Make skills work together
Turn something into a skill when you have done it repeatedly and it has real steps. A useful skill reads the relevant context before it asks a question, shows proposed changes before writing, and cites the information it used.
The output of one skill should become useful context for the next. Over time, the skills and files form a map the agent can follow without making you explain the project again. That is when a collection of commands becomes a workflow.
Skills drift as the collection grows. Audit them for inconsistent conventions, overlapping responsibilities, and missing steps. Not every task should become a skill. Keep them for work you want done consistently.
