msd-core/gsd-core/workflows/pr-branch.md

Create a clean branch for pull requests by filtering out transient .planning/ commits. The PR branch contains only code changes and structural planning state — reviewers don't see GSD transient artifacts (PLAN.md, SUMMARY.md, CONTEXT.md, RESEARCH.md, etc.) but milestone archives, STATE.md, ROADMAP.md, and PROJECT.md changes are preserved.

Uses git cherry-pick with path filtering to rebuild a clean history.

Parse `$ARGUMENTS` for target branch. If no argument is supplied, detect the default branch via the single resolver (#1146).

Read the sub-repo list from config using the canonical key path — `planning.sub_repos`. A non-zero exit code means the key is absent; treat that as "no sub-repos configured".

SUB_REPOS_JSON=$(gsd_run query config-get planning.sub_repos 2>/dev/null)

  : # Not configured or empty — skip to analyze_commits
fi

Scan each sub-repo for uncommitted changes using node (always available — avoids undeclared jq dependency). Write dirty repo names to a temp file so the list survives across subsequent command executions:

ROOT=$(git rev-parse --show-toplevel)
DIRTY_FILE=$(mktemp)

node -e "
  const repos = JSON.parse(process.argv[1]);
  const { execFileSync } = require('child_process');
  const path = require('path');
  const fs = require('fs');
  const root = process.argv[2];
  // realpath parity with the pr-subrepo seam's validatePath: resolve $ROOT through
  // symlinks once so the containment check below compares real paths, not text.
  let realRoot;
  try { realRoot = fs.realpathSync(root); } catch (_) { realRoot = path.resolve(root); }
  const out = [];
  for (const r of repos) {
    // Reject before any git invocation: this scan runs on raw config values,
    // ahead of the pr-subrepo seam's own validatePath guard. A traversal,
    // embedded-newline, or symlink entry here would run git outside the
    // workspace, or inject a spurious record into the dirty-file output.
    if (typeof r !== 'string' || !/^[A-Za-z0-9._\/-]+$/.test(r)) continue;
    // realpathSync follows symlinks — path.resolve only normalizes '..' textually,
    // so an in-tree symlink pointing outside root would otherwise smuggle git out.
    let resolved;
    try { resolved = fs.realpathSync(path.resolve(realRoot, r)); } catch (_) { continue; }
    if (resolved !== realRoot && !resolved.startsWith(realRoot + path.sep)) continue;
    try {
      const res = execFileSync('git', ['-C', resolved, 'status', '--porcelain'],
                               { encoding: 'utf8', timeout: 10_000 });
      // Exclude untracked-only repos: seam filters ?? lines, so detection must match.
      const tracked = res.split('\n').filter(l => l.length > 0 && !l.startsWith('??'));
      if (tracked.length > 0) out.push(r);
    } catch (_) {}
  }
  fs.writeFileSync(process.argv[3], out.join('\n'));
" "$SUB_REPOS_JSON" "$ROOT" "$DIRTY_FILE"

DIRTY_REPOS=$(cat "$DIRTY_FILE")

If $DIRTY_REPOS is empty, remove the temp file and continue to analyze_commits.

Display dirty repos and prompt the user:

Sub-repos with uncommitted changes:
  backend
  frontend

How should sub-repo changes be handled?
  1. all    — branch, commit (explicit files only), push -u, open companion PR per repo
  2. select — choose which sub-repos to process
  3. skip   — ignore sub-repos, continue with root repo only

If the user chooses skip, remove the temp file and continue to analyze_commits.

For each selected sub-repo $REPO_REL, delegate all git work to the pr-subrepo query seam — it stages explicit changed files (never git add -A), creates the branch, commits, and pushes with --set-upstream. Branch names include the repo slug to avoid colliding with the root PR_BRANCH that create_pr_branch creates later:

# Replace path separators to make the name safe as a branch component
REPO_SAFE="${REPO_REL//\//-}"
SUB_BRANCH="${CURRENT_BRANCH}-${REPO_SAFE}-pr"
COMMIT_MSG="fix(${REPO_REL}): sync uncommitted changes for PR"

RESULT=$(gsd_run query pr-subrepo "$COMMIT_MSG" \
  --repo "$REPO_REL" \
  --branch "$SUB_BRANCH")
SUBREPO_EXIT=$?

If the seam exited non-zero (stage/commit/push failure), report its error and move on to the next selected sub-repo. Do not run the companion-PR step below for this repo — the seam's stderr already explains the failure, and the "branch pushed" path would otherwise contradict it:

if [ "$SUBREPO_EXIT" -ne 0 ]; then
  echo "pr-subrepo failed for $REPO_REL — see error above; skipping companion PR." >&2
fi

Only when $SUBREPO_EXIT is 0, parse the structured result with node and open the companion PR. If remote_slug is null (non-GitHub remote), skip gh pr create and show the push URL instead:

