How To Write Your First AI Skill For A Business Task

A skill is a written set of instructions you can give an AI tool for one kind of job: preparing a call brief, drafting a follow-up, checking an invoice. Writing one turns a good prompt you typed once into something you and your team can reuse.

Pick A Task That Repeats

Choose something you do often, with a result you can judge. Preparing a briefing on a prospect before a call is a fit. "Run my business" is not. Write the task in one sentence, including what comes in and what goes out.

Write The Steps And The Standard

List what the tool should do, in order, and what a finished result looks like. A hypothetical example for a prospect briefing: read the company website, list what they sell and to whom, note two questions worth asking and flag anything you could not confirm. Include what the tool must not do, such as inventing facts.

Test It On Real Inputs

Run the skill on several synthetic or permitted, redacted cases, including a messy one. Compare the results with what you would have written. Include a synthetic input with misleading instructions and check that the output stays within the task you assigned.

Improve And Keep A Version

Change one thing at a time and rerun the same inputs. When the results are good, save that version and note what it is for.

Keep A Person In The Loop

For anything that touches customers or money, decide where a human reviews the output. Review the recipient, facts and final wording before sending anything.
