WorktreeCreate

WorktreeCreate is a hook for coding agents from avanturer/claude-bestpractice. Its token cost is not measured, scanned A, original, MIT.

An automatic action that runs when a Git worktree is created. A worktree is a separate working directory connected to the same Git repository.

In plain words
What is it for?
Use it in Git-based agent workflows that create worktrees for separate tasks or branches. It runs the repository's worktree-creation command.
Why use it?
It lets the project perform its setup or validation steps whenever a new isolated working directory is provisioned. This keeps new worktrees ready for use.

Hook

Part of the claude-bestpractice plugin — 3 skills, 3 commands, 1 agent, 10 hooks shipped together

One of 10 entries in hooks.json — they are configured in one file and arrive together.

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.

agentmods
npx agentmods add hooks/avanturer/claude-bestpractice/worktree-create
Clone the repo
git clone --depth 1 https://github.com/avanturer/claude-bestpractice

Or install claude-bestpractice, the plugin that ships this one along with the rest of its 3 skills, 3 commands, 1 agent, 10 hooks.

Security

Grade A, and why

WorktreeCreate 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 3d ago.

A static scan of the commands this hook runs, not an audit. A hook is shell that executes on your machine at the event it names, which is why every command in it is printed with what was found.

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 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.
