A setup command for git-branchless, a Git workflow tool for working with stacks of commits. It prepares the repository and can use a chosen branch as the main branch.

Use it to initialize git-branchless in an existing repository and choose its main branch. You can also control whether Git leaves the current branch.

It removes the manual setup steps and checks needed before using git-branchless. It also leaves the repository in the expected state for stack-based work.

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	$0.00016	$0.01049
Opus 5.5	$0.00006	$0.00420
Sonnet 5.5	$0.00003	$0.00210
Haiku 4.5	$0.00002	$0.00105

Security

Grade C, and why

bl-init scanned grade C with 1 finding 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

/bl-init - Git-Branchless Repository Initialization

Category: Git Workflow

Initialize git-branchless in the current repository, using the current branch as the main branch by default. Automatically detaches HEAD so you're ready to start stacking commits.

Usage

/bl-init [options]

Options

Option	Description
(none)	Initialize using current branch as main, then detach HEAD
`--main-branch <branch>`	Specify a different branch as main
`--no-detach`	Initialize without detaching HEAD

Examples

# Initialize with current branch as main
/bl-init

# Initialize with a specific branch as main
/bl-init --main-branch develop

Execution

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

Task(subagent_type="git-workflow:bl-init-expert",
     prompt="Initialize git-branchless: <options>")

Execution Instructions

Check Prerequisites
- Verify this is a git repository
- Check if git-branchless is installed
- Check if already initialized
Determine Main Branch
- Use current branch if no --main-branch specified
- Validate the branch exists
Initialize Git-Branchless
- Run git branchless init --main-branch <branch>
- Configure recommended settings
Detach HEAD (unless --no-detach)
- Run git checkout --detach
- This prepares you for the stacked commits workflow
Verify Installation
- Run git sl to confirm working
- Show current state with detached HEAD
Provide Next Steps
- Explain basic commands (git sl, git sync, git submit)

Interactive Flow

User: /bl-init

Agent: Initializing git-branchless...

Current branch: main
Repository: /path/to/project

Checking prerequisites...
✓ Git repository detected
✓ git-branchless is installed (v0.9.0)
✗ Not yet initialized

Initializing with main branch: main

$ git branchless init --main-branch main
Created config file at .git/branchless/config
Installed hooks at .git/hooks/
branchless: processing 1 update: main

Detaching HEAD for stacked workflow...
$ git checkout --detach

✓ Git-branchless initialized successfully!

Current state:
◆ abc1234 (main) Latest commit message
┃
● abc1234 (HEAD)  ← You are here (detached)

Ready to stack commits! Next steps:
1. Use `git record -m "msg"` to create commits
2. Use `git sl` to see your commit stack
3. Use `git sync --pull` to sync with remote
4. Use `git submit` to create/update PRs

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

bl-init is a skill published in the GitHub repository jpoutrin/product-forge (16 stars, last pushed 7mo ago), licensed MIT. It adds 16 tokens to every session and 1,049 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
