qc — quick commit + auto-push

Portable, project-agnostic quick-commit skill. Drop this file at ~/.claude/skills/qc/SKILL.md to make /qc available in every project on the machine.

A project may override this with its own .claude/skills/qc/SKILL.md (project-local takes precedence). Use that for project-specific commit conventions (e.g. required task IDs).

Two invocations

• /qc — commit + push the current branch to its upstream on origin. Default. Use during normal feature-branch work.
• /qc main — switch to main (or master, whichever the repo's default branch is — detect with git symbolic-ref refs/remotes/origin/HEAD), commit, push origin's default branch directly. Solo-speed flow — skips the PR review path. Only use when the user is the only reviewer and the change is ready.

If /qc main is invoked while on a feature branch with uncommitted changes, carry the changes across with git stash --include-untracked → git checkout <default> → git stash pop → resolve any conflicts → continue. If conflicts can't be resolved cleanly, stop and surface to the user; do not throw away work.

Step 0 — Prerequisite: gh installed and authenticated

/qc relies on gh having configured git's credential helper so git push over HTTPS doesn't prompt. Before staging anything, verify:

command -v gh >/dev/null && gh auth status >/dev/null 2>&1

If that exits non-zero, bootstrap before continuing.

Install gh if missing

Detect platform first; pick the matching command:

• Ubuntu / Debian:

  type -p curl >/dev/null || sudo apt install -y curl
  curl -fsSL https://cli.github.com/packages/githubcli-archive-keyring.gpg \
    | sudo dd of=/usr/share/keyrings/githubcli-archive-keyring.gpg
  sudo chmod go+r /usr/share/keyrings/githubcli-archive-keyring.gpg
  echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/githubcli-archive-keyring.gpg] https://cli.github.com/packages stable main" \
    | sudo tee /etc/apt/sources.list.d/github-cli.list > /dev/null
  sudo apt update && sudo apt install -y gh
  

• macOS (Homebrew): brew install gh
• Fedora / RHEL / CentOS Stream: sudo dnf install -y gh
• Arch: sudo pacman -S --noconfirm github-cli
• Alpine: sudo apk add github-cli
• Windows (winget): winget install --id GitHub.cli
• Other / unknown: point the user at https://cli.github.com/ and stop.

sudo will prompt the user — that is expected; do not try to bypass.

Authenticate via browser (one-time)

gh auth login --hostname github.com --git-protocol https --web

This prints a one-time code, opens the user's browser to https://github.com/login/device, and configures git's credential helper on success.

If the host is headless and can't open a browser:

gh auth login --hostname github.com --git-protocol https

Follow the prompts (paste-the-code flow works without a local browser). For SSH protocol instead, swap --git-protocol https → --git-protocol ssh and let gh upload an SSH key for the user.

Verify

gh auth status         # expect "Logged in to github.com account <user>"
git push --dry-run     # confirms credential helper is active for this repo

Re-run the gh auth status check after install/auth before continuing to staging. If any step still fails, stop and surface the failure to the user — do not commit work that can't be pushed.

Step 1 — Inspect the working tree

Run in parallel; read the actual changes before drafting any message:

git status
git diff --stat
git diff --cached
git log -5 --oneline

Look for:

• Files the user may not have meant to commit (.env, *.key, node_modules/, large binaries, __pycache__/).
• Two unrelated concerns mixed in one diff (split into two commits if so — see "Multi-commit batches" below).
• The repo's commit-message conventions, inferred from git log (Conventional Commits? Project-specific tags like [JIRA-123] or [W1.A.0]? Plain prose?). Match the existing style.

Step 2 — Detect project conventions

Before drafting the message, check for project-specific rules in this order (stop at the first hit):

1. CLAUDE.md at repo root — if it specifies a commit format (e.g. Conventional Commits + task ID), follow it exactly.
2. CONTRIBUTING.md — same; many projects encode commit rules here.
3. .gitmessage template or commit.template in .git/config — pre-fill it.
4. Recent commit log — match the dominant style (type(scope): summary if Conventional, JIRA-123: ... if ticket-prefixed, plain imperative one-liner otherwise).

If a project mandates a task ID (e.g. [W1.A.0], JIRA-123, #42), resolve it from:

• An explicit ID the user gave in this turn.
• git log -20 --pretty=%s | grep -oE '<id-pattern>' | head -1 to reuse the active task.
• Project's plan file (BUILD_PLAN.md, ROADMAP.md, .linear/, etc.) cross-referenced with the touched paths.
• If still unresolved, ask before defaulting.

