DWS cluster I/O overload root cause diagnosis skill, based on KooCLI v3.2.0+ and DWS Autopilot MCP Server. Automatically collects I/O metrics, analyzes root causes (customer-side / system-side) via three-stage decision tree, and outputs a standardized diagnosis report. Applicable to DWS cluster I/O usage too high, I/O alarms, disk I/O load anomaly scenarios. Trigger words: "I/O高", "I/O告警", "I/O诊断", "I/O过载", "IO高", "IO告警", "IO诊断", "IO过载", "磁盘IO负载异常", "util打满", "await高", "high I/O", "I/O alarm", "I/O diagnosis"

What is at stake

Medium-severity findings: the skill is probably honest, but read what alarmed the scanner.

Dangerous commands medium severity

Below is the worst case for this category. The finding here is medium: the guard saw a sign, not a proof.

If you install

The skill contains commands that delete files, rewrite disks or execute code fetched from the network. The agent may run them without asking if it believes the instructions require it.

For the author

Replace destructive commands with safe equivalents that ask for confirmation, scope them to one folder, and stop piping curl into a shell: pin a version and a checksum.

How to improve

  1. The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
For the model run — optional
  • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
  • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Against the Agent Skills spec

  • warning body-long SKILL.md body ≈ 9836 tokens (recommended < 5000); move details to references/
  • note frontmatter-key unknown frontmatter key "trigger"
  • note frontmatter-key unknown frontmatter key "input_schema"
  • note frontmatter-key unknown frontmatter key "output_schema"

Process rating: all ten parameters 74/100

  • 0Progress reporting. Says nothing while it works
  • 30Running it twice. 4 mutating operations with no state check
  • 40Execution cost. Instruction body is 9836 tokens: crowds the task out of the window
  • 50When it triggers. No condition that starts the skill
  • 60Steps. 134 steps, 6 vague phrases
  • 60Result and completion. Output format stated, no completion criterion
  • 100Tools and files. Tools declared in frontmatter
  • 100Inputs and preconditions. Inputs and preconditions are listed
  • 100Failures and branches. 6 branches, has a failure section
  • 100Consistency. Name and required fields are in place
  • low 10 top-level sections: this looks like several domains in one skill

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.

Quality signals

  • +4Description does not say when NOT to use the skill (false activations)
  • +1No license
  • +2Single-language instructions
  • +5Description quotes 6 example trigger phrases
  • +3Description length 514: enough signal without eating the budget
  • +4Structure: 32 headings
  • +3Step-by-step instructions: 134 items

Quality base 70; lint remarks subtract, signals add up to 100. Result: 83.

External checks

ClawHub: suspicious
This DWS diagnostic skill is mostly read-only and purpose-aligned, but it needs Review because it expands beyond its declared tool list, handles cloud credentials in risky ways, and saves potentially sensitive reports locally.
