Field notes

Notes from
the skill loop.

Practical guides to creating skills, testing their boundaries, and making the next version better.

Optimization

Better descriptions. Fewer guesses.

Improve a skill description through a measured loop without confusing a better trigger score with better task output.

Evaluation

Test when your skill should trigger

Build positive and negative trigger cases, preserve a holdout set, and learn what the results can tell you.

Getting started

Create your first OpenCode skill

Start with one repeatable task. Turn it into a structured skill, then check it against real examples.