Step 3 — Stage

Prefer named-path staging over git add -A:

git add path/to/file.py path/to/other.md

This avoids sweeping in .env, credentials, __pycache__/, build artifacts, or large binaries the user didn't mean to commit.

git add -A / git add . is acceptable only if:

• The user explicitly said "everything" / "all changes" / "stage all", AND
• git status shows no unexpected files (no .env*, no *secret*, no large unfamiliar additions).

Step 4 — Draft the commit message

One sentence, imperative voice ("add", "fix", "remove" — not "added", "adding"), focused on why the change is being made, not what files changed (the diff already shows that).

Defaults if no project convention is detected:

• Format: <type>(<scope>): <summary>
• type ∈ {feat, fix, test, chore, docs, refactor, perf, style, ci, build, revert}.
• scope is optional but recommended — the module/area touched.
• Summary ≤ 70 chars where possible.
• Body only when the change is non-obvious; skip otherwise.

Verb mapping when picking type:

• New user-visible capability → feat
• Behavior bug fix → fix
• Test added/changed without behavior change → test
• Version pins, tooling, config, dependencies → chore
• Docs only → docs
• No-behavior-change cleanup → refactor
• Performance only, no behavior change → perf

Forbidden in commit messages:

• Co-Authored-By: Claude …, 🤖 Generated with [Claude Code], or any AI-attribution line. Authorship is git committer + signature only.
• Padding like Update files. or Misc changes. — say what changed and why.

State the drafted message to the user in one line before committing, so they can correct it if needed.

Step 5 — Commit

git commit -m "<type>(<scope>): <summary>"

Hard rules — never violate:

• No --no-verify (skipping pre-commit / commit-msg hooks).
• No --no-gpg-sign (skipping GPG signing if the repo requires it).
• No git commit --amend to fold in a fix — that rewrites history. Always make a new commit.
• No --allow-empty unless explicitly requested.

If a pre-commit hook fails: read the failure output, fix the underlying issue (lint, format, type-check, etc.), re-stage the fix, and create a new commit (the hook failure means the prior commit didn't happen — --amend would fold into the previous successful commit, which is wrong). If the hook fails repeatedly on the same issue, stop and root-cause; do not loop.

If the user asks you to bypass hooks, refuse and explain why. Hooks exist because the project's maintainers wanted them; bypassing is a project-policy decision, not a one-off override. Ask the user to either fix the issue or, if they're sure, run the bypass themselves with git commit --no-verify — don't do it on their behalf.

Step 6 — Push

git push -u origin HEAD

If the branch already tracks an upstream, plain git push is fine.

For /qc main:

git push origin <default-branch>

Force-push is not part of /qc. If git push rejects with non-fast-forward, stop and surface to the user. Do not --force or --force-with-lease autonomously — that overwrites someone else's work and is destructive.

Multi-commit batches

If the staged changes are obviously two unrelated concerns (e.g. a feat + an unrelated docs fix), split into two commits with two messages rather than mushing them together. State the split plan before staging the first one.

A reasonable rule of thumb: if you'd write two different type(scope) headers for the same diff, it's two commits.

What /qc does not do

• Open PRs (gh pr create --fill) — that's a separate /ship or gh pr create step.
• Merge PRs (gh pr merge) — same.
• Run tests / lint / type-check manually — pre-commit hooks own that. If hooks aren't installed, run pre-commit install first or surface to the user.
• Force-push, rebase, or rewrite history.
• Skip signing or hooks under any circumstance.
• Edit ~/.gitconfig or set committer identity. If user.name / user.email aren't set, surface to the user — guessing the identity is wrong.

Failure modes — surface, don't silently swallow

• Working tree contains files the user may not want committed (.env, large binaries, secrets) → list them, ask.
• No commit-message convention detectable AND no recent commits to mimic → ask the user for preferred format.
• Required task ID can't be resolved → ask before defaulting.
• Pre-commit hook fails repeatedly on the same issue → stop, root-cause, do not loop.
• git push rejected (non-fast-forward, branch protection, etc.) → show the error verbatim; do not --force.
• gh auth status fails after attempted bootstrap → stop, show the error, ask the user to run gh auth login manually.

Sharing this skill

This file is the entire skill. To share it with a teammate:

1. Send them this SKILL.md.
2. They drop it at ~/.claude/skills/qc/SKILL.md (create the dir if needed).
3. Next Claude Code session, /qc is available globally on their machine.

Or commit a copy at <your-project>/.claude/skills/qc/SKILL.md so anyone working in that project gets it project-locally without installing globally.
