by RediSearch
Split a jj (Jujutsu) changeset into smaller, focused changesets. Use when asked to break up a large changeset, split commits, reorganize changes across revisions, or create stacked PRs from a single changeset. Covers safe duplication-based workflows, file-path and hunk-level splitting without interactive commands.
build
by RediSearch
Compile the project to verify changes build successfully. Use this to verify your changes build properly together with the complete project and dependencies, and make sure to use it before running end to end tests.
refactor
by FradSer
This skill should be used when the user asks to refactor specific files or directories, simplify recently changed code, clean up dead code in a limited scope, or invokes /refactor with paths or semantic queries.
