AC yuntu-yw-shipping
YunExpress（云途物流）与 Yanwen（燕文物流）的跨境物流查单、报价和制单工具。Use when an ecommerce seller asks to track a YunExpress or Yanwen package, check where a parcel is, look up a waybill/order, shipping channel, warehouse, delivery method, route, price or billable weight, or prepare a shipping order, label, cancellation, or other carrier request for Shopify, Amazon, TikTok Shop, Temu, an independent store, or another ecommerce order. It does not need Shopify login and does not register carrier accounts, automatically dispatch shipments, or write to a carrier without the merchant's credentials, a redacted preview, and explicit approval.

As a process C 60/100 · Has gaps — weak spots: inputs and preconditions, running it twice, progress reporting
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 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.
Narrow allowed-tools and the variable list to the minimum; replace binaries with readable sources or scripts.
How to improve
- For Hermes the description must be one sentence under 60 characters; move the conditions to a "When to Use" section.
- 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 60/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 30Running it twice. 8 mutating operations with no state check
- 50When it triggers. No condition that starts the skill
- 60Tools and files. Uses tools (bash) that frontmatter does not declare
- 60Result and completion. Output format stated, no completion criterion
- 60Consistency. The Hermes dialect needs category and tags
- 85Steps. 25 steps, 1 vague phrases
- 100Failures and branches. 1 branches, has a failure section
- 100Execution cost. Instruction body is 1651 tokens
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.
