claudeguard 0.1.3

Claude Code security guard - an alternative Claude Code permission framework

claudeguard

claudeguard enhances Claude Code with automated security decisions using pattern matching and team-shareable profiles.

Why claudeguard?

Claude Code's permission prompts are great for security but repetitive for routine tasks. claudeguard automates common decisions while keeping you in control of sensitive operations.

How it works

claudeguard uses the PreToolUse Claude Code hook to intercept tool calls and override Claude Code's builtin permission logic

Features

• Pattern matching: Edit(src/**), Bash(/git status/), Bash(rm -rf*)
• Team sharing: Profiles stored in .claudeguard/profiles/
• Zero config: Works immediately with sensible rules

Quick Start

# Install
uv tool install claudeguard

# Setup in your project
cd your-claude-code-project
claudeguard install

# Use Claude Code normally
claude

How It Works

claudeguard matches tool calls against rules in .claudeguard/profiles/default.yaml:

rules:
  - pattern: "Read(*)"
    action: allow
  - pattern: "Edit(*.md)"
    action: allow
  - pattern: "Bash(/git (status|diff)/)"
    action: allow
  - pattern: "Edit(src/**)"
    action: ask
  - pattern: "Bash(rm -rf*)"
    action: deny
  - pattern: "*"
    action: ask

First matching rule wins. Actions: allow, ask, deny.

Commands

• claudeguard install - Setup in current project
• claudeguard status - Show configuration
• claudeguard create-profile - Create new profile
• claudeguard list-profiles - List profiles
• claudeguard switch-profile - Switch profile
• claudeguard delete-profile - Delete profile
• claudeguard uninstall - Remove from project

Pattern Examples

Pattern	Matches	Action
Read(*)	All file reads	allow
Edit(*.md)	Markdown files	allow
Bash(/git (status|diff)/)	Safe git commands	allow
Edit(src/**)	Code files	ask
Bash(rm -rf*)	Destructive commands	deny

Custom Profiles

Create profiles for different security levels:

# .claudeguard/profiles/strict.yaml
name: "strict-policy"
description: "Strict security for production"
rules:
  - pattern: "Read(*)"
    action: allow
  - pattern: "Edit(docs/**)"
    action: allow
  - pattern: "Edit(*)"
    action: ask
  - pattern: "Bash(/git (status|diff|log)/)"
    action: allow
  - pattern: "Bash(*)"
    action: deny
  - pattern: "*"
    action: deny
