jj commit (describe)

Create a commit for the current changes by setting the revision description. In jj there is no staging area; the working copy is the current revision.

Steps

1. Run jj status to see working-copy state and which files changed.
2. Run jj diff to see changes in the current revision (working copy vs parent). Use -r @ to restrict to the current rev if needed.
3. Run jj log -n 5 to see recent commit style.
4. Write a commit message and run jj describe -m "message".

If the user provides a message hint (e.g. in the request), use it when writing the message.

To start a new change before describing, run jj new; then set the description on that revision.

Commit message rules

• Use the imperative mood ("Add", "Fix", "Remove", not "Added", "Fixes", "Removed").
• Be concise: one short sentence, ideally under 50 characters.
• Do NOT use conventional commit prefixes (no feat:, fix:, chore:, etc.).
• Do NOT add any Co-Authored-By or similar trailers.
• Focus on what changed and why, not how.
• If a second line is needed for context, keep it brief.

Examples of good messages

• Prevent discount code from being cleared on edit
• Add integration test for offer code persistence
• Remove unused legacy export helper
• Fix thumbnail missing in upsell insert

When pushing, use jj-bookmark-push; never push without a description.