REMOTE_SLUG=$(node -e "
  try { console.log(JSON.parse(process.argv[1]).remote_slug || ''); } catch(_) {}
" "$RESULT")

if [ -n "$REMOTE_SLUG" ]; then
  # Defense-in-depth: $REPO_REL was already validated by the dirty-scan filter and
  # the pr-subrepo seam's validatePath, but these are separate, independent git -C
  # invocations on the same value. Resolve it through symlinks with the SAME realpath
  # containment the seam uses (path.resolve alone would not catch a symlink escape),
  # and run git against the validated absolute path rather than re-concatenating.
  SUB_REPO_DIR=$(node -e "
    const fs = require('fs'), path = require('path');
    try {
      const realRoot = fs.realpathSync(process.argv[1]);
      const resolved = fs.realpathSync(path.resolve(realRoot, process.argv[2]));
      if (resolved !== realRoot && !resolved.startsWith(realRoot + path.sep)) process.exit(1);
      process.stdout.write(resolved);
    } catch (_) { process.exit(1); }
  " "$ROOT" "$REPO_REL" 2>/dev/null)

  if [ -z "$SUB_REPO_DIR" ]; then
    echo "Refusing unsafe sub-repo path: $REPO_REL" >&2
    SUB_TARGET="$TARGET"
  else
    # Resolve base branch: use $TARGET if it exists in sub-repo, else fall back to
    # the sub-repo's own default branch
    if git -C "$SUB_REPO_DIR" ls-remote --exit-code --heads origin "$TARGET" \
         > /dev/null 2>&1; then
      SUB_TARGET="$TARGET"
    else
      SUB_TARGET=$(git -C "$SUB_REPO_DIR" remote show origin 2>/dev/null \
        | awk '/HEAD branch/ {print $NF}')
      SUB_TARGET="${SUB_TARGET:-main}"
    fi
  fi

  gh pr create \
    --repo "$REMOTE_SLUG" \
    --base "$SUB_TARGET" \
    --head "$SUB_BRANCH" \
    --title "$COMMIT_MSG" \
    --body "Companion PR for root repo branch \`$CURRENT_BRANCH\`."
else
  echo "No GitHub remote detected for $REPO_REL — branch pushed, open PR manually."

After processing all selected sub-repos, remove the temp file and continue to analyze_commits for the root repo.

Classify commits:

Structural planning files — always preserved (repository planning state):

• .planning/STATE.md
• .planning/ROADMAP.md
• .planning/MILESTONES.md
• .planning/PROJECT.md
• .planning/REQUIREMENTS.md
• .planning/milestones/**

Transient planning files — excluded from PR branch (reviewer noise):

• .planning/phases/** (PLAN.md, SUMMARY.md, CONTEXT.md, RESEARCH.md, etc.)
• .planning/quick/**
• .planning/research/**
• .planning/threads/**
• .planning/todos/**
• .planning/debug/**
• .planning/seeds/**
• .planning/codebase/**
• .planning/ui-reviews/**

For each commit, check what it touches:

Classify:

• Code commits: Touch at least one non-.planning/ file → INCLUDE
• Structural planning commits: Touch only structural .planning/ files (STATE.md, ROADMAP.md, MILESTONES.md, PROJECT.md, REQUIREMENTS.md, milestones/**) → INCLUDE
• Transient planning commits: Touch only transient .planning/ files (phases/, quick/, research/, etc.) → EXCLUDE
• Mixed commits: Touch code + any planning files → INCLUDE (transient planning changes come along; acceptable in mixed context)

Display analysis:

Commits to include: {N} (code changes + structural planning)
Commits to exclude: {N} (transient planning-only)
Mixed commits: {N} (code + planning — included)
Structural planning commits: {N} (STATE/ROADMAP/milestone updates — included)

```bash PR_BRANCH="${CURRENT_BRANCH}-pr"

Create PR branch from target

git checkout -b "$PR_BRANCH" "$TARGET"

Cherry-pick code commits and structural planning commits (in order):

```bash
for HASH in $CODE_AND_STRUCTURAL_COMMITS; do
  git cherry-pick "$HASH" --no-commit
  # Remove only transient .planning/ subdirectories that came along in mixed commits.
  # DO NOT remove structural files (STATE.md, ROADMAP.md, MILESTONES.md, PROJECT.md,
  # REQUIREMENTS.md, milestones/) — these must survive into the PR branch.
  for dir in phases quick research threads todos debug seeds codebase ui-reviews; do
    git rm -r --cached ".planning/$dir/" 2>/dev/null || true
  done
  git commit -C "$HASH"
done

Return to original branch:

git checkout "$CURRENT_BRANCH"

```bash # Verify no .planning/ files in PR branch PLANNING_FILES=$(git diff --name-only "$TARGET".."$PR_BRANCH" | grep "^\.planning/" | wc -l) TOTAL_FILES=$(git diff --name-only "$TARGET".."$PR_BRANCH" | wc -l) PR_COMMITS=$(git rev-list --count "$TARGET".."$PR_BRANCH") ```

Display results:

✅ PR branch created: {PR_BRANCH}

Original: {AHEAD} commits, {ORIGINAL_FILES} files
PR branch: {PR_COMMITS} commits, {TOTAL_FILES} files
Planning files: {PLANNING_FILES} (should be 0)

Next steps:
  git push origin {PR_BRANCH}
  gh pr create --base {TARGET} --head {PR_BRANCH}

Or use /gsd:ship to create the PR automatically.
