A Git-branchless workflow helper that synchronizes a stack of related commits with the main branch. Git-branchless is a Git workflow for building and managing several dependent commits, often used for stacked pull requests.

Use it to sync a commit stack with local or remote main, pull the latest changes, handle merge conflicts, and clean up after a merge.

It reduces the manual work of fetching updates, rebasing dependent commits, and cleaning up after a pull request is merged.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00021	$0.00972
Opus 5.5	$0.00008	$0.00389
Sonnet 5.5	$0.00004	$0.00194
Haiku 4.5	$0.00002	$0.00097

Security

Grade A, and why

bl-sync scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Examples

# Sync with local main
/bl-sync

# Fetch and sync (most common)
/bl-sync --pull

# After your PR was merged on GitHub
/bl-sync --after-merge

Execution

This command delegates to the bl-sync-expert agent:

Task(subagent_type="git-workflow:bl-sync-expert",
     prompt="Execute sync: <options>")

Execution Instructions

- Check working directory is clean
Show Current State
- Run git sl to display the stack
- Show divergence from main if any
Execute Sync
- For basic sync: git sync
- For pull + sync: git sync --pull
- For after-merge: git pull origin main then git move
Handle Conflicts
- Show conflicting files
- Guide through resolution
- Continue with git rebase --continue
Remind About PRs
- If branches exist, suggest git submit to update PRs
Confirm Result
- Show final state with git sl
