Pr To Main

breaking-brake/pr-to-main

Create a PR to the main branch for feature/fix changes in this pnpm + Changesets monorepo. Use when the user says "PRを作成", "mainにPR", or wants to submit changes for review. Always run this in the monorepo-aware way — identify the affected package(s) and make sure a changeset exists, because the release pipeline is Changesets-driven.

PR to Main Branch

Create a PR for a feature/fix branch targeting main in the cc-wf-studio monorepo.

This is a pnpm monorepo with four packages (packages/core, packages/mcp, packages/cli, packages/vscode) and versioning is driven by Changesets, not commit messages. Two monorepo facts shape this workflow:

  • A release-worthy change must ship with a .changeset/*.md file in the same PR. Without it, the change merges but never gets released — and pending changesets later block promotion to production.
  • Knowing *which package(s)* changed drives the changeset target, the PR scope, and the commit scope (e.g. fix(vscode):).

So the job here is not just "open a PR" — it's "open a PR that the release pipeline can actually act on."

Workflow

  • Gather context (run in parallel):
  • git status (no -uall)
  • git diff (staged + unstaged) and git diff origin/main...HEAD for the full branch delta
  • git log origin/main..HEAD --oneline for every commit on the branch
  • Check whether the branch tracks a remote and needs pushing
  • ls .changeset/*.md to see whether a changeset already exists
  • Identify scope and type:
  • Affected package(s): map changed paths to packages — packages/core@cc-wf-studio/core, packages/mcp@cc-wf-studio/mcp, packages/cli@cc-wf-studio/cli, packages/vscodecc-wf-studio (the VSCode extension). Changes outside packages/ (root config, .github/, docs) usually need no release.
  • Type: read the commit prefix, allowing an optional scope — fix: / fix(vscode): → fix, feat: / feat(core): → feat, improvement: → improvement. Review all commits on the branch, not just the latest.
  • Ensure a changeset exists (the monorepo-critical step):
  • If a .changeset/*.md already covers this change, confirm it names the right package(s) and bump level, and move on.
  • If the change should be released and no changeset exists, create one with pnpm changeset — select the affected package(s) from step 2, choose patch/minor/major, and write a one-line summary (this becomes the CHANGELOG entry). Note: bumping @cc-wf-studio/core auto-bumps its dependents, so you don't author separate changesets for cli/mcp.
  • If the change genuinely needs no release (CI-only, tooling, docs), record that intent explicitly with pnpm changeset add --empty so the pipeline isn't left guessing.
  • Why this matters: releases are cut later by manually opening the Release PR (which consumes the accumulated changesets) and merging it — that merge auto-publishes. A PR that lands without the right changeset silently never gets released. (See docs/release-flow.md for the release side — releasing is a human-only action, not something to self-trigger.)
  • Verify the build is green before opening the PR:
  • Run pnpm check && pnpm build from the repo root (Biome + type-checks, then full compilation). Reviewers and CI expect a clean tree, and catching breakage now is cheaper than after review.
  • Select the PR template based on type (from step 2):
  • fix:assets/fix-template.md
  • feat:assets/feat-template.md
  • improvement:assets/improvement-template.md
  • Create the PR:
  • Push the branch with git push -u if it has no upstream.
  • Open it with gh pr create --base main, filling the chosen template.

PR Format

  • Language: always write the PR title and body in English (repo rule).
  • Titlemain merges via squash, so the PR title *becomes* the squash commit subject. It must therefore follow the commit convention: <type>(<scope>): <description>.
  • <type>: matches the change type from step 2 — fix / feat / improvement / docs / refactor / chore / ci.
  • <scope>: the affected package/area from step 2 — vscode, cli, mcp, core (use the directory name, not the npm name). List several as (cli, mcp). Omit the scope for repo-wide changes (root config, .github/, top-level docs), e.g. ci: guard against pending changesets.
  • <description>: imperative mood, no trailing period, concise (aim ≤50 chars per the commit guideline; GitHub appends a (#NN) suffix, with a leading space, on squash — so don't pad it).
  • Examples (from this repo's history): fix(vscode): parse Changesets-format CHANGELOG, feat(cli): ccwf install-skills subcommand, docs: add root README for the monorepo.
  • Body: in the Changes section, write real monorepo paths (packages/vscode/src/..., packages/core/...), not generic placeholders.
  • Mention the changeset in the body so reviewers can see the intended release effect — e.g. "Adds a patch changeset for cc-wf-studio" or "No release needed (empty changeset)".

Templates

  • fix: assets/fix-template.md — Problem/Solution with Current vs Expected behavior.
  • feat: assets/feat-template.md — Summary/Motivation/Changes.
  • improvement: assets/improvement-template.md — Before/After comparison.

How to use it

Copy the folder

Take breaking-brake/pr-to-main from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
