alibabacloud-ecs-linux-os-troubleshooting

alibabacloud-ecs-linux-os-troubleshooting is a skill for Claude Code, Codex from aliyun/alibabacloud-ecs-troubleshoot-skills. It costs 84 tokens per session (3,464 once invoked), scanned A, original, Apache-2.0.

A troubleshooting guide and toolkit for diagnosing Linux operating systems running on Alibaba Cloud ECS, a cloud virtual-machine service. It focuses on a specified instance and uses the Alibaba Cloud command-line tool to inspect it remotely.

In plain words
What is it for?
Use it when an Alibaba Cloud ECS Linux instance will not start or accept connections, has disk or network issues, behaves slowly, crashes, hangs, drifts in time, or may be running hidden mining processes.
Why use it?
It narrows diagnosis to the affected machine and its operating system, helping investigate login, network, storage, startup, performance, crash, clock, and hidden-process problems.

SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.
    Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.
  • medium Excessive Agency · line 113
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

alibabacloud-ecs-linux-os-troubleshooting scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

ECS Linux Troubleshooting

This skill applies only to Linux GuestOS on Alibaba Cloud ECS and diagnoses abnormal issues on the Alibaba Cloud ECS Linux instance specified by the user (the target instance). The agent may run on the target instance or another machine, and uses the aliyun CLI to remotely diagnose and collect data from the target ECS instance.

When to Use This Skill

  • The troubleshooting target specified by the user is an Alibaba Cloud ECS Linux instance.
  • The user's description involves abnormal issues such as mismatches between startup/running status and OS state, remote login failures, network connectivity failures, disk expansion/mount issues, performance anomalies, crashes or hangs, clock drift, or configurations not taking effect.
  • Not applicable: non-Alibaba Cloud ECS, non-Linux GuestOS, other clouds or physical machines; purely control-plane, billing, or API-side issues with no GuestOS involvement.

Principles and Requirements

  1. Troubleshooting target = the Alibaba Cloud ECS Linux instance specified by the user: all checks and conclusions must target that one machine. Commands and paths in references/ are written for the in-instance environment.
  2. Use the aliyun CLI for remote diagnosis and data collection: except for the steps in references/utils/guestos-pe-prep.md, all other steps may only use the subcommands listed in references/aliyun-cli-cheatsheet.md. Do not call subcommands that are not listed there.
  3. Clarify the problem before investigating: strictly follow the troubleshooting workflow. First narrow the user's description to a phenomenon domain, then follow the corresponding troubleshooting document. Do not skip phases or reorder them, and do not draw a conclusion or stop the workflow early when the evidence does not uniquely point to a single root cause.
  4. Prefer the commands described in the references/<slug>.md troubleshooting document. Do not blindly guess commands on your own.
  5. External reference material: when a troubleshooting document contains a URL, such as an Alibaba Cloud help page, you must fetch the content of that link and use it as the basis for the investigation. Do not judge based only on the link title or on prior knowledge.
  6. Multiple-instance scenarios: troubleshoot each ECS instance separately. Do not use results from instance A to draw conclusions about instance B.
  7. Least-privilege permissions: before running this skill, ensure the caller has only the required RAM actions for the selected workflow. Use references/ram-policies.md as the permission source of truth.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
