0 (5e6288421) or similar

Installation (if not installed)

If the check fails, follow references/cli-installation-guide.md to install aliyun-cli, then install the sls plugin:

aliyun plugin install --names sls

Update Plugins

aliyun plugin update sls

Check Alibaba Cloud credentials configured

Run aliyun configure list to check if credentials configured. If no valid profile is shown, STOP here and ask the user to run aliyun configure outside of this session.

Security rules:

• NEVER read, echo, or print AK/SK values
• NEVER ask the user to paste AK/SK into the conversation
• ONLY use aliyun configure list to check credential status

Observability

When this skill is loaded, generate one random session ID for the session: a 32-character lowercase hex string.

Every aliyun command that calls a cloud API must include this User-Agent flag:

--user-agent "AlibabaCloud-Agent-Skills/alibabacloud-sls-cli-guidance/{session-id}"

Local utility commands do not call cloud APIs and should not include --user-agent, including aliyun version, aliyun configure ..., aliyun plugin ..., and aliyun help ....

Example:

aliyun sls list-project \
  --offset 0 --size 50 \
  --user-agent "AlibabaCloud-Agent-Skills/alibabacloud-sls-cli-guidance/a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6"

Log Query and Analysis

Use the alibabacloud-sls-query skill for all log query and analysis tasks. It covers SLS query & analysis syntax (index search, SQL, SPL), scenario examples, troubleshooting, and end-to-end query workflows — it is the required skill for querying SLS logs.

Use alibabacloud-sls-query when the user asks to:

• query logs, analyze logs, or troubleshoot query results
• write, explain, optimize, or execute SLS index search, SQL, SQL scan, or SPL
• translate natural language into an SLS query, SQL, or SPL statement
• debug get-logs-v2, query syntax, index/statistics prerequisites

If the skill is already available, use it directly. If not, see alibabacloud-sls-query-installation to install and load it.

Common Operations

For project, logstore, index management, Logtail config, machine group, put-logs, and other non-query SLS operations, stay in this skill and refer to the reference docs below. Read the corresponding reference file first before executing any of them.

CLI Usage

Discover APIs

aliyun help sls
aliyun help sls <apiName>

Validate command syntax (dry-run)

Add --cli-dry-run to validate parameters without executing:

aliyun sls list-project --offset 0 --size 50 --cli-dry-run

Output format

All commands return JSON by default. Use --cli-query with JMESPath expressions to filter output:

aliyun sls list-project --cli-query "projects[*].name"

Global parameters

• --cli-dry-run: Validate command without execution
• --cli-query <jmespath>: Filter output with JMESPath
• --region <region>: Override region
• --help: Show command help

Troubleshooting

When a command fails or returns unexpected results, read references/troubleshooting.md for the full checklist, including:

• CLI and plugin version issues
• Credentials and region configuration
• Common errors (ProjectNotExist, Unauthorized, InvalidParameter, etc.)
• Cross-region project discovery (for ProjectNotExist)

Rules

1. Do not use deprecated APIs — use the current replacement so behavior stays supported and predictable.

   Deprecated	Use instead
   get-logs	get-logs-v2

2. Obtain explicit user approval before any delete — delete operations are irreversible.

3. Use --cli-dry-run first for destructive operations (delete, update).

4. Update APIs require full parameters — first call the corresponding Get API to retrieve current parameters, then include all meaningful parameters in the update call (including unchanged ones). Omitting parameters may reset them to defaults.

5. If a command fails: follow references/troubleshooting.md.

6. Use skill alibabacloud-sls-query for log query and analysis.
