How to compile selected harnesses

Compile the current project into dist/ for the harnesses you choose. skillprism build only writes that directory. If you have never compiled a skill, follow Create a skill and compile it first.

Run the command from the project directory, or from any directory under it.

To compile every harness named in that file:

skillprism build

To compile only some of them, pass -H with a comma-separated list, or repeat the flag:

skillprism build -H claude,opencode

Each id must be a built-in harness or a harness file under harnesses/. The flag replaces the list in skillprism.yaml for that run.

To see a unified diff and write nothing:

skillprism build -H claude --diff

If a file under dist/ already exists, build asks before replacing it. Flags are in the CLI reference. Where files land is in Directories and state. To copy a skill into a live directory, use How to install, update, and remove a skill.
