BF Shipping Optimizer
Reduce per-shipment costs and improve delivery speed by analyzing carrier rates, package dimensions, zone distribution, and fulfillment method mix — with concrete rate negotiation targets and carrier selection rules for your order profile.

How to improve
- Say in the description WHEN to use the skill ("use when…", example requests): that is the agent's main cue.
- The text references files that are not there: add them or drop the references.
- 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.

- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 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
- 40Consistency. Frontmatter name (Shipping Optimizer) differs from the folder (shipping-optimizer)
- 60Failures and branches. 2 branches
- 100Steps. 68 steps
- 100Execution cost. Instruction body is 2603 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.
