alibabacloud-sysom-diagnosis

alibabacloud-sysom-diagnosis is a skill for Claude Code from alibaba/anolisa. It costs 93 tokens per session (2,553 once invoked), scanned D, original, Apache-2.0.

A troubleshooting guide for Linux server performance and stability problems, including high CPU or memory use, slow disks, and network issues.

In plain words
What is it for?
It helps investigate load, scheduling delays, out-of-memory events, Java heap problems, disk latency, packet loss, network jitter, and generally slow servers.
Why use it?
It directs diagnosis through SysOM, Alibaba Cloud's system-operations tool, before using broader manual checks, while protecting access credentials.

About the project

ANOLISA is a server-side operating layer for AI agent workloads that provides terminal access, token-saving tool-output compression, runtime controls, security, observability, skills, memory, and sandbox management. It is for running and supervising agents from a Linux terminal while retaining an existing shell, agent framework, and sandbox. The catalogue add-ons are components of its agent operating environment and workflows.

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 D, and why

alibabacloud-sysom-diagnosis scanned grade D with 3 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 7d 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.

A mod that escalates privileges can change anything on the machine, not only the project.

How it starts

The opening of the file, as written. The whole thing — 245 lines — stays where its author put it; the contents beside it link to each section on GitHub.

alibabacloud-sysom-diagnosis

Use SysOM CLI and backend envelopes as the diagnosis source of truth. This Skill replaces the older SysOM diagnosis Skill and is the single entry point for SysOM ECS performance and stability diagnosis.

Immediate Route

When the user reports a symptom and has not provided fresh SysOM envelope output, run the matching SysOM command from Domain Routing below before ad hoc Linux inspection or manual probing. Then follow the returned agent.summary, agent.findings[].detail/category, and agent.next_steps[]. Raw Linux commands are bounded fallbacks only when a SysOM command is unavailable, outputs contradict each other, or a required entity remains missing after the focused SysOM command.

Credential Security

Never print, echo, or ask for AccessKey ID or AccessKey Secret values. Remote commands perform their own authentication checks. If a command returns an authentication or permission error, explain the error and point the user to references/ram-policies.md; credential setup must happen outside the conversation.

CLI Setup

Check whether the CLI is available:

command -v sysom-osops

If it is missing, install it:

curl -fsSL --connect-timeout 1000 https://sysom-prd-cn-hangzhou.oss-cn-hangzhou.aliyuncs.com/sysom_prd/skill_cli/install.sh | sudo bash

Then verify only the binary:

command -v sysom-osops

Core Workflow

  1. Classify the user's symptom into one SysOM domain: memory, IO, load/CPU, network, or Java memory.
  2. Run the smallest SysOM command that matches that domain. Prefer a local memory classify for unclear memory symptoms; for other domains, use the matching documented remote action.
  3. Read only the default envelope fields: ok, error, command, and agent.
  4. Build the answer from agent.summary, agent.findings[].detail, agent.findings[].category, and agent.next_steps[]. Keep evidence qualifiers that change interpretation, including currentness, unavailable direct signals, fallback evidence, and remediation preconditions.
  5. If the root cause, key entities, evidence strength, and safe next action are already visible, stop and answer. Run one targeted follow-up only when a required entity is missing or the command explicitly recommends it.

Changes

What this file has done since we first saw it

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.

alibabacloud-sysom-diagnosis is a skill published in the GitHub repository alibaba/anolisa (617 stars, last pushed yesterday), licensed Apache-2.0. It adds 93 tokens to every session and 2,553 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it D with 3 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
