create-pr

# Create Pull Request Comprehensive PR creation with validation. All output goes directly to GitHub PR. ## Quick Start ```bash create-pr create-pr "Add user authentication" ``` > **CC ≥ 2.1.119 multi-host note (M122):** PR creation works against GitHub, GitLab, Bitbucket, and GitHub Enterprise. Detect the target host from the configured remote (`git remote -v`) and branch on the host family for the right CLI: > > | Host family | CLI | > |---|---| > | github / github-enterprise | `gh pr create` (with `GH_HOST=<host>` for GHE) | > | gitlab / gitlab-self | `glab mr create` | > | bitbucket | `bb pr create` | > > Custom enterprise URLs: `prUrlTemplate` setting (see `src/skills/configure/` and `src/skills/chain-patterns/references/pr-from-platform.md`). ## Argument Resolution ```python TITLE = "$ARGUMENTS" # Optional PR title, e.g., "Add user authentication" # If provided, use as PR title. If empty, generate from branch/commits. # $ARGUMENTS[0] is the first token (CC 2.1.59 indexed access) ``` ## Base Branch Resolution Derive the base branch from the remote. Never hardcode `dev` or `main`; repos differ. ```bash BASE=$(git symbolic-ref --short refs/remotes/origin/HEAD 2>/dev/null | sed 's|^origin/||') BASE=${BASE:-main} # ref missing (fresh/shallow clone)? run: git remote set-head origin -a ``` Every `$BASE` below refers to this value. ### Stacked on another open PR When the work depends on an open PR ("a PR that depends on PR #50"), that PR's head branch is the base,...
