force-push-downstream

Force Push Downstream

Force-push a branch and all its downstream branches to their respective remotes. Skips branches whose local and remote tips already match.

Arguments

• starting-branch (optional) — The branch to start from. Defaults to the current branch if not specified.

Examples:

• /force-push-downstream — push current branch + all downstream
• /force-push-downstream candle-service-webui — push from that branch down

Current State

• Branch: !git branch --show-current
• Status: !git status --short

Steps

1. Determine starting branch

If an argument was provided, use it as the starting branch. Otherwise use the current branch.

git branch --show-current

2. Detect downstream chain

Run the detect-chain script (shared with rebase-downstream) to find all downstream branches:

bash .claude/skills/rebase-downstream/detect-chain.sh <starting-branch>

3. Build push list

The push list is: the starting branch itself, followed by every downstream branch in tree order (from detect-chain output).

4. Show plan and confirm

Display the branches that will be pushed:

Force push plan:
  candle-service-background-webcontents

For each branch, check if it is already up-to-date with origin:

If local_sha == remote_sha, mark as (up-to-date, will skip). If the remote branch doesn't exist, mark as (new, will push). Otherwise mark as (diverged, will force-push).

Ask the user to confirm before pushing.

5. Push each branch

For each branch in the push list:

1. Skip if up-to-date: If local SHA matches origin SHA, print skip message and move on.

2. Force push:

   git push --force-with-lease origin <branch>

   Use --force-with-lease for safety — it fails if someone else pushed to the remote since our last fetch, preventing accidental overwrites of others' work.

3. If the remote branch doesn't exist (first push), use:

   git push -u origin <branch>

4. Report result: Print success/failure for each branch.

6. Report summary

After all pushes complete, show a summary:

Force push results:
  ✓ candle-service-background-webcontents (pushed)
  - background-webcontents-timer (skipped, up-to-date)
  ✓ candle-service-webui (pushed)
  ✓ candle-service-model-loading (pushed)
  ✓ brave-history-embeddings (pushed, new)
  ✗ local-ai-internals (failed: ...)

Important

• Always use --force-with-lease instead of --force for safety
• Do NOT push without user confirmation
• Skip branches that are already up-to-date (local == remote SHA)
• If any push fails, report it but continue with remaining branches
• Return to the original branch at the end
