create-commit

Create one or more jj commits from the working copy. If the user asked to split changes or if the diff spans clearly unrelated areas, use the split workflow. Otherwise, default to a single commit. > Prefer using a subagent as the context is unnecessary in main thread. Can return final commit message back from the subagent. ## Important Context - Uses **Jujutsu (jj)**, not git - All changes in the working copy are automatically tracked ## Steps ### 1. Understand Current State Run these in parallel: ```bash jj status # See all changes jj diff # See detailed changes jj log -r 'ancestors(@, 3)' # Recent commits for style reference ``` ### 2. Assess Changes Check if changes should be a single commit or split: - **Single commit**: changes are few, logically one unit (feature, bug fix, refactor) - **Suggest split**: changes span multiple distinct areas (e.g. unrelated features, tests + code changes + config). Present the proposed groups to the user and let them decide. - **User requested split**: skip suggestion, go straight to split workflow ### 3a. Simple Commit ```bash jj describe -m "$(cat <<'EOF' brief description (1-2 sentences) Optional body if reasoning isn't obvious from the diff EOF )" jj new ``` Guidelines: - Keep first line under 72 chars - Do NOT commit secrets - Do NOT push unless requested - Do NOT add `Co-Authored-By` lines unless the user asks ### 3b. Split into Logical Commits 1. Group changed files into logical sets — by feature/purpose, layer (code vs tests vs config), or file relationships 2. Present the proposed grouping to the user and wait for confirmation 3. For N groups, do N-1 splits: ```bash jj split -m "$(cat <<'EOF' <commit message for this group> EOF )" <file1> <file2> ... ``` 4. After all splits, describe the remaining commit: ```bash jj describe -m "$(cat <<'EOF' <commit message for last group> EOF )" ``` 5. Create new working revision: ```bash jj new ``` ### 4. Verify ```bash jj log -r 'ancestors(@, 3)' ``` ## Branch/Bookmark Naming - Veeam repos: prefix with `meain/` (e.g. `meain/earn-prod-adx-sku-downsize`) - Other repos: follow project conventions ## Notes - If changes within a single file need splitting, mention this limitation and suggest `jj split -i` done manually - Never use interactive split (`-i` flag) in scripts - Prefer meaningful groups over many tiny commits
