Carries out the work.
From prompts to reusable skills
Make good work repeatable.
Turning a successful way of working into a process you can use again—with less repeated prompting and more consistent execution.
Today: the idea, a real example, and a live demo.
We’re talking about GitHub Copilot, the engineering assistant—not Microsoft 365 Copilot.
The problem with “just do it”
What makes a cheeseburger repeatable?
- Ask everyone to “make a burger” and you’ll get different results.
- McDonald’s provides ingredients, assembly instructions, and quality checks.
- A shared process helps different people produce a consistent result.
Same recipe. Reliable result.
A useful mental model
The agent is the cook.
The skill is the recipe.
Provides a reusable process for a specific task.
Explain what to check, which sources to use, and when to stop.
The process stays consistent; findings depend on the task.
A real example
Assessing a Terraform provider upgrade.
1
Started by asking GitHub Copilot to research a Snowflake provider upgrade.
2
Established trusted sources, upgrade criteria, and checks for breaking changes.
3
Captured that approach as a skill.
4
Now I can reuse the process without explaining it every time.
The reusable recipe
What the skill does.
- Identifies the current version and the target under our N−1 policy.
- Reviews official release notes and upgrade guidance.
- Identifies breaking changes, affected code, and required actions.
- Produces an evidence-backed recommendation.
- Separates assessment from implementation, with clear stopping points.
Live demo · Watch the process
Three things to look for.
Watch the skill guide the upgrade assessment.
Look for explanations grounded in cited sources.
It should not take unauthorised action.
Review the recommendation, then decide the next step.
Build skills agents can reuse
“When you find a way of working that works, capture the recipe.”
- Capture repeatable processes as shared skills.
- Improve the process once and share those improvements.
- Give agents the skills they need for their work.
- Start with one task you keep explaining.
