dev: Command for Claude Code

Squash & PR

Squash all commits on the current branch into a single conventional commit and open a pull request.

Arguments: $ARGUMENTS — optional issue number/identifier (e.g. 42, ORG-123)

Steps

1. Detect base branch — run git branch -a and determine whether the repo uses main or master as the default branch. Store as <base>.

2. Detect git platform — run git remote get-url origin and classify:

   • Contains github.com → GitHub (use gh CLI)
   • Contains gitlab.com or a self-hosted GitLab pattern → GitLab (use glab CLI)
   • Contains bitbucket.org → Bitbucket (limited CLI — provide manual URL)

3. Resolve issue number — if $ARGUMENTS is provided, use it as the issue identifier. Otherwise, extract from the current branch name using common patterns:

   • fix/123-description → 123
   • feature/ORG-123-description → ORG-123
   • issue-42 → 42
   • If no issue number can be extracted, proceed without one.

4. Fetch issue context (if an issue number was resolved):

   • GitHub: gh issue view <number>
   • GitLab: glab issue view <number>
   • Bitbucket: skip (use branch name and commit context instead)

   Use the issue title and description to inform the commit message.

5. Analyze branch commits — run git log --oneline <base>..HEAD to understand the full scope of work done on this branch.

6. Analyze the diff — run git diff <base>...HEAD to understand exactly what changed.

7. Generate conventional commit message using all context gathered:

   type(scope): description (#issue)
   
   body — what changed and why, summarizing the full branch work
   
   Closes #issue
   

   Follow the same rules as /commit: imperative, lowercase description, no period. Scope is the primary module/feature affected.

8. Squash commits — run:

   git reset --soft $(git merge-base <base> HEAD)
   

   Then commit all staged changes with the generated message using git commit -m "<message>".
