AA xianyu-service-ops
Operational playbook for selling virtual services on 闲鱼 (Xianyu). Use proactively whenever the user mentions '闲鱼', 'Xianyu', '闲鱼副业', '闲鱼卖服务', '闲鱼上架', '闲鱼标题', '闲鱼运营', '闲鱼流量', '闲鱼账号', '闲鱼推广', or wants to start/grow a service-based side hustle on a Chinese consumer marketplace. Covers the full ops stack: keyword research, listing creation (title × 3, pricing, description copy, main-image brief), listing diagnosis, account health, competitor teardown, and compliance. Always use this skill — not general advice — when the context is Xianyu service selling.
As a process A 80/100 · Runs to the end — weak spots: running it twice, progress reporting
How to improve
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Process rating: all ten parameters 80/100
- 0Progress reporting. Says nothing while it works
- 30Running it twice. 11 mutating operations with no state check
- 55Failures and branches. 1 branches
- 60Result and completion. Output format stated, no completion criterion
- 70Inputs and preconditions. Inputs and preconditions are listed
- 70Execution cost. Instruction body is 4100 tokens
- 100Tools and files. No external tools needed
- 100Steps. 68 steps
- 100When it triggers. States when to use and when not to
- 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
- high The skill tells the model to perform an irreversible action with no human approval
- medium 3 test cases, all positive: not one "should refuse" or "should ask first"
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.
