CB alibabacloud-ebs-disk-snapshot-management
This skill should be used when the user asks about Alibaba Cloud ECS disk snapshots, including creating snapshots, listing snapshots, deleting snapshots, rolling back disks, configuring auto snapshot policies, calculating snapshot costs, managing snapshot lifecycle, or using snapshot consistency groups for crash-consistent backup of an entire instance. Triggers on phrases like "create ECS snapshot", "query snapshot list", "delete snapshot", "rollback disk", "auto snapshot policy", "snapshot cost", "snapshot consistency group", "crash-consistent backup", "consistency backup", or Chinese equivalents "创建快照", "查询快照列表", "删除快照", "回滚云盘", "自动快照策略", "快照费用", "快照一致性组", "一致性备份", "整机备份", "崩溃一致性备份", "整机崩溃一致性备份", and broader ECS disk maintenance intents such as "帮我处理一下 ECS 实例", "给云盘做备份", "ECS 云盘运维".

As a process B 70/100 · Nearly there — weak spots: result and completion, execution cost, running it twice
What is at stake
The skill contains fragments that, in the wrong hands, cost money or data. Below: what the installer risks and what the author should do.
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.
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
- Address the high-severity findings: each costs 18 safety points. If one is a false positive, add the rule id to guard.allow in spec.yaml.
- The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
- 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.

Process rating: all ten parameters 70/100
- 10Execution cost. Instruction body is 17504 tokens: crowds the task out of the window
- 30Running it twice. 147 mutating operations with no state check
- 40Result and completion. Does not say what the result is
- 60Tools and files. Uses tools (bash, web) that frontmatter does not declare
- 70When it triggers. States when to use, but not when not to
- 85Steps. 142 steps, 3 vague phrases
- 100Inputs and preconditions. Inputs and preconditions are listed
- 100Failures and branches. 18 branches, has a failure section
- 100Consistency. Name and required fields are in place
- 100Progress reporting. Reports progress
- low 19 top-level sections: this looks like several domains in one skill
- low The response is described with custom markup (4 tags): a typed call is more reliable
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.
