AA parcelcli
Track parcels locally with parcelcli for Evri, Royal Mail, UPS, FedEx, and DHL. Use when the user asks to track a package, detect a carrier, check delivery status, watch a parcel, or summarize courier tracking without sending tracking data to third-party aggregators.
As a process A 90/100 · Runs to the end — weak spots: running it twice, progress reporting

How to improve
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.

Process rating: all ten parameters 90/100
- 0Progress reporting. Says nothing while it works
- 30Running it twice. 2 mutating operations with no state check
- 60Result and completion. Output format stated, no completion criterion
- 100Tools and files. No external tools needed
- 100Steps. 8 steps
- 100When it triggers. States when to use and when not to
- 100Inputs and preconditions. Inputs and preconditions are listed
- 100Failures and branches. 4 branches, has a failure section
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 671 tokens
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
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.

External checks
ClawHub: clean
This skill is a coherent parcel-tracking helper that uses an external local CLI and stores watch state only when the user asks.
