claudesidian: Skill for Claude Code

.agents/skills/git-worktrees/SKILL.md

git-worktrees is a skill for Claude Code, Codex from heyitsnoah/claudesidian. It costs 40 tokens per session (1,091 once invoked), scanned A, original, MIT.

A guide to Git worktrees, which let one repository have several working folders checked out on different branches. Each folder can be used independently while sharing the repository’s history.

In plain words
What is it for?
Use it to create isolated feature workspaces, inspect a pull-request branch, run long tasks separately, and remove or clean up worktrees after they are no longer needed.
Why use it?
It lets developers work on parallel features, reviews, or experiments without repeatedly switching branches or disturbing the main working folder.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is heyitsnoah/claudesidian's own configuration. It tells Claude Code and Codex how to work on claudesidian itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claudesidian configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is cp ../.env .env.local.

About the project

Claudesidian is a preconfigured Obsidian vault structure that lets Claude Code help manage a personal knowledge base as a thinking partner. It is for people who organize notes and other knowledge in Obsidian, with Git-based version control and optional integrations for image analysis and web research. The catalogue add-ons provide Claude Code skills, agents, hooks, and settings for working with this vault.

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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.

Security

Grade A, and why

git-worktrees 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.

Git Worktrees

Overview

Git worktrees create isolated workspaces sharing the same repository, allowing work on multiple branches simultaneously without switching. Each worktree is a separate directory with its own working tree, but they share the same .git history.

When to Use Worktrees

  • Parallel development: Work on feature A while feature B builds/tests
  • Code review: Check out PR branch without disrupting current work
  • Experiments: Try something risky without affecting main workspace
  • Long-running tasks: Keep main branch available while feature develops

Quick Reference

Action Command
List worktrees git worktree list
Create worktree git worktree add <path> -b <branch>
Create from existing branch git worktree add <path> <branch>
Remove worktree git worktree remove <path>
Prune stale worktrees git worktree prune

Creating Worktrees

New Feature Branch

# Create worktree with new branch
git worktree add .worktrees/my-feature -b feat/my-feature

# Or specify base branch
git worktree add .worktrees/my-feature -b feat/my-feature main

From Existing Branch

# Check out existing remote branch
git worktree add .worktrees/pr-review origin/fix-bug

# Check out existing local branch
git worktree add .worktrees/hotfix hotfix/urgent-fix

Directory Structure

project/
├── .git/                    # Shared git history
├── .worktrees/              # Convention: keep worktrees here
│   ├── feature-a/           # First worktree
│   └── feature-b/           # Second worktree
└── src/                     # Main worktree files

Setup After Creating Worktree

After creating a worktree, you typically need to:

cd .worktrees/my-feature

# Install dependencies
npm install  # or pnpm install, yarn, etc.

# Copy any required env files
cp ../.env .env.local

# Verify setup
npm test

Safety Rules

NEVER remove a worktree with uncommitted changes without confirmation.

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.
