As a process C 51/100 · Has gaps — weak spots: result and completion, when it triggers, inputs and preconditions
What is at stake
Medium-severity findings: the skill is probably honest, but read what alarmed the scanner.
Below is the worst case for this category. The finding here is medium: the guard saw a sign, not a proof.
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
- Say in the description WHEN to use the skill ("use when…", example requests): that is the agent's main cue.
- 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.

cmd-persistenceSKILL.md:208Persistence mechanism (cron / launchd / scheduled task / autorun registry) (quoted — discussed, not commanded)A: 如果需要Cron任务在特定日期和时间执行，你可以在cron表达式中使用`@reboot`来指定任务在系统启动时执行，或者使用`@daily`、`@hourly`等来指定周期性执行。对于特定日期和时间，你可以使用`at`命令来创建一次性任务，或者手动编辑Cron表来添加一个特定的cron表达式。

cmd-persistenceSKILL.md:211Persistence mechanism (cron / launchd / scheduled task / autorun registry) (quoted — discussed, not commanded)A: 如果使用`@reboot`后任务没有执行，可能是因为任务脚本没有正确设置执行权限，或者脚本路径不正确。确保脚本具有执行权限（使用`chmod +x script.sh`），并且脚本路径在系统的PATH环境变量中，或者直接指定完整的脚本路径。

Process rating: all ten parameters 51/100
- 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
- 0Progress reporting. Says nothing while it works
- 20When it triggers. No condition that starts the skill
- 30Running it twice. 6 mutating operations with no state check
- 100Tools and files. Tools declared in frontmatter
- 100Steps. 78 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 2762 tokens
- low 23 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.
