CF china-mirror-resolver

Self-healing China mirror source resolver. Automatically discovers, validates, and configures domestic mirror sources for pip/npm/yarn/pnpm/conda/Docker/Go/ Rust/Maven/Gradle/Homebrew/apt/yum/GitHub/HuggingFace when downloads are slow or timing out in mainland China. Trigger keywords: "换源", "镜像源", "下载慢", "超时", "timeout", "mirror", "registry", "proxy", "connection refused", "SSL error", "443", "ETIMEDOUT", "CondaHTTPError", "pip install failed".

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.

Broad scope 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 asks for more than the task needs: broad tool access, credential environment variables, binaries. Every extra permission widens the damage from a mistake or a compromise.

For the author

Narrow allowed-tools and the variable list to the minimum; replace binaries with readable sources or scripts.

How to improve

  1. The text references files that are not there: add them or drop the references.
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 missing-ref reference to a missing file: scripts/validate.ps1
  • note frontmatter-key unknown frontmatter key "homepage"

Process rating: all ten parameters 50/100

Will not run. References files that are not bundled: scripts/validate.ps1
  • 0Tools and files. 1 referenced file(s) missing: scripts/validate.ps1
  • 0Inputs and preconditions. Does not say what the process needs to start
  • 0Progress reporting. Says nothing while it works
  • 30Running it twice. 9 mutating operations with no state check
  • 40Result and completion. Does not say what the result is
  • 50When it triggers. No condition that starts the skill
  • 70Execution cost. Instruction body is 4248 tokens
  • 100Steps. 20 steps
  • 100Failures and branches. 1 branches, has a failure section
  • 100Consistency. Name and required fields are in place
  • medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
  • low 10 top-level sections: this looks like several domains in one skill
  • low The response is described with custom markup (50 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.

Quality signals

  • +4Description does not say when NOT to use the skill (false activations)
  • +3Output format is not stated: the model decides each time
  • -4Absolute local paths (C:\Users, /home/…): not portable
  • +2Single-language instructions

Quality base 70; lint remarks subtract, signals add up to 100. Result: 86.
