BF app-cache-migration
将 Windows 系统上任意开发工具（如 VSCode、Yarn、npm、pip、Gradle、Docker 等）的缓存、插件、数据目录迁移到指定目录（如 E/D 盘），通过 NTFS Junction 实现对应用完全透明的重定向。当用户请求"迁移应用的缓存到 X 盘"、"将 XX 的数据目录移到 D/E 盘"、"释放 C 盘空间"、"清理并迁移 XX 缓存"或类似意图时触发。 (user)
As a process F 34/100 · Will not run — weak spots: steps, result and completion, when it triggers
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") - note
frontmatter-keyunknown frontmatter key "agent_created"
Process rating: all ten parameters 34/100
- 0Steps. Prose only: no discrete steps
- 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
- 40Consistency. Frontmatter name (app-cache-migration) differs from the folder (cache-migration)
- 100Tools and files. No external tools needed
- 100Execution cost. Instruction body is 2501 tokens
- 100Running it twice. No mutating operations
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.

ClawHub: suspicious
This cache-migration skill needs Review because it can delete and permanently redirect local application folders and edit VSCode launch files without strong safeguards.
