manifest-contribute

name: manifest-contribute description: Contribute framework improvements back to the upstream Manifest repo via PR. Use when the user says "contribute back", "open a PR upstream", "send this fix upstream", or wants to share a framework improvement.

Manifest Contribute

Contribute improvements from your application back to the upstream Manifest repository.

When to use: The user says "contribute back", "open a PR upstream", "send this fix upstream", or similar.

Philosophy

The reverse of manifest-update. Update pulls from upstream into your app. Contribute pushes from your app back to upstream. Only framework-level changes are contributed — app-specific code stays local.

The manifest branch is your local read-only copy of the upstream framework. Contributions branch off manifest, cherry-pick framework commits from main, and open a PR against manifest-upstream.

What's Contributable

• Framework improvements (manifest/ files)
• Skill refinements (.pi/skills/)
• Extension improvements or new extensions (extensions/)
• Documentation improvements (AGENTS.md framework sections, SPARK.md)

What's NOT Contributable

• App-specific features (features/)
• App-specific schemas (schemas/)
• App-specific services (services/)
• VISION.md — this is your app's identity
• App-specific config (config/)

Steps

1. Ensure Setup Is Correct

Verify the two-branch model is in place:

# Check manifest-upstream remote
git remote get-url manifest-upstream 2>/dev/null || echo "MISSING"

# Check manifest branch exists
git branch --list manifest | grep -q manifest || echo "MISSING"

If either is missing, set them up first (see the manifest-update skill).

2. Identify Contributable Commits

Find commits on main (or the current feature branch) that touch framework files:

git log main --not manifest -- manifest/ .pi/skills/ extensions/ AGENTS.md SPARK.md --oneline

Read the full commit messages for context:

git log main --not manifest -- manifest/ .pi/skills/ extensions/ AGENTS.md SPARK.md --format="medium"

Present the list to the user. Ask which commits to contribute. Never auto-select everything.

3. Check for Mixed Commits

Some commits may touch both framework and app-specific files. Identify them:

# For each candidate commit, check what files it touches
git show --stat <hash> --name-only

If a commit touches both framework and app files, warn the user: "This commit includes app-specific changes. I'll cherry-pick it and then strip the app-specific parts."

4. Sync Manifest Branch

Make sure manifest is up to date before branching:

git fetch manifest-upstream
git checkout manifest
git merge --ff-only manifest-upstream/main

If fast-forward fails, warn the user — someone committed directly to manifest. This needs manual resolution before continuing.

5. Create a Contribution Branch

git checkout manifest
git checkout -b contribute/<descriptive-name>

Use a descriptive name that reflects what's being contributed (e.g., contribute/router-path-validation, contribute/spark-web-dashboard).

6. Cherry-Pick Selected Commits

git cherry-pick <hash1> <hash2> ...

For mixed commits (framework + app-specific changes):

1. Cherry-pick the commit
2. Remove app-specific file changes:

   git checkout manifest -- <app-specific-files>
   git add -A
   GIT_EDITOR=true git commit --amend
   

3. Verify only framework files remain in the diff

If a cherry-pick conflicts:

1. Read both versions and resolve
2. Stage and continue:

   git add <resolved-file>
   GIT_EDITOR=true git cherry-pick --continue
   

Always use GIT_EDITOR=true to avoid blocking on an interactive editor.

7. Verify the Contribution

Run standard checks on the contribution branch:

bun test
bunx tsc --noEmit

Both must pass. Fix any issues before proceeding.

8. Push and Open PR

Determine whether you can push directly to the upstream repo or need to fork.

Check push access:

# Extract owner/repo from the manifest-upstream remote URL
UPSTREAM_URL=$(git remote get-url manifest-upstream)
UPSTREAM_REPO=$(echo "$UPSTREAM_URL" | sed -E 's#.+github\.com[:/]([^/]+/[^/.]+)(\.git)?$#\1#')

# Check if the authenticated user has push access
gh api "repos/$UPSTREAM_REPO" --jq '.permissions.push' 2>/dev/null

If you have push access (result is true) — push directly:

git push manifest-upstream contribute/<descriptive-name>

Then open the PR:

gh pr create \
  --repo "$UPSTREAM_REPO" \
  --base main \
  --head contribute/<descriptive-name> \
  --title "<type>(<scope>): <summary>" \
  --body "<description>"

If you do NOT have push access (result is false or the check fails) — fork first:

# Fork the upstream repo (idempotent — no-ops if fork already exists)
gh repo fork "$UPSTREAM_REPO" --clone=false

# Get the authenticated user's GitHub username
GH_USER=$(gh api user --jq '.login')

# Add the fork as a remote (skip if already exists)
git remote get-url my-fork 2>/dev/null || git remote add my-fork "https://github.com/$GH_USER/$(basename $UPSTREAM_REPO).git"

# Push to the fork
git push my-fork contribute/<descriptive-name>

Then open the PR from the fork against the upstream repo:

gh pr create \
  --repo "$UPSTREAM_REPO" \
  --base main \
  --head "$GH_USER:contribute/<descriptive-name>" \
  --title "<type>(<scope>): <summary>" \
  --body "<description>"

Note the --head "$GH_USER:contribute/..." syntax — GitHub needs the fork owner prefix when the PR comes from a fork.

PR guidelines (apply to both flows):

• --base main targets the UPSTREAM repo's main branch (the framework). This is NOT your local main branch (your app). On GitHub, main = the framework. Locally, main = your app and manifest = the framework mirror.

The PR title should follow conventional commit format. The body should:

• Explain what was improved and why
• List the files changed and their purpose
• Note any migration steps if the change affects existing users
• Follow the manifest-commit skill conventions for knowledge-transfer writing

9. Return to Your Branch

git checkout main   # or your feature branch

The contribution branch stays around until the PR is merged or closed. Don't delete it prematurely.

Rules

• Only contribute framework-level changes. App code stays local.
• Never auto-select commits. The agent identifies candidates, the user decides.
• Always strip app-specific changes from mixed commits before contributing.
• Always verify before pushing. bun test, bunx tsc --noEmit.
• Always use GIT_EDITOR=true when git commands might open an editor.
• Write a clear PR description. The upstream maintainer needs to understand the improvement without context about your specific app.
• Never modify the manifest branch directly. Contribution branches are created from it, but it remains a read-only mirror.
• Return to your working branch when done — don't leave the repo on the contribution branch.
