Dependabot PR Rollup

When to use

Use this skill when the user wants to:

• find all open Dependabot PRs in this repo
• reproduce their net effect in one local branch
• validate the result with the repo's standard checks
• optionally commit, push, and open a PR

Workflow

1. Inspect the current checkout state, but do not reuse a dirty worktree.
2. List open Dependabot PRs with gh pr list --state open --author app/dependabot.
3. For each PR, collect the title, base branch, head branch, changed files, and relevant diffs.
4. Compare each PR head against origin/<base> instead of trusting the PR title. Dependabot PRs can already be partially merged, superseded by newer versions, or have no remaining net effect.
5. Create a new worktree and branch from origin/<base>.
6. Reproduce only the remaining dependency changes in the new worktree.
   • Inspect package.json before editing npm dependencies.
   • Run npm ci --ignore-scripts before applying npm updates so dependency commands run from a clean install.
   • Use npm install ... --ignore-scripts for direct npm dependency changes so package-lock.json stays in sync.
   • Preserve whether an npm package is a dependency or devDependency.
   • When updating @biomejs/biome, also update the Biome schema URL version in biome.json to match the installed Biome version.
   • For GitHub Actions updates, apply the net workflow-file changes from the Dependabot PR heads after confirming they still apply cleanly to the selected base.
7. Run npm run all.
8. If requested, commit the changed source, lockfile, workflow files, and generated artifacts, then push and open a PR.

Repo-specific notes

• Use gh for GitHub operations.
• Keep the user's original checkout untouched by working in a separate worktree.
• This repo has Dependabot configured for both npm and github-actions.
• In this repo, npm run all is the safest validation command because it runs build, check, package, and unit tests.
• npm run check may rewrite files with Biome; include those intentional formatting changes.
• If dependency changes affect bundled output, include the regenerated dist/ files from npm run package.

Report back

Always report:

• open Dependabot PRs found
• which PRs required no net changes
• new branch name
• new worktree path
• files changed
• npm run all result
• if applicable, commit SHA and PR URL
