About the project
A better way
to build a skill.
OpenCode Skill Creator brings an evaluation-driven workflow to the skills you create for OpenCode.
From a draft to a decision
Writing a skill is only the beginning. You also need to know when the agent selects it, whether its output helps, and whether a revision improves anything.
This project combines a skill that guides the process with a TypeScript plugin that provides executable tools for validation, trigger evaluation, description improvement, benchmarking, and human review.
One workflow. Two parts.
The skill supplies instructions, supporting references, and a process for creating and improving skills. The plugin supplies the tools the agent calls to carry out that process. Together, they help turn “this seems better” into a comparison you can inspect.
Built on open work
The project adapts Anthropic’s official skill-creator for OpenCode. The original Python tooling was ported to TypeScript and integrated with OpenCode’s plugin architecture.
OpenCode Skill Creator is an independent project maintained by Anton Gulin. References to OpenCode and Anthropic identify the tools and upstream work involved; they do not imply endorsement.
Read it. Use it. Improve it.
