BD env-change-guard
在修改环境变量或系统变量时，记录改了什么，并用电脑小白能听懂的话解释这次改动会带来什么影响。也适用于用户表示某个程序、命令、环境或系统功能出了问题，但又说不清具体原因时，优先从相关 log、报错信息或可见线索入手；如果日志相关，就先有限排查 log 内容，再继续正常排查其他可能原因，并用电脑小白能听懂的话解释。常用于 PATH、JAVA_HOME、Python、Node、ADB、Android SDK、OpenClaw 等环境相关场景。

How to improve
- Say in the description WHEN to use the skill ("use when…", example requests): that is the agent's main cue.
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
description-no-whendescription does not say WHEN to use the skill (no "use when")
Process rating: all ten parameters 48/100
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Failures and branches. Linear process with no failure handling
- 20When it triggers. No condition that starts the skill
- 60Tools and files. Uses tools (python) that frontmatter does not declare
- 100Steps. 38 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 244 tokens
- 100Running it twice. No mutating operations
- 100Progress reporting. Reports progress
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
- +5Description has no quoted example phrases that should trigger the skill
- +4Description does not say when NOT to use the skill (false activations)
- +3Output format is not stated: the model decides each time
- +4No input/output examples
- +1No license
- +2Single-language instructions
- +3Description length 220: enough signal without eating the budget
- +4Structure: 8 headings
- +3Step-by-step instructions: 38 items
Quality base 70; lint remarks subtract, signals add up to 100. Result: 68.
