Enhance Sync Pr

Enhance sync PR (Tokens Studio → spectrum-design-data)

When this applies

• PR opened by mrcjhicks from tokens-sync/patch-spectrum2-from-main (or similar sync branch).
• Body links to github.com/adobe/spectrum-tokens-studio-data/actions/runs/….
• CI red after sync (validation, snapshot, component props, wireframe, etc.).
• Changeset missing; title still feat: updates from spectrum-tokens-studio-data or duplicated feat: Feat:.

Repo and tools

• Monorepo root: workspace root (spectrum-design-data).
• Changeset generator: tools/token-changeset-generator — fetches source PR motivation, runs tdiff, infers semver bump.
• Automation: .github/workflows/enhance-sync-pr.yml and .github/actions/extract-source-pr-info.

1. Resolve source PR

From the design-data PR body, take the spectrum-tokens-studio-data Actions run URL or the Tokens Studio PR link.

gh pr view <N> --repo adobe/spectrum-design-data --json body,title,headRefName,url

If only the run URL exists, resolve merged PR from that run (same logic as extract-source-pr-info).

Record:

• Source PR URL (e.g. https://github.com/adobe/spectrum-tokens-studio-data/pull/297)
• Source author (user.login from that PR) for attribution

gh api repos/adobe/spectrum-tokens-studio-data/pulls/<num> --jq '{title, author: .user.login, body}'

2. Diagnose CI (suggest fixes; user approves edits)

Check out the PR branch with full history (fetch-depth: 0) so tdiff can compare to main.

Run in order:

moon run tokens:validateDesignData
moon run tokens:verifyDesignDataSnapshot
cd packages/tokens && pnpm ava

Or full graph: moon ci (same as GitHub Actions).

Failure map (what to suggest)

Re-run targeted tasks after each fix until green.

3. PR title and body

• Title: One conventional prefix. Strip a leading feat: / Feat: (and similar) from the source title, then use feat: <clean title> (avoid feat: Feat: …).
• Body template:

## Token updates from Spectrum Tokens Studio Data

**Original implementer:** @<github-login>

**Source PR:** [#<n> <title>](<url>)

**Automated sync via:** [GitHub Actions run](<run-url>)

### Source description

<paste or summarize source PR body / motivation>

---

<keep existing automated footer if present>

Use gh pr edit <N> --repo adobe/spectrum-design-data --title "..." --body-file body.md.

4. Changeset + git attribution

Generate changeset (requires GITHUB_TOKEN for API rate limits):

cd tools/token-changeset-generator && pnpm install --frozen-lockfile
GITHUB_TOKEN=... node src/cli.js generate \
  --tokens-studio-pr 'https://github.com/adobe/spectrum-tokens-studio-data/pull/<num>' \
  --spectrum-tokens-pr 'https://github.com/adobe/spectrum-design-data/pull/<N>' \
  --source-author '<login>'

Bump type is inferred from diff (e.g. deletions → major, additions → minor).

Commit using the source implementer’s git identity so changelog "Thanks @…" matches design work:

git config user.email '<email>'
git config user.name '<display name>'
git add .changeset/*.md
git commit -m "chore: add changeset for <short summary>" -m "Co-authored-by: <name> <email>"

If the commit author is already the implementer, Co-authored-by is optional but harmless.

5. Verify

moon run tokens:validateDesignData
moon run tokens:verifyDesignDataSnapshot
cd packages/tokens && pnpm ava
pnpm changeset-lint check .changeset/*.md

Push the branch; confirm CI and changeset-bot on the PR.

Reference: prior manual PRs

Well-formed examples: merged sync PRs with token-changeset-generator-style changesets and enriched bodies (e.g. #615, #593). Early PRs used hand-written "Design motivation" + "Token diff" in the changeset body — the generator now standardizes that shape.
