Compact Dependabot

Merge all open Dependabot dependency bumps into one PR that passes CI.

Steps

1. Fetch the diffs — run the TypeScript tool to download Dependabot PR diffs:

   npx tsx tools/gh-automation/compact-dependabot.ts
   

   This writes dependabot-diffs.patch in the repo root.

2. Study the patch file — read dependabot-diffs.patch to understand what dependencies are being bumped and across which ecosystems (npm, uv/pip, etc.).

3. Reuse the existing branch the user is already on, UNLESS it's on main, in that case, create a new branch from main:

   git fetch origin main
   git checkout -b chore/compact-dependabot origin/main
   

4. Apply the diffs — apply each PR's diff from the patch file. The patch file contains sections separated by comment headers (# PR #<number>: <title>). Apply them with:

   git apply dependabot-diffs.patch
   

   If git apply fails for any section, split the patch by PR section and apply individually. Resolve any conflicts manually.

5. Install updated dependencies — run the appropriate install commands for each ecosystem that changed:

   • npm: npm install
   • uv/pip: uv lock or uv sync

6. Run build:

   npx nx affected --base=origin/main -t build --parallel=3 --configuration=ci --output-style=stream --verbose
   

7. Run lint:

   npx nx affected --base=origin/main -t lint --parallel=3 --configuration=ci --verbose --output-style=stream --verbose
   

8. Fix failures — if build or lint fail, read the errors and fix them. Re-run until green.

9. Commit and push:

   git add -A
   git commit -m "chore: compact dependabot bumps"
   git push origin chore/compact-dependabot
   

10. Open a PR:

    gh pr create --title "chore: compact dependabot bumps" --body "Consolidates open Dependabot PRs into a single change." --base main
    

    Capture the new PR URL from the output.

11. Close the Dependabot PRs — for each Dependabot PR that was included, add a comment linking to the new PR, then close it:

    gh pr comment <number> --body "Superseded by <new-pr-url>"
    gh pr close <number>
    

12. Clean up — delete the patch file:

    rm dependabot-diffs.patch
