A tool for managing stacked Git branches, where each branch depends on changes in another branch.

Use it to rebase or merge chains of dependent feature branches and maintain their branch order.

It reduces the manual work of updating several dependent branches when an earlier branch changes. This helps keep related pull requests, which are requests to review and merge code, aligned.

git-chain — Skill for Claude Code and Codex by dashed

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add dashed/claude-marketplace --skill git-chain

Clone the repo

git clone --depth 1 https://github.com/dashed/claude-marketplace

Made for: Claude Code, Codex.

Its marketplace also offers this one on its own, as the plugin git-chain — /plugin install git-chain after adding the marketplace above.

Origin unknown No closer match found in the catalogue.

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	$0.00056	$0.01726
Opus 5.5	$0.00022	$0.00690
Sonnet 5.5	$0.00011	$0.00345
Haiku 4.5	$0.00006	$0.00173

Measured 2mo ago against content hash 855735eb9ab1, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

git-chain 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 2mo 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.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

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.
